*	Measures used in this release that are not based on accounting principles generally accepted in the United States of America (“non-GAAP”) are denoted with an asterisk and defined and reconciled to the most directly comparable GAAP measure in the “Definitions of Non-GAAP Measures” section of this document.

“Excellent execution of our operating plan led to increased growth and profitability in the first quarter of 2018. We also benefited from an unexpected decline in auto accident frequency, lower catastrophe losses and a reduction in federal taxes,” said Tom Wilson, Chairman, President and Chief Executive Officer of The Allstate Corporation. “Net income was $946 million, or $2.63 per share, reflecting good margins in the Property-Liability, Life and Benefits businesses and a lower tax rate. The recorded combined ratio of 88.0 was 4.9 points below last year. We are also pleased that the Allstate and Esurance brands increased policies in force, due to higher customer retention and increased new business. Allstate Benefits and SquareTrade continued to have strong growth.

“Progress was also made on all the 2018 Operating Priorities in the first quarter. Customers were better served as internal measures of Net Promoter Score increased, which supports higher customer retention and growth. Investments contributed $786 million of pre-tax income reflecting good results in the market and performance-based portfolios. Total portfolio return for the quarter was a negative 50 basis points as a 0.9% contribution from investment income was offset by a 1.4% decline in the current market value of the portfolio due to higher interest

rates, wider credit spreads and lower equity prices. Progress was also made in building long-term growth platforms and ensuring Allstate meets the needs of all of our stakeholders, as discussed in the recently released Prosperity Report,” concluded Wilson.

First Quarter 2018 Results


•	Total revenue of $9.8 billion in the first quarter of 2018 increased 1.3% compared to the prior year quarter.


◦	Property and casualty insurance premiums earned increased 4.1%.


◦	Life premiums and contract charges increased 3.9%.


◦	Net investment income increased 5.1%.


◦	Realized capital losses were $134 million compared to a gain of $134 million in the prior year quarter, which reduced year-over-year revenue growth by 2.8 points.

•

Net income applicable to common shareholders was $946 million, or $2.63 per diluted share, in the first quarter of 2018, compared to $666 million, or $1.79 per diluted share, in the first quarter of 2017. Adjusted net income* was $1.07 billion in the first quarter of 2018, compared to $608 million in the first quarter of 2017, as reduced catastrophe losses, a lower effective tax rate and improved underlying loss performance more than offset higher expenses.


•	Property-Liability underwriting income of $959 million was $411 million better than the prior year quarter. Lower catastrophe losses, increased premiums earned and lower auto accident frequency were partially offset by higher operating expenses, increased severity and lower favorable prior year reserve reestimates.

◦

The underlying combined ratio* of 84.2 for the first quarter of 2018 was essentially flat to the prior year quarter as improved auto insurance margins were offset by the impact of adverse weather in homeowners insurance. First quarter results were better than the annual outlook range of 86 to 88⁽¹⁾ as the continued reduction in accident frequency favorably impacted auto insurance profitability.


◦	Non-catastrophe prior year reserve releases of $55 million in the first quarter of 2018 included Allstate brand releases of $56 million, primarily driven by auto injury coverages.



Property-Liability Results
	Three months ended March 31,
(% to earned premiums)	2018	2017	pts Change
Recorded Combined Ratio	88.0	92.9	(4.9	)
Allstate Brand Auto	88.5	90.7	(2.2	)
Allstate Brand Homeowners	80.8	93.7	(12.9	)
Allstate Brand Other Personal Lines	89.0	93.1	(4.1	)

Allstate Brand Homeowners	63.5	61.3	2.2
Allstate Brand Other Personal Lines	83.3	78.8	4.5
Esurance	98.4	100.2	(1.8	)
Encompass	87.9	86.6	1.3

_________

⁽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.


◦	Allstate brand auto net written premium grew 5.5% in the first quarter of 2018, reflecting a 4.8% increase in average premium and a 0.3% increase in policies in force. Growth in policies in force was driven by continued improvement in the renewal ratio and higher new issued applications.


▪	The recorded combined ratio of 88.5 in the first quarter of 2018 was 2.2 points better than the prior year quarter, due to increased premiums earned, lower catastrophe losses and a broad-based decline in accident frequency. The underlying combined ratio* of 90.0 in the quarter was 0.9 points better than the prior year quarter.


◦	Allstate brand homeowners net written premium increased 4.4% in the first quarter of 2018 compared to the prior year quarter, due to increased average premium. Policies in force increased slightly compared to the prior year quarter, driven by improvement in the renewal ratio and increased new issued applications compared to the prior year quarter.

