Line of Business Information

We have two lines of business: Investment Servicing and Investment Management. Given our services and management organization, 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. Information about our two lines of business, as well as revenues, expenses and capital allocation methodologies with respect to these lines of business, is provided in note 24 to the consolidated financial statements included in our 2012 Form 10-K.

The following is a summary of our line of business results for the periods indicated. The “Other” columns for 2013 and 2012 included net acquisition and restructuring costs. The “Other” column for 2012 also included provisions for litigation exposure. The amounts in the “Other” columns were not allocated to State Street's business lines. Results for the three months ended March 31,2012 reflect reclassifications, for comparative purposes, related to management changes in methodology associated with funds transfer pricing and expense allocation reflected in results for 2013.
