To this end, two theoretical portfolios of the Brazilian market were compared: one composed of ISE (Sustainability Index) companies and the other of Ibovespa companies. The impact of financial performance variables on Abnormal Returns during the Covid-19 pandemic period was analyzed using the Event Study method. This study obtained mixed results. ISE companies obtained higher CAR for the period of the pandemic, demonstrating greater resilience during the crisis. In addition, lower volatility was observed for ESG stocks. The results of the regression models did not identify a positive relationship between profitability indicators and CAR for ISE companies. On the other hand, in line with the hypotheses of this study, there was a positive association between Tobin’s Q of ESG companies and CAR. This research can be useful for academics and investors, as it expands the evidence of ESG investments in terms of financial performance in an emerging market, such as Brazil, and their resilience in times of crisis. Finally, managers, investors, creditors and other professionals may be interested in the results of this research, since ESG investments can develop a competitive advantage, contributing to the long-term success of the business.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"35 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140440342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a basis for the argumentation of this essay, the concepts of assets and their characteristic of generating future economic benefits were incorporated. For the essayist, this characteristic is a beacon for measuring assets and the value of a company, which is made up of a set of tangible and intangible assets. The Discounted Cash Flow is considered one of the main methods for valuing companies. It is essentially financial, derived from the capacity to generate future projected benefits, discounted to present value, adding the value of perpetuity. This method can measure the company in its current situation without the need for growth projections or future macroeconomic factors since case law considers that the future does not belong to the retiring partner. However, the ability to generate these economic benefits cannot be disregarded, which could lead to a valuation that is not fair value, thus harming one of the parties in the dispute. Based on these aspects discussed in the essay, using Discounted Cash Flows in Asset Determination processes is considered pertinent.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140440748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para tal, realizou-se uma pesquisa quantitativa e descritiva com os dados obtidos na base de dados da Economática, que perfez uma amostra com 966 observações, no período de 2010 a 2020. Utilizou-se como medida de habilidade gerencial o modelo de Demerjian et al. (2012), que possui como parâmetros de eficiência as características do gerente na utilização dos recursos para gerar receitas. Para medir a suavização e os níveis de gerenciamento de resultados, utilizaram-se os modelos de Leuz et al. (2003) e McNichols (2002), respectivamente. Os resultados demonstraram que, em média, os gestores mais habilidosos tendem a suavizar e gerenciar resultados em níveis maiores do que gestores com menor habilidade, o que sinaliza que no Brasil, em média, os gestores mais hábeis tendem a diminuir a qualidade do lucro das firmas brasileiras. Este trabalho contribui com a literatura e preenche uma lacuna sobre a habilidade gerencial e o impacto dos resultados das empresas brasileiras, pois evidencia que, no Brasil, a habilidade gerencial está associada com práticas de suavização e gerenciamento de resultados e lança uma luz para as partes interessadas a respeito da influência do perfil dos gestores e suas capacidades de influenciarem nos números divulgados no mercado brasileiro.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"28 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140438507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nesse contexto, esta pesquisa objetivou investigar se existe relação entre as reversões das perdas por impairment evidenciadas pelas empresas brasileiras listadas na B3 e a prática de gerenciamento de resultados entre 2010 e 2019. Para isso, foi realizada uma pesquisa descritiva e quantitativa que testou três hipóteses originalmente desenvolvidas no trabalho de Duh et al. (2009) para analisar se as empresas que mais reconhecem perdas por impairment revertem essas perdas no futuro para evitar a diminuição do resultado contábil e se esse comportamento é mais pronunciado diante de maiores níveis de endividamento ou quando remuneram seus gestores com base no lucro. Os achados revelaram que, embora as empresas que reconheçam mais perdas realizem maiores reversões no futuro, essas reversões não ocorreram em um contexto de declínio do resultado e não foram influenciadas significativamente pelo endividamento e pela sensibilidade da remuneração dos gestores ao lucro. Considerando a escassez de evidências empíricas sobre essa temática no Brasil e a necessidade de se observar esse fenômeno em diferentes ambientes institucionais e regulatórios, espera-se que este trabalho contribua para estimular a realização de outros estudos semelhantes, bem como para fomentar discussões sobre como a possibilidade de reverter as perdas por impairment afeta a qualidade da informação contábil.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139894959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, this research aimed to investigate whether there is a relationship between the reversals of impairment losses evidenced by Brazilian companies listed on B3 and the practice of earnings management between 2010 and 2019. For this, descriptive and quantitative research was conducted, which tested three hypotheses initially developed in the work of Duh et al. (2009) to analyze whether the companies that most recognize impairment losses reverse these losses in the future to avoid the decrease in accounting earnings and whether this behavior is more pronounced in higher levels of indebtedness or when their managers are paid for performance. The findings revealed that, although companies that recognize more losses conduct more significant reversals in the future, these reversals did not occur in the context of declining earnings and were not significantly influenced by indebtedness and the managers’ pay-performance sensitivity. Considering the scarcity of empirical evidence on this topic in Brazil and the need to observe this phenomenon in different institutional and regulatory environments, it is expected that this study will contribute to stimulating the conducting of other similar studies, as well as to foster discussions on how the possibility of reversing impairment losses affects the quality of accounting information.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"199 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139895126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study sample has a total of 560 observations corresponding to 112 companies from 2016 to 2020. The models by specific discretionary accruals of revenues proposed by Caylor (2010) and Stubben (2010) were considered to measure the management levels. As a method of analysis, we used regression models with panel data and tests at a significance level of 5%. According to the results obtained, it was impossible to confirm that adopting CPC 47 (IFRS 15) affected the quality of accounting information from the increase in revenue management levels, as well as whether the effects on the specific sectors indicated by the literature as more impacted were more significant than the other sectors in the Brazilian capital market. The research is relevant because it advances existing studies by using two different revenue management models to analyze the effects of specific accruals after adopting the standard and, in addition, extends the period and sample of Brazilian companies. Therefore, this research contributes to deepening discussions on the effects of applying accounting standards and assists in the analysis of regulatory bodies, preparers, auditors, and financial information on the effects of the new accounting standard after adoption, especially in the Post-Implementation Review (PIR) process of IFRS15.","PeriodicalId":516890,"journal":{"name":"Revista Catarinense da Ciência Contábil","volume":"12 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139893312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
