This fact is occurring also in Brazil, mainly due to the world changes that have been causing the competition increasing. This importance is due to not only the transaction quantities but mostly because many times the values involved are extremely high. It is not possible to say it is only a business concentration phenomenon: there are several reasons for the realization of these transactions, with a crescent utilization to reduce effectively the tributary charge assessed to the companies. In Brazil, the utilization of these operations started due to some tax advantages offered by the Federal Government. In 1971, it was created the Comiss?o de Fus?o e Incorporac?o de Empresas - COFIE, a commission connected to Ministry of Finance, in order to coordinate and analyze these tax advantages. The merger transactions were regulated for a long time past, but the spin-off transaction was inserted in the Brazilian legislation only in 1976, through the federal Law nr. 6404/76, known as Lei das S/A - the corporation acts. With this legal regulation, the utilization of the business company combinations has increased in spite of the Brazilian concept differences in relation to the United States of America and Europe ones. It is the case, for instance, of the merger, that they consider as a special type of consolidation. The professionals that work in tributary planning, that is, attorneys, accountants, managers and economists, amplified the business company combination use in Brazil, mainly merger and spin-off, due to the tax advantages reached through the Income Tax reduction, elimination or postponement, for several reasons. The main point of this study is the accounting and tributary ones to show the employment of these operations to substitute the acquisitions, aiming mainly the elimination of the capital gain of the stockholders, being an individual person or a company. The objective of this study was confirmed by the searches: this way of using the business company combination causes problems in the areas of law and accountancy, because in Brazil people are more connected to the juridical way of the fact than the economic one. So it may be concluded that the accountancy and the law professionals have many things to search and develop to improve and differentiate the types of transactions - those involving companies that have the same corporate control and those involving companies pertaining to different economic groups, explaining also the method differences used in the accountancy registers. / As reorganiza????es societ??rias atrav??s dos institutos da fus??o, incorpora????o e cis??o v??m tendo sua participa????o e import??ncia ampliadas no cen??rio atual da economia mundial, inclusive no Brasil, principalmente devido ?? globaliza????o e ao crescimento da concorr??ncia. Essa import??ncia deve-se n??o apenas ao quantitativo de opera????es, mas tamb??m ao fato de que os valores envolvidos muitas vezes s??o bem elevados. Tamb??m n??o se pode afirmar que ?? apenas um fen??meno de concentra????o empresarial: h?? in??meras e variadas raz??es para a efetiva????o dessas opera????es, com sua crescente utiliza????o como forma de redu????o do ??nus tribut??rio aplicado ??s empresas. No Brasil, o emprego dessas opera????es foi implementado utilizando-se alguns benef??cios fiscais concedidos pelo Governo Federal; criou-se em 1971 a Comiss??o de Fus??o e Incorpora????o de Empresas - COFIE, ligada ao Minist??rio da Fazenda, com a finalidade de coordenar e analisar a concess??o desses benef??cios fiscais. A fus??o e a incorpora????o j?? eram devidamente regulamentadas h?? um bom tempo, mas a cis??o somente foi introduzida na legisla????o brasileira atrav??s da Lei das Sociedades An??nimas, em 1976. Com isso, ampliou-se a utiliza????o de tais institutos, apesar de em nossa legisla????o societ??ria e fiscal haver algumas diferen??as conceituais em rela????o aos Estados Unidos e Europa: ?? o caso da incorpora????o, que l?? ?? considerada como um tipo especial de fus??o. Os profissionais que operam com planejamento tribut??rio, sejam advogados, contadores, administradores e economistas, ampliaram o emprego principalmente da incorpora????o e cis??o no Brasil devido ??s vantagens fiscais alcan??adas atrav??s da redu????o, elimina????o ou posterga????o de Imposto de Renda, por diversas raz??es. O foco principal deste estudo compreende as ??reas cont??bil e tribut??ria, com o fim de demonstrar o emprego dessas opera????es em substitui????o ??s de aquisi????o, visando principalmente a elimina????o do ganho de capital dos acionistas ou quotistas, sejam pessoas f??sicas ou jur??dicas. Conforme era o objetivo do estudo, pelas pesquisas desenvolvidas confirmou-se tal utiliza????o, provocando essa forma de emprego distor????es tanto no campo jur??dico como nos procedimentos cont??beis adotados, vez que no Brasil preocupa-se mais com a forma jur??dica do que com a econ??mica dos fatos. Isso leva a concluir que tanto os profissionais da contabilidade como os do direito t??m muito a pesquisar e desenvolver para aperfei??oar e distinguir essas opera????es, tanto as ocorridas entre empresas sob o mesmo controle societ??rio quanto entre as pertencentes a grupos econ??micos distintos, clarificando inclusive as diferencia????es dos m??todos adotados nos registros cont??beis.

There are some situations in which the interest zones are depleted or have low fracture pressure. In such cases, the adoption of lowdensity cement slurries is an efficient solution. To this end, there are basically three ways to reduce the density of cement slurries: using microspheres, water extending additives or foamed cement. The objective of this study is to formulate, to study and to characterize lowdensity foamed cement, using an air entrainment surfactant with vermiculite or diatomite as water extenders and stabilizers. The methodology consists on preparation and evaluation of the slurries under the American Petroleum Institute (API) and the Brazilian Association of Technical Standards (ABNT) guidelines. Based on calculated densities between 13 and 15 ppg (1.559 and 1.799 g/cm3), the slurries were prepared with fixed surfactant concentration, varying the concentrations of vermiculite and diatomite and were compared with the base slurries. The results of plastic viscosity, yield point and gel strength and the compressive strength for 24 h showed that the slurries presented suitable rheology and mechanical strength for cementing operations in oil wells, and had their densities reduced between 8.40 and 11.89 ppg (1.007 and 1.426 g/cm3). The conclusion is that is possible, under atmospheric conditions, to obtain light weighted foamed cement slurries with satisfactory rheological and mechanical properties by means of air entrainment and mineral additions with extenders and stabilizers effects. The slurries have great potential for cementing operations; applicability in deep wells, in low fracture gradient formations and in depleted zones and bring cost savings by reducing the cementing consumption / As opera??es de cimenta??o podem ocorrer em diversas etapas do ciclo de vida de um po?o, desde a sua constru??o at? seu abandono definitivo. H? situa??es em que as zonas de interesse se apresentam depletadas ou com baixa press?o de fratura. Nesses casos, a ado??o de pastas cimentantes de baixa densidade constitui solu??o eficiente. Para tanto, h? basicamente tr?s maneiras de reduzir a densidade de pastas de cimento: usando microesferas, aditivos estendedores de ?gua ou pastas espumadas. O objetivo deste trabalho ? formular, estudar e caracterizar pastas cimentantes espumadas de baixa densidade, utilizando um surfactante incorporador de ar juntamente com adi??es de vermiculita ou diatomita como estendedores e estabilizantes. A metodologia do trabalho consiste na prepara??o e avalia??o das pastas por meio de procedimentos adotados pelo American Petroleum Institute (API) e pela Associa??o Brasileira de Normas T?cnicas (ABNT). Partindo de densidades calculadas entre 13 e 15 lb/gal (1,559 e 1,799 g/cm3), as pastas foram preparadas com dosagem fixa do surfactante, variando as concentra??es de vermiculita e diatomita e foram comparadas com pastas base. Os resultados dos ensaios que determinam viscosidade pl?stica, limite de escoamento e for?as g?is, bem como os de resist?ncia ? compress?o para tempos de 24 h mostraram que as pastas apresentaram reologia e resist?ncia mec?nica adequadas para opera??es de cimenta??o em po?os de petr?leo, al?m de terem suas densidades reduzidas entre 8,40 e 11,89 lb/gal (1,007 e 1,426 g/cm3). Conclui-se que ? poss?vel, sob condi??es atmosf?ricas, obter pastas cimentantes espumadas de baixa densidade com propriedades reol?gicas e mec?nicas satisfat?rias, por meio de incorpora??o de ar e adi??es minerais com efeitos estendedores e estabilizantes. As pastas possuem grande potencial para opera??es de cimenta??o, t?m aplicabilidade em po?os profundos, forma??es de baixo gradiente de fratura e zonas depletadas e trazem redu??es de custo pela diminui??o do consumo de cimento

It was the result of an investigation under a qualitative approach, while the data were analyzed in addition to the quantifiable dimensions, but a universe embraced by signs, senses and meanings attributed to the object in focus. The empirical universe of the study was two hospital equipments linked to the Department of Health of the State of Bahia, administered under different legal and administrative systems. The choice of these hospitals met the criteria: broad flow demand of massive technological development and that were allocated near the university in which the study is linked. Empirical research showed with the application of semi-structured interviews scripts together professionals from both units. Discussions necessary researches are categorized in the debate on hospital care, specifying on its structure and the adjacent and constituent subjects in defendants processes. The results of this study reflect issues to the very interface between humanization and technological resources in health, converging on the antagonistic character attributed to technology, now seen as making it humanizes, sometimes as dehumanizing mechanism. Also, the data also indicate on the various meanings attributed to humanization, converging with its polysemous attribute. Although, all the undertaken theoretical basis points directives that establish with the ideal of restructuring hospital care, with a focus to their practice. With regard, it urges the need to safeguard the qualities inherent in the principle of ethics, as they stand up for human values in much needed. Therefore, the discussions related to the paradigm of execution of humanization in the health field by the driver of technological resources, are recurrent. Thus, it points out the need to build care environments conducive to the introduction of targeted practices and demarcated by the complementarity between categories humanization and technology. Therefore, the need to adopt and reflect on an integrative approach is argued between them, facilitating the humans values to scale on the technologic practices, proceduralists, as combated. / A pesquisa tem como objetivo analisar a interface entre a humaniza??o e a incorpora??o tecnol?gica em unidades hospitalares. Foi fruto de uma investiga??o com abordagem qualitativa, ao passo que os dados foram analisados al?m das dimens?es quantific?veis, mas num universo abarcado por signos, sentidos e significados atribu?dos ao objeto em foco. O universo emp?rico do estudo foi dois equipamentos hospitalares vinculados ? Secretaria Estadual de Sa?de do Estado da Bahia, administrados sob diferentes regimes jur?dico-administrativos. A escolha desses hospitais se deu devido aos seus amplos fluxos demandat?rios, ? maci?a incorpora??o tecnol?gica em ambos e ao fato de estarem alocados pr?ximos ? universidade em que esse estudo est? vinculado. A pesquisa emp?rica evidenciou-se com a aplica??o de roteiros semiestruturados de entrevistas junto aos profissionais de ambas as unidades. As discuss?es necess?rias ? pesquisa categorizam-se no debate sobre o cuidado hospitalar, especificando sua estrutura e os sujeitos adjacentes e constituintes nos processos demandados. Os resultados desse estudo refletem quest?es referentes ? pr?pria interface entre a humaniza??o e a incorpora??o tecnol?gica em sa?de, convergindo quanto ao car?ter antag?nico atribu?do ? tecnologia, ora vista como fazer que humaniza, ora como mecanismo desumanizador. Igualmente, os dados indicam os v?rios sentidos atribu?dos ? humaniza??o, confluindo com seu atributo poliss?mico. Conquanto, todo o aporte te?rico empreendido aponta diretivas que coligem com o ideal de reestruturar o cuidado hospitalar, com enfoque ao campo das pr?ticas. A pesquisa incita a necessidade de resguardar as qualidades inerentes ao princ?pio da ?tica, ? medida que ressalta os valores humanos, em muito carecidos. Logo, as discuss?es relacionadas ao paradigma da efetiva??o da humaniza??o no campo da sa?de, mediante o fator condicionante da incorpora??o tecnol?gica, s?o recorrentes. Assim, aponta-se para a necessidade de se construir ambientes de cuidado prop?cios ? instaura??o de pr?ticas direcionadas e demarcadas pela complementariedade entre as categorias ?humaniza??o? e ?tecnologia?. Portanto, defendeu-se a necessidade de adotar e refletir acerca de uma abordagem integradora entre ambas, possibilitando aos valores humanos dimensionarem-se sobre as pr?ticas tecnicistas, em geral, muito combatidas.

In Brazil a major increase in the volume of business combination transactions has been observed in recent years. The publication of Law n?? 11.638/07 has served to afford conditions for Brazil to move in the direction of convergence with international standards, making the adoption of these standards, including those concerning business combination transactions, mandatory. The aim of this study is to: (i) verify whether there are significant differences between the goodwill recognized and measured before and after the adoption of IFRS for business combination transactions, by non-financial companies, listed in Spain and in the United Kingdom; and (ii) analyze the alterations of the accounting treatment prescribed by Brazilian standards with the taking effect of Law n?? 11.638/07, and to prospect probable barriers in the adoption of IFRS in Brazil, for business combination transactions. The study considers and relates the origin of the countries studied (Continental Europe x Anglo-Saxon Europe), as well as the basis of the accounting standards (rules x principles) to the differences identified in response to the adoption of IFRS. The research hypotheses were developed based on the review of literature, expecting to identify: significant alterations in the amount of goodwill recorded; more significant differences at companies listed in countries with their origin in Continental Europe; and differentiated perceptions of the impacts resulting from the adoption of IFRS by companies from different segments. To attain the objective a survey was conducted with a basis on the financial statements of 63 companies, with 35 listed in Spain and 28 in the United Kingdom, analyzing the impacts that occurred during the first year of adoption of IFRS. Statistical techniques were applied for analysis of the differences perceived with the adoption of IFRS and testing of the hypotheses defined, using: (i) Wilcoxon test aiming to evaluate the effects of the application of IFRS at the same company; (ii) Mann-Whitney test to compare the variation between the two listing countries, and; (iii) Kruskal-Wallis test for comparison among the various segments of the sample. The results obtained in the tests, besides other aspects, confirmed the existence of a significant difference in the goodwill before and after IFRS in the countries from the sample, Spain and the United Kingdom. These results and the analysis of previous studies made it possible to prospect probable barriers in the IFRS adoption process for business combination transactions at Brazilian companies. / Opera????es de combina????o de neg??cios representam uma estrat??gia de crescimento para muitas companhias ao redor do mundo.

Thus, the objective of this research was to investigate whether the M&A events occurred between years 2000 and 2010 in companies listed on the BM&FBOVESPA created shareholder value. Variables Tobin's Q and the EVA?? were used as proxies for value creation. Data of 83 transactions M&A were analyzed in 28 purchasing companies or resulting companies, seeking to observe the behavior of the variables after the announcement of the transaction within 36 months and for the remainder of the period (ten years) where there was data availability. Also, the data allowed comparison between results of the sample's averages and the averages of others companies listed on the BM&FBOVESPA non-sampled. The results showed symmetry with those of most previous studies demonstrating that M&A did not affect the creation of value for any of the studied variables and that the variables had negative growth over the first 36 months and had continued showing a decline when it was possible to analyze by remainder of the period, and showed symmetry with the results of the companies non-sampled / No Brasil ocorreram mais de 6 mil transa????es de fus??es e aquisi????es (F&A) nos ??ltimos dez anos, e estas opera????es tem sido alvo de pesquisas acerca dos seus efeitos, resultando em conclus??es divergentes quanto aos reflexos destas opera????es, principalmente a respeito dos benef??cios aos acionistas no tocante ?? cria????o de valor econ??mico, motivando esta pesquisa a buscar explica????es te??ricas poss??veis de confirma????o emp??rica acerca das F&A.

The Equity Affection, an option for the incorporatior, had the aim of giving more security to purchasers and to under construction real state providers, demanding more transperency regarding some provided information. The incorporators should maintain the complete accounting of posted ventures under such a system. Concerning RET, it can be stated that it was a way of making incorporation adhere to equity, with an only taxation of 7% under the billing, enclosing the Income Tax, the Social Contribution on Net Income, the Employers?? Profit Participation Program and the Social Contribution on Billing. Therefore, the aims of this work are to verify if there is an advantage for incorporations when using the RET, as a means of making them decide on the Equity Affection and analyze the market??s point of view about such a matter. In order to accomplish this, there had been carried out two pieces of research, one of which was made with 30 incorporations trial balances, located in S??o Paulo City, contributed by the Taxable Income, and a second one, through a quaetionnaire, as a way of verifying the knowledge of enterprises about such a matter. The results of the first research demostrated that there would be an avantage if the RET were used by the majority of the sample enterprises. However, it would not be an advantage in all moments of the research. Such an advantage can be obtained when there is a simulation of the same calculations, but this time with a reduction of 0,5% in the determined Income Tax by the legislation. The comparison between the RET and the anticipated profit demonstrated that for enterprises which have the possibility of anticipating profit, if it is not worthy the use of RET. This is due to their already contributing by an Income Tax lower than the redefined 7% in the new legislation. At least, it would be necessary a reduction of 1% in the Income Tax for attracting such enterprises. Concerning the second piece of research ( about the knowledge and utility of the Equity Affection and the RET by the incorations), such a research had showed that the present subject should be studied deeply. Few enterprises had already used such a system in the ventures, and most of them had not studied the subject yet as a means of predicting its future use. / A aprova????o da Lei n?? 10.931/04 criou o Patrim??nio de Afeta????o e o Regime Especial de Tributa????o - RET, para a atividade imobili??ria. A afeta????o patrimonial, na forma de op????o do incorporador, visou dar maior seguran??a aos compradores e financiadores de im??veis em constru????o, exigindo maior transpar??ncia nas informa????es prestadas. Os incorporadores dever??o manter contabilidade completa dos empreendimentos lan??ados sob esta sistem??tica. J?? o RET foi uma forma de incentivar as incorporadoras a aderirem ?? afeta????o, com al??quota ??nica de 7% sobre o faturamento, abrangendo o Imposto de Renda, Contribui????o Social Sobre o Lucro L??quido, PIS e COFINS. Os objetivos deste estudo s??o verificar se o RET ?? vantajoso para as incorporadoras a ponto de lev??-las a optar pelo mecanismo de afeta????o e analisar a vis??o do mercado sobre o tema. Para tanto, duas pesquisas emp??ricas foram realizadas, uma com 30 balan??os de incorporadoras sediadas na Grande S??o Paulo, tributadas pelo Lucro Real, e outra, com aplica????o de question??rio, para verificar o grau de conhecimento das empresas sobre o tema. Os resultados da primeira pesquisa indicam que seria vantajosa a utiliza????o do RET para a maioria das empresas da amostra, sem, contudo, ser vantagem em todos os per??odos da pesquisa, vantagem esta que se obt??m quando se simula os mesmos c??lculos com uma redu????o de 0,5% na al??quota determinada pela legisla????o. A compara????o entre o RET e o Lucro Presumido mostrou que ??s empresas com possibilidade de presun????o do lucro n??o ?? vantagem a utiliza????o do RET, pois j?? s??o tributadas por al??quota menor do que os 7% determinados na nova legisla????o, seria necess??ria uma redu????o de, pelo menos, um ponto percentual na al??quota para que sua utiliza????o fosse atrativa a estas empresas. Quanto ?? segunda pesquisa, sobre o conhecimento e utiliza????o do Patrim??nio de Afeta????o e do RET pelas incorporadoras, mostrou que o tema precisa ser mais estudado e discutido. Poucas empresas j?? utilizam esta sistem??tica em seus empreendimentos e a maioria ainda n??o fez estudos sobre o tema, visando futura utiliza????o.

At the same time, the need for environmental preservation and the tendency of scarcity of natural resources make the construction invest in researching new concepts, methods and materials for building systems for the sustainability of their economic activities. Thus arises the need to obtain building materials with low power consumption, capable of reducing the growing housing shortage of rural and urban population. Currently, research has been conducted on this topic to better understand the cementitious and pozzolanic reactions that occur in the formation of the microstructure of the soil-cement when added to other materials such as, for example, lime, and the relationship between microstructure and formed interfaces with the physical, mechanical and chemical analysis in compounds made from these ternary compositions. In this context, this study aimed to analyze the results of the influence of the incorporation of lime to the soil-cement to form a ternary mixture to produce soil-cement bricks and mortar without structural purposes. From the inclusion of contents of 6 %, 8 %, 10% and 12% lime to the soil, and soil-cement mixes in amounts of 2 %, 3 %, 4 % and 5 % were shaped-bodies of -cylindrical specimens to determine the optimum moisture content and maximum dry apparent specific weight. Then they were cured, and subjected to the tests of compressive strength, absorption and durability modified. Compositions obtained