Conclusions
The market carries out its assessments differently depending on the standard implemented in its development. We determined the quality of the accounting standard measured through an increment in the evaluative relevance ofthe financial information.In thissense, the reliability in the accounting standards has increased since 2006, year in which the Generally Accepted Principles stopped being used and were adapted to the International Financial Reporting Standards creating the Financial Reporting Standards (FRS). This study offers important contributions for the Mexican market. First of all, foreign and national investors have certain skepticism regarding the transparency of the companies when divulging their accounting information and of the institutions responsible of monitoring the adoption of the accounting regulations (Dorantes, 2013). In this sense, our results show that the coefficients of the fundamental and control variables are significant, furthermore, the two dichotomous variables (FRS and IFRS) are also significant and positive, with the coefficient of the IFRS variable being greater than the coefficient of the FRS. This shows that the changes in the accounting standards have an impact on the quality of the information during the study period of 2000–2013, with the period of the IFRS having the greater relevance than that of the FRS. With these results, some tranquility can be provided to the investors with regard to our institutions and the transparency of our companies.
