Of the £10.8m (2015: £3.8m) bank loans and overdrafts outflows disclosed above, £5.0m (2015: £nil) of bank loans are drawn under the committed facility maturing on 3 July 2019. The overdrafts are on demand and some are part of pooling arrangements, which include offsetting cash balances. Of the £4.3m (2015: £3.8m) derivative financial instruments outflows disclosed above, £4.4m (2015: £3.8m) are matched by derivative cash inflows, therefore the net impact on the balance sheet is £0.1m (2015: £nil).
