Property and casualty programs are grouped by the following characteristics:

1.Indemnification programs - industry pools, facilities or associations that are governed by state insurance statutes or regulations or the federal government.

2.Catastrophe reinsurance programs - reinsurance protection for catastrophe exposure nationwide and by specific states, as applicable.

3.Other reinsurance programs - reinsurance protection for asbestos, environmental and other liability exposures as well as commercial lines, including shared economy.

Property and casualty reinsurance is in place for the Allstate Protection, Run-off lines and Protection Services segments. The Company purchases reinsurance after evaluating the financial condition of the reinsurer as well as the terms and price of coverage.

Indemnification programs

The Company participates in state-based industry pools or facilities mandating participation by insurers offering certain coverage in their state, including the Michigan Catastrophic Claims Association (“MCCA”), the New Jersey Property-Liability Insurance Guaranty Association (“PLIGA”), the North Carolina Reinsurance Facility (“NCRF”) and the Florida Hurricane Catastrophe Fund (“FHCF”). When the Company pays qualifying claims under the coverage indemnified by a state’s pool or facility, the Company is reimbursed for the qualifying claim losses and expenses. Each state pool or facility may assess participating companies to collect sufficient amounts to meet its total indemnification requirements. The enabling legislation for each state’s pool or facility compels the pool or facility only to indemnify participating companies for qualifying claim losses and expenses; the state pool or facility does not underwrite the coverage or take on the ultimate risk of the indemnified business. As a pass through, these pools or facilities manage the receipt of assessments paid by participating companies and

payment of indemnified amounts for covered claims presented by participating companies. The Company has not had any credit losses related to these indemnification programs.

State-based industry pools or facilities

Michigan Catastrophic Claims Association The MCCA is a statutory indemnification mechanism for member insurers’ qualifying personal injury protection claims paid for the unlimited lifetime medical benefits above the applicable retention level for qualifying injuries from automobile, motorcycle and commercial vehicle accidents. Indemnification recoverables on paid and unpaid claims, including IBNR, as of December 31, 2022 and 2021 include $6.72 billion and $6.70 billion, respectively, from the MCCA for its indemnification obligation.

The MCCA is funded by annually assessing participating member companies actively writing motor vehicle coverage in Michigan on a per vehicle basis that is currently $86 per vehicle insured for unlimited personal injury protection (“PIP”) coverage. The MCCA’s calculation of the annual assessment is based upon the total of members’ actuarially determined present value of expected payments on lifetime claims by all persons expected to be catastrophically injured in that year and ultimately qualify for MCCA reimbursement, its operating expenses, and adjustments for the amount of excesses or deficiencies in prior assessments. The MCCA has also included in its calculation, the impacts of the auto insurance reforms which have begun to phase in since their passage in June 2019, including the PIP medical fee schedule that became effective July 2, 2021. The assessment is incurred by the Company as policies are written and recovered as a component of premiums from the Company’s customers.

The MCCA indemnifies qualifying claims of all current and former member companies (whether or not actively writing motor vehicle coverage in Michigan) for qualifying claims and claims expenses incurred while the member companies were actively writing the mandatory PIP coverage in Michigan. Member

companies actively writing automobile coverage in Michigan include the MCCA annual assessments in determining the level of premiums to charge insureds in the state.

As required for member companies by the MCCA, the Company reports covered paid and unpaid claims to the MCCA when estimates of loss for a reported claim are expected to exceed the retention level, the claims involve certain types of severe injuries, or there are litigation demands received suggesting the claim value exceeds certain thresholds. The retention level is adjusted upward every other MCCA fiscal year by the lesser of 6% or the increase in the Consumer Price Index. The retention level will be $600 thousand per claim for the fiscal two-years ending June 30, 2023 compared to $580 thousand per claim for the fiscal two-years ending June 30, 2021.

The MCCA is obligated to fund the ultimate liability of member companies’ qualifying claims and claim expenses. The MCCA does not underwrite the insurance coverage or hold any underwriting risk.

The MCCA indemnifies members as qualifying claims are paid and billed by members to the MCCA. Unlimited lifetime covered losses result in significant levels of ultimate incurred claim reserves being recorded by member companies along with offsetting indemnification recoverables. Disputes with claimants over coverage on certain reported claims can result in additional losses, which may be recoverable from the MCCA, excluding litigation expenses. There is currently no method by which insurers are able to obtain the benefit of managed care programs to reduce claims costs through the MCCA.

The MCCA annual assessments fund current operations and member company reimbursements. The MCCA prepares statutory-basis financial statements in conformity with accounting practices prescribed or permitted by the State of Michigan Department of Insurance and Financial Services (“MI DOI”). The MI DOI has granted the MCCA a statutory permitted practice that expires in June 30, 2025 to discount its liabilities for loss and loss adjustment expense. As of June 30, 2022, the date of its most recent annual financial report, the MCCA had cash and invested assets of $21.82 billion and an accumulated deficit of $3.68 billion. The permitted practice reduced the accumulated deficit by $44.89 billion. As a result of this deficit, there will be an additional assessment of $48 per passenger and commercial vehicle and motorcycle insured beginning July 1, 2023 with varying assessments for commercial fleet and historical vehicles.

