Excess Returns in Electric Utility Mergers During Transition to Competition

A standard event methodology is used to evaluate recent electric utility mergers as the industry moves to competitive generation markets. Statistically significant effects were focused on the day before the announcement and the day of the announcement, and were fairly small, although statistically significant. Shareholders perceive very little merger benefits occurring in a highly competitive generation sector. Markets reacted more positively to the gas/electric mergers, indicating stockholder appreciation for opportunities for scope economies. U.S. acquirers suffered no significant wealth losses in mergers with British and Australian utilities.     

Mergers and acquisitions as a response to the deregulation of the electric power industry: value creation or value destruction?

Many electric utilities, as a response to the deregulation of the electric power industry, adopted a strategy of acquiring other electric or gas utilities. We examine whether these merger and acquisition strategies create value for the utility shareholders and whether the strategies result in superior post-merger operating and stock-price performance relative to utilities that did not grow through acquisitions. We find little evidence that the mergers and acquisitions created long-term value for a fully diversified investor. Furthermore, the stock price and operating performance of the acquirers under performed the stock price and operating performance of a control portfolio of utilities that did not engage in merger activity.      

政府干预、政治关联与地方国有企业并购

本文以2001—2005年间发生的地方国有上市公司收购非上市公司的事件为样本,研究地方政府干预、政治关联对地方国有企业并购绩效的影响。研究发现:地方政府干预对盈利样本公司的并购绩效有负面影响,而对亏损样本公司的并购绩效有正面影响。这说明,出于自身的政策性负担或政治晋升目标,地方政府会损害或支持当地国有上市公司,这为政府"掠夺之手理论"和"支持之手理论"提供了实证支持。我们还发现,盈利样本公司的并购绩效与政治关联正相关。这表明,政治关联可以作为法律保护的替代机制来保护企业产权免受政府损害。     

Does the merger paradox exist even without any regulations? Evidence from Germany in the pre-1914 period

This paper measures the market response triggered by merger announcements in an environment without regulations and without a strong separation of ownership and control in Germany. Based on event study methods applied to daily data and regression analyses, I evaluate whether the merger paradox existed, and how firm size, the way of financing a merger, and industry factors influenced the success of acquirers. Hence, my study can shed some light on commonly believed explanations for the bad performance of mergers. The whole portfolio of acquirers exhibited positive cumulated abnormal returns, which indicates a rejection of the merger paradox—but market values of some companies declined. Particularly, acquiring banks lost shareholder value, although the majority of mergers occurred in the banking industry. Caused by the new exchange law, banks were in a merger wave. Therefore, alternative explanations like the minimax-regret principle might explain why banks merged in spite of lacking success.     

Can financial media sentiment predict merger and acquisition performance?

This paper explores whether and how media serves as an information intermediary in the capital market and predicts value creation from mergers and acquisitions (M&As). Using a sample of 288 M&A deals in the U.S. market from 2000 to 2015, this paper examines whether pre-merger news about acquirers correlates to M&A performance. The empirical evidence shows that a positive media attitude before merger announcements has predictive power for stock returns in both the short and long run. Moreover, media pessimism is associated with higher bid premiums, meaning that acquirers must raise the bid price to offset the negative effects produced by the media. These findings suggest that media news contains information relevant to M&A performance and thus has implications for shareholder wealth.     

Capital markets' assessment of airline restructuring following deregulation

The Airline Deregulation Act of 1978 propelled the industry into a constant state of change, even turmoil, that prevails 14 years later. The purpose of this paper is to examine the capital markets' reactions to the dramatic restructuring of the airline industry. The results of an event study of 24 merger announcements indicates that stockholders of target firms experience positive abnormal returns of 14.5% over a three-day period around the merger announcement date. Bidding firms experience a 3.7% increase over the same time window. Clearly, the capital markets viewed this restructuring of the industry as positive.     

The formation of public utility holding companies and their subsequent diversification activity

This paper examines the stock market reaction to announcements that utilities are converting to utility holding companies. There are negative abnormal returns associated with these announcements. Holding companies permit these utilities to diversify beyond the utility industry, and the announcements of their formation may signal the market of their intentions to diversify. The negative abnormal returns associated with these announcements and the negative abnormal returns associated with subsequent announcements of acquisitions are consistent with other research showing that diversifying bidders lose more (or gain less) than non-diversifying bidders.     

Information advantage,short sales,and stock returns: Evidence from short selling reform in China

We study short selling around earnings announcements and examine the potential sources of their information. Using unique daily aggregate short selling transactions in China, we find that short sellers significantly increase (decrease) their short positions before negative (positive) earnings surprise. In addition, abnormal high short selling is significantly associated with negative post-earnings announcement stock returns. The findings suggest that short sellers, on average, are informed and sophisticated traders and they can exploit profitable opportunities contained in earnings announcements. Finally, we find that stocks with poor governance or more insiders have higher (lower) abnormal short selling in negative (positive) earnings surprise, indicating private information leakage from firms with weak governance; which is consistent with the tipping argument. Our findings have important policy implications for capital market regulation in China.     

