L'introduction en bourse, en anglais : Initial Public Offering (IPO), est une étape majeure de la vie d'une entreprise. Bien préparée et opportunément décidée, l'introduction permet non seulement de trouver des fonds propres supplémentaires et de diversifier les sources de financement de l'entreprise, mais aussi d'acquérir notoriété et crédibilité à l'échelle nationale et internationale. La recherche s'inscrit dans un vaste courant de pensée économique qui porte sur le corporate governance. Elle a pour objectif de présenter les introductions en bourse sur les différents segments de l'Euro.NM entre 1997 et 1999 et les compare à des opérations similaires réalisées sur le NASDAQ. Elle analyse aussi leurs coûts qui peuvent être divisés en coûts explicites et en coûts implicites. Les coûts explicites concernent la rémunération des intermédiaires financiers, les campagnes de communication, etc. ; ils représentent, en règle générale, moins de 1% de la capitalisation boursière des sociétés étudiées. La recherche s'intéresse particulièrement aux coûts implicites qui sont liés à la sous-évaluation des titres à l'introduction, c'est-à-dire la différence entre le cours d'équilibre et le prix payé par les investisseurs lors de l'introduction. Les modèles théoriques n'expliquent que très partiellement l'existence d'une telle sous-évaluation. La thèse aborde successivement quatre thématiques : (i) la sous-évaluation initiale des introductions en bourse ; (ii) la structure de propriété ; (iii) la liquidité de ces opérations et (iv) la performance boursière à long terme (à trois ans) après l'introduction en bourse. Nos résultats empiriques confirment et prolongent les résultats obtenus sur les marchés anglo-saxons. Ils peuvent se résumer à six points principaux : (1) la sous-évaluation des introductions en bourse sur l'Euro.NM est en moyenne plus forte que celle des opérations équivalentes réalisées sur le NASDAQ ; (2) les actionnaires d'origine des sociétés de l'Euro.NM jouent un rôle plus important dans l'introduction en bourse en proposant plus de titres que ceux du NASDAQ ; (3) les marchés financiers ajustent les erreurs d'évaluation dès le premier jour de cotation ; (4) la sous-évaluation initiale d'une offre d'introduction peut aider à stabiliser la structure de propriété après l'introduction : cela signifie que les gros investisseurs sont discriminés dans le processus d'allocation du capital ; (5) une dégradation est observée dans la performance des entreprises étudiées du NASDAQ tandis que, sur notre échantillon Euro.NM, on note une performance boursière à long terme significativement positive ; finalement, (6) il ressort que les entreprises dont « la part détenue » par les actionnaires d'origine dans le capital est la plus importante semblent ne pas présenter de meilleures performances à long terme par rapport aux autres.

The concept of grandstanding comes from Gompers (1996), in his article, he defined “to grandstand” as “to act or conduct oneself with a view to impressing onlookers”. The idea of grandstanding does not only apply solely to venture capital but also could apply to underwriters of IPOs industry as well. IPOs activities provide huge revenues for underwriters, so underwriters compete with each other for IPO business. China’s stock market grows explosively after 2006, and it has the highest underpricing, as well as more and more underwriters have emerged recently, so our paper is constrained under Chinese stock market environment. We empirically examine whether inexperienced underwriters grandstand when they conduct IPOs in order to achieve more market shares, for example by deliberate underpricing or charging lower fee rates. This study is conducted from the underwriter’s perspective. We use two kinds of reputation measurement methods to define “inexperienced” and “prestigious underwriters” and employ a quantitative approach to analyze the data. Evidence from a sample of 392 IPOs from June 19, 2006 to March 24, 2010 suggests that inexperienced underwriters do not have incentives to grandstand. The number of IPOs that underwriters have conducted and recent IPO performance do not always contribute to a gain of market share directly. Therefore, inexperienced underwriters do not provide more underpriced IPOs nor do they charge lower fee rates. Evidence also marginally supports that underwriters do not intend to conduct small offer sized IPOs.

