Bilanzierungs- und Bewertungsgrundsätze

Erworbene immaterielle Anlagewerte wurden zu Anschaffungskosten angesetzt und, sofern sie der Abnutzung unterlagen, um planmäßige Abschreibungen vermindert.

Forderungen und Wertpapiere wurden unter Berücksichtigung aller erkennbaren Risiken bewertet.

Die sonstigen Rückstellungen wurden für alle weiteren ungewissen Verbindlichkeiten gebildet. Dabei wurden alle erkennbaren Risiken berücksichtigt.

Verbindlichkeiten wurden zum Erfüllungsbetrag angesetzt.

Neben den in der Bilanz ausgewiesenen Verbindlichkeiten bestehen keine sonstigen finanzielle Verpflichtungen.