Unexpected Share Repurchase Announcements

Abstract

Open-market stock repurchase announcements are generally perceived by the stock market as a signal of firm undervaluation. Our study shows that repurchase announcements that were preceded by SEOs of other firms in the same industry within the prior six months (namely SEO-RPs) are more likely the result of lacking investment opportunities than signaling undervaluation, especially in concentrated industries. Specifically, we find investors response negatively to SEO-RP announcements while react positively to regular repurchase announcements. The higher the intensity of SEO activities in the industry, the more negative market reaction to SEO-RP announcements. We argue that the market doesn’t expect a repurchase announcement when other rival firms are raising more capital via SEOs. These SEO-RPs represent a negative surprise to the market and lead to a downward adjustment in value of the repurchasing firms in the announcement window. In the three-year post-announcement periods, the SEO-RP firms underperform regular repurchasing firms in both stock return and operating performance. Moreover, while regular repurchasing firms gradually increase their capital expenditures, SEO-RP firms significantly reduce their capital expenditures. These findings support our arguments that repurchase announcements that immediately follow SEOs of rival firms (SEO-RPs) more likely indicate the announcing firms entering a slower growth rate with fewer investment opportunities than signal the undervaluation problem. The underperformance in stock return and operation combined with a significant reduction in capital expenditures in the post-announcement periods are consistent with this logic and also explain why the market reacts negatively to SEO-RP announcements.     

The legal environment and corporate valuation: Evidence from cross-border takeovers

We examine the cumulative abnormal returns to U.S. targets, their foreign acquirers, and the target-acquirer portfolio in 181 successful cross-border tender offers during the period 1982–1991. We find that the incentive mechanisms created by the degree of shareholder-creditor rights protection and legal enforcement in the acquiring firm country can explain the observed variation in target, acquirer, and portfolio returns. We also find that foreign acquirers overpay for Delaware-incorporated targets. Our results are strengthened after controlling for deal-related effects addressed in the domestic mergers and cross-border investments literature.     

Investor Reaction to Inter-corporate Business Contracting: Evidence and Explanation

We examine the stock market reaction to 1227 inter-corporate ordinary business contract announcements reported by Dow Jones between January 1, 1990 and December 31, 2001. Around contract announcement dates, we find statistically significant positive average abnormal returns and abnormal trading volume for contractors, but insignificant positive abnormal returns and negative abnormal volume for contractees. Cross-sectionally, contract announcement period returns are higher for contractors who are small relative to the contract size, have higher return volatility, larger market-to-book ratios and higher profitability. The announcement period returns of contract-awarding firms are not significant and are only marginally related to cross-sectional explanatory factors. The results are consistent with two explanatory stories: contractor quasi-rents induced by the winner's curse and information signalling about contractor production costs. The results are not consistent with perfect competition, with contracts having positive net present values for both parties, and with a version of incomplete contracting theory.     

How do investors respond to Green Company Awards in China?

We find that firms winning Green Company Awards in China from 2008 to 2011 experienced on average insignificant and in some cases significantly negative effects on shareholder value. Various robustness checks suggest that these findings are not driven by the inefficiency of the Chinese stock market or a lack of perceived credibility of the award. In addition, we find important variation in the responses across firms: shareholders of firms in low-pollution industries and firms with primarily private ownership responded more negatively to award announcements. Furthermore, the peers of winning firms showed higher announcement returns than the award winners. Our results suggest that a key benefit of corporate environmentalism in China comes through building stronger relationships with government, and that otherwise the market generally discourages firms from environmental leadership.     

Abnormal returns before acquisition announcements: evidence from Europe

Acquisition announcements influence the stock price of target firms, providing an opportunity for insiders to obtain significant abnormal returns. We study the presence of positive abnormal returns before the announcement date, in target firms, quoted in Euronext markets (Belgium, France, The Netherlands and Portugal) from 2001 to 2007. We investigate whether the pre-announcement run-up of prices can be explained by rumours in the media and the percentage of capital previously owned by the bidding firm, among other factors. We examine cumulative abnormal returns in an event window of 60 days prior the acquisition announcement, with the event date adjusted for the previous disclosure of news about the acquisition, in the media. We compute a run-up index, and find that there are abnormal positive returns before the announcement date, confirming previous studies. We find that a significant part of the run-up is explained by: (i) market anticipation triggered by legitimate sources of information, namely, rumours in the media about the possibility of an acquisition bid and (ii) the percentage of capital previously owned in the target firm, by the bidding firm.     

Managerial Expectations of Synergy and the Performance of Acquiring Firms: The Contribution of Soft Data

This study examines whether the “soft” information present in merger and acquisition (M&A) announcement press releases contains incrementally valuable news relative to traditional “hard” data. Using the methodology of Loughran and McDonald [2011], we construct measures of synergy expectations and managerial optimism for more than 1,200 M&A announcements over the period 1995–2007. We find that synergy expectations are positively related to announcement period returns, longer-run performance, and the market's reaction to quarterly earnings announcements. Managerial optimism is insignificant for explaining a merger's subsequent performance. We conclude that the soft information contained in M&A announcements concerning synergy expectations can provide useful information to investors.     

中国企业海外并购失败了吗?

本文运用市场模型、FF3FM模型和事件研究的基本方法评估1994—2009年中国157个企业海外并购事件的短期和中长期绩效。结果显示,尽管外界对海外并购绩效看法各异,中国企业海外并购事件公告日的市场绩效明显为正,反映了市场对中国企业海外并购的正面评价。从中长期的角度上看,中国企业海外并购整体上取得了非负的超常回报率(Abnormal return),体现了政府"走出去"战略的胜利开局。考虑到行业绩效差异,本文运用Fix-to-fix控制组的方法对并购中长期绩效的决定性因素进行了多元回归分析,结果显示海外并购受益于人民币升值,国有企业的并购绩效明显差于民营企业,中国海外上市公司的绩效优于内地上市的公司。     

Deregulation, consolidation and banks efficiency in Singapore: Evidence from event study window approach and Tobit analysis

A three-year window analysis together with the Data Envelopment Analysis (DEA) approach is employed to investigate the effects of mergers and acquisitions on the Singapore banking groups’ efficiency. The results suggest that the merger has resulted in a higher Singapore banking groups’ mean overall efficiency. We do not find evidence of more efficient acquirers compared to the targets and that the acquiring banks’ mean overall efficiency tends to improve from the merger with a more efficient bank. The Tobit regression results suggest that bank profitability has positive impact on bank efficiency, whereas poor loan quality has negative influence on bank performance.

Chinese overseas M&A performance and the Go Global policy1

It is well known that government plays an important role in the business activities of Chinese firms. Less certain is the effect this influence has on the wealth of those firms’ shareholders. We contribute to the literature by analysing stock market reactions to announcements by Chinese firms of overseas mergers and acquisitions (OMAs). OMAs are of particular interest because there can exist a conflict between the interests of the public sector in acquiring overseas assets, and the interests of the private sector in maximizing shareholder wealth. Our main dataset consists of 213 observations of 157 OMA events that occurred between 1994 and 2009, using share market returns from the Shanghai, Shenzhen, Hong Kong and US markets. The aggregation of share price data across multiple markets, and the listing of firms in multiple exchanges, raise econometric issues for the standard event‐study methodology. To address these, we use a new, feasible generalized least squares (GLS) procedure developed by Gu and Reed (2012) . On the basis of an analysis using both aggregated and disaggregated samples, and of daily and cumulative abnormal returns, we find consistent evidence that (i) Chinese OMAs have not lowered the wealth of shareholders of Chinese acquiring firms, and (ii) shareholders of Chinese acquiring firms have not fared worse under under China's ‘Go Global’ policy of encouraging outward investment by Chinese firms.     

Open technology innovation activity and firm value: evidence from Korean firms

Despite the importance of Open Technology Innovation Activity (OTIA) for firm value, the literature investigating effects of OTIA announcements of developing country firms is not known in international academic circles. Our study using an event study approach examines the effects of OTIA (technology import and joint R&D) announcements of firms in Korea, one of the leading developing and highly innovative countries. We find that the announcements of OTIA produce positive average abnormal returns. Interestingly, unlike the prior studies on developed country firms, OTIA with firms in the homogenous industry leads to greater firm value than that involving firms in heterogenic industries. This implies an importance of a technological fusion with external firms in different industries for value of developing country firms. In addition, this article finds no home bias that a nationality of partner firms is not essential for the relation between OTIA and value of firms.     

Contagion and competitive effects of plan confirmation of reorganization filings: Evidence from the Taiwan Stock Market

This paper aims to examine the intra-industry effects of confirmation of a reorganization plan. Using unique Taiwanese data on announcements of reorganization confirmation, I find evidence that such announcements elicit positive stock price reactions for the announcing firms and negative stock price reactions for other firms within the same industry. Specifically, negative competitive effects dominate positive contagion effects for industry rivals in the context of the announcement of a reorganization confirmation. Moreover, a hybrid neuro-fuzzy model is constructed, where five industry- and firm-level inputs are considered, to investigate which rivals enhance their position and which do not. Results show that my model is consistent and stable, and is good at classifying both contagion- and competitive-effect candidates.     

How effective is European merger control?

This paper applies an intuitive approach based on stock market data to a unique dataset of large concentrations during the period 1990–2002 to assess the effectiveness of European merger control. The basic idea is to relate announcement and decision abnormal returns. Under a set of four maintained assumptions, merger control might be interpreted to be effective if rents accruing due to the increased market power observed around the merger announcement are reversed by the antitrust decision, i.e. if there is a negative relation between announcement and decision abnormal returns. To clearly identify the events' competitive effects, we explicitly control for the market expectation about the outcome of the merger control procedure and run several robustness checks to assess the role of our maintained assumptions. We find that only outright prohibitions completely reverse the rents measured around a merger's announcement. On average, remedies seem to be only partially capable of reverting announcement abnormal returns. Yet they seem to be more effective when applied during the first rather than the second investigation phase and in subsamples where our assumptions are more likely to hold. Moreover, the European Commission appears to learn over time.
