Line of Business Information

Line of Business Information

Our operations are organized into two lines of business: Investment Servicing and Investment Management, which are defined based on products and services provided. The results of operations for these lines of business are not necessarily comparable with those of other companies, including companies in the financial services industry. For information about our two lines of business, as well as revenues, expenses and capital allocation methodologies associated with them, refer to pages 188 to 189 in Note 24 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2016 Form 10-K.

The following is a summary of our line-of-business results for the periods indicated. The "Other" column represents costs incurred that are not allocated to a specific line of business, including certain severance and restructuring costs, acquisition costs and certain provisions for legal contingencies.
