The underpricing of IPOs on the stock exchange of Mauritius

This paper investigates the underpricing of IPOs on the Stock Exchange of Mauritius (SEM). Taking into account the whole population of firms which went public since the inception of the SEM until 2010, the results show an average degree of underpricing within the range 10 to 20%. Using a regression approach, we demonstrate that the aftermarket risk level and auditor's reputation both have a significant positive impact on initial returns. We propose the use of the Z-score as a composite measure of a firm's ex ante financial strength, and find that it has a significant negative effect on the degree of short-run underpricing.

Urban economic openness and IPO underpricing

We examine the empirical impact of trade openness on the short-run underpricing of initial public offerings (IPOs) using city-level real estate data. This paper represents a first attempt to employ a macroeconomic approach to explain IPO performance. We investigate an openness effect in which urban economic openness (UEO) has a significant impact on the productivity and on the prices of both direct and indirect real estate due to productivity gains of companies in more open areas. This in turn positively affects the firm’s profitability, enhancing the confidence in the local real estate market and the future company performance and decreasing the uncertainty of the IPO valuation. And as a result, we find that issuers have less incentive to underprice the IPO shares. China provides a suitable experimental ground to study the immense underpricing in developing markets, which cannot solely be accounted for by firm specific effects. First, Chinese real estate companies show strong geographic patterns focusing their businesses locally – usually at a city level. Second, we observe a degree of openness which is significantly heterogeneous across Chinese cities. Controlling for company-specific variables, location and state ownership, we find the evidence that companies whose businesses are in economically more open areas experience less IPO underpricing. Our results show high explanatory power and are robust to diverse specifications.

Initial public offerings in Australia 1994 to 1999, recent evidence of underpricing and underperformance

This paper analyses whether financial and non financial characteristics of Australian initial public offerings (IPOs) can explain observed underpricing and long term underperformance over the period 1994 to 1999. A number of previous Australian studies have investigated initial day underpricing and longer term underperformance of IPOs and this study updates those papers. We find that initial day underpricing can in part be explained by market sentiment, forecast dividend per share yields, underwriter options and share options. Our longer term analysis supports the finding of previous studies in that IPOs on average, underperform the market in the first year following their listing.

Intangible assets and the underpricing of industrial company initial public offerings

This study analyses 262 industrial company initial public offerings (IPOs) in Australia from 1994 to 1999. It finds that the identification and valuation of brand name, trademark, patent and capitalized research and development cost intangible assets in the prospectus significantly reduces underpricing. The identification of goodwill and license cost intangibles does not appear to be significant to underpricing. This paper supports the Beatty and Ritter (1986) argument that IPOs may display financial and nonfinancial characteristics that lower the uncertainty about the value of the lPO and hence lower the underpricing of that IPO. Our findings suggest implications for the issuer who wants to maximize the value of the firm at the time of the lPO, the underwriter who is required to guarantee the success of the capital raising and for the initial investors who are looking to reduce their uncertainty about the valuation of the lPO.

Characteristics and underpricing of Australian mining and energy IPOs from 1994 to 2001

This paper follows How (2000) who examined 130 Australian mining and energy initial public offerings (IPOs) from 1979 to 1990 to report an average 107.18 % underpricing return by those IPOs. This study updates that report by investigating 127 Australian mining and energy IPOs from 1994 to 2001 to find a substantially lower 17.93 % average first day return. These updated findings have implications for both new companies seeking to float and also for the subscribers wishing to invest in these new listings.

Conflicts of interest and china's A-Share underpricing

The extremely high A- share underpricing in China's primary market provides us with a very interesting area of empirical research. Previous studies on China's IPO underpricing have been suggestive, but in-conclusive. We investigate the A- share underpricing by employing the most recent data available. A significant decline in A- share underpricing is found in 2003 relative to previous years (and much less than that recorded in the literature to date). We examine the validity of previous A- share underpricing models, reported in the literature, and find a statistically significant structural break in the data during 2003 when these models are specified. We further explore conflicts of interest in the Chinese IPO market and specify an alternative class of models to further examine this change in observed market behaviour. Our results suggest that a contract with high underwriter's fee leads to less A- share underpricing. Our results also suggest that the asymmetric information hypothesis does not apply in the Chinese !PO market in 2003. Overpricing by the secondary market and the trading activity on the first trading day are the main functions of the A- share underpricing. This study has important implications such as guiding the Chinese government policy regarding the regulations of Initial Public Offering.

