Soweit im Berichtsjahr hinsichtlich der im Vorjahr von den Gliederungsvorschriften des HGB und des GmbHG abweichenden Positionen der Bilanz- und Gewinn- und Verlustrechnung Veränderungen vorgenommen wurden, wurde dem Prinzip der Darstellungsstetigkeit (§ 265 Abs. 1 HGB) durch Anpassung der Vorjahreszahlen entsprochen.

Das Sachanlagevermögen wird zu Anschaffungs- oder Herstellungskosten vermindert um die steuerlich zulässigen Abschreibungen angesetzt.

Geringwertige Wirtschaftsgüter werden gemäß § 6 Absatz 2 EStG im Jahr des Zugangs voll abgeschrieben.

Forderungen aus Lieferungen und Leistungen sowie sonstige Vermögensgegenstände werden zum Nennwert vermindert um Wertberichtigungen und unter Beachtung des Niederstwertprinzips angesetzt.

Bei der Bemessung der Rückstellungen wurden allen erkennbaren Risiken angemessen und ausreichend Rechnung getragen.

Verbindlichkeiten wurden zum Rückzahlungsbetrag angesetzt.
