Reportable Segments

Note 3 Reportable Segments

Measuring segment profit or loss

The measure of segment profit or loss used in evaluating performance is underwriting income for the Allstate Protection and Run-off Property-Liability segments and adjusted net income for the Protection Services, Allstate Health and Benefits and Corporate and Other segments.

Allstate Protection and Run-off Property Liability segments comprise Property-Liability. The Company does not allocate investment income, net gains and losses on investments and derivatives, or assets to the Allstate Protection and Run-off Property Liability segments. Management reviews assets at the Property-Liability, Protection Services, Allstate Health and Benefits, and Corporate and Other levels for decision-making purposes.

Underwriting income is calculated as premiums earned and other revenue, less claims and claims expenses (“losses”), amortization of DAC, operating costs and expenses, amortization or impairment of

purchased intangibles and restructuring and related charges as determined using GAAP.

Adjusted net income is net income (loss) applicable to common shareholders, excluding:

• Net gains and losses on investments and derivatives

• Pension and other postretirement remeasurement gains and losses

• Amortization or impairment of purchased intangibles

• Gain or loss on disposition

• 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

• Income tax expense or benefit on reconciling items

A reconciliation of these measures to net income (loss) applicable to common shareholders is provided below.
