董事會特性與年報自願性揭露關係之研究

金志遠, Chin, Chih-Yuan Unknown Date (has links)
由87年度爆發的數起地雷股事件(如國產汽車、東隆五金)中,可以發現產生問題的公司皆是在董事長主導公司的營運之下,最後發生掏空公司資產的情形,顯示目前公司法及證期會設計的監管機制,並未能發揮預期的監督功能。 監管機制設計的主要目的,係在防範經營者追逐私利而非公司最大利益的情形發生,故要使監管機制有效運作,必須增加資訊的揭露予股東或其他利害關係人,以解決資訊不對稱的問題。而年報中的自願性揭露就是解決強制性揭露下監督者資訊不足的方式之一。故本研究欲從監管的角度切入,由公司所有權結構及董事會特性,探討影響公司自願性揭露水準的因素,以幫助年報使用者藉由公司監理特性或自願性揭露水準,判斷公司監理機制的運作是否良善,並提供主管機關,於未來修定公司監理層面及年報揭露的相關規定時,得以參考的資訊。 本研究由公司所有權結構及董事會之特性著手,探討可能影響公司年報自願性揭露的七個因素:1.是否為家族企業,2.是否有監管機制存在,3.董事會成員持股比例,4.董事會成員持股質押成數,5.董事會規模,6.最大家族占董事席次比例,7.獨立法人占董席次比例。其中,家族企業的判斷採用Cubbin & Leech (1983)表決機率模型算得之臨界持股比例,家族持股超過該臨界比例者始視為家族企業。監管機制則以獨立法人的持股及董事會中是否有獨立法人或以外的第二勢力存在來衡量。 本研究首先設計一揭露索引表做為揭露水準的衡量表,並將樣本公司年報內容比對索引表內的揭露項目,採取加權的方式進行評分。索引表內的項目共分五大類:背景資訊、歷史結果彙總、非財務性統計資訊、預測性資訊及管理人員討論與分析。研究對象則為民國87年之上市公司,並排除金融保險業及公民事業民營化的公司。 實證結果顯示: 1、獨立法人持股比例與董事會中獨立法人第二勢力的存在,與揭露總分間呈顯著正相關,表示公司在有監管機制之下,其揭露水準確實較無監管機制者為佳。此外,家族占董事席次比例與揭露總分間呈顯著負相關。而前三大會計師事務所較非前三大會計師事務所更能發揮專業的影響力,故能增加公司年報中的自願性揭露。至於其他變數對於自願性揭露水準的影響則不如預期。 2、家族企業的揭露水準並未如預期較非家族企業為差,此可能與台灣家族企業普遍存在,形成家族企業間的競爭局面有關。而經實證得知,當家族企業的持股至一高水準時,由於與公司間利益密切結合,更有積極經營的企圖心,故將增加年報中的自願性揭露,以爭取投資人的認同。 3、年報揭露水準於產業間亦存在著差異。於資料搜集的過程中發現,屬於相同產業的公司,揭露內容多有相似的模式。而實證研究亦發現,塑膠業、電子業的揭露水準較其它產業為高,營建、百貨業的揭露水準則較其它產業為低。

經理人性別差異與自願性盈餘預測關聯性之研究 / Gender difference and management earnings forecasts

邱逸婷 Unknown Date (has links)
本文旨在探討經理人性別差異與自願性盈餘預測之關聯性,即公司經理人性別是否會對其自願性盈餘預測偏差性及自願性盈餘預測準確度造成影響。由過去有關性別差異之研究可發現女性具有規避風險、保守行事…等特點,故本研究欲探討經理人性別差異對自願性盈餘預測之影響。實證結果發現:女性經理人進行自願性盈餘預測時,盈餘預測值較保守。相反的,男性經理人進行自願性盈餘預測時,盈餘預測值則較具樂觀性。再者,當公司經理人性別為女性時,自願性盈餘預測準確度較高。 / In this thesis, I explore the association between gender differences and the management earnings forecasts. Prior studies show that, in general, women are more risk adverse and act more ethically than man. Therefore, I examine whether the gender of management affects the bias and accuracy of management earnings forecasts. Consistent with my predictions, the results show that female CEOs release more conservative forecasts than their male CEOs counterparts. Moreover, I also find that female CEOs issue less accurate earnings forecasts compared to male CEOs. Overall, this study provides evidence that there are the relationship between gender difference and the bias of management earnings forecasts.

自願性揭露下管理當局盈餘預測準確度決定因素之研究 / Determinants of Accuracy of Discretionary Management Forecasts of Earnings

張希恭, Chang, Peter Unknown Date (has links)
本研究係探討在自願性揭露的情況下,公司盈餘預測準確度會受那些因素的影響?對國內外相關文獻及我國股市資訊環境進行探討後,提出預測期間長短、公司規模大小、盈餘變異性、市場風險、行業別、上市期間長短、自有資本比、綜合槓桿效果、揭露次數多寡、公告媒體別、揭露後累積異常報酬、上市類別、高估低估、預測階段以及年度別等可能影響準確度之因素,利用迴歸分析,以橫斷面(cross-sectional design)之設計方法,來探討各自變數與因變數(盈餘預測準確度)間之關係。   依理論判斷所制定之選樣標準,本研究以117家上市公司對於民國78年度至83年度之盈餘預測資料,共941個觀察值為研究樣本。經嚴格理論建立與統計分析后,本研究得出以下的結論:   一、預測期間愈短、管理當局盈餘預測準確度愈高。   二、公司規模愈大,管理當局盈餘預測準確度愈高。   三、市場風險愈低,管理當局盈餘預準確度愈高。   四、行業別與預測準確度具有關係。   五、自有資本比愈高,管理當局盈餘預測準確度愈高。   六、揭露次數愈多與管理當局盈餘預測準確度具有關係。   七、媒體別與預測準確度具有關係。   八、上市第一類股,預測準確度較高。   九、預測階段與預測準確度具有關係。

高研發企業主動揭露預測性非盈餘及智慧資本資訊行為之研究

崔琇玫 Unknown Date (has links)
本研究以1997至2001年國內高研發密度之上市上櫃公司為研究對象,探討高研發密度公司揭露非盈餘以及智慧資本相關資訊之行為。首先探討企業揭露資訊之偏好及趨勢,再分析影響企業揭露非盈餘及智慧資本資訊頻率之因素,並探討企業股價與帳面價值間之差異及股票週轉率與企業揭露智慧資本相關資訊之關聯性。 實證結果發現,公司主動揭露與盈餘有關資訊之頻率有逐年下滑的現象,而揭露非盈餘及智慧資本相關資訊的頻率則有逐漸升高的趨勢。以分組檢定結果而言,未預期盈餘為正且幅度較大的公司在揭露智慧資本資訊方面顯著較未預期盈餘為負且幅度較大的公司積極。就影響企業揭露非盈餘以及智慧資本相關資訊之因素而言,未預期盈餘、員工每人營業利益、研發密集度,以及每人配備率與揭露非盈餘及智慧資本相關資訊之次數均呈顯著正向關係,而董監事持股比率以及用人費用率則與兩項資訊之揭露次數呈顯著負相關。 此外,屬於資訊電子業以及規模較大的公司,揭露非盈餘及智慧資本相關資訊之意願較強。就企業股價與帳面價值之差異以及股票流動性而言,資訊電子業之股價淨值比及股票週轉率均較非資訊電子業為高,策略聯盟(流程資本)資訊揭露次數與股價淨值比呈顯著正(負)向關係,新產品及策略聯盟(人力資本)資訊揭露次數則與股票週轉率呈顯著正(負)相關。 關鍵字:自願性揭露、智慧資本、市價淨值比 / Based on a sample of firm listed on TSE, this thesis investigates the voluntary disclosure behavior ofR&D intensive companies in Taiwan over the period of 1997 to 2001. With an emphasis on non-earnings and intellectual capital-related disclosure policies, we first explore the disclosure behavior in terms of frequency and type of information revealed by management. We then examine whether price-to-book (P/B) ratio and stock turnover ratio reflect the disclosure of non-earnings and intellectual capital-related information. The empirical results suggest a declining trend in disclosing earnings information, with an opposite tendency in non-earnings information over the period examined. In addition, unexpected earnings and variables proxy for intellectual capital determine the disclosure behavior of non-earnings and intellectual capital-related information. Firms with operating performance far beyond market's expectation tend to disclose more intellectual capital-related information than firms with operating performances far worse than market has expected. Variables such as operating income per employee and cost of human resource (proxies for human capital), R&D intensity (proxy for innovation capital), equipment per employee (proxy for process capital) as well as the ratio of directors' shareholding are found to be significantly related to the disclosure frequency of non-earnings and intellectual capital-related information. The findings also indicate that electronics and software industries are more likely to disclose more non-earnings and intellectual capital-related information and have higher price-to-book and stock turnover ratios as compared to other industries in the sample. Firms disclose more (less) strategic alliance (process capital) information is found to have higher price-to-book ratios. Firms disclose more (less) strategic alliance and new product (human capital) information is found to have higher stock turnover ratio. It appears that more disclosure on intellectual capital-related information does not necessarily and monotonously explain the variation in both price-to-book and stock turnover ratios. Key words: voluntary disclosure, intellectual capital, price-to-book ratio, stock turnover ratio

投資人情緒與法人說明會關聯性之研究 / Investor sentiment and conference calls

吳博翀, Wu, Po Chung Unknown Date (has links)
本文旨在探討投資人情緒與法人說明會之關聯性,即公司如何經由召開法人說明會,策略性地回應投資人情緒反應,以企圖影響情緒所導致的預期偏差。實證發現:管理當局策略性地改變其自願性揭露政策,以反映投資人情緒。當投資人情緒愈低落時,公司將傾向於召開法人說明會,且公司召開法人說明會之頻率亦會增加。相反的,當投資人情緒高昂時,公司則愈不會召開法人說明會。再者,當投資人情緒愈低落時,法人說明會所揭露之公司資訊將愈樂觀。此研究亦顯示公司自願性揭露政策的選擇,反映管理當局渴望維持樂觀之評價。 / In this paper we explore the association between investor sentiment and the likelihood of holding conference calls. In other words, this paper investigates how firms react strategically to investor sentiment via their conference calls in an attempt to influence the sentiment-induced biases in expectations. We show that managers strategically vary their voluntary disclosure policies in response to prevailing sentiment. We find that during low-sentiment periods, the firms are more likely to conduct conference calls and conduct them more frequently; while during periods of high sentiment they decrease the frequency of conference calls. In addition, during low-sentiment periods, the conference calls disclose more optimistic information. Overall, this study provides evidence that company’s voluntary disclosure choices reflect managers desire to maintain optimistic valuations.
