All receivables fall into the category “Loans and receivables” and are measured at amortised cost. The total sum of receivables at 31 December 2010 (and 31 December 2009) falls due within one year. Due to their short-term nature, the carrying amounts are assumed to be the fair values. Trade accounts receivables include the following overdue and non-impaired amounts:
|Less than 30 days overdue||11,713||6,967|
|31 – 60 days overdue||8,600||19,176|
|61 – 90 days overdue||6,983||4,727|
|91 – 180 days overdue||13,650||5,324|
|181 – 360 days overdue||16,365||7,929|
|More than 360 days overdue||34,012||32,654|
The total amount of receivables which are neither impaired nor overdue is TCHF 322,632 (previous year: TCHF 309,640). There are no indications that would necessitate an allowance for these receivables.
Allowances for doubtful accounts amounted to:
|At 1 January||12,360||14,845|
|At 31 December||14,845||14,769|
In the case of single significant positions where receipt of payment is uncertain, individual allowances are determined based on internal and external credit rating information. In addition, collective allowances are calculated based on historical accounts receivable losses and current information. Neither collateral nor any other enhancements are available for doubtful receivables.
Disclosure of netting error
In the course of clarifications to correct the error relating to the energy profiles (Note 1), it was found that the conditions for offsetting trade accounts receivables and payable (Note 22) have been fulfilled. As these conditions were already fulfilled last year, the error was corrected in last year's figures.
The offset receivables and payables total CHF 233 million (last year: CHF 141 million).
