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 Balance Rewards® and Boots Advantage Card loyalty programs. Under such programs, customers earn reward points on purchases for redemption at a later date. See note 18, supplemental information, for further information on receivables from contracts with customers.
