(1)Net revenues of the Pharmacy Services Segment include approximately $1.9 billion and $2.0 billion of retail co-payments for the three months ended September 30, 2013 and 2012, respectively, as well as $6.1 billion and $6.4 billion of retail co-payments for the nine months ended September 30, 2013 and 2012, 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 standalone 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 item (ii) intersegment activity: net revenues of $1.1 billion and $841 million for the three months ended September 30, 2013 and 2012, respectively, and $3.1 billion and $2.5 billion for the nine months ended September 30, 2013 and 2012 respectively; gross profit and operating profit of $143 million and $106 million for the three months ended September 30, 2013 and 2012, respectively, and $409 million and $279 million for the nine months ended September 30, 2013 and 2012, respectively.
