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.

A amostra foi formada por 159 companhias, sendo 57 pertencentes e 102 não pertencentes à carteira ISE. O período de análise compreende os anos de 2005 a 2014, correspondendo o ano de 2005 à criação do ISE. A análise dos dados foi efetuada mediante a utilização da análise envoltória de dados (DEA - data envelopment analysis) pelo método BCC, definido por Banker, Charnes e Cooper (1984), também conhecido como retorno variável de escala (VRS - variable returns to scale) com orientação ao produto, ou seja, a maximização dos outputs. As variáveis utilizadas na análise como inputs foram o ativo circulante, ativo imobilizado e o custo dos produtos vendidos e como output o lucro operacional. Toda a análise foi desenvolvida observando os segmentos de cada grupo de empresa da amostra de forma isolada, visando evitar distorção nos dados. Os resultados obtidos revelam que as companhias da carteira ISE apresentam eficiência operacional inferior às demais companhias, à medida que não alcançaram eficiência operacional de 100% (DEA – BCC – VRS) ao longo dos anos, o que leva a se concluir que o fato dessas companhias serem consideradas como de conduta sustentável, isso necessariamente não se reflete em sua eficiência operacional. / The research aimed to analyze the operational efficiency of companies belonging and not belonging to the theoretical portfolio of the Corporate Sustainability Index (ISE) of BM&FBOVESPA through data envelopment analysis. The sample was comprised of 159 companies, of which 57 owned and 102 non-ISE. The analysis period covers the years 2005 to 2014, corresponding to 2005 to the ISE creation. Data analysis was performed by using the data envelopment analysis (DEA) by the BCC method defined by Banker, Charnes and Cooper (1984), also known as variable returns to scale (VRS) with the product orientation, that is, the maximization of output. The variables used in the analysis were as inputs current assets, fixed assets and the cost of sales and operating profit as output. All analysis was developed observing the segments of each company in the sample group in isolation, in order to avoid distortion in the data. The results show that the ISE portfolio companies have lower operating efficiency to other companies, as they have not achieved operating efficiency of 100% (DEA - BCC - VRS) over the years, which leads to the conclusion that the fact that these companies are considered sustainable conduct, not necessarily reflected in operational efficiency.

台灣因本身自然資源並不豐富，屬於典型的開放性海島經濟，對國際貿易依存度高。匯率是重要的影響台灣總體經濟因素。因亞洲金融風暴影響，導致台幣兌美元匯率大幅貶值。本篇論文旨在探討，自民國86年7月始，新台幣大幅貶值，此項匯率的巨幅波動（波動期）與83年7月至86年6月間（平穩期），究竟對上市公司的營業績效及上市公司的股票報酬，是否造成不同之影響。利用營業利潤受匯率變動的影響，來解釋公司的外匯風險，進一步探討匯率變動與上市公司股票異常報酬的關係。 探討匯率變動對公司營業利潤的影響，可藉由契約，外匯換算或競爭效果表現出來。所謂契約效果是公司在國際貿易的環境下，有不可取消的外匯合約，造成營業利潤該增加而未增加，或應減少而未減少，立即反映出來對公司營業利潤的影響。外匯換算效果是指公司擁有國外子公司，當國外子公司匯寄外幣現金回母公司時，因受匯率變動而產生的風險，會在財務報表上反映出來．競爭效果是指因進出口貿易頻繁，匯率變動會影響公司的競爭情勢，通常不會立即直接的反映出來，而是間接的影響公司的銷貨收入和進貨成本，而延後反映在財務報表上。本研究試圖檢視匯率變動對公司利潤的影響是立即反映，還是延後反映，以瞭解哪一個效果較顯著。 此外，本研究也檢視匯率變動對公司股票異常報酬變動的影響是立即或延後反映，以瞭解投資者對於匯率變動對股價變動影響認知的反應程度。當企業受匯率變動而產生會計或經濟風險時，任何對公司價值之影響，在效率市場的情形下，應當會立即反映在股票價格上。 本研究實証結果發現，匯率平穩期，契約及競爭效果顯著。但在匯率波動期，契約及競爭效果不顯著。台灣股市，不論在匯率平穩期或波動期，匯率波動皆對公司當季股票異常報酬有顯著影響力，顯示台灣股市投資人十分重視匯率走向。平穩期或波動期，匯率變動會遞延影響公司股票異常報酬，間接驗証台灣股市非為效率市場。同時，以出口為導向的產業，匯率變動對該產業的股票異常報酬有顯著的影響。 關鍵詞：匯率變動、營業利潤、股票異常報酬 / The purpose of this paper is to identify the categories of exposure that are most likely to effect company's operating income and the observed association between exchange rate changes and abcdrmal stock returns. The period examined in this paper is July 1994 to December 1997. This period examined is divided .One is July 1994 to June 1997(Exchange rate changes wave is flat) and the other is July 1997 to December 1997(Exchange rate changes wave is inflectional). This paper attempts to understand the different associations among operating income exchange rate changes and abcdrmal stock returns between July 1994 to June 1997 and July 1997 to December 1997. This paper finds that contractual effects and competitive effects are most likely to explain impact of exchange rate changes and unexpected operating income in July 1994 to June 1997. The association between exchange rate changes and abcdrmal stock returns is at relatively high significance levels between July 1994 to June 1997 and July 1997 to December 1997. The Taiwan Stock market investors have more attention on exchange rate changes waves. The a-quarter lagged relation between exchange rate changes and abcdrmal stock returns are at relatively high significance levels in July 1994 to June 1997. The a-quarter and two-quarter lagged relation between exchange rate changes and abcdrmal stock return are at relatively high significance levels in July 1997 to December 1997. This result examines Taiwan stock market is inefficiency Keywords: operating income, exchange rate changes, abnormal stock returns

