g. Trade and other receivables Trade and other receivables are recognized initially at fair value and subsequently measured at amortized cost, less allowance for doubtful accounts. This allowance for doubtful accounts is made based on management’s evaluation of the collectability of outstanding amounts. Accounts are written off in the period during which they are determined to be uncollectible.

h. Inventories

Inventories also include Subscriber Identification Module “SIM” cards, Removable User Identity Module “RUIM” cards, handsets, set top box, wireless broadband modem and prepaid voucher blanks, which are expensed upon sale. Inventories are stated at the lower of cost and net realizable value. Cost is determined using the weighted average method for components, SIM cards, RUIM cards and prepaid voucher blanks, and the specific-identification method for modules. The amount of any write-down of inventories below cost to net realizable value and all losses of inventories shall be recognized as an expense in the period in which the write-down or loss occurs. The amount of any reversal of any write-down of inventories, arising from an increase in net realizable value, shall be recognized as a reduction in the amount of inventories expense in the period in which the reversal occurs. Allowance for obsolescence is primarily based on the estimated forecast of future usage of these items.