Using 196 reverse leveraged buyout (RLBO) transactions between 1981 and 2006, I examine the operational benefits to leveraged buyouts (LBO). Operational drivers of firm value are defined as: increases in gross profits, operating income, return on assets, net income, working capital management, and cash flow generation. Initial analysis supports the literature of minimal deterioration of post-IPO performance. Where most studies analyze RLBOs as a whole, I find that when broken into top and bottom performance group pre-IPO, data show performance increases for bottom performers and performance decreases for top performers. Top performing firms pre-IPO lose up to 50% of industry adjusted performance by five years after going public, consistent with the hypothesis that LBO structures increase efficiency.

Underwriter need to participate in the process of new issue firms going public. Related reference about Taiwan's underwriter IPOs market share haven't appear. In this study, we expect to find out the relationship between Taiwan's underwriter IPOs market share and some related factors. Then offer issuer, underwriter and investor the conclusion as reference. The IPOs samples are selected during the period 1991 through 2000 in Taiwan. There are 475 newly issued firms in this period. We subtract some incomplete data samples and bank samples.There are 247 IPOs samples in our regression model. Although underwriter IPOs market share is less significantly impacted by IPOs offer price , results imply that when offer price is too low,this would damage issuer's benefit and lead to underwriter IPOs market share decrease. When offer price is too high, this would damage investor's benefit and just lightly lead to underwriter IPOs market share decrease. Results show that there is no industry specialization in Taiwan's underwriter industry. Although underwriter IPOs market share is less significantly impacted by IPOs one year performance,results imply that when underwriter market higher one year return IPOs, this would attract more investors and lead to underwriter IPOs market share increase.Results show that underwriter IPOs market share is significantly impacted by nderwriter's asset and age. The underwriter with larger asset and larger age gains more IPOs market share.

In order to boost the exit value, it is not uncommon that issuers report earnings in excess of cash flow generated by its operations at the initial public offering (IPO). The discretionary activity of performing earnings management can mislead investors about the intrinsic value of the newly public firm. Within this study, I examine how earnings management will affect the stock market reaction upon the lockup expiration date, the IPO adjustable offering size, and how the backing of private equity or venture capital (PEVC) affects earnings management tendencies within IPO firms. Using a unique, hand-collected dataset of 56 Swedish newly public firms from 2007 - 2014, I show that IPO firms (i) manage their earnings at the full fiscal year prior to the IPO and that earnings management will result in a negative stock market reaction upon the lockup expiration date. More importantly, I show that (ii) high adjustable offerings do not affect this relationship indicating that earnings management has no impact on the adjustable part of the offering size within IPOs. I also find that (iii) IPO firms backed by PEVC firms are more eager to manipulate their earnings, and (iv) highly reputable PEVC firms do not mitigate the manipulation of earnings within IPO firms. The results taken together suggest that studying the stock market reaction on the lockup expiration date is important for manipulative IPO firm detection, and that a participation in IPOs backed by PEVC firms must be done with caution.

