Risks from collection of mobile phone service fees
The risk of accounts receivable is mainly from post-paid customers who do not pay or make late payment of mobile phone service fees, resulting in the total accounts receivable of the Company in respect of the mobile phone service fees, as at 31 December 2013, of THB 4,007 million. The proportion of the post-paid mobile phone service fees equals to 4.97 per cent of the total income of the Company. However, the Company has set up allowance for doubtful accounts for revenues from post-paid mobile phone service in each aging period on a progressive basis. As at 31 December 2013, the Company’s accounts receivable which had been overdue for a period of more than 180 days were THB 396 million, or 10 per cent of the total accounts receivables from telephone services.
