“Allstate continues to deliver strong operating results while building the future. The strategy to grow market share in personal protection is working with growth in auto and home insurance, workplace benefits and protection plans. We also expanded identity protection by acquiring InfoArmor. Full year revenues increased to $40.7 billion, excluding realized capital gains and losses. Policies in force increased 2.4% in Allstate Protection insurance, and the addition of 30 million SquareTrade protection policies brought our total to over 113 million. Arity, our connected car platform, is now collecting 10 billion miles of driving data per month through expansion of third-party connectivity,” said Tom Wilson, Chair, President and Chief Executive Officer of The Allstate Corporation.

“Operating results for 2018 were strong with achievement of the five Operating Priorities. Customers were better served with increased net promoter scores, which supported higher growth. Attractive returns were generated as the underlying combined ratio was better than the range established at the beginning of the year. Adjusted net income* was $8.07 per share, 20.3% higher than 2017, and adjusted net income return on common shareholders’ equity* was 14.8%. Reflecting these results, the underlying combined ratio* for the Property-Liability business is expected to be between 86 and 88⁽¹⁾ in 2019,” concluded Wilson.

Full Year 2018 Financial Highlights

• Allstate delivered on the 2018 Operating Priorities, which focus on both near-term performance and long-term value creation.

◦ Better Serve Customers: The Net Promoter Score, which measures how likely customers are to recommend us, increased for all major businesses.

◦ Achieve Target Economic Returns on Capital: Adjusted net income return on shareholders’ equity* was 14.8% for 2018, primarily driven by strong Property-Liability underwriting income. Allstate Life and Allstate Benefits also generated good returns.

◦ Grow Customer Base: Allstate Protection policies in force increased by 2.4% in 2018 to 33.3 million due to a 2.3% increase in the Allstate brand and 10.4% in the Esurance brand. Consolidated policies in force grew to 113.9 million in 2018.

◦ Proactively Manage Investments: Total return on the $81 billion investment portfolio was 0.8% during a volatile 2018, reflecting lower equity and fixed income valuations.Net investment income of $3.2 billion was 4.7% lower than 2017, primarily due to decreased performance-based income compared to a very strong 2017.

◦ Build Long-Term Growth Platforms: SquareTrade continued its rapid growth in 2018 with a 77.1% increase in policies, and acquired PlumChoice to broaden its service offering. In the fourth quarter, Allstate acquired InfoArmor, a fast growing identity protection provider.

Fourth Quarter 2018 Results

• Total revenue of $9.48 billion in the fourth quarter of 2018 decreased 5.8% compared to the prior year quarter.

◦ Property-Liability insurance premiums earned increased 5.7%.

◦ Service Businesses revenue increased 27.1%.

◦ Life premiums and contract charges increased 4.0%.

◦ Net investment income decreased 13.9%.

◦ Realized capital losses reduced revenues by $894 million.

• Net loss applicable to common shareholders was $312 million, or $0.91 per diluted share, in the fourth quarter of 2018, compared to net income of $1.22 billion, or $3.35 per diluted share, in the fourth quarter of 2017. Realized capital losses, principally from mark to market losses on the public equity portfolio, more than offset adjusted net income* of $430 million in the fourth quarter. Fourth quarter adjusted net income* was $332 million below the prior year quarter, driven by higher catastrophe losses, lower net investment income and a larger pension settlement charge, partially offset by higher premiums earned and reduced auto insurance accident frequency.

_________

⁽¹⁾ A reconciliation of this non-GAAP measure to the combined ratio, a GAAP measure, is not possible on a forward-looking basis because it is not possible to provide a reliable forecast of catastrophes, and prior year reserve reestimates are expected to be zero because reserves are determined based on our best estimate of ultimate loss reserves as of the reporting date.

2

• Property-Liability underwriting income of $249 million in the fourth quarter of 2018 was $466 million below the prior year quarter, driven by higher catastrophe losses, increased claim severity and lower favorable prior year reserve reestimates, partially offset by increased premiums earned and reduced auto accident frequency.

◦ The recorded combined ratio of 97.0 for the fourth quarter was 6.0 points above the prior year quarter, primarily driven by catastrophe losses of $963 million, net of reinsurance recoveries of more than $700 million. Hurricane Michael and the Camp and Woolsey wildfires in California accounted for approximately 85% of recorded catastrophe losses in the quarter.

◦ The underlying combined ratio* of 85.8 for the full year 2018 was within the revised annual outlook range of 85 to 87. The underlying combined ratio* of 86.8 for the fourth quarter of 2018 was 1.1 points higher than the prior year quarter, primarily due to adverse non-catastrophe weather related losses in Allstate and Encompass brand homeowners insurance and higher auto claim severity.

◦ Allstate brand auto insurance net written premium grew 6.4% in the fourth quarter of 2018 compared to the prior year quarter, reflecting a 2.7% increase in policies in force and higher average premium. The recorded combined ratio of 92.9 in the fourth quarter of 2018 was 1.0 point higher than the prior year quarter. The underlying combined ratio* of 93.6 in the quarter was 0.6 points better than the prior year quarter, due to higher earned premium and lower accident frequency, partially offset by higher physical damage claim severity.

◦ Allstate brand homeowners insurance net written premium grew 4.9% in the fourth quarter of 2018 compared to the prior year quarter and continues to generate attractive returns. The recorded combined ratio of 105.7 in the fourth quarter was 20.3 points higher than the prior year quarter, primarily driven by catastrophe losses of $798 million, compared to $480 million in the prior year quarter. For the full year 2018, the recorded combined ratio was 93.3 and the underlying combined ratio* was 63.5.

