Seems LEI clients in the Middle east are in no rush to pay close to $400m in outstanding amounts due for work long completed. 'There has also been a further extension in the anticipated repayment of problem accounts in the Middle East and north Africa, with 59 per cent of the amount due here not expected to be repaid for longer than 2 years, up from 51 per cent six months ago.'
Probably where the expression "bent over a barrel" comes from.
