Information asymmetry and accounting restatement: NYSE-AMEX and NASDAQ evidence

We examine the impact of accounting restatement announcement on firms’ value and information asymmetry for both auction market (NYSE-AMEX) and dealer market (NASDAQ) using a public sample of restatement announcements from 1997 to 2005. In both markets, we document economically and significantly negative mean cumulative abnormal returns around the announcement dates. The restatements attributed to auditors are associated with more negative returns than those attributed to management and the SEC. However, there is no significant difference between market reactions arising from the core and non-core restatements. We also find a significant increase in volume, number of transactions, average order size, volatility, and various measures of spreads after the restatement announcement indicating that restatement announcements diminish company prospects and contribute to increased uncertainty and information asymmetry. Finally, we find that the information asymmetry in the NASDAQ market around the event date is less pronounced than in the NYSE-AMEX market.     

Relationship Between Analyst Forecast Properties and Equity Bid‐Ask Spreads and Depths Around Quarterly Earnings Announcements

Abstract:   We study the relationships between three variables which proxy for the ex‐ante level of information asymmetry – forecast dispersion, forecast revision volatility, and the level of analyst coverage, and equity bid‐ask spread and depth changes around quarterly earnings releases. Kim and Verrecchia (1994) suggest that earnings releases increase the level of information asymmetry and lower the level of liquidity in the security market. Using both an OLS regression framework and a simultaneous equations model, we examine whether equity bid‐ask spreads increase and depths decrease as the level of information asymmetry increases. Our results indicate that spreads are higher (relative to a non‐event period) around earnings announcements when information asymmetry is more pronounced; however, depths are lower only on the day following the announcement when there is greater information asymmetry. Relative spreads have a significant positive relation with both forecast dispersion and revision volatility and a significant negative relation with analyst coverage. Relative depths have a significant negative relation with forecast dispersion and a significant positive relation with analyst coverage. Our findings indicate that the equity specialist adjusts both spreads and depths when confronting informed traders around earnings releases and that these adjustments are more pronounced when the level of information asymmetry is greater.     

Information asymmetry around operational risk announcements

Operational risk incidences are likely to increase the degree of information asymmetry between firms and investors. We analyze operational risk disclosures by US financial firms during 1995–2009 and their impact on different measures of information asymmetry in the firms’ equity markets. Effective spreads and the price impact of trades are shown to increase around the first announcements of such events and to revert after the announcement of their settlement. This is especially pronounced for internal fraud and business practices related events. Market makers respond to higher information risk around the first press cutting date by increasing the quoted depth to accommodate an increase in trading volumes.The degree of information asymmetry around operational risk events may be influenced by the bank’s risk management function and the bank’s governance structure. We indeed find that information asymmetry increases more strongly after events’ first announcements when firms have weaker governance structures—lower board independence ratios, lower equity incentives of executive directors, and lower levels of institutional ownership. In contrast, the firms’ risk management function has little to no impact on information asymmetry. We interpret this as evidence that the risk management function is primarily driven by regulatory compliance needs. The results of this study contribute to our understanding of information asymmetry around operational risk announcements. They help to shed light on the role that regulation and corporate governance can play in order to establish effective disclosure practices and to promote a liquid and transparent securities market.     

Daily Closing Inside Spreads and Trading Volumes Around Earnings Announcements

This paper examines the determinants of inside spreads and their behaviour around corporate earning announcement dates, for a sample of UK firms over the period 1986–94. The paper finds that closing daily inside spreads are affected by order processing costs (proxied by trading volumes), inventory control costs (trading volumes and return variability) and asymmetric information (unusually high trading volumes). Inside spreads start to narrow 15 days before an earnings announcement, and narrow further by the end of the announcement day. We also identify a puzzling phenomenon. There is only a 'sluggish' recovery of spreads after the announcement: inside spreads continue to remain at relatively narrow levels, and take up to 90 days to recover to their pre–announcement width.     