Ao longo do tempo o contexto da economia mundial e brasileira é de expansão, salvo alguns períodos de retração, onde a economia fica estagnada, a exemplo do momento atual que vivemos. Apesar disso, as produções de riqueza vêm crescendo nos últimos anos e, por consequência, as empresas brasileiras, de um modo geral, têm buscado se desenvolver da mesma forma. Para financiar este desenvolvimento as empresas podem captar recursos através de instituições financeiras com que se relacionam. Entretanto este modelo apresenta limitações em relação ao volume de crédito disponível e também tem se mostrado um dos mais caros do mundo. Desta forma buscam-se outras alternativas de financiamentos não convencionais, como por exemplo o Mercado de Capitais. Este mercado tem amadurecido bastante no Brasil nos últimos anos, tornando-se uma alternativa para as empresas que buscam acompanhar este crescimento. São inúmeras as vantagens proporcionadas, mas, por outro lado, também são muitas as dificuldades do processo de preparação para acessar a este mercado, principalmente pelo pouco preparo das empresas para atender níveis elevados de governança corporativa. O objetivo, então, nesse contexto, na esfera do mercado de capitais é de identificar quais são as adaptações necessárias para as empresas ingressarem neste mercado, através da Oferta Pública de Ações (IPO), bem como identificar quais as mudanças necessárias na empresa, suas regras e principais custos que envolvem a operação, além das exigibilidades legais com a implantação de IPO. Conclui-se que alternativas e soluções existem para as dificuldades encontradas, e que o desafio é justamente enfrenta-las, para o próprio amadurecimento da empresa e também para criar diferencial competitivo frente à concorrência. / Over time, the context of the global and the Brazilian economy's has been the expansion, except for some periods of retraction or stagnant, like the current moment that we are living. Nevertheless, the wealth of productions has been growing in recent years ended, consequently, in general, Brazilian companies has sought to develop in the same way. To finance their development, companies can raise funds through financial institutions. However, this model has limitations, like line of credit and volume, and also Brazilian cost has been one of the most expensive in the world. Thus, some companies are seeking others alternatives for unconventional financing, such as Capital Markets. That market increase a lot in Brazil, in recent years and became an alternative for companies that are seeking to monitor this growth. There are many advantages provided, and by the other hand, many difficulties in preparation of process to access the market, especially in to meet high standards governance corporate. The goal, then, in this context, is to identify what are the adaptations necessary for companies to enter in this market through Initial Public Offering (IPO), just like identified the necessary changes in the company, their rules and main costs involving on the operation, and in addition, legal liabilities with the IPO deployment. It is concluded, that there are alternatives and solutions to the difficulties find, and the challenge is to confront them, for to get the own maturity and also to create a competitive over the competition.

Estudos recentes, realizados principalmente no mercado norte-americano, trazem in-dícios de fatores determinantes para o resultado de longo prazo das emissões primá-rias de ações (IPOs, do inglês Initial Public Offerings). Porém, trabalhos com esse enfoque no mercado brasileiro ainda são escassos e inconclusivos, pois utilizam pe-quenas bases de dados e analisam horizontes de tempo de até dois anos. Buscando ampliar a análise de IPOs no mercado brasileiro, o objetivo desta dissertação foi es-tudar os determinantes do desempenho de longo prazo das IPOs realizadas na Bolsa de Valores de São Paulo com horizontes de tempo de três e cinco anos após o pri-meiro dia de negociações. A amostra foi composta por 97 emissões primárias de ações ocorridas entre 2004 e 2012 para o horizonte de três anos e 77 ocorridas entre 2004 e 2010 para o horizonte de cinco anos. O cálculo de retorno de longo prazo seguiu a metodologia de Buy-and-Hold Abnormal Return (BHAR), ajustado ao Ibo-vespa, e os possíveis determinantes do BHAR das IPOs foram submetidos a análises multivariadas através de estimações pelo método de Mínimos Quadrados Ordinários (MQO). Os resultados levam à conclusão de que o desempenho de longo prazo das IPOs brasileiras está positivamente relacionado com: 1) a Idade das firmas, 2) o nível de Governança Corporativa, 3) o Setor e 4) o Desempenho Operacional pós IPO. Pôde-se concluir, também, que o desempenho de longo prazo das IPOs está negati-vamente relacionado com: 1) o Retorno Anormal do Primeiro Dia de negociações, 2) a Quantidade de IPOs realizadas no Ano e 3) o Percentual de Investidores Institucio-nais na emissão primária. Os testes de robustez realizados