▪

The recorded combined ratio of 80.8 in the first quarter of 2018 was 12.9 points better than the prior year quarter, due to lower catastrophe losses and increased premiums earned, partially offset by unfavorable prior year reserve reestimates compared to favorable reserve reestimates in the first quarter of 2017. The underlying combined ratio* of 63.5 was 2.2 points higher than the prior year quarter, due to elevated underlying loss costs, mainly driven by adverse winter weather in the eastern part of the U.S.

◦

Allstate brand other personal lines net written premium of $375 million increased 1.9% in the first quarter of 2018 compared to the prior year quarter. The recorded combined ratio of 89.0 was 4.1 points better than the prior year quarter, primarily driven by lower catastrophe losses. The underlying combined ratio* of 83.3 in the first quarter of 2018 was 4.5 points higher than the prior year period, primarily due to elevated underlying loss costs.


◦	Esurance net written premium growth of 7.9% compared to the prior year quarter reflects increased average premium in auto and homeowners insurance, and a 1.1% increase in total policies in force. The strategy to drive broad-based growth across lines of business resulted in a 33.3% increase in homeowners policies in force and higher new issued auto applications and retention.


▪	The recorded combined ratio of 99.3 in the first quarter of 2018 was 3.1 points better than the prior year quarter, due to improvement in both the loss ratio and expense ratio. The underlying combined ratio* of 98.4 was 1.8 points better than the prior year quarter, as both auto and homeowners insurance results improved.

◦

Encompass net written premium declined 5.5% in the first quarter of 2018 compared to the prior year quarter, reflecting the continued execution of profit improvement plans. The recorded combined ratio of 98.4 in the first quarter of 2018 was 13.3 points better than the prior year quarter, due to lower catastrophe losses. The underlying combined ratio* of 87.9 for the first quarter was 1.3 points higher than the prior year quarter as a higher expense ratio more than offset improvement in the underlying loss ratio.


•	Service Businesses policies in force grew to 46.5 million, an increase of 11.7 million compared to the prior year quarter, driven by SquareTrade. Adjusted net loss of $5 million in the first quarter of 2018 was $5 million better than the first quarter of 2017, due to improved loss experience at SquareTrade, partially offset by investments in research and business expansion at Arity.

Total Revenues	$	313		$	247		26.7		%

Allstate Dealer Services	2			—			2
Arity	(4		)	1			(5		)


◦	SquareTrade revenue was $122 million in the first quarter, reflecting policies in force growth of 11.9 million compared to the first quarter of 2017 and the adoption of a new revenue recognition accounting standard. Adjusted net income is not impacted by the new accounting standard and was $2 million in the first quarter of 2018 due to improved loss experience.


◦	Allstate Roadside Services revenue in the first quarter of 2018 declined 5.1% compared to the prior year quarter, reflecting non-renewal of unprofitable third-party contracts. An adjusted net loss of $5 million was realized, due to lower premiums earned and higher loss costs, partially offset by lower expenses.


◦	Allstate Dealer Services revenue grew 6.7% compared to the first quarter of 2017, and adjusted net income was $2 million, reflecting improvement in loss costs.


◦	Arity had revenues of $21 million in the first quarter of 2018, largely related to contracts with affiliates. The adjusted net loss of $4 million represented continuing investments in business expansion and product development.

•

Allstate Life adjusted net income was $69 million in the first quarter of 2018, $10 million higher than the prior year quarter, primarily due to a lower effective tax rate and higher premiums and contract charges, partially offset by adverse mortality. Premiums and contract charges increased 1.9% in the first quarter compared to the prior year quarter, primarily related to growth in traditional life insurance and lower levels of reinsurance premiums ceded.


•	Allstate Benefits adjusted net income was $28 million in the first quarter of 2018, $6 million higher than the prior year quarter, primarily due to higher premiums and contract charges and a lower tax rate, partially offset by higher contract benefits. Premiums and contract charges increased 6.3% in the first quarter compared to the prior year quarter, due to 6.7% growth in policies in force.


•	Allstate Annuities adjusted net income was $35 million in the first quarter of 2018, $6 million higher than the prior year quarter, primarily due to higher performance-based income. Policies in force declined 8.5% in the first quarter of 2018 as the business continues to run off.


•	Allstate Investments $83 billion portfolio generated net investment income of $786 million in the first quarter, which was 5.1%, or $38 million, above the prior year quarter.

NM = not meaningful


◦	Market-based investments contributed $652 million of income in the first quarter of 2018, primarily from fixed-income securities.


