Non-recourse arrangements to discount receivables, as part of discretionary funding in support of certain supply and trading activities and management of credit risk, included $1.7 billion relating to receivables based on provisional prices (2016 $1.3 billion). The group had continuing involvement in these receivables to the extent of movements in market prices after the date of discounting. The amounts which continued to be recognized on the balance sheet relating to the group’s continuing involvement in these receivables totalled $0.2 billion, unchanged from 2016.

Trade and other receivables are predominantly non-interest bearing. See Note 27 for further information.
