Trade receivables have terms of under one year.

The trade receivables recognised as of 30 September 2009 include receivables of
Euro 8 486 thousand for the settlement of construction contracts in line with their percentage of completion. The advance payments of Euro 10 800 thousand received for these projects have already been accounted for. Revenues of Euro 5 649 thousand were recognised for contract construction in the year under report. Total costs incurred as of the balance sheet date amounted to Euro 17 636 thousand. Construction contracts thus resulted in a loss of Euro 91 thousand.

Write-downs on trade receivables developed as follows:

The calculation of write-down requirements was adapted to the current market situation in the 2008/09 financial year. Since then, receivables have been written down on the basis of manual dunning indicators and their actual age. To account for the declining collectibility of receivables with increasing age, write-down requirements are now determined based on the age of the receivable. For large receivables, this is accompanied by an individual case assessment in order to determine a correct write-down requirement. This adjustment in the calculation of write-downs resulted in additional expenses of Euro 8 704 thousand.

The credit risks and maturity structure of trade receivables were as follows:

There were no indications of write-down requirements for non-impaired trade receivables. All write-downs undertaken were calculated on the basis of individual or group consideration and were not based on general allowances.
