The prepayment for certificates of origin and prepaid long-term electricity procurement agreements are amortised on the basis of the physical delivery of electricity and held solely for this purpose. These positions were fully impaired in the amount of TCHF 50,193 in the 2013 financial year. Together with the planned amortisation, this impairment is recognised under energy procurement and concerns the Market Switzerland segment.

The loans granted are allocated to the category loans and receivables and recognised at amortised cost. All other non-current securities are classified as “available for sale” and measured at fair value. This does not affect listed shares or equity securities for which there is no active market and hence for which the fair value cannot be reliably determined. The fair value corresponds to the acquisition value less impairments.

Significant components of other financial assets relate to loans granted to Swissgrid in the 2013 financial year and Swissgrid shares from the sale of Repower Transportnetz AG (Note 26).
