Restructuring Charges

We expect to incur aggregate pre-tax restructuring charges of approximately $300 million to $400 million beginning in 2016 through December 31, 2020 to implement State Street Beacon, our previously announced multi-year transformation program to fully digitize our business to support the development of new solutions and capabilities for our clients and to create cost efficiencies. We estimate those charges will include approximately $250 million to $300 million in severance and benefits costs associated with targeted staff reductions (a substantial portion of which will result in future cash expenditures) and approximately $50 million to $100 million in information technology application rationalization and real estate actions.

In the second quarter and six months ended June 30, 2016, we recorded net restructuring charges of $13 million and $110 million, respectively, due to State Street Beacon.
