a. Basis of Presentation
Until December 31, 1995, publicly-traded companies in Brazil
were required to prepare financial statements pursuant to
two methods: (i) the corporate law method, which was and remains
valid for all legal purposes, including the basis for determining
income taxes and the calculation of mandatory minimum dividends;
and (ii) the constant currency method, to present supplementary
price-level adjusted financial statements, pursuant to standards
prescribed by the Brazilian Securities Commission (CVM).