As a result of the auto insurance reforms passed in June 2019, the MCCA announced on November 3, 2021 that the surplus reported for the fiscal year ended June 30, 2021 had increased beyond a level necessary to safely cover its expected losses and expenses and will return a portion of its surplus to its member insurance companies as a pass-through to issue a refund of $400 per vehicle and $80 per historical vehicle to the policyholders. At the time the returned surplus was received, a liability was recorded until the refunds were

disbursed to the policyholders. All refunds have been sent to policyholders as of December 31, 2022.

New Jersey Property-Liability Insurance Guaranty Association PLIGA serves as the statutory administrator of the Unsatisfied Claim and Judgment Fund (“UCJF”), Workers’ Compensation Security Fund and the New Jersey Surplus Lines Insurance Guaranty Fund.

In addition to its insolvency protection responsibilities, PLIGA reimburses insurers for unlimited excess medical benefits (“EMBs”) paid in connection with PIP claims in excess of $75,000 for policies issued or renewed prior to January 1, 1991, and limited EMB claims in excess of $75,000 and capped at $250,000 for policies issued or renewed on or after January 1, 1991, to December 31, 2003.

A significant portion of the incurred claim reserves and the recoverables can be attributed to a small number of catastrophic claims. Assessments paid to PLIGA for the EMB program totaled $7 million in 2022. The amounts of paid and unpaid recoverables as of December 31, 2022 and 2021 were $330 million and $371 million, respectively.

PLIGA annually assesses all admitted property and casualty insurers writing covered lines in New Jersey for PLIGA indemnification and expenses. PLIGA assessments may be recouped as a surcharge on premiums collected. PLIGA does not ultimately retain underwriting risk as it assesses member companies for their expected qualifying losses to provide funding for payment of its indemnification obligation to member companies for their actual losses. As a pass through, PLIGA facilitates these transactions of receipt of assessments paid by member companies and payment to member companies for covered claims presented by them for indemnification. As of December 31, 2021, the date of its most recent annual financial report, PLIGA had a fund balance of $268 million.

As statutory administrator of the UCJF, PLIGA provides compensation to qualified claimants for personal injury protection, bodily injury, or death caused by private passenger automobiles operated by uninsured or “hit and run” drivers. The UCJF also provides private passenger pedestrian personal injury protection benefits when no other coverage is available.

PLIGA annually collects a UCJF assessment from all admitted property and casualty insurers writing motor vehicle liability insurance in New Jersey for UCJF indemnification and expenses. UCJF assessments can be expensed as losses recoverable in rates as appropriate. As of December 31, 2021, the date of its most recent annual financial report, the UCJF fund had a balance of $62 million.

North Carolina Reinsurance Facility The NCRF provides automobile liability insurance to drivers that private market insurers are not otherwise willing to insure. All insurers licensed to write automobile insurance in North Carolina are members of the NCRF. Premiums, losses and expenses are assigned to the NCRF. North Carolina law allows the NCRF to recoup

operating losses for certain insureds through a surcharge to policyholders. As of September 30, 2022, the NCRF reported a deficit of $148 million in members’ equity. The NCRF implemented a loss recoupment surcharge on all private passenger and commercial fleet policies effective October 1, 2022, through March 31, 2023. Member companies are assessed the recoupment surcharge. The loss recoupment surcharge will be adjusted on April 1, 2023 and discontinued once losses are recovered. The NCRF results are shared by the member companies in proportion to their respective North Carolina automobile liability writings. For the fiscal year ending September 30, 2022, net loss was $81 million, including $1.1 billion of earned premiums, $302 million of certain private passenger auto risk recoupment and $37 million of member loss recoupments. As of December 31, 2022, the NCRF recoverables on paid claims is $52 million and recoverables on unpaid claims is $240 million. Paid recoverable balances, if covered, are typically settled within sixty days of monthly filing.

Florida Hurricane Catastrophe Fund Allstate subsidiaries Castle Key Insurance Company (“CKIC”) and Castle Key Indemnity Company (“CKI”, and together with CKIC, “Castle Key”) participate in the mandatory coverage provided by the FHCF and therefore have access to reimbursement for certain qualifying Florida hurricane losses from the FHCF. Castle Key has exposure to assessments and pays annual premiums to the FHCF for this reimbursement protection. The FHCF has the authority to issue bonds to pay its obligations to participating insurers in excess of its capital balances. Payment of these bonds is funded by emergency assessments on all property and casualty premiums in the state, except workers’ compensation, medical malpractice, accident and health insurance and policies written under the National Flood Insurance Program (“NFIP”). The FHCF emergency assessments are limited to 6% of premiums per year beginning the first year in which reimbursements require bonding, and up to a total of 10% of premiums per year for assessments in the second and subsequent years, if required to fund additional bonding. The FHCF has not issued an emergency assessment since 2015.