Shareholder wealth effects of rights issues: Evidence from the New Zealand capital market

This study examines security price reaction to the announcement of rights issues by New Zealand firms between 1976 and 1994. Over this period, price reaction to rights issue announcements in New Zealand was significantly negative. The price reaction to the announcement was more negative for underwritten compared to non-underwritten rights issues. The evidence suggests non-underwritten rights issues have higher expected participation in the issue by existing shareholders. The results are broadly consistent with the adverse selection cost arguments of Eckbo and Masulis [Eckbo, B.E., Masulis, R.W., 1992. Adverse selection and the rights offer paradox. Journal of Financial Economics 32, 293–332] and help further explain the rights offer paradox whereby firms in a small capital market, like New Zealand, continue to rely on rights issues to raise new equity. Price reaction to the rights issue announcement was also more negative the larger the relative issue size. This result supports both the adverse selection cost and information asymmetry arguments of Krasker [Krasker, W.S., 1986. Stock price movements in response to stock issues under asymmetric information. Journal of Finance 41, 93–105] and the signaling framework hypothesis of Miller and Rock [Miller, M.H., Rock, K., 1985. Dividend policy under asymmetric information, Journal of Finance 40, 1031–1051].     

Volatility spreads and earnings announcement returns

Prior research documents that volatility spreads predict stock returns. If the trading activity of informed investors is an important driver of volatility spreads, then the predictability of stock returns should be more pronounced during major information events. This paper investigates whether the predictability of equity returns by volatility spreads is stronger during earnings announcements. Volatility spreads are measured by the implied volatility differences between pairs of strike price and expiration date matched put and call options and capture price pressures in the option market. During a two-day earnings announcement window, the abnormal returns to the quintile that includes stocks with relatively expensive call options is more than 1.5% greater than the abnormal returns to the quintile that includes stocks with relatively expensive put options. This result is robust after measuring volatility spreads in alternative ways and controlling for firm characteristics and lagged equity returns. The degree of announcement return predictability is stronger when volatility spreads are measured using more liquid options, the information environment is more asymmetric, and stock liquidity is low.     

Independently Certified Industry-specific Disclosures to the Capital Market: The JORC Code in the Australian Mining Industry

We investigate compliance with the Australian JORC Code for reporting mineral resources and ore reserves, the quality of the disclosure, and its impact on the capital market. The compliance and quality assessment is conducted by two experienced geologists who find that while the overall reporting quality improved after the 2012 revisions to the Code, they disagree on the extent of improvement. This reflects the uncertainties involved and the difficulty in interpreting the reports. Both geologists agree that the greatest improvement is seen in early-stage projects, consistent with the expectation that there are more uncertainties surrounding these, and the additional information disclosed under the 2012 JORC Code appears to assist in reducing the uncertainties to some extent. The capital markets study shows that JORC announcements have a significant impact on investors’ assessments of firm value, and that the announcement impact is higher after the 2012 revisions designed to strengthen the disclosure requirements. This is consistent with post-2012 JORC reports conveying higher information content. There continues to be information leakage prior to announcement date. Further tests show a widening of bid–ask spreads in the post-2012 period, suggestive of higher information asymmetry. While the probability of informed trading declines for large firms, it remains statistically unchanged for the rest of the sample. The findings reiterate the need for regulators and standard setters to be cognisant of unintended consequences of their decisions. The substantiation process under JORC involves a delay in the release of ‘news’, a ‘chilling’ effect with larger announcement effects.     

The Role of the Business Press as an Information Intermediary

This paper investigates whether the business press serves as an information intermediary. The press potentially shapes firms' information environments by packaging and disseminating information, as well as by creating new information through journalism activities. We find that greater press coverage reduces information asymmetry (i.e., lower spreads and greater depth) around earnings announcements, with broad dissemination of information having a bigger impact than the quantity or quality of press-generated information. These results are robust to controlling for firm-initiated disclosures, market reactions to the announcement, and other information intermediaries. Our findings suggest that the press helps reduce information problems around earnings announcements.     

Information Asymmetry and the Dealer's Bid-Ask Spread: A Case Study of Earnings and Dividend Announcements

Recent theoretical work on the bid-ask spread asserts that the dealer should widen the bid-ask spread when he or she suspects that the information advantage possessed by informed traders has increased. Thus, the dealer's spread can be employed to test for an increase in information asymmetry prior to an anticipated information event. In this paper, the method is applied to earnings and dividend announcements, which have been documented to be information events. The authors study three groups of announcements: (a) joint announcements—i.e., earnings and dividend announcements that are made on the same day, (b) initial (first) announcements—earnings or dividend announcements that were not preceded by another announcement in the prior thirty days, and (c) following (second) announcements—those announcements that follow the first announcement by at least ten days but by no more than thirty days. The authors find a strong increase in information asymmetry only before the second announcements and virtually no increase before the joint and first announcements. This is consistent with the hypothesis that there is, on average, normal information asymmetry before announcements, but that the dealer will suspect a nonroutine announcement (with an attendant increase in information asymmetry) when the second announcement is separated from the first by more than ten days. Other possible explanations for the results are discussed, and suggestions for future research are outlined.     

