On October 24, 2017, the Company's Board of Directors approved a plan to implement a program (the "Store Optimization Program") to optimize store locations through the planned closure of approximately 600 stores and related assets within the Company's Retail Pharmacy USA segment upon completion of the acquisition of certain stores and related assets from Rite Aid. The Company continues to expect to close approximately 750 stores and related assets, of which substantially all have been closed as part of this program. The actions under the Store Optimization Program commenced in March 2018 and are substantially completed with remaining activities expected to complete by end of fiscal 2020. The Store Optimization Program is expected to result in cost savings of approximately $350 million per year to be fully delivered by the end of fiscal 2020.
