Segment Information
3. Segment Information
AIG has three reportable segments, North America Commercial, International Commercial and Global Personal. Our chief executive officer and chief financial officer are our chief operating decision makers (CODMs) and use underwriting income (loss) measure to benchmark and assess AIG's performance by segment and in establishing management’s compensation. Our General Insurance business (General Insurance) consists of our three segments and the Net investment income related to our insurance operations.
NORTH AMERICA COMMERCIAL
The North America Commercial segment consists of insurance businesses and operations in the United States, Canada and Bermuda.

The International Commercial segment consists of insurance businesses and operations in Middle East and Africa (EMEA region), the United Kingdom, Japan, Europe, Asia Pacific, Latin America and Caribbean, and China. The International Commercial segment also includes the results of Talbot Holdings Ltd. (Talbot) as well as AIG’s Global Specialty business.

The segments consist of the following products:

–Global Personal consists of Global Accident & Health and Personal Lines.
OTHER OPERATIONS
Other Operations predominantly consists of Net Investment Income from our AIG Parent liquidity portfolio, Corebridge Financial, Inc. (Corebridge) dividend income, corporate General operating expenses, and Interest expense.
SEGMENT RESULTS
Management uses Underwriting income (loss) as the basis for the segment performance reviews. AIG calculates Underwriting income (loss) by subtracting Losses and loss adjustment expense incurred, Amortization of deferred policy acquisition costs (DAC), Other acquisition cost, and General operating expense from Net premiums earned. Assets by reportable segment are not used by the CODMs for purposes of making decisions about allocating resources to the segment and assessing its performance.
