## (a) Allowance for doubtful debts 

Trade receivables are non-interest bearing and are generally on 14 day terms� An allowance for doubtful debts is recognised when there is objective evidence that an individual trade receivable may not be collectible� Based on our assessment of the recoverability of trade receivables at the reporting date, we concluded that an allowance for doubtful debts was not required at 31 March 2013, 31 December 2012 and 31 March 2012�
