The aim of my diploma thesis was the application of the selected method of identifying accounting fraud in setting of chosen company. In the first part of this work were used methods based on the comparison of data chosen company with the data of competitive companies in the same industry or with the data of industry. I compare the return on equity (ROE), return on assets (ROA), Daily income and balance of accounts receivable, profit margin. In the next part of this work were used special methods to identify accounting fraud. I used methods Beneish M-score model, cash realization ratio, Jones nondiscretionary accruals. As an additional analysis, I used the bankruptcy Altman Z-score model. In conclusion, I compared the risks identified possible manipulation of financial statements for all tests and analyzes. All performed tests and analyzes in aggregate have identified this risk as low. Yet some of them pointed to further more detailed research in revenues, margins and setting transfer prices.

Mais especificamente, o objetivo do presente estudo é verificar se as empresas financiadas por fundos de PE/VC estréiam no mercado acionário brasileiro com melhor qualidade de informação contábil e melhores padrões de governança corporativa do que as restantes. A amostra utilizada é composta por 69 empresas que efetuaram oferta pública inicial (IPO) na Bolsa de Valores de São Paulo (BOVESPA) no período de janeiro de 2004 a julho de 2007. Primeiramente, constatou-se que o nível de gerenciamento de resultados contábeis, ou earnings management (medido pelas acumulações discricionárias correntes) das companhias com investimento de PE/VC é significativamente inferior ao nível apresentado pelas empresas que não receberam este tipo de aporte de capital. Ademais, os resultados indicam que a influência do gestor de PE/VC na redução da manipulação de informações contábeis é mais importante exatamente no momento mais crítico, ou seja, no intervalo imediatamente ao redor da data do IPO, quando as empresas gerenciam os resultados mais intensamente. Por fim, também foram encontradas evidências de que as empresas investidas por PE/VC possuem conselhos de administração mais independentes da gestão, em comparação às demais empresas da amostra. A proporção de membros executivos e instrumentais, estreitamente relacionados à administração, é menor entre o grupo de companhias do portfolio dos fundos de PE/VC, enquanto a participação relativa de conselheiros com a função de monitoramento é substancialmente maior. Os resultados obtidos no presente estudo foram robustos a diversos testes de sensibilidade. Em síntese, as evidências encontradas levam à conclusão de que as organizações de private equity e venture capital influenciam de forma positiva as práticas de governança corporativa das empresas por elas financiadas. / This paper investigates the role of private equity and venture capital (PE/VC) organizations in the corporate governance of portfolio firms. More specifically, the objective of the present study is to verify if the PE/VC-backed companies have better financial reporting quality and corporate governance standards than others at the time of the Initial Public Offering (IPO) in Brazil. The sample is composed of 69 firms’ IPOs on the Bolsa de Valores de São Paulo (BOVESPA) in the period from January 2004 to July 2007. First, it was verified that PE/VCbacked companies have significantly lower earnings management (measured by the level of discretionary current accruals) than non-PE/VC-backed firms. Moreover, the results indicate that the influence of PE/VC managers in reducing the manipulation of accounting information is more important exactly in the most critical moment, that is, in the interval immediately around the date of the IPO, when firms manage earnings upwards more intensely. Finally, evidences have showed, as well, that PE/VC invested companies have boards of directors more independent from management, compared to other companies in the sample. The proportion of executive and instrumental members in the board, closely related to the management, is lower among the group of companies in the portfolio of PE/VC funds, while the participation of directors with the task of monitoring is substantially greater. The results obtained in this study were robust to different tests of sensitivity. In summary, the evidences found lead to the conclusion that private equity and venture capital organizations influence in a positive way the practices of corporate governance at companies they finance.

