Other cash flows from financing activities
In 2015, other cash inflows from financing activities amount to CHF 2 million (prior year: cash outflows of CHF 14 million). This relates mainly to payments in connection with hedging contracts and the commitment fee for the guaranteed credit limit.
Non-cash investing and financing transactions
Additions to property, plant and equipment include additions from finance leases amounting to CHF 9 million (prior year: CHF 13 million). As a result of changes in the assumptions made in estimating the provisions for dismantling and restoration costs, a decrease of CHF 55 million net was recognised in property, plant and equipment (prior year: increase of CHF 157 million).
