Paragraphs:
9.4. Trade and other payables
Trade payables are unsecured and are usually paid within 30 days of recognition. Other payables and accruals are paid when amounts fall due. The carrying amounts of trade and other payables are assumed to be the same as their fair values, due to their short-term nature.