the best results in the tests performed on the bodies-of-proof cylindrical served as a parameter for molding of solid bricks, which underwent the same experimental methodology previously cited. The raw materials used, as well as compositions in which the bricks were molded solid, were characterized by physical and chemical tests, X-ray diffraction and scanning electron microscopy. The results obtained in the study indicate that the compositions studied, that showed the best results in terms of compressive strength, water absorption and durability ternary composition was soil, 10 % cement and 2 % lime / O uso de aglomerantes no solo para a produ??o de tijolos maci?os ? uma t?cnica construtiva antiga que tem sido utilizada por diversas civiliza??es ao longo do tempo. Ao mesmo tempo, a necessidade de preserva??o ambiental e a tend?ncia de escassez dos recursos naturais fazem com que a constru??o civil invista na pesquisa de novos conceitos, m?todos e materiais para os sistemas construtivos visando ? sustentabilidade econ?mica de suas atividades. Sendo assim, surge a necessidade de se obter materiais de constru??o com baixo consumo de energia, com capacidade de reduzir o crescente d?ficit habitacional da popula??o rural e urbana. Atualmente, pesquisas t?m sido realizadas sobre esse tema, visando compreender melhor as rea??es ciment?cias e pozol?nicas que ocorrem na forma??o da microestrutura do sistema solo-cimento quando adicionados outros materiais, como, por exemplo, a cal, e a rela??o existente entre a microestrutura formada e suas interfaces, com as propriedades f?sicas, mec?nicas e qu?micas verificadas nos compostos produzidos a partir dessas composi??es tern?rias. Nesse contexto, esse trabalho teve por objetivo analisar os resultados da influ?ncia da incorpora??o da cal ao solo-cimento para compor uma mistura tern?ria para produ??o de tijolos de solo-cimento e cal sem fins estruturais. A partir da inclus?o de teores de 6 %, 8 %, 10 % e 12 % de cal ao solo, e em misturas de solo-cimento nos valores de 2 %, 3 %, 4 % e 5 %, foram conformados corpos-de-prova cil?ndricos para determina??o da umidade ?tima e do peso especifico aparente seco m?ximo. Em seguida os mesmos foram curados, e submetidos aos ensaios de resist?ncia ? compress?o simples, absor??o e durabilidade modificada. As composi??es que obtiveram os melhores resultados nos ensaios realizados nos corpos-de-prova cil?ndricos serviram de par?metro para moldagem dos tijolos maci?os, que passaram pela mesma metodologia experimental anteriormente citada. As mat?rias-primas utilizadas, bem como as composi??es em que foram moldados os tijolos maci?os, foram caracterizadas atrav?s de ensaios f?sicos e qu?micos, difra??o de raios X e microscopia eletr?nica de varredura. Os resultados obtidos na pesquisa indicam que das composi??es estudadas, a que apresentou melhores resultados em termos de resist?ncia ? compress?o simples, absor??o de ?gua e durabilidade foi ? composi??o tern?ria de solo, 10 % de cimento e 2 % de cal

With regard to the methodology applied in this work, both descriptive and quantitative researches can be observed. These were carried out by using secondary data collection and statistical analysis. The aim of the survey was to check if the announcements of M&A operations produced impact on the prices of stocks publicly negotiated on BM&FBOVESPA after the global financial crisis in 2008. An event study was carried out in order to verify the existence of statistically significant abnormal returns around the dates of the announcements of the M&A processes, based on the assumption that a link between the stock market and companies decision to join an M&A process exists. The results obtained with the segmentation of the sample between acquiring and acquired companies indicate that announcements of M&A operations did not impact on the prices of publicly traded shares on the BM&FBOVESPA, during the research period, showing evidence of the informational efficiency of the Brazilian capital market as being semi-strong. When making up the segmentation between companies that had a change in control, both the acquired companies as the acquiring firms had positive abnormal returns, a fact that repeated itself in the segmentation carried out with regard to the payment method / Este trabalho procurou estudar a rea????o do mercado de capitais Brasileiro diante do an??ncio de um processo de Fus??es e Aquisi????es (F&A), investigando seu impacto no pre??o das a????es negociadas na Bolsa de Valores, Mercadorias e Futuros de S??o Paulo (BM&FBOVESPA). Com rela????o ?? metodologia aplicada neste trabalho, podem-se observar pesquisas de natureza descritiva e quantitativa, realizadas com coleta de dados secund??rios e an??lise estat??stica. O problema estudado foi verificar se os an??ncios de opera????es de F&A produziram impacto nos pre??os das a????es negociadas publicamente na BM&FBOVESPA ap??s a crise financeira global de 2008. Tendo como pressuposto a liga????o existente entre o mercado de capitais e a decis??o das empresas em ingressar num