Differences in underpricing returns between REIT IPOs and industrial company IPOs

This paper follows Chan, Stohs, andWang (2001), which argues that the underlying value of the real estate is not by itself the reason for the very substantial differences in underpricing returns between real estate investment trust (REIT) IPOs and industrial company IPOs.We use variables identified in previous studies that have helped explain the underpricing of industrial company IPOs to help explain the underpricing of property trust IPOs. We find that the prospectus forecast dividend yield is a critical variable in the valuation and hence underpricing of REIT IPOs compared to industrial company IPOs. The sentiment towards the market and whether or not the issue is underwritten also impact the underpricing of REITs but the impact is much less than on industrial company IPOs.

Underpricing of energy IPOs in Australia

The underpricing of initial public offerings (IPOs) has been discussed in the literature for over thirty years. Underpricing is the term used when the issue price of the shares of a company raising public equity capital and seeking to list on a stock exchange is below the closing price of the shares on the first day of listing. As such, underpricing theoretically allows subscribing investors the opportunity of making a return on the day of listing. The international evidence as examined in [4] and updated in [5] has documented that subscribing investors made handsome double-digit' (for example US IPOs - 15.7%, UK IPOs 12%, Turkish IPOs - 13.1 %, Greek IPOs -49.0%) or even triple-digit (for example Chinese IPOs 256.9%) statistically significant positive first day returns, on average. These studies are generally however of industrial company IPOs.

The purpose of this paper is to investigate the underpricing returns of Australian energy IPOs from January 1994 to June 2007. Two previous studies into natural resource IPOs in Australia only made fleeting mention of energy IPOs because of the small sample sizes. [3] identified 2 solid fuel IPOs and 13 oil and gas IPOs (amongst 130 other natural resource IPOs) during 1979 to 1990 and advised average underpricing returns of 106.5% and 47.3% respectively for investors subscribing to these IPOs. [2] investigated 19 energy IPOs (amongst 96 other natural resource IPOs) from 1994 to 1999 and reported an average underpricing return of 8.3%.

The sample set of 134 used in this study is significantly greater than previous Australian studies. These 134 energy IPOs raised over $1.945 billion of public equity capital from January 1994 to June 2007. [3] reports on the importance of the natural resources sectors to Australia's economy and the fact that companies working in these sectors constitute around one third of the entities listed on the Australian Stock Exchange.

This study also follows a highly influential paper in the IPO literature by [I]. They argue that the lower the uncertainty about the value of an IPO, the lower the underpricing needed to attract subscribers. Given the linkage between uncertainty and underpricing, this study seeks to identify the factors that might influence uncertainty and hence underpricing.

The study found that the mean underpricing return for these energy lPOs is 22.8% and statistically significant. The model used to investigate variables that might help explain the level of underpricing in this industry sector is also particularly useful. An important finding in the study for new issuers, underwriters and subscribing investors is that those energy IPO firms that used underwriters had substantially lower underpricing. The other finding that larger issues are likely to have lower underpricing is consistent with prior industrial company IPO studies.

The underpricing of gold mining initial public offerings

This study is motivated by How [How, J., 2000. The initial and long run performances of mining IPOs in Australia. Aust. J. Manage. 25, 95–118] who examined 100 Australian gold mining initial public offerings (IPOs) from 1979 to 1990 to report an average 119.51% underpricing return by those IPOs. This study updates that analysis by investigating 114 Australian gold mining IPOs from 1994 to 2004 and finds a significantly lower 13.3% average first day return. Options offered to underwriters can in part explain these returns as can the change in either the Gold Index or the All Ordinaries Index from the date of the prospectus to the date of listing.

Audit quality, auditor compensation and initial public offering underpricing

We jointly study the impact of audit quality on auditor compensation and initial public offering (IPO) underpricing using a sample of Australian firms going public over the period 1996–2003. We find that quality (Big Four) audit firms earn significantly higher fees than non-Big Four auditors, and audit quality is positively associated with IPO underpricing. The positive relation between audit quality and underpricing is more pronounced for small issues, IPOs underwritten by non-prestigious underwriters, and those that are not backed by venture capitalists. Taken together, our results suggest that quality auditors serve as a signalling device that enhances post-issue market value of equity.

The underpricing of A-REIT IPOs in Australia during 2002 to 2008

This study analyses 45 Australian Real Estate Investment Trust (A-REIT) initial public offerings (IPOs) in Australia from January 2002 to June 2008, since the introduction of the single responsible entity to oversee the activities of listed property trusts (LPTs) Rather than the trustee and manager roles. The study finds that this sample of A-REIT IPOs had a significant 3.37% underpricing and that the direct costs of capital raising help explain this indirect cost of underpricing. There is some evidence to suggest that A-REIT IPOs that seek to raise more equity capital have less underpricing, while those that are subscribed to more quickly have higher underpricing. The findings offer insights for issuers who seek to maximize the value of the A-REIT at the time of the IPO, underwriters who guarantee the success of the capital raising and for investors who are looking to invest in Australian A-RE1T 1POs.