A sample of non-financial Brazilian companies (361 firms) was used. Data were collected at the website of the CVM or at the website of the companies, when necessary. To measure earnings management through discretionary accruals Jones Model and KS Model were applied, including the internationally used variations of these models and the use of polynomial equations. A model developed in this study was used to observe the effect of IFRS on earnings management of firms in periods Full- IFRS and Hybrid, and the restrictive effects of Big Four audit, corporate governance and regulatory environment. The results of earnings management were considered through discretionary accruals obtained by residues of the models that had better information as statistical results: Model Jones polynomial; Modified Jones Model by Kothari, Leone and Wasley (2005) original polynomial and omitting accounts receivable; Modified Jones Model by Teoh, Welch and Wong (1998) with the omission of the polynomial variation of accounts receivable and inclusion of ROA; and Model KS polynomial. Evidence was found that convergence to IFRS had a restrictive effect on earnings management in Brazil after the complete implementation of IFRS. Among the factors constraining earnings management studied by Big Four audit, corporate governance and regulatory environment, it was noted that the most effective is the regulatory environment. Entities, whose industry is regulated by a regulatory agency in addition to the CVM, have lower levels of earnings management than the others. It was also noted that the larger the company the lower is the level of earnings management. It is noteworthy that the process of convergence to IFRS in Brazil is recent, this way, this work was limited to short coverage periods of these standards. Given this limitation, it is suggested that more research would be conducted to examine earnings management in IFRS in Brazil in later periods, to validate the results obtained by this work, maintaining the reduced use of discretionary appropriations in light of IFRS in Brazil. / O objetivo geral deste trabalho foi avaliar se as mudanças nas práticas contábeis trouxeram redução no gerenciamento de resultados das empresas abertas brasileiras não financeiras, ocasionando uma melhoria na qualidade da informação contábil. Foi utilizada uma amostra composta por companhias abertas brasileiras não financeiras (361 empresas). Os dados foram coletados no sítio da CVM ou no sítio das próprias empresas, quando necessário. Para mensurar o gerenciamento de resultados por meio de apropriações discricionárias foram aplicados os Modelos Jones e KS, incluindo as variações internacionalmente utilizadas destes modelos e com uso de equações polinomiais. Foi utilizada uma modelagem desenvolvida neste trabalho para observar o efeito das IFRS no gerenciamento de resultados das empresas, nos períodos Full-IFRS e Híbrido, e dos efeitos restritivos de auditoria por Big Four, governança corporativa e ambiente regulatório. Foram considerados como apropriações discricionárias, os resíduos dos modelos de gerenciamento de resultados que apresentaram melhores informações conforme resultados estatísticos: Modelo Jones polinomial; Modelo Jones Modificado por Kothari, Leone e Wasley (2005) polinomial original e com omissão de contas a receber; Modelo Jones Modificado por Teoh, Welch e Wong (1998) polinomial com omissão da variação de contas a receber e com inclusão do ROA; e Modelo KS polinomial. Foram encontradas evidências de que a convergência às IFRS teve efeito restritivo no gerenciamento de resultados no Brasil após a implantação completa das IFRS. Entre os fatores restritivos ao gerenciamento de resultados estudados, auditoria por Big Four, governança corporativa e ambiente regulatório, notou-se que o mais efetivo é o ambiente regulatório. As entidades cujo setor é regulado por uma agência regulatória além da CVM, apresentam menores níveis de gerenciamento de resultados que as demais. Notou-se também que quanto maior a empresa menor o nível de gerenciamento de resultados. Ressalta-se que o processo de convergência às IFRS no Brasil ainda é recente, desta forma, este trabalho foi limitado ao curto período de vigência destas normas. Considerando-se esta limitação, sugere-se que sejam efetuadas mais pesquisas para analisar o gerenciamento de resultados na Era IFRS no Brasil em períodos posteriores, para validação dos resultados obtidos por este trabalho, com manutenção da redução do uso de apropriações discricionárias à luz das IFRS no Brasil.

Consistente com a literatura, o porte de auditoria tem sido utilizado como proxy de qualidade do serviço, e classificado como auditoria Big 6 e não-Big 6, sendo quanto maior o porte, maior a qualidade. A pesquisa abrangeu os estudos que utilizam acumulações discricionárias na estimação da manipulação da informação contábil. Por meio de uma revisão sistemática da literária, foram selecionadas 14 pesquisas empíricas, abrangendo Estados Unidos, Europa e Ásia. Com base na análise dos seus aspectos substantivos e metodológicos, a conclusão é que a magnitude da manipulação da informação contábil não é uniforme nos países estudados sugerindo que os ambientes cultural, institucional e legal podem influenciar a capacidade da auditoria em mitigar a ação discricionária dos gestores. / This study examines the relation between the audit firm size and the manipulation of accounting information. Consistent with the literature, firm size has been used as a proxy for quality of service, and classified as Big 6 and non-Big 6, and the larger the size, the better the quality. The survey covered the studies that use discretionary accruals in the estimation of earnings management Through a systematic review of literature, 14 empirical researches were selected, covering the United States, Europe and Asia. Based on the analysis of their substantive and methodological issues, the conclusion is that the magnitude of the accounting manipulation of information is not uniform in the countries surveyed suggesting that the cultural, institutional and legal environments may influence the ability of the audit to mitigate managers’ discretion.

