Contract balances with customers

Contract liabilities primarily represent the Company’s obligation to transfer additional goods or services to a customer for which the Company has received consideration, for example the Company’s myWalgreens and Boots Advantage Card loyalty programs. Under such programs, customers earn reward points on purchases for redemption at a later date. See Note 19 Supplemental information, for further information on receivables from contracts with customers.
