            (c) Impairment of accounts and bills receivable
          
        
        
          Impairment losses in respect of accounts and bills receivable are recorded using an allowance account unless the
        
        
          Group is satisfied that recovery of the amount is remote, in which case the impairment loss is written off against
        
        
          accounts and bills receivable directly (see note 2(l)(i)).
        
        
          The movement in allowance for doubtful debts during the year, including both specific and collective loss
        
        
          components, is as follows:

          At 31 December 2015, accounts and bills receivable of RMB1,421 million (2014: RMB2,152 million) were individually
        
        
          determined to be impaired. The individually impaired receivables related to customers that were in financial difficulties
        
        
          and management assessed that only a portion of the receivables is expected to be recovered. Consequently, specific
        
        
          impairment losses of RMB511 million (2014: RMB317 million) were recognised. The Group does not hold any
        
        
          collateral over these balances.
