隨著國際化的發展，企業為降低財務報表重編的相關成本，採用全球統一的財務會計準則已成趨勢。近年來，我國之財務會計準則委員會陸續修訂了若干公報，其中之一為第十號公報。該公報修訂至生效時期，正值全球金融風暴。因此，政府對實施該公報的時機決策反覆，而企業界、會計界及媒體皆對該公報相當關注。 本研究旨在探討新十號公報對整體市場、各產業及不同特性公司之影響。本研究採用事件研究法，以似乎不相關迴歸模式，分析我國公司在該公報修訂期間及政府實施決策期間之股票累積平均異常報酬率。 研究結果指出，在新十號公報修訂期間，市場對該公報的反應較為負面；在政府政策反覆期間，市場反應則有正有負。各產業部份，電子業於該公報修訂初期受影響較大，推論原因為電子業固定成本高、毛利較低之緣故；而在該公報政府實施決策階段則受影響較小，推論原因為大部分電子業公司均做好因應措施。公司特性部分，大公司對該公報愈持正面態度；老公司則較排斥該公報；前三年度虧損的公司，受該公報影響較小；而成長機會較多之公司，在該公報制定初期受影響較大，但於政府實施決策階段反而受影響較小。 / To pursue globalization, it has been a trend for firms to gradually adopt the International Accounting Standards; that would help reduce the costs related to cross-border restatement of financial reports. To converge with the International Accounting Standards, the Financial Accounting Standards of Taiwan has been revised in recent years. One of the revised standards is the new SFAS No. 10. That revision took place amid the financial crisis. Before the new standard became effective, the government in Taiwan swung on the timing issue of formal adoption. As a result, firms, practitioners, and the media all paid close attention to the new SFAS No. 10. This study aims to examine the revision and adoption decision effects of the new SFAS No. 10 on the stock market, industries, and firms. Firm characteristics that could be factors of the reaction were also examined. This research is an event study using seemingly unrelated regression to analyze the accumulated average abnormal returns of stocks of listed companies in Taiwan. The empirical results are as follows. First, the whole market mostly reacted negatively in the standard revision period and in either way during the standard adoption decision period. Next, in the standard revision period, the electronic industry also reacted negatively, as it would be more affected because of its higher fixed cost and lower gross profit. Yet, in the adoption decision period, the electronic industry was less affected likely because most electronics firms were ready for adoption. Thirdly, as to firm characteristics, bigger firms were willing to adopt the new standard, but older firms were not so. In addition, firms that had losses in the previous three years were less affected by the new standard. Finally, firms that had greater growth opportunities were more affected in the early period of standard revision but became less affected in the adoption decision period.

本研究主要探討台灣半導體產業供應鏈上游公司召開法人說明會是否會影響中下游公司之股價。本研究將法人說明會公布之資訊區分為財務資訊及非財務資訊，除探討財務資訊對供應鏈中、下游公司股價是否具影響效果外，亦探討財務及非財務的法人說明會資訊是否具有增額效果。實證結果顯示財務資訊在法人說明會召開前後一天與累積異常報酬呈現顯著正向關係，但非財務資訊卻呈現顯著反向關係，顯示非財務資訊會修正財務資訊所造成之效果。另外，資訊於供應鏈中移轉之距離越長，則移轉效果會越小，但若單純為好消息或壞消息，則移轉效果將增強。 / This research examines the influence of conference call information on the stock price of supply chain partners. The semi-conductor industries in Taiwan were used in this paper to examine the issue. I examined two kinds of information disclosed from conference calls: financial information and non-financial information. I first examined the information contained in conference calls for any effects on supply chain partners. Furthermore, I also examined to see if the non-financial information contains any additional effects to the supply chain partners. The empirical results show that the accumulated abnormal return of the supply chain partners is significantly positive related to the financial information around the conference call date. The accumulated abnormal return of the supply chain partners is significantly negative related to the non-financial information around the conference call date. The results show that both financial and non-financial information would influence the accumulated abnormal return of supply chain partners. The non-financial information contains additional information that revises the influence of the financial information.

本文以2003到2006年美國上市之不動產投資信託（REITs）的資產稅賦遞延交換做研究，並用資產出售交易作為比較，觀察稅賦遞延交換對股票報酬和股利的影響，研究結果發現稅賦遞延交換對於股票報酬有負的宣告效果，然而出售資產的交易有正的且顯著的宣告效果，由於美國REITs基於稅法規定，作為免稅體，每年要以股利的形式分配百分之九十的盈餘給股東，稅賦遞延交換並不能像資產出售交易一樣帶來現金流入，因此對於未來股東的股利所得有所影響，股東對於股票報酬沒有正向的反應，但是股東會考慮稅賦遞延交換會帶來資產重配置的效率，再加上REITs通常會支付比規定還要多的股利，因此稅賦遞延交換的對於股票報酬的負影響會因此而減弱，進一步針對交易方式還有REITs股利分配進行研究，研究的結果支持稅賦遞延交換後的股利比起直接出售交易後所發放的股利還要少。本文除了研究股東對於交易宣告的反應之外，也綜觀不同資產交易方式的現金流量和REITs股利的關連性，藉此瞭解影響REITs選擇交易方式的內涵因素，以及對股票報酬和股利的影響。 / This research examines the tax deferred exchanges made by public U.S. Real Estate Investment Trusts (REITs) over 2003-2006 as well as the transactions of sell-off. The purpose of this study attempts to explore the effects of tax deferred exchange on stock returns and dividend distribution. Result of this study shows that announcement effect of tax deferred exchange is negative in stock value. On the contrary, the relationship between sell-offs and stock value is significantly positive. The reason to explain the difference on announcement effect between two types of property transaction is the specific taxable earning distribution restriction on REITs. U.S REITs have to pay out 90 % of taxable earnings in the form of dividends to their shareholders to exempt from tax. As a result, tax deferred exchange doesn’t bring cash inflow contributing to dividend increase and then shareholders react a lower stock return on tax deferred exchange than on sell-offs. However, the negative effect is weakened by the efficiency of asset reallocation and the regular dividend distribution over tax law restriction. In the analysis of dividend payment, the result of dividend examination supports the hypothesis that tax deferred exchange without cash inflow make dividend fewer than sell-offs. This study may be of importance in explaining the reaction of shareholders on tax deferred exchange of REITs’ property, as well as in providing shareholders with a better understanding of the relationship between cash flow and dividend distribution in order to clarify the cause that affect REITs to utilize different types of transaction and the factors that affect stock return and dividend.
