(b) Impairment of trade debtors
Impairment losses in respect of trade debtors 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 trade debtors directly (see note 1()()).
The movement in the allowance for doubtful debts during the year is as follows:

At 31 December 2018, the Group's trade debtors of HK$2,185,000 (2017: HK$2,151,000) were individually determined to be impaired. The individually impaired receivables related to customers that were in financial difficulties and management assessed that recovery of the receivables is considered doubtful. Consequently, specific allowances for doubtful debts of HK$2,185,000 (2017: HK$2,151,000) were recognised.
