2.2. Sample
The Spanish firm CABSA provided us with notes to financial statements of 117 listed
Spanish farms. CABSA is a firm that provides analysis and financial data of about
300,000 Spanish firms. We classified the sample in two groups: those disclosing fair
valuation for biological assets in their notes and those disclosing historical cost
valuation. We then selected financial datafrom those farms available in SABI and
CABSA. SABI is a data base of financial statements of about 1,000,000 Spanish and
150,000 Portuguese firms. It covers a larger number of firms than CABSA, but they do
not provide notes to financial statements.