◦ Esurance brand net written premium grew 16.3% and policies in force increased 10.4% in the fourth quarter of 2018 compared to the prior year quarter. The recorded combined ratio of 101.8 in the fourth quarter of 2018 was 1.6 points higher than the prior year quarter, driven by elevated claim severity, increased advertising spend and higher catastrophe losses, partially offset by earned premium growth. The underlying combined ratio* of 99.8 in the fourth quarter was in line with the prior year quarter.

◦ Encompass brand net written premium increased 1.6% in the fourth quarter of 2018 compared to the prior year quarter. The recorded combined ratio of 102.0 in the fourth quarter of 2018 was 4.4 points better than the prior year quarter. The underlying combined ratio* of 101.6 in the fourth quarter was 15.2 points higher than the prior year quarter, primarily due to current year reserve strengthening in auto insurance and adverse non-catastrophe weather related losses in homeowners insurance.

• Service Businesses policies in force grew to 74.2 million, and revenues increased 27.1% compared to the prior year quarter. Adjusted net income was $6 million, an increase of $30 million compared to the prior year quarter.

• Allstate Benefits adjusted net income was $25 million in the fourth quarter of 2018, $5 million higher than the prior year quarter, primarily due to increased premiums and a lower effective tax rate, partially offset by higher expenses.

• Allstate Annuities adjusted net income was $31 million in the fourth quarter of 2018, $24 million lower than the prior year quarter, primarily due to lower performance-based investment income.

• Allstate Investments $81 billion portfolio generated net investment income of $786 million in the fourth quarter, which declined $127 million from the prior year quarter due to lower performance-based income.

NM = not meaningful

◦ Total return on the investment portfolio of -0.2% for the fourth quarter of 2018 and 0.8% for the year included a stable contribution from net investment income but was impacted by lower fixed income and equity valuations.

◦ Market-based investments contributed $696 million of income in the fourth quarter of 2018, an increase of 4.8% compared to the prior year quarter, primarily from higher bond yields and duration extension of the fixed income portfolio.

◦ Performance-based investments generated income of $145 million in the fourth quarter of 2018, a decrease of 51% over a strong prior year quarter, primarily reflecting a lower number of sales of underlying investments.

◦ Net realized capital losses were $894 million in the fourth quarter of 2018, compared to gains of $127 million in the prior year quarter. Net realized losses for the quarter primarily related to lower valuation of equity investments.

◦ Unrealized net capital gains decreased $11 million from the third quarter, as higher market yields resulted in lower fixed income valuations.

Proactive Capital Management

“Allstate provided excellent cash returns to shareholders in 2018 while broadening our business model through acquisitions. We returned $2.8 billion to common shareholders through a combination of $2.2 billion in common share repurchases and $614 million in common stock dividends,” said Mario Rizzo, Chief Financial Officer. “We continued to strategically deploy capital in the fourth quarter, redeeming $385 million of our Series C Preferred Stock, completing the $525 million acquisition of InfoArmor and $30 million acquisition of PlumChoice, and executing a $1 billion accelerated share repurchase program as part of our $3 billion share repurchase authorization.”

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 incomeapplicable 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 services 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.

The following tables reconcile net income applicable to common shareholders and adjusted net income. Beginning January 1, 2018, the Tax Legislation reduced the U.S. corporate income tax rate from 35% to 21%. Taxes on adjustments to reconcile net income applicable to common shareholders and adjusted net income generally use a 21% effective tax rate for 2018 and 35% for 2017 and are reported net of income taxes as the reconciling adjustment.

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.

Combined ratio excluding the effect of catastrophes, prior year reserve reestimates and 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, and 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 and 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, which could increase or decrease current year net income. 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.

The following tables reconcilethe respective combined ratio to the underlying combined ratio. Underwriting margin is calculated as 100% minus the combined ratio.

(2) Life premiums and contract charges are reported in the Allstate Life, Allstate Benefits and Allstate Annuities results and include life insurance, voluntary accident and health insurance, and annuity products. (3) Other revenue primarily represents fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, fee-based services and other revenue transactions. (4) On December 22, 2017, Public Law 115-97, known as the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) became effective, permanently reducing the U.S. corporate income tax rate from 35% to 21% beginning January 1, 2018. As a result, the corporate tax rate is not comparable between periods. (5) In accordance with GAAP, the quarter and year-to-date per share amounts are calculated discretely. Therefore, the sum of each quarter may not equal the year-to-date amount. (6) Includes a $2 million Tax Legislation expense for the quarter ended December 31, 2018, a $31 million benefit for the quarter ended September 30, 2018, and a $506 million benefit for the year ended December 31, 2017.

(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) Annualized Average Premium is 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.

(4) Year-to-date pre-tax yield is calculated as annualized year-to-date investment income, before investment expense divided by the average of investment balances at the beginning of the year and the end of each quarter during the year. For the purposes of the pre-tax yield calculation, income for directly held real estate and other consolidated investments is net of investee level expenses (depreciation and asset level operating expenses reported in investment expense). Fixed income securities investment balances exclude unrealized capital gains and losses. Equity securities investment balances use cost in the calculation.

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 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 and 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 which could increase or decrease current year income. 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 4Q18 Supplement 59

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", "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 average of equity at the beginning and at the end of the 12-months, 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 average 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".
