The foundations for the hypotheses considered in this research were based on: (i) if the companies listed on IBOVESPA that adopted the depreciation rates suggested by the Secretaria da Receita Federal (SRF) had boosted the main accouting performances and (ii) if the companies that adopted the revised depreciation rates under the ICPC 10 had boosted the main accouting performances. The univariate regression model was used empirically to estimate this discretionary Accruals, which are the proxy of changed discretionary value of accounting earnings.
