In 2008, a comprehensive restructuring program was initiated in the segment Austria. The provision for restructuring includes future compensation of employees who will no longer provide services for A1 Telekom Austria Group but who cannot be laid off due to their status as civil servants. These employment contracts are onerous contracts under IAS 37, as the unavoidable cost related to the contractual obligation exceeds the future economic benefit. The restructuring program also includes social plans for employees whose employment will be terminated in a socially responsible way.

Due to their nature as termination benefits, these social plans are accounted for according to IAS 19.