Trading Volume, Information Asymmetry, and Timing Information

This paper investigates trading volume before scheduled and unscheduled corporate announcements to explore how traders respond to private information. I show that cumulative trading volume decreases inversely to information asymmetry prior to scheduled announcements, while the opposite relation holds for volume after the announcement. In contrast, trading volume before unscheduled announcements increases dramatically and shows little relation to proxies for information asymmetry. I investigate the behavior of market makers and find that they act appropriately by increasing price sensitivity before all announcements, implying that they extract timing information from their order books.     

Trading Activity,Trade Costs and Informed Trading for Acquisition Targets and Acquirers

Abstract

Microstructure effects of tender offer acquisitions on targets and acquirers differentiated by listing venue and payment method are examined. Trading activity increases more for targets than for acquirers upon offer announcement. Investors are more likely to sell targets upon announcement using direct market orders against ask limit orders for cash payment offers. While target liquidity improves as spread costs fall and quoted depths increase, acquirer liquidity falls continuously to successful offer completion. Due to increased trading differences, temporary trade costs fall more for targets than for acquirers. Permanent trade costs decline over the tender offer cycle for both parties, and especially for targets for cash tender offers and for acquirers for shares tender offers. The probability of informed trading declines (remains constant) for targets (acquirers) because increased trading intensity is greater (the same) for uninformed versus informed traders. As expected, abnormal returns and changes in own-firm permanent return volatility are negatively (but weakly) and positively (and strongly) related, respectively, to changes in information asymmetry upon announcement.     

The informativeness of pro forma and street earnings: an examination of information asymmetry around earnings announcements

Using adverse-selection cost as a proxy for information asymmetry, we find evidence that non-GAAP earnings numbers issued by management (pro forma earnings) and analysts (street earnings) improve price discovery. First, information asymmetry before an earnings announcement is positively associated with the probability of a non-GAAP earnings number at the forthcoming earnings announcement. Second, the post-announcement reduction in information asymmetry is greater when managers or analysts issue non-GAAP earnings at the earnings announcement and when the magnitude of the non-GAAP earnings adjustment is larger. Our results suggest that earnings adjustments by analysts and managers increase the amount and precision of earnings information and help to narrow information asymmetry between informed and uninformed traders following earnings announcements. Alternatively, the findings may be attributable to characteristics of non-GAAP firms and overall better reporting quality for those firms rather than non-GAAP earnings disclosure per se.     

Adverse Information and Dealer Spreads: Evidence from Dutch Auction Repurchases

The Dutch auction repurchase has become an increasingly popular alternative to open market repurchases and self-tender offers for the distribution of earnings to shareholders. In a Dutch auction, the repurchase price is not determined by a managerial decision, but by shareholders. The extent to which a Dutch auction signals private information is tested by examining stock returns and bid-ask spreads. Stock prices increase and bid-ask spreads widen during the announcement of a Dutch auction; prices decrease and spreads narrow at expiration. Because of the uncertainty surrounding the final repurchase price, Dutch auctions initially increase the risk to which security dealers are exposed. As information asymmetry among managers, investors, and dealers is reduced at expiration, security dealers no longer need to protect themselves from information trades.     

Underpricing,Share Overhang,and Insider Selling in Follow‐on Offerings

Prospect and information‐momentum theories predict that insiders can offer fewer shares in an initial public offering (IPO) to create informational momentum and obtain higher prices in follow‐on offerings. I find that dilution and insider participation in the IPO are negatively related to the number and size of follow‐on offerings, consistent with the prediction. However, insider selling in follow‐on offerings is positively related to IPO selling, contrary to the theories. Returns around follow‐on offering announcements are more negative for newly public firms than older firms, but for newly public firms do not differ by whether the announcement comes before or after the lockup expiration date.     