processo de F&A, foi realizado um estudo de evento com o intuito de verificar a exist??ncia de retornos anormais estatisticamente significantes em torno e na data do an??ncio de um processo de F&A. Os resultados obtidos com a segmenta????o da amostra entre empresas adquirentes e adquiridas indicam que os an??ncios de opera????es de F&A n??o produziram impacto nos pre??os das a????es negociadas publicamente na BM&FBOVESPA, durante o per??odo pesquisado, demostrando ind??cios da efici??ncia informacional do mercado de capitais Brasileiro na forma semiforte. Ao efetuar-se a segmenta????o entre empresas que tiveram mudan??a de controle, tanto as empresas adquiridas quanto as empresas adquirentes obtiveram retornos anormais positivos. Fato que se repetiu na segmenta????o efetuada com rela????o ?? forma de pagamento

In this period, the years of 2006 and 2007 were marked by particularly strong concentration of IPOs in the Brazilian market, and in the same way that other companies, real estate companies turned to the stock market in an unusual high frequency to finance their operations. Specifically in the real estate industry, a high percentage of companies went public in these two years: 60% of all companies in the sector. Studies on the annomalies due to IPOs usually address the undervaluation of the issuing companies, the concentrated emission at hot market times (Market Timing) and the poor performance of stocks and operations of these companies in the long run. Thus, this work aimed to investigate whether there was a relationship between the poor performance of the real estate industry in the Brazilian market and the significant number of IPOs that companies of this sector performed. For this purpose, non-financial companies from all sectors traded at BOVESPA were studied, comparing the market value divided by total assets of the companies that went public in the period with companies that was already traded. Furthermore, the behavior of the same indicator for real estate developers was contrasted with other sectors. In order to isolate any other incident effects on the test variable, different panel data regressions were estimated, controlling for risk, size, profitability, growth, years and sectors. Empirical evidence suggests that the poor performance observed in the real estate developers would be linked to the unusually high incidence of IPOs in the sector in the period, not to any particularities of these companies, directing the results primarily to issues of Market Timing in the IPO market timing, not to any operational difficulties in the real statebusiness. / When compared to other Brazilian companies traded at BOVESPA, real estate listed companies, in the period 2005-2013, had a sharp drop in market value.

Neste intervalo, os anos de 2006 e 2007 foram notadamente marcados por forte concentra????o de IPOs no mercado brasileiro, e da mesma forma que outras empresas, as incorporadoras imobili??rias recorreram com frequ??ncia pouco usual ao mercado acion??rio para financiamento de suas opera????es. Especificamente no setor de incorpora????o imobili??ria, um percentual elevado de empresas abriu capital nestes dois anos: 60% do total de empresas do setor listadas na BOVESPA. Estudos sobre anomalias decorrentes da abertura de capital costumam abordar a subavalia????o das empresas emissoras, a concentra????o das emiss??es em momentos de alta (Market Timing) e o fraco desempenho das a????es e opera????es destas empresas no longo prazo. Assim, esta disserta????o teve como objetivo principal investigar se houve rela????o entre o fraco desempenho do setor de incorpora????o imobili??ria no mercado acion??rio brasileiro com a expressiva quantidade de IPOs que as empresas que comp??em o setor realizaram. Com este objetivo, foram estudadas empresas n??o financeiras de todos os setores negociadas na BOVESPA, comparando-se o valor de mercado sobre ativo total das empresas que abriram capital no per??odo com o de empresas que j?? possu??am capital aberto. Ademais, verificou-se o comportamento do mesmo indicador para incorporadoras imobili??rias, contrastando-as com empresas de outros setores. Com a finalidade de isolar outros efeitos incidentes sobre a vari??vel de teste, diferentes regress??es com dados em painel foram estimadas, controlando-se risco, tamanho, rentabilidade, crescimento, anos e setores. Os resultados encontrados sugerem que, em m??dia, as empresas que recorreram ao mercado acion??rio, realizando IPOs entre 2005 e 2013, iniciaram o per??odo sobrevalorizadas, ou seja, com valor de mercado sobre ativo total superior ??s demais, sendo que esse valor teve forte decr??scimo nos anos seguintes. As evid??ncias emp??ricas sugerem que o fraco desempenho observado nas incorporadoras imobili??rias estaria ligado ?? anormalmente elevada incid??ncia de IPOs no setor no per??odo, e n??o a particularidades destas empresas, direcionando os resultados principalmente para quest??es de Market Timing nos IPOs, e n??o a eventuais dificuldades operacionais no ramo de atividade de incorpora????o imobili??ria.
