During the second quarter of 2017, Shire entered its second phase of integration activities.

For further details on existing agreements with Baxter, refer to Note 28, Agreements and Transactions with Baxter, of Shire's 2016 Form 10-K. The Company also plans to drive savings through the continued prioritization of its research and development programs and continued consolidation of its commercial operations. The integration of Baxalta is estimated to be completed by mid to late 2019.

The Baxalta integration and acquisition costs include $80.2 million and $117.1 million, respectively, of employee severance and acceleration of stock compensation, $50.4 million and $85.6 million, respectively, of third-party professional fees and $17.2 million and $41.7 million, respectively, of expenses associated with facility consolidations for the three and six months ended June 30, 2017.
