Summary Of Line Of Business Results

The following is a summary of our line of business results for the periods indicated. The “Other” columns for 2012 included the net realized loss from the sale of all of our Greek investment securities; acquisition-related integration costs; restructuring charges associated with our business operations and information technology transformation program and expense control measures; and litigation settlement costs. The "Other" columns for 2011 included acquisition-related integration costs and restructuring charges associated with our business operations and information technology transformation program. The amounts in the “Other” columns were not allocated to State Street's business lines. Results for the 2011 periods reflect the retroactive effect of management changes in methodology related to funds transfer pricing and expense allocation in 2012.
