Note 1 | General
Basis of presentation The accompanying consolidated financial statements include the accounts of The Allstate Corporation (the “Corporation”) and its wholly owned subsidiaries, primarily Allstate Insurance Company (“AIC”), a property and casualty insurance company with various property and casualty and life and investment subsidiaries, including Allstate Life Insurance Company (“ALIC”) (collectively referred to as the “Company” or “Allstate”). These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Nature of operations Allstate is engaged, principally in the United States, in the property and casualty insurance and life insurance businesses. Allstate is one of the country’s largest personal property and casualty insurers and is organized into seven reportable segments: Allstate Protection, Discontinued Lines and Coverages, Protection Services (previously Service Businesses), Allstate Life, Allstate Benefits, Allstate Annuities, and Corporate and Other. Allstate’s primary business is the sale of private passenger auto and homeowners insurance. The Company also offers several other personal property and casualty insurance products, select commercial property and casualty coverages, consumer product protection plans, device and mobile data collection services and analytic solutions using automotive telematics information, roadside assistance, finance and insurance products, life insurance, voluntary accident and health insurance and identity protection. Allstate primarily distributes its products through exclusive agents, financial specialists, independent agents and brokers, major retailers, contact centers and the internet. Risks and uncertainties Allstate has exposure to catastrophic events, including wind and hail, wildfires, tornadoes, hurricanes, tropical storms, earthquakes, volcanic eruptions, terrorism and industrial accidents. Catastrophes, an inherent risk of the property and casualty insurance business, have contributed, and will continue to contribute, to material year-to-year fluctuations in the Company’s results of operations and financial position (see Note 8). The nature and level of catastrophic loss experienced in any period cannot be predicted and could be material to results of operations and financial position. The Company considers the following categories and locations to be the greatest areas of potential catastrophe losses: •Wildfires — California, Oregon, Colorado, and Texas •Hurricanes — Major metropolitan centers in counties along the eastern and gulf coasts of the United States •Wind/Hail, Rain and Tornado — Texas, Illinois, Georgia and Colorado •Earthquakes and fires following earthquakes —Major metropolitan areas near fault lines in the states of California, Oregon, Washington, South Carolina, Missouri, Kentucky and Tennessee Recent development The Novel Coronavirus Pandemic or COVID-19 (“Coronavirus”) resulted in governments worldwide enacting emergency measures to combat the spread of the virus. These measures, which have included the implementation of travel restrictions, government-imposed shelter-in-place orders, quarantine periods, social distancing, and restrictions on large gatherings, have caused material disruption to businesses globally, resulting in increased unemployment, a recession and increased economic uncertainty. Additionally, there is no way of predicting with certainty how long the pandemic might last, including the potential for restrictions being restored or new restrictions being implemented that could result in further economic volatility. The magnitude and duration of the global pandemic and the impact of actions taken by governmental authorities, businesses and consumers, including timing of vaccine distribution, to mitigate health risks create significant uncertainty. The Company will continue to closely monitor and proactively adapt to developments and changing conditions. Currently, it is not possible to reliably estimate the length and severity of the pandemic or its impact to the Company’s operations, but the effects could be material and may continue, emerge, evolve or accelerate in 2021.
