The regulatory framework of many countries allows the upward revaluation of assets. Previous studies on the association of asset revaluation and future performance in Australia (Barth and Clinch, 1998), U.K. (Aboody, Barth and Kasznik, 1999) and Hong Kong (Jaggi and Tsui, 2001) have shown that upward asset revaluations are positively associated with the firm’s operating performance, suggesting that asset revaluations are value relevant. This study extends the previous research by focusing on the New Zealand environment with recent data to examine the association of upward asset revaluation and future operating performance. There is no obvious evidence indicating that upward revaluations are associated with operating performance in New Zealand. Our market assessments show that current year asset revaluations are related to share prices and returns, but are not statistically significant.

本研究的目的在探討，盈餘中所包括的由營業而來的運用資金及現金流量相對於盈餘而言，是否具增額資訊內涵？動機來自於我國於民國78年12月28日公布現金流量表取代財務狀況變動表，前者之主要衡量指標為營業活動現金流量，後者則為營業而來之運用資金，而以前者取代後者的理由究竟是因營業活動現金流量較營業而來運用資金更具資訊內涵？抑或是營業而萊的運用資金與盈餘之相關性太高，導致該指標無增額資訊內涵，而須提供與盈餘相關性較低的現金流量資訊？還是財務狀況妥動表相對於損益表及現金流量表而言，已無法提供增額資訊內涵？由於相關研究結果分歧，故本論文試圖做一深入瞭解。 本研究採事件研究法(Event Study)，藉由橫斷面分析，透過四階段進行測試：第一階段比較營業而來的運用資金及營業活動現金流量之相對資訊內涵；第二階段則加入稅後盈餘，測試第一階段之自變數相對於稅後盈餘而言，是否具增額資訊內涵，至於測試方法則採用可能比例測試法(Liklihood Ratio Test)，測試全迴歸模式中，某一特定變數的估計值是否異於零的方式；第三階段則將異積異常報酬(CAR)分成高、中、低三組，重新檢視一、二階段之結果，看是否在三組間能獲得相同的結論。最後則測試重大非營業項目及土地重估增值之增額資訊內涵。 本研究以162家國內上市製造業為樣本，蒐集其民國八十年至八十四年之財務資料進行實證研究，獲致以下結論： 一、營業而來的運用資金及現金流量相對資訊內涵之比較以年度資料及Pooling結果觀之，除民國80年之營業而來運用資金及營業活動現金活動與股票報酬有顯著關聯性外，其餘年度（包括pooling）則否，故無法得出年度之一般化結論。但若將累積異常報酬之pooling結果依大小分為三組，結果發現高報酬組中，營業而來的運用資金與股票報酬關聯性大於營業活動現金流量，此項結果與前者為加計流動性應計項目之資訊有關，而另外兩組無法得出結論。 二、營業而來的運用資金及現金流量增額資訊內涵之比較以年度資料觀之，民國80年的營業而來運用資金有超越盈餘及營業活動現金流量之增額資訊內涵。而從分組結果得知，高報酬組中，盈餘及營業而來的運用資金皆具有增額資訊內涵。 三、重大非營業項目及土地重估增值資訊內涵之比較以分組結果觀之，在高報酬組中，迴歸模式主要解釋能力來自盈餘，而處分投資、固定資產利得及土地重估增值均無增額資訊內涵；但在中、低報酬組及Pooling，處分固定資產利益皆具增額資訊內涵。 / This study aims to examine the incremental information contents of working capitals and cash flows which is mainly motivated by the mandated accounting regulation in relation to statement of cash flows on December 28, 1989. The empirical analysis includes 162 samples covering from 1991 to 1995. The findings can be summarized as follows. 1. In addition to the samples of 1991, no significant association between cash flows from operations (including working capitals from operations) and stock returns can be detected. Among high returns sample group, the working capital from operations significantly associates with stock returns, if all samples are pooled. 2. In 1991, the working capitals from operations has significant incremental information contents. In addition, among high returns samples the working capital from operations has significant incremental information contents, if all samples are pooled. 3. Among high returns samples, the explanatory power of stock returns is mainly derived from earnings. In addition, gain on disposal of fixed asset has significant incremental information contents in medium and low return sample groups.