Partial anticipation, the flow of information and the economic impact of corporate debt sales

Corporate debt sales have been regarded as 'no news' eventsbecause there is no significant price reaction on average totheir announcement. We explore the hypothesis that this lackof average price reaction to debt sale announcements is explainedby the partial anticipation of debt offers. Theory suggeststhat the demand for debt capital is fundamentally related tochanges in the sources and uses of funds, and we find evidencethat earnings are significantly lower, investment growth issignificantly bigger, and, for some issuers, debt refundingrequirements are significantly greater in the period immediatelyprior to issue than in periods well before and after the issue.We find that this preissue information conditions investors'expectations of issue, thereby affecting the cross-sectionalannouncement date price reaction to debt sales in two ways.First, announcement date price reactions are negative, on average,for unanticipated offers or for those offers where prior informationsuggests that an issue is unlikely. Second, holding the probabilityof issue constant, announcement date price reactions are significantlymore negative for offers that raise more capital than investorsexpected. These results are consistent with cash flow signalingand asymmetric information models of corporate financings.     

Speculation spreads and the market pricing of proposed acquisitions

This paper examines speculation spreads following initial acquisition announcements in 362 cash tender offers spanning the 1981–1995 period. Speculation spreads in acquisitions, defined as the percentage difference between the bid price and market price one-day after the initial announcement, are the starting point for arbitrage returns, a subject receiving increased attention in practice and in the literature. Speculation spreads exhibit a positive mean, with considerable cross-sectional variation. In fact, over 23% of speculation spreads are negative, indicating a post-announcement price greater than the initial bid price. In spite of its importance, the informational content of the speculation spread and the reasons for its cross-sectional variation have not been previously examined. We model speculation spreads as the visible component of total speculative returns of the target. Rational traders set speculation spreads anticipating the expected price resolution and length of the acquisition bid. Empirically, we find strong support for key implications of our model. Speculation spreads are significantly related to bid and offer characteristics observable ex ante. Consistent with our model, they are also significantly negatively related to the magnitude of price revision and significantly positively related to offer duration. These results are robust to the inclusion of bid and offer characteristics known ex ante as well as those only revealed ex post. The results are consistent with market pricing of both offer duration and price resolution at the time of the initial announcement.     

Information Asymmetry and Valuation Effects of Debt Financing

This study demonstrates that under conditions of information asymmetry, shareholders earn positive returns around the shelf registration date of straight debt. The results provide evidence to support Miller and Rock's conclusion that new expected financing by firms can result in positive returns to shareholders and Blazenko's contention that positive returns around the announcement date of straight debt issuance may be found by studying firms with asymmetric information. Firms with reported research and development expenses are assumed to have a higher level of asymmetric information and a greater chance of requiring new outside financing. Research and development expense intensity and abnormal earnings in future periods are found to be significant in a cross-sectional regression explaining abnormal returns for days surrounding the announcement period.     

Information uncertainty,information asymmetry and corporate bond yield spreads

This study examines the effects of information uncertainty and information asymmetry on corporate bond yield spreads using American data from 2001 to 2006. Empirical results of this study show that investors charge a significant risk premium for both information uncertainty and information asymmetry when controlling for variables well known in the literature. The results are robust even when controlling for credit ratings. Finally, information uncertainty and asymmetry help structural-form credit models explain the yield spreads of bonds with short maturities.     

INTRADAY CHANGES IN TARGET FIRMS' SHARE PRICE AND BID-ASK QUOTES AROUND TAKEOVER ANNOUNCEMENTS

This paper documents changes in share prices, bid-ask spreads, and quote sizes for target firms during the day a takeover proposal is announced. The mean 21.2 percent announcement-day return consists primarily of a 19.5 percent return at the announcement. There is little evidence that spreads increase before the announcement, except when trading is suspended because of an order imbalance. Quote sizes show some sign of decreasing just before the announcement. The quoted bid-ask spread and size increase immediately after the announcement, but spreads quickly return to normal.     

Management Quality and Equity Issue Characteristics: A Comparison of SEOs and IPOs

We use hand-collected data on the management quality of firms making seasoned equity offerings (SEOs) or initial public offerings (IPOs) to analyze the relationship between management quality and equity issue characteristics, and to compare the effect of management quality on SEOs versus IPOs. We hypothesize that higher quality managers are more credible to equity market investors, thereby reducing the information asymmetry they face in the market and outsiders’ information production costs. Therefore, the equity issues of higher management quality firms will have more reputable underwriters, smaller underwriting spreads, and other expenses, and smaller SEO discounts. Further, since better managers will be able to select better projects, higher management quality firms will have larger offer sizes. Finally, since SEO firms are likely to suffer from less information asymmetry compared to IPO firms, these effects will be smaller for SEOs than for IPOs. Our findings support the above hypotheses. Our direct tests of the relationship between management quality and information asymmetry, and our comparison of information asymmetry in SEOs versus IPOs provide further support for these hypotheses.