Cette thèse se compose de trois essais sur deux anomalies bien documentées : effet momentum et anomalie des ajustements comptables. Le premier essai examine si l'ampleur de l'anomalie des ajustements comptables est entraînée par la probabilité de détresse financière. Les résultats indiquent que l'anomalie des ajustements comptables est économiquement et statistiquement positive pour les entreprises avec une faible probabilité de détresse financière, mais non significative pour celles avec une forte probabilité de détresse financière. Cela signifie que cette anomalie des ajustements comptables est omniprésente, mais pas limitée aux entreprises avec une faible probabilité de détresse financière. Le deuxième essai étend la question de recherche abordée dans le premier essai au marché boursier émergent du Vietnam. Comme pour les résultats du premier essai, les résultats indiquent que l'anomalie des ajustements comptables est limitée aux stocks avec une faible probabilité de détresse financière. Le dernier essai examine si l'effet momentum se produit sur le marché boursier vietnamien. Les résultats confirment la présence de momentum dans le court terme et révèlent aussi que les rendements gagnants et perdants sont faiblement persistants, mais que la forte corrélation entre ces rendements gagnants et perdants crée des bénéfices momentum significatifs. / This dissertation consists of three essays on two well-documented anomalies: momentum effect and accrual anomaly. The first essay investigates whether the magnitude of accrual anomaly is driven by the financial distress probability. The results indicate that accrual anomaly is economically and statistically positive for firms with low financial distress probability, but insignificant for those with high financial distress probability. This means that that accrual anomaly is not pervasive but limited to firms with low financial distress probability. The second essay extends the research question addressed in the first essay into the emerging stock market of Vietnam. Similar to the findings in the first essay, the results indicate that the accrual anomaly is limited to the stocks with low financial distress probability. The last essay examines whether the momentum effect occurs in the Vietnamese stock market. The results support the occurrence of momentum in the short-run and also reveal that winner and loser returns are low persistent, but the strong correlation between winner and loser returns creates significant momentum profits.

The topic of this thesis is issue of profit or loss in a company. First, we discuss a theoretical ways of defining and measuring profit or loss. In addition, attention will focus on the profit and loss statement and analysis of some of its items. Part of the thesis also deals with the taxation and profit distribution in the various business entities. In conclusion, the thesis analyzes profit or loss in a particular company.

The diploma thesis focuses on comparison of selected economic phenomenon in various accounting systems. Examined systems are IFRS, US GAAP and Czech accounting legislation. Thesis examines long-lived assets (Property, Plant and Equipment), leasing and accruals. It contains a comparison of reporting rules of these accounting areas and the assessment of impacts caused by the different approaches of the examined systems.

