The main purpose of this study is to determine the impact of questionable governance practices on Agrenco´s management, listed under BDR program, over the returns of other companies with the same structure. Previous papers were about to determine the factors that influence firms in their decision to list their stocks in different stock exchanges. This one is related to the impact on the returns of a bankruptcy event on a company listed under BDR structure over other companies with the same characteristics. Understand the consequences of Agrenco´s event is mandatory to financial markets players. Two methods of analysis were applied in this study. The fist approach was referred to a simple graphical observation of asset prices listed under BDR programs. The second, used econometric models to understand if Agrenco´s event resulted in negative returns to companies listed under BDRs structures. A time series model was applied (AR approach of auto-regression) by using structural break dummy variable. Both of them were intended to verify that from the date of the bankruptcy of Agrenco, the companies listed in the form of BDRs were negatively affected by their prices as a result of such event. The results, based on the charts, not indicated a detachment of the most of share´s return from the Ibovespa index one week after the announcement of the financial problems of Agrenco. The second, based on econometric tests, indicated that there was Agrenco´s impact on the returns of stocks listed in the form of BDR. The major contribution of this study was to verify that the event of bankruptcy on Agrenco contaminated the return of other companies listed under the same vehicle as a source of funding.
