          24,886,623
        
        
          Receivables that were neither past due nor impaired mainly relate to major telecommunications operators for whom
        
        
          there was no recent record of default.
        
        
          Receivables that were past due but not impaired relate to a number of independent customers that have a good
        
        
          track record with the Group. Based on past experience, management believes that no impairment allowances is
        
        
          necessary in respect of these balances as there has not been a significant change in credit quality and the balances
        
        
          are still considered fully recoverable. The Group does not hold any collateral over these balances.

          In respect of construction contacts in progress at the end of the reporting period, the amounts of retentions held by
        
        
          customers for contract work, recorded within “Accounts and bills receivable, net” at 31 December 2015 are RMB41 million
        
        
          (2014: RMB26 million).