apontam para uma relação também positiva entre o Crescimento do PIB do período pré IPO com o resultado de longo prazo das ações. / Recent studies, conducted mainly in the North American market, have presented evi-dence regarding decisive factors for the long-run performance of Initial Public Offerings (IPOs). However, the number of similar studies applied in the Brazilian market is yet limited and inconclusive, because they employ reduced databases and short time win-dows up to two years. Seeking to extend the analysis of IPOs in the Brazilian market, the purpose of this study was to explore the determinants of the long-run performance of IPOs held at BM&F Bovespa, with time windows of three and five years after the first trading day. The sample was composed of 97 initial public offerings occurred be-tween 2004 and 2012 for three-year horizon and 77 occurred between 2004 and 2010 for the five-year horizon. The long-run return calculation followed the methodology of Buy-and-Hold Abnormal Return (BHAR), adjusted to the Ibovespa index, and the pos-sible determinants of BHAR related to IPOs were subjected to multivariate analysis using Ordinary Least Squares (OLS) approach. The results lead to the conclusion that the long-run performance of Brazilian’s IPOs is positively related with: 1) Age of the Firms, 2) the level of Corporate Governance, 3) Sector and 4) post IPO Operating Performance. In addition, it was noticed that the long-run performance of IPOs is neg-atively related with: 1) the Abnormal Return of the First Trading Day, 2) the IPO amount held in the year and 3) percentage of Institutional Investors the IPO. Robustness tests were performed, and their conclusions highlighted a positive relationship between GDP growth of previous IPO period with the long-run performance.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O presente estudo teve como objetivo geral investigar a prÃtica de gerenciamento de resultados por parte das companhias nos perÃodos prÃximos ao de realizaÃÃo de oferta pÃblica de aÃÃes. A populaÃÃo do estudo compreende as companhias que realizaram oferta pÃblica de aÃÃes entre 2004 e 2013. Para realizaÃÃo do estudo, foram coletados dados financeiros trimestrais das empresas da amostra. O gerenciamento de resultados foi investigado numa perspectiva temporal, seguindo metodologia adotada por Gioielli (2008), que investigou o gerenciamento das informaÃÃes contÃbeis pelas empresas em processo de IPO e tambÃm em que momento ao redor desse processo essa prÃtica à mais intensa. Inicialmente, foram estimadas as acumulaÃÃes totais. Em seguida, foram estimadas as acumulaÃÃes discricionÃrias, que, por sua vez, sÃo obtidas por meio dos modelos Jones Modificado (1995) e Pae (2005). Foi utilizada a anÃlise de dados em painel para estimaÃÃo dos coeficientes, sendo consideradas as variÃveis das empresas-trimestre de todo o perÃodo. Os resultados encontrados nesta pesquisa sugerem que as empresas gerenciam seus resultados contÃbeis e que essa prÃtica à mais intensa nas fases compreendidas pelos trimestres anteriores aos trimestres anterior e posterior ao perÃodo da oferta pÃblica (fase 1) e ao de pÃs-vedaÃÃo à negociaÃÃo das aÃÃes da companhia (fase 4) e que procuram com mais frequÃncia reduzir seus resultados contÃbeis ao redor da oferta pÃblica de aÃÃes. O presente estudo contribuiu com a discussÃo do tema gerenciamento de resultados e obteve evidÃncias de que os investidores e os ÃrgÃos de fiscalizaÃÃo e regulaÃÃo do mercado de capitais no Brasil devem buscar alternativas para detectar e/ou inibir prÃticas oportunÃsticas da administraÃÃo das companhias durante a oferta pÃblica de aÃÃes. / The general objective of this study was to investigate the practice of corporate earnings management in the period surrounding a public offering. The study was based on quarterly financial data collected from a sample of firms traded on BM&FBovespa making public offerings between 2004 and 2013. The practice of earnings management was analyzed in the temporal perspective, following the methodology of Gioielli (2008) who investigated the practice and timing of accounting information management by firms making initial public offerings. Initially, total accruals were estimated, followed by discretionary accruals using the modified models of Jones (1995) and Pae (2005). Panel data analysis was used to calculate coefficients for a period of eight quarters (three before, one coinciding with, and four after public offering). Our results show that firms manage accounting results by reducing them, especially in the two quarters before the quarter preceding a public offering and after the end of the lock-up period. Intended as a contribution to the discussion on earnings management, the study reveals the need for investors and Brazilian agencies regulating and inspecting capital markets to devise alternative ways of detecting and/or inhibiting opportunistic results management practices in firms making public offerings.
