The Sarbanes-Oxley (SOX) Act of July 2002 was created to address the financial malfeasance revealed during the investigations of several large firms by the Securities and Exchange Commission (SEC). The Act required public companies traded on U.S. exchanges to provide increased transparency in financial statements. Key portions of the legislation required firms to create internal financial controls and placed personal accountability with top executives. SOX mandated and standardized a greater degree of self-regulation. In the years following SOX, firms experienced significantly higher compliance costs, but they also benefited from the reduction of statement errors and fraud, increased accuracy in reporting, and greater investor confidence. After the Sarbanes-Oxley (SOX) Act of 2002, anecdotal evidence suggested that SOX impeded small, research intensive firms. We looked at research intensive firms going public before and after SOX to determine if there was a change in volume and quality of research intensive firms post-SOX. We found that firms that went public after SOX were fewer and had lower patenting activity. In the case of small and medium size firms, the cost of SOX compliance is likely to divert funds from research investments. We speculate that highly research intensive firms are more likely post-SOX to divert their IPO to non-U.S. exchanges, delay going public, or dismiss the idea of going public, as proposed in a “3Ds” model. The 2002 SOX US Congressional Act levied millions of dollars in new compliance costs on each foreign or domestic firm that went public on U.S. exchanges. Funding for regulatory expenditures must come from somewhere. We proposed that one likely candidate was research budgets, as research efforts have a more distant, less immediately visible, long term effect on firm performance. We suggested that large firms more easily absorbed the additional costs of SOX with a reduced effect on research and development budgets, while small firms were less able to maintain research budgets after SOX. In the aftermath of SOX, research spending did go down, most visibly in Biotech and Electronics. As the total number of IPO firms decreased dramatically after SOX, these two research intensive industries, plus Computer Software, were the only industries with a large enough sample size to evaluate. We saw that research intensive firms diminished dramatically, along with many non-research intensive firms, from IPO events after SOX. Where we had sufficient sample size, in computer software, biotechnology, electronics, and “other”, we noted that research-intensive firms generally resisted the temptation to raid research budgets, finding funding for compliance elsewhere within the company or from the additional cash flow at time of IPO. Where firms did appear to greatly reduce research budgets was in the non-research intensive industries, where research budgets might be more of a discretionary expense. Firm size was not a factor in whether research intensive firms could better absorb the costs of SOX, although smaller firms tended to spend proportionally more on research in an effort to grow faster. After the enactment of SOX, we observed an indication that the markets valued research intensity even more than prior to SOX, perhaps understanding the vulnerability of research budgets being diverted to compliance costs. Overall, the data suggested that the effect of SOX was underestimated in this study, as the firms that were deterred from going public on U.S. exchanges were not in the sample evaluated. We only analyzed those firms prepared to accept the higher costs of SOX. The data set consisted of survivors, selected firms still willing to pay for SOX compliance as well as for research programs.

Full textThe 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.

Full textIntroduction: Historically, IPO’s have often been underpriced, which has resulted in a high initial return on average, i.e. high return on the first trading day. This has created the perception that new introduction is a good investment option for those who want an abnormal return. Purpose: The purpose of this study is to examine whether the short- and long-term performance of IPO’s are affected by variables as firm size, firm age, industry affiliation, issue period and gender diversity on board of directors. The purpose is also to determine whether IPO’s are underpriced and if they underperform in the long run. To study this, Initial Public Offerings on First North, Aktietorget and Stockholmsbörsen during the period of 2013 to 2014 have been analyzed. Methodology: To implement this study, a quantitative approach has been applied. Furthermore, a deductive approach was used since the purpose was to analyze the collected material based on previous research. The data selection consists of 56 firms were the secondary data has been obtained from Nasdaq OMX, Nordnet website, Avanza website and The Swedish Tax Agency. Theory: The theoretical frame that the study is based on consists of theories that were created regarding how IPO’s perform in short- and long-term and why they perform as they do. Furthermore, earlier research is presented which examine how gender diversity in board of directors affect corporate performance. Result and conclusions: The result in this study shows that in the short run, IPO's are overpriced due to a negative initial return. Further, the result show that IPO's outperform other companies, and the most underpriced shares perform better in the long run. For the dependent variables size, age, industry affiliation, listing period and gender diversity, no relationship of statistical significance could be found.

