RESUMO

This project aims at evaluating the used models and proposing the adoption of new models, for the Allowance for Doubtful Accounts, with the objective of measuring the risk related to customers financing and loan activities, and the resulting impact in assets measurements. In order to achieve this goal and try not to over exploit the subject, the following steps related to the development of the theme were adopted. In the introduction the theme is explained; the main issue associated to the theme and the challenges the accounting has to face concerning the assets measurements. As for the risk management the general kinds of risks are described, particularly the credit risk and the credit concession models are evaluated. Referring to the Allowance for Doubtful Accounts constitution, most meaningful authors in the field of Accounting and Finance were researched and similar propositions underlined their writings; that can be summarized in 4 allowance models for Doubtful Accounts. 1. Write off; 2. Percentage over the sales; 3. Percentage over receivables; 4. Aging. Then the correlations between the models of insolvency prediction and the credit losses are analyzed where it is possible to verify that the insolvency models are useful for credit concession, though not very much used for estimating probable loss with Doubtful Accounts. The Central Bank of Brazil (Banco Central do Brasil) issued the act number 2682 on the 21st of December, 1999, that urges all financial institutions to change their methodologies of Allowance for Doubtful Accounts. The Central Bank, however, does not indicate the model to be used, leaving the task of developing the models to each institution. Based on the policy of Central Bank and keeping a scientific approach to the constitution of Allowance for Doubtful Accounts, a model for their constitution in the portfolio is proposed. Such model is tested and evaluated not only, according to the rules of Central Bank of Brazil, but also in terms of management orientation. Having this purpose in mind a statistic model was developed, using LOGIT Regression applied to 202 customers of a financial institution where it was possible to come to the conclusion that the use of the model in the constitution of the Allowance for Doubtful Accounts can bring benefits in measuring the real value of investments in Receivables.