Neste sentido, o presente trabalho trata do tema da melhoria da utilização de bens de capital dos hospitais, através da adoção do conceito de Índice de Rendimento Operacional Global (IROG). Objetiva, ainda, a proposição de um modelo de gestão econômica para a avaliação da eficiência dos equipamentos de alta tecnologia em hospitais que possibilite a maximização da utilização da capacidade instalada, no intuito de aumentar o Ganho da empresa, com os mesmos ativos fixos. Estruturou-se, portanto, através de um Estudo de Caso múltiplo, aplicado no Hospital Moinhos de Vento. Realizaram-se, para tanto, a análise e a medição do IROG de dois equipamentos, a fim de verificar a possibilidade de aumentar a produtividade, a capacidade de atendimento mais rápido da demanda e identificar as principais paradas e falhas ocorridas durante a realização de exames em duas áreas distintas do hospital, a saber: Unidades de Angiografia e Diagnóstico de Imagem. Os elementos utilizados para o desenvolvimento do método foram: a) consulta ao referencial teórico sobre o tema; b) definição e aplicação do método em duas áreas distintas de empresa; c) contribuições de gestores e de colaboradores das áreas; d) contribuições oriundas do próprio autor do trabalho. Os principais resultados obtidos através da aplicação do método foram: i) obtenção da medição e constatação do baixo índice do IROG em dois equipamentos de capital; ii) maior clareza e discernimento dos gestores das áreas em relação à eficiência da utilização dos equipamentos; iii) identificação dos principais motivos de paradas dos equipamentos; v) simulação de cenários de melhoria na eficiência dos equipamentos e apresentação de Ganhos financeiros; vi) introdução da medição do IROG na relação dos indicadores do hospital. Por fim, o tema estudado poderá evoluir, principalmente, em organizações focadas na melhoria dos seus processos operacionais e em planos de ação para estabelecer um processo sistemático de melhoria contínua da sua gestão. / This work aims to contribute for the development and improvement of the management of hospital organizations. In this sense, the present work deals with the issue of improving the utilization of capital assets of hospitals, by adopting the concept of Index Global Operating Income ( IROG ). It also aims to propose a model of economic management to assess the efficiency of high-tech equipment in hospitals which enables the maximization of capacity utilization in order to increase the gain of the company, with the same fixed assets. Thus, the work was structured through a multiple case study, applied in the Moinhos de Vento Hospital. There were, therefore, the analysis and measurement of the IROG of two devices in order to verify the possibility of increasing the productivit, the ability to quickly meet demand and identify key stops and failures during examinations in two distinct areas of the hospital namely: Angiography and Image Diagnostic Units. The elements used for the method development were: a) consulting the theoretical framework on the topic; b ) definition and application of the method in two distinct areas of business; c ) contributions of managers and employees from areas; d) Contributions from the author of the work. The main results obtained by applying the method were : i ) obtaining the measurement and verification of low IROG index in two capital equipment;, ii ) greater clarity and insight of managers of areas in relation to efficiency of use of equipment; iii ) identification of the main reasons for equipment downtime; v) simulation scenarios for improving the efficiency of equipment and presentation of financial gains; vi ) introduction of measurement indicators IROG in respect of the hospital. Finally, the subject studied may evolve, especially in organizations focused on improving its operational processes and action plans to establish a systematic process for continuous improvement of their management.

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.

在會計理論上，關於損益的計算，有兩種重要所得觀念：當期營業所得觀念與全含所得觀念。早期會計界採當期營業所得觀念（營業淨利），目前公報規定的淨利則採折衷辦法，但較偏向全含所得觀念，最近有許多學者提倡全含所得觀念（綜合淨利）。究竟何種所得觀念對投資人最為有用，實有加以探討的必要，此乃本文的目的。 　　本研究採用“關聯性研究設計”(Association Study)來探討營業淨利、淨利及綜合淨利與股票報酬的關係，以瞭解何種盈餘定義對投資人最為有用，並進一步檢視淨利相對於營業淨利、綜合淨利相對於淨利是否具有增額資訊內涵。 　　本研究以55家公開上市公司民國72年至民國81年的財務資料進行實證研究，實證結果如下： 　　1、營業淨利、淨利及綜合淨利均具有資訊內涵。 　　2、在相對資訊內涵比較方面，經由t檢定顯示，營業淨利、淨利及綜合淨利在解釋股票報酬能力上，並無顯著差異存在。 　　3、在增額資訊內涵比較方面，經由t檢定顯示，營業淨利外但包含於淨利中的損益項目，具有增額資訊內涵。 　　4、在增額資訊內涵比較方面，經由t檢定顯示，淨利外但包含於綜合淨利中的損益項目，亦具有增額資訊內涵。 　　5、報酬累計期間起迄時點不同，對同一年度同一盈餘與股票報酬的相關程度，具有重大的影響。
