Summary of Line of Business Results

The following is a summary of our line of business results for the periods indicated. The "Other" columns represent amounts that are not allocated to our two lines of business, including repositioning charges, employee costs, acquisition costs, revenue-related recoveries and certain legal accruals. In addition, the acceleration of deferred compensation of $147 million in 2021 was not allocated to our two lines of business. Prior reported results reflect reclassifications, for comparative purposes, related to management changes in methodologies associated with allocations of revenue and expenses to lines of business in 2022.