Going public is an incredibly exciting and dynamic event in a company's life. The company and its management are transformed and will forever have to conduct their business differently. During the mid to late 1990s, many companies went public, creating multitudes of instant millionaires overnight, from company executives to administrative staff. Many people recognized that Initial Public Offerings (IPOs) tend to significantly increase in price on the first day of trading. As a result, there have been many academic studies to try to determine the rationale as to why IPOs are typically underpriced. Most of these academic studies have focused on the analysis of 1 st day pricing results and attempted to correlate these results to various hypotheses. We try to understand this phenomenon and corroborate the academic hypotheses by talking to those who set the offer price -the investment bankers, underwriters, and company managers- to find out why underpricing occurs. This thesis provides the reader with a better understanding of how companies are valued and the initial offering price determined, and explain the differences in opinion between academics, bankers, and management as to why underpricing occurs. To accomplish this task, we first focused on capturing underwriters' opinions regarding the valuation and pricing of IPOs. We then interviewed executives that had taken companies public to compare and contrast their views with those from the bankers, and compared them to the conclusions from academics' research.

Full textThis dissertation consists of three essays. In the first essay, we investigate whether the control-ownership divergence can explain IPO long-run performance in France. Using data from a sample of 351 French IPOs during 1997-2011, we find that the separation between ownership and control rights of the largest shareholder is negatively associated with long-term performance of French IPOs. This finding indicates that IPOs with disproportional ownership structure underperform other firms in the one- to five-year period following the initial offering. Such separation induces controlling shareholders to extract private benefits of control to the detriment of minority shareholders.In the second essay, we examine the effect of lockup agreements on management earnings forecasts in initial public offering (IPO) prospectuses. Using a sample of 303 forecasts of French firms that went public over the period 1997–2013, we find that IPOs with lockup clauses are more likely to disclose conservative profit forecasts. Moreover, we provide evidence that IPOs with more shares to lock up, as well as those selecting longer lockup periods, have more accurate management earnings forecasts. These results are robust to a number of sensitivity tests.In the third essay, we examine the impact of geographic location on the short–run underpricing of French initial public offerings (IPOs). The results show that firms located in close proximity to the financial centre, Paris, are less underpriced than distant ones. These findings provide empirical support to the argument that uncertainty about IPO value increases with distance from Paris. In other words, geographic proximity improves the quality of collected information on IPO firms, which lowers their costs of going public and decreases the level of initial returns

The purpose of this study is to investigate whether the intellectual capital, which is not recorded in the financial statements, could influence the magnitude of IPOs underpricing. The paper first classify the financial and the non-financial intellectual capital into the human capital, the customer relation capital, the process capital, and the innovation capital. We further examine the relationship of these variables and the IPOs underpricing, offer price, and initial returns, and then find the core intellectual capital items and its measurement indices. These results show that information asymmetry exists among firms, underwriters, and investors, due to the unrecognized intellectual capital. Compared with general investors, firms and underwriters could easily identify the impact of unreconized Intellectual Capital on the intrinsic value of firms, because of their information advantage. Moreover, the intellectual capital has some impacts on the IPOs offer price and the honeymoon period stock price. Therefore, the initial returns is due to the reaction of underwriters and investors who think the unrecognized intangible assets of intellectual capital has the influence on the valuation of firm instead of investors’ over reaction to the valuation of firm.

