Kernrechtsfrage
Whether the 2000 revaluation gain had to be treated as taxable profit and used to offset losses immediately under federal and cantonal tax law.
Extrahierter Entscheid
Yes. The revaluation was profit-effective for tax purposes, so the 2000 loss could be offset immediately; no deductible loss remained for 2001.
Extrahierte Begründung
Art. 58(1)(c) DBG overrides the accounting treatment of a revaluation reserve under Art. 670(1) OR. Losses must be offset with the next available profit without delay, so the loss was already absorbed in 2000.
