投資機會集合與公司會計政策選擇、經理人自願性揭露盈餘預測資訊之相關性研究

曹杏如 Unknown Date (has links)
本研究以公司資產帳面價值與市場價值的比率、股東權益市場價值和帳面價值的比率、盈餘價格比、每股盈餘成長率作為投資機會集合的替代變數。首先,控制公司規模、財務槓桿、資產報酬率,探討投資機會集合與公司會計政策選擇間之關係;另外,控制公司規模、股權結構,探討投資機會集合與經理人自願性揭露盈餘預測資訊間之關係。 本實證研究結果發現: 一、根據單變量分析結果 1. 公司資產帳面價值與市場價值比率、盈餘價格比與公司有無發行公司債呈正相關。 2. 公司資產帳面價值與市場價值比率、盈餘價格比與公司負債比率呈正相關。 3. 除資產重估價政策、存貨成本流程假設中的盈餘價格比與本研究預期之方向相同外,其餘顯著性變數均與本研究假說之預期方向不符。 4. 經理人有無自願性揭露盈餘預測資訊與公司股東權益市場價值與帳面價值比呈正相關;而與盈餘價格比呈負相關。 5. 經理人自願性揭露盈餘預測資訊之性質與公司股東權益市場價值與帳面價值比率、盈餘價格比均呈負相關。 二、根據多變量分析結果 1. 投資機會集合之替代變數均與公司會計政策之選擇無顯著關係。 2. 盈餘價格比與公司經理人有無自願性揭露盈餘預測資訊呈負相關。 3. 經理人自願性揭露盈餘預測資訊之性質與公司股東權益市場價值與帳面價值比率、盈餘價格比均呈正相關。 三、根據兩樣本平均數檢定 1. 發行公司債的公司其投資機會集合顯著低於未發行公司債的公司。 2. 自願性揭露盈餘預測資訊的公司其盈餘價格比顯著低於未自願性揭露盈餘預測資訊的公司。 3. 自願性揭露樂觀性盈餘預測資訊的公司其公司股東權益市場價值與帳面價值比率顯著低於自願性揭露悲觀性盈餘預測資訊的公司。 研究結論: 1. 投資機會集合較低的公司傾向發行公司債。 2. 投資機會集合較低的公司具有較高財務槓桿。 3. 投資機會集合與公司會計政策選擇間並無顯著之相關性。 4. 投資機會集合愈高時,經理人愈傾向自願性揭露盈餘預測資訊。 5. 投資機會集合與經理人自願性揭露盈餘預測資訊的性質具相關性;然而,根據多變量分析之結果:經理人自願性揭露盈餘預測之性質與公司股東權益市場價值與帳面價值比率、盈餘價格比均呈正相關,由此無法確知投資機會集合與經理人自願性揭露盈餘預測資訊的性質間之影響關係。 / This research provides evidence on the cross-sectional relation between firms'investment opportunities, their debt and compensation contracts, their size and financial leverage, and their accounting policy choices. In addition, this study examines whether firms'investment opportunity set is also predictably related to voluntary earning forecast disclosure decisions made by the firm. The research conclusions show as follow: 1. Firms that have lower investment opportunity set tend to finance with public debts. 2. Firms which have lower investment opportunity set have higher financial leverage. 3. Investment opportunity set is not obviously associated with their accounting policy choices. 4. Managers of firms that have higher investment opportunity set tend to voluntarily disclose earning forecast. 5. This study cannot find the effect between investment opportunity set and the nature of voluntary earning forecast disclosure.

私募宣告之資訊內涵

陸潤生 Unknown Date (has links)
本研究探討私募宣告事件之資訊內涵,以瞭解私募宣告事件對公司整體價值所造成之影響,進而探討影響私募宣告效果的可能因素,並比較具備投資機會組與不具備投資機會組之累積平均異常報酬。 實證結果發現以股東大會日為宣告日之私募股權宣告具有資訊內涵,而且宣告效果提早反應。影響私募宣告後累積異常報酬之因素包括價格壓力、投資機會、發行價格及資訊不對稱程度。股票流動性高、股價波動程度低、具備投資機會、發行價格高或資訊不對稱程度高時,私募宣告後之累積平均異常報酬會較高。在事件日前,無投資機會組比具備投資機會組有較高之累積平均異常報酬;在事件日之後,具投資機會組比無投資機會組有較高之累積平均異常報酬。 / This study examines the information content of private placement announcement to unveil its impact on firm value, explores the factors affecting the effect of private placement announcement, and compares the market performance of firms with investment opportunities and those without investment opportunities. The results indicate that the information content of private placement announcement exists with early information leakage. Firms with higher stock liquidity, lower stock price variation, more investment opportunity, higher subscribed price or higher degree of information asymmetry will have higher cumulative average abnormal returns after the announcement. The cumulative average abnormal returns of companies without investment opportunity are higher than those with investment opportunity before the announcement date.