According to the law, securities firms can be securities underwriter, securities dealer, and securities broker in the same time. However, there are always conflicts of interests between these three departments. Most early literatures focus on conflict of interests between only two of the three departments. This paper is the first attempt to link the three departments and examine their relationships as a whole. We use the recommendation data of brokerage department and trading data of stock trading department to calculate conflict of interest index of each securities firm. Then we examine the relationship between conflict of interest index and the performance of underwriting department. If a securities firm gets lower degree of conflict of interest index, we may infer that it has better reputation than the others. If information transmission effect does exist, the better reputation should result in better performances of the IPO stocks .The hypothesis is that the securities firms which have lower degree of conflict of interests index will have better prestige, so the IPO stocks underwritten by them will have higher abnormal return. The sampled data are IPO stocks first traded on the public stock exchange market in the year between 2001-2003 and 2007-2009. We use event study methodology to measure the performance of IPO stocks. The results show that: (1) there are negative correlation between conflict of interest index of securities firms and the performance of IPO stocks. The group of securities firms which have negative conflict of interests index have higher CAAR on IPO stocks than those who have positive conflict of interests index. (2)After ignoring the first day return, we find the group of securities firms which have positive conflict of interests index attempt to lower the IPO price. Then these IPO stocks are easy to have abnormal return in the beginning.

To analyze the performance of firms, this study investigates the long-run performance of 3,827 initial public offering firms (IPOs) from 1982-1994. Among the 3,827 IPOs, 1,053 firms are venture-backed and 2,774 firms are not. The result shows that the long-term underperformance improves gradually after 5 years, and the cumulative abnormal returns show an upward trend after the 6th year. This might be due to the fact that market competition eliminates 36% firms and leaves strong firms. This result also implicate that larger scale, higher visibility, expected growth, and venture-backed firms have a better performance. Therefore, this study suggests that it is a good strategy for investors to buy and hold the venture-bakced firms surviving more than 8 years in hi-tech industries with growth potentiality.

This research discusses the effect of management quality, towards top management team (TMT), on performance of firm’s initial public offerings. We investigate if better magangment quality affects investors’ strategic decisions in firm’s IPOs. In general, family firms have relatively less agency problems compared to non-family firms in its IPOs. This study selects 171 initial public offering firms in the Taiwan Stock Exchange Market from March 2005 to December 2013. The multiple regression analisis could be used to run the relationship of variables in sample firms including three major management quality dimensions: management team resources, management team structure and outside reputation of management team. The result of study shows: 1. In different IPOs underwriting price ranges, the important factors of management quality are different. It shows that team reputation is negatively related to high underwriting price range in family firms. But the relationship between team reputation and high underwriting price range is positive in non-family firms. 2. In different IPOs underpricing ranges, the influential factors of management quality are different. Basically management quality in non-family firms has significant relationship with underpricing range in defferent underpricing range. 3. Management quality has a strong influence on IPOs offer size in family or non-family firms. But it shows different impact factors. 4. Management quality severely affects numbers of IPOs co-underwriter in non-family firms. 5. Regardless of family or non-family firms, institutional investors have more intention to invest the firms with high ratio experienced management team in IPOs firms.

Abstract Investors generally expect to gain excessive returns on newly issued stocks during the period of IPOs, which is so called “honeymoon period”. Most of the previous studies found that the abnormal returns of IPOs do exist for various honeymoon periods and returns. The purpose of this study is to examine whether if the abnormal returns exist and analyze the significant factors that affect the abnormal returns. In the study, the predicted returns of newly issued stocks on the initial 5 days、15 days and 30 days was estimated from the returns from the 60thday to the 180th day after the stocks have been listed on the exchange. Then test were conducted to see if the abnormal returns are significantly higher than zero on the three periods mentioned above. In addition, a multiple regression model was built to analyze the determinants of the abnormal returns. The empirical findings include: (1)there exist significant abnormal returns for the whole sample on 15 days and 30 days; (2) the abnormal returns for the OTC stocks are significantly higher than the exchange-listed stocks;(3)the abnormal returns during the bull market are significantly higher than during the bear market;(4) the abnormal returns of traditional electronic firms are significantly higher than the non-traditional electronic firms. The regression results indicate that the factors affecting the abnormal returns are: (1)the ratios of internal shareholders and venture capitalists are positively correlated with the abnormal returns;(2) non-traditional electronic firms have significantly lower abnormal returns;(3) the impact of the methods of underwriting and over-subscription on abnormal returns depends on various periods and sample groups.