Sloan（1996）研究指出，投資人無法完全地分辨出應計項目與現金流量間盈餘持續性的差別，導致對應計項目資訊反應過度，而對現金流量資訊則反應不足，因此公司擁有相對較高（低）的應計項目使用金額，預期會有負（正）的未來股票異常報酬率，此種存在於應計項目與未來來股票異常報酬率間之負向關係，即本文所稱之「應計項目異常現象」。 投資人方面，本研究依資訊取得優勢，區分為內部關係人、機構投資人（外資、投信、自營商）與自然人；投資人持股行為則分別以持股比例與持股比例變動代表。此外，並將應計項目分別以總應計項目與總應計項目組成要素下之個別營運資金應計項目（應收帳款變動數、存貨變動數與應付帳款變動數）作衡量。首先測試應計項目異常現象是否存在於我國，再利用應計項目異常現象建構之套利投資組合，買進最低應計項目金額的投資組合而賣出最高應計項目金額的投資組合，探討應計項目異常現象與投資人持股行為之關聯性。 實證結果顯示，應計項目異常現象存在於我國，亦存在於個別營運資金應計項目。持股比例方面，外資與內部關係人似乎能利用應計項目異常現象形成之套利投資組合；當總應計項目的金額愈低，持股比例會愈高，但在不同應計項目的衡量方法下會有不同的結果。持股比例變動方面，除內部關係人與自然人稍佳之外，本研究設計之迴歸模型並無對應計項目與投資人持股比例變動間之關聯性有足夠的解釋能力。此外，第二年度的內部關係人持股比例變動雖與總應計項目、存貨變動數有負向的關聯性，惟統計結果並不顯著。 關鍵字：應計項目異常現象、投資人、持股行為、應計項目、機構投資人、內 部關係人、自然人、套利投資組合 / Sloan（1996）results indicate investors failing to distinguish fully between the different properties of the accrual and cash flow components of earnings. This leads to overreaction of the information contained in the accrual components of earnings and underreaction of the cash flow components of earnings.Consequently,firms with relatively high (low) levels of accruals experience negative (positive) future abnormal stock returns. The negative relationship between accounting accruals and subsequent stock returns calls the “Accruals anomaly” in this paper. With repect to the investors, I distinguish them from the advantage of obtaining the information into insiders, institution investors (QFII, mutual funds, security dealers), and individual investors; then use the percentage of the investors’ holding and the percentage of the investors’ holding change to represent the investors’ holding behavior. Besides, I use the total accruals and individual working capital accruals（change in accounts receive, change in inventory, and change in minus accounts payable）to measure accruals. Firstly, I test whether the accruals anomaly exists in our country or not, then exploit the hedge portfolio formed by accruals anomaly,by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals generates positive abnormal stock returns to probe into the association between accruals anomaly and investors’ holding behavior. The results suggested that accruals anomaly indeed exists in our country and the individual working capital accruals. With regard to the percentage of the investors holding, QFII and insiders seems to capable of exploiting the hedge portfolio formed by accruals anomaly; when firms with relatively low levels of total accruals experience the percentage of the high investors holding,but there have different results of using dissimilar measurement of accruals. For the percentage of the investors holding change, this paper’s regression model doesn’t have enough capability of explaining the association between accruals and percentage of the investors holding change except insiders and individual investors. Furthermore, although the percentage of the insiders’ holding change in the second year is negatively correlated with total accruals and change in inventory, the empirical results are not significant. Key words: accrual anomaly, investors, holding behavior, accruals, institution investors, insiders, individual investors, hedge portfolio

Three main issues are investigated: the type of operation (LBO or Acquisition), the periods in which occur significant manipulation and the legislation change in 2001, which main goal was to cohibit the abusive rebuying of shares by the companies that wanted to go private prior to the going-private operation. The sample is composed of 132 companies that went private from 1999 to 2009 and the data were quarterly collected ranging five years. We found evidence that the sample firms manipulated their earnings approximately two years before going private. Also, some results show that there are differences in the direction of earnings management depending on the type of public-to-private operation: LBOs firms tended to manage their earnings up, as well as the companies that were acquired by their controlling firms, while the other acquisitions showed signs of downward manipulations. Finally, we found evidence that the legislation change in 2001 not only might have changed the pattern of firm´s manipulation but has also increased earnings management right after its effective date. / Esse trabalho investiga a dinâmica da manipulação de resultados de empresas brasileiras que fecharam o capital no período de 1999 a 2009. Dentre os fatores investigados estão o tipo de fechamento (OPA, aquisição, aquisição por controladoras), o período de manipulação e a mudança que a Lei nº 10.303/2001 (cujo objetivo era coibir o fechamento branco de capital) teria sobre o gerenciamento. A amostra utilizada é composta de 132 empresas que realizaram o fechamento no período citado, sendo o ciclo de dados coletado para cada empresa de vinte trimestres. Foram achados indícios de que essas empresas manipularam seus ganhos aproximadamente dois anos antes de seu fechamento. Além disso, foram encontradas evidências de diferença de direção de manipulação para os tipos de fechamento: empresas cujos fechamentos ocorreram através de OPA, assim como as que sofreram aquisição por suas controladoras, tenderiam a manipular seus ganhos para baixo, enquanto que as demais aquisições se caracterizariam por terem seus resultados adulterados para cima. Por fim, foram achados indícios de que a Lei nº 10.303/2001 tenha alterado o comportamento de manipulação contábil das empresas e de que houve um aumento de manipulação logo em seguida à sua vigência.