◦	Performance-based investments generated income of $181 million in the first quarter of 2018, which increased 38.2% over the prior year quarter, primarily reflecting private equity asset appreciation and continued growth of the performance-based portfolio.

◦

Net realized capital losses were $134 million in the first quarter of 2018, compared to a gain of $134 million in the prior year quarter. Net realized losses for the quarter primarily consisted of declines in the valuation of equity investments of $83 million and losses on sales of $42 million. Beginning in 2018, equity valuation changes are included in net income due to the adoption of a new accounting standard.


◦	Unrealized net capital gains decreased $1 billion, post adoption of the new accounting standard, from prior year-end as higher market yields decreased fixed-income valuations.


◦	Total return on the investment portfolio was (0.5)% for the first quarter of 2018 as the 0.9% contribution from net investment income was more than offset by a 1.4% decline in the portfolio’s current market value due to higher interest rates, credit spreads and lower equity prices.

Proactive Capital Management

“Allstate returned $465 million of capital to our shareholders during the first quarter through a combination of $132 million in common stock dividends and repurchasing $333 million of outstanding shares. As of March 31, 2018, there was $935 million remaining on the $2 billion common share repurchase authorization,” said Mario Rizzo, Chief Financial Officer.

“During the first quarter, Allstate issued $575 million of noncumulative perpetual preferred stock and $500 million in floating rate senior notes. The proceeds of these issuances are for general corporate purposes, including the redemption, repayment or repurchase of certain preferred stock and debt. Our adjusted net income return on common shareholders’ equity* of 15.0% for the 12 months ended March 31, 2018 was an increase of 3.1 points compared to the prior year period. Book value per diluted common share of $58.64 was 11.9% higher than March 31, 2017,” concluded Rizzo.

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 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 first quarter 2018 and 35% for first quarter 2017 and are reported net with 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. 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 reconcile the respective combined ratio to the underlying combined ratio.

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. Bodily injury claim process changes in the second half of 2016 related to enhanced documentation of injuries and related medical treatments are having a related impact on paid claim frequency and severity due to payment mix and claim closure patterns. These process changes and the related impacts on the percent change in paid claim frequency and severity have begun to moderate, but are still impacting comparative trends. 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. Statistics presented for Allstate brand exclude excess and surplus lines. 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. 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. 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. Calculated by annualizing net earned premium reported in the quarter and year-to-date divided by policies in force at quarter end. Average underlying loss (incurred pure premium) and expense is calculated as the underlying combined ratio multiplied by the annualized average premium.

The DAC and DSI adjustment balance represents the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized gains or losses in the respective product portfolios were realized. The comparison of percentages from period to period may be distorted by investment transactions such as sales, purchases and impairment write-downs. Unrealized net capital gains and losses for limited partnership interests represent the Company's share of EMA limited partnerships' other comprehensive income. Fair value and amortized cost are not applicable. The insurance reserves adjustment represents the amount by which the reserve balance would increase if the net unrealized gains in the applicable product portfolios were realized and reinvested at current lower interest rates, resulting in a premium deficiency. This adjustment primarily relates to structured settlement annuities with life contingencies (a type of immediate fixed annuities). The Allstate Corporation 1Q18 Supplement 44

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. Total return on investment portfolio is calculated from GAAP results, including the total of net investment income, realized capital gains and losses, the change in unrealized net capital gains and losses, and the change in the difference between fair value and carrying value of mortgage loans, cost method limited partnerships for periods prior to 2018, bank loans and agent loans divided by the average fair value balances. Average investment balances for the quarter are calculated as the average of the current and prior quarter investment balances. Year-to-date average investment balances are calculated as the average of investment balances at the beginning of the year and the end of each quarter during the year. For purposes of the average investment balances calculation, unrealized capital gains and losses on fixed income securities are excluded and equity securities investment balances are at cost.

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.

• 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. 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 Auto and Homeowners Underlying Loss and Expense". 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: 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", "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", and "SquareTrade Profitability Measures". The Allstate Corporation 1Q18 Supplement 51

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 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 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, 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".

Gross claim frequency and paid claim severity indexed to 2013 equals the current year gross claim frequency or paid claim severity plus 100%, times the prior year indexed amount beginning with 100% in 2013 rounded. 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). The percent change in gross claim frequency is calculated as the amount of increase or decrease in the gross claim frequency in the current period compared to the prior period shown above; divided by the prior period gross claim frequency. The percent change in Q1 2018 is calculated using the gross claim frequency for the three months ended March 31, 2018 compared to the same amounts for the twelve months ended December 31, 2017. 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 the paid claim severity in the current period compared to the prior period shown above; divided by the prior period paid claim severity.
