(1)Net revenues of the Pharmacy Services Segment include approximately $2.2 billion and $2.0 billion of retail co-payments for the three months ended June 30, 2015 and 2014, respectively, as well as $4.7 billion and $4.2 billion of retail co-payments for the six months ended June 30, 2015 and 2014, respectively.

(2)  Intersegment eliminations relate to two types of transactions: (i) Intersegment revenues that occur when Pharmacy Services Segment customers use Retail Pharmacy Segment stores to purchase covered products. When this occurs, both the Pharmacy Services and Retail Pharmacy segments record the revenue on a stand-alone basis, and (ii) Intersegment revenues, gross profit and operating profit that occur when Pharmacy Services Segment customers, through the Company’s intersegment activities (such as the Maintenance Choice^® program), elect to pick-up their maintenance prescriptions at Retail Pharmacy Segment stores instead of receiving them through the mail. When this occurs, both the Pharmacy Services and Retail Pharmacy segments record the revenue, gross profit and operating profit on a standalone basis. The following amounts are eliminated in consolidation in connection with the intersegment activity described in item (ii) above: net revenues of $1.2 billion for both the three months ended June 30, 2015 and 2014, and $2.4 billion and $2.3 billion for the six months ended June 30, 2015 and 2014, respectively; gross profit of $161 million and $170 million for the three months ended June 30, 2015 and 2014, respectively, and $318 million and $346 million for the six months ended June 30, 2015 and 2014, respectively; and operating profit of $144 million and $170 million for the three months ended June 30, 2015 and 2014, respectively, and $285 million and $346 million for the six months ended June 30, 2015 and 2014, respectively.

(3) The Corporate Segment operating loss includes $21 million of acquisition-related transaction costs for the three and six months ended June 30, 2015.