Annual premiums earned and paid under the FHCF agreement were $24 million, $15 million and $9 million in 2022, 2021 and 2020, respectively. Qualifying losses were $74 million, $13 million and $15 million in 2022, 2021 and 2020, respectively. The Company has access to reimbursement provided by the FHCF for 90% of qualifying personal property losses that exceed its current retention of $153 million for the two largest hurricanes and $51 million for other hurricanes, up to a maximum total of $350 million, effective from June 1, 2022 to May 31, 2023. The amounts recoverable from the FHCF totaled $96 million and $25 million as of December 31, 2022 and 2021, respectively.

Federal Government - National Flood Insurance Program NFIP is a program administered by the Federal Emergency Management Agency (“FEMA”) whereby the Company sells and services NFIP flood insurance policies as an agent of FEMA and receives

fees for its services. The Company is fully indemnified for claims and claim expenses and does not retain any ultimate risk for the indemnified business. The federal government is obligated to pay all claims and certain allocated loss adjustment expenses in accordance with the arrangement.

Congressional authorization for the NFIP is periodically evaluated and may be subjected to freezes, including when the federal government experiences a shutdown. FEMA has a NFIP reinsurance program to manage the future exposure of the NFIP through the transfer of risk to private reinsurance companies and capital market investors. Congress is evaluating the funding of the program as well as considering reforms to the program that would be incorporated in legislation to reauthorize the NFIP. As of June 30, 2022, the NFIP owes $20.5 billion to the U.S. Treasury.

The amounts recoverable as of December 31, 2022 and 2021 were $145 million and $34 million, respectively. Premiums earned under the NFIP include $319 million, $350 million and $261 million in 2022, 2021 and 2020, respectively. Qualifying losses incurred include $435 million, $267 million and $87 million in 2022, 2021 and 2020, respectively.

Catastrophe reinsurance

The Company’s reinsurance program is designed to provide reinsurance protection for catastrophes resulting from multiple perils including hurricanes, windstorms, hail, tornadoes, winter storms, wildfires, earthquakes and fires following earthquakes.

•The Company purchases reinsurance from traditional reinsurance companies as well as the insurance-linked securities (“ILS”) market.

•The majority of the Company’s program comprises multi-year contracts, primarily placed in the traditional reinsurance market, such that generally one-third of the program is renewed every year.

•Coverage is generally purchased on a broad geographic, product line and multiple peril loss basis.

•Florida personal lines property is covered by a separate agreement, as the risk of loss is different and the Company’s subsidiaries operating in this state are separately capitalized.

•When applicable, reinsurance reinstatement premiums are recognized in the same period as the loss event that gave rise to the reinstatement premium and are recorded in claims and claims expense in the consolidated statements of operations.

The Company’s current catastrophe reinsurance program supports the Company’s risk tolerance framework which utilizes a modeled 1-in-100 annual aggregate limit for catastrophe losses from hurricanes, earthquakes and wildfires of $2.5 billion, net of reinsurance.

The program includes coverage for losses to personal lines property, personal lines automobile, commercial lines property or commercial lines automobile arising out of multiple perils, in addition to hurricanes and earthquakes. These reinsurance agreements are part of the catastrophe management strategy, which is intended to provide shareholders an acceptable return on the risks assumed in the property business, and to reduce variability of earnings, while providing protection to customers. The Company has the following catastrophe reinsurance agreements in effect as of December 31, 2022.

The Nationwide Excess Catastrophe Reinsurance Program (the “Nationwide Program”) provides coverage up to $7.01 billion of losses less a $500 million retention, and is subject to the percentage of reinsurance placed in each of its agreements. Property business in the state of Florida is excluded from this program. Separate reinsurance agreements address the distinct needs of separately capitalized legal entities. The Nationwide Program includes reinsurance agreements with both the traditional and ILS markets as described below:

•The traditional market multi-year placements provide limits totaling $3.89 billion for catastrophe losses arising out of multiple perils and are comprised of the following:

–$3.56 billion of placed limits attaching at $500 million, exhausting at $3.75 billion, with a 5% co-participation. Coverage is provided in four contracts with one annual reinstatement of limits. 31.7% of the first $250 million in excess of $500 million is retained by Allstate.

•ILS placements provide $1.55 billion of placed limits, with no reinstatement of limits, and are comprised of the following:

–Five contracts providing occurrence coverage of $950 million of placed limits, reinsuring losses in all states except Florida caused by named storms, earthquakes and fire following earthquakes, severe weather, wildfires, and other naturally occurring or man-made events determined to be a catastrophe by the Company.

–Three contracts providing occurrence and aggregate coverage of $425 million of placed limits, also provide that for each annual period beginning April 1, Allstate declared catastrophes to personal lines property and automobile business can be aggregated to erode the aggregate retention and qualify for coverage under the aggregate limits. Recoveries are limited to the ultimate net loss from the reinsured event.

–One contract, providing aggregate coverage of $175 million of placed limits.

•Traditional single-year placements provide $640 million of placed limits, filling capacity around the traditional market and insurance-linked securities multi-year placements:
