All receivables fall into the category loans and receivables and are measured at amortised cost. The total sum of receivables at 31 December 2015 (and 31 December 2014) falls due within one year. Owing to their short-term nature, the carrying amounts are assumed to be fair values.

Receivables include collateral in the form of deposits lodged by Repower in the context of its business, particularly with respect of its trading operations. These came to TCHF 12,392 (previous year: TCHF 6,427) for the year under review.
