本文主要探討產物保險公司如何以自身的風險管理及內部的流程控制來達到有效的控管和預測，進而創造更高的業主權益報酬率，確保被保險人的權益，以維繫公司的永續經營發展為研究的目的。 身為風險管理工具之一的保險公司，必須瞭解自身於經營上面對的風險所在。首先論述如何建立保險公司風險管理程序，並從風險中深入分析，得知不適當的定價是造成保險公司喪失清償能力最主要的原因，建立完善的核保風險機制據以發展保險公司本身的核心價值，特以火險為例詳細說明其建制的過程與細節。 除介紹如何利用核保財務分析模型（Underwriting Financial Model）來解決適當訂價的問題，並配合運用風險資本額的公式求出各險種之風險資本額、各險種之業主權益分配額、各險種之可運用資金、各險種之自留綜合率、各險種業主權益報酬率、以預測來年之營運績效，另外尚討論信用風險與風險累積的控制，運用創新的觀念及技術來管理公司的業務量。 最後建議保險公司應設立風險管理專責單位，對於風險管理的流程與運作提早規劃準備，保險公司應有意願提昇風險管理的專業能力並嚴格自律及確實執行，俾強化公司自身風險觀念瞭解到公司真正有此需求。 關鍵字：風險管理、業主權益報酬、風險資本額、核保、產物保險經營 / The main theme of this research is to explore the issues related to the ways of risk management and internal operation control for insurance companies. The insurance companies could be efficiently controlled and projected to create higher return on equity, to guarantee the insured’s benefit, and to maintain the company’s long-term operation by implementing risk management process. Insurance companies, as one of the tools for risk management, are required to realize their own risks in operation. Firstly they must explore how to build up a process of risk management and to recognize that inadequate price is one of the main reasons to cause insurance company’s insolvency. Secondly they should explore how to build up an adequate underwriting risk mechanism to develop the core value of insurance companies, and to illustrate its process and detail of the building-up with Fire insurance business. Insurance companies are also required to know how to solve inadequate price by using Underwriting Financial Model, and how to calculate Risk Base Capital, Capital Allocation, Asset Allocation, Combined Ratio, Return on Equity for each line of business to predict business results for the coming year. This paper also discusses the importance of credit risk and risk accumulation in order that insurance companies can manage their own business by using innovating concept and technique. Finally Insurance companies are recommended to set up a risk management unit that should plan and prepare for the process of risk management. They ought to show their high wiliness to increase the capability of risk management, and to exercise high discipline and put into work in order to enhance the concept and need of risk management. Key Words： Risk Management, Return on Equity, Risk Base Capital, Underwriting, Insurance Operation.

本研究以2000年至2006年中國大陸上市公司之財務資料及股價資料，探討中國上市公司是否因租稅優惠而負擔隱含稅，及其負擔之隱含稅與有效稅率、股東權益稅前報酬率、市場結構及產業別之關係。實證結果顯示，中國大陸上市公司有效稅率之平均值遠低於其稅法上之名目稅率，顯示上市公司整體而言因稅法而享有租稅優惠，其中以農林漁牧業與信息技術業之有效稅率最低，反映中國扶植農業以及獎勵高科技產業之租稅政策。上市公司隱含稅率之平均值約為17.91%，顯示在中國大陸經濟成長率高之市場下，其上市公司仍須負擔隱含稅，且實證結果發現中國上市公司之有效稅率與隱含稅率呈顯著正向關係，即當有效稅率下降時，隱含稅率將會相對提高，呈現如Scholes and Wolfson(1992)所提出之隱含稅理論。 本研究實證結果亦發現，中國上市公司之股東權益稅前報酬率與隱含稅負間呈現顯著負向關係，即享受租稅優惠較多的公司，因負擔隱含稅成本，故整體報酬率未必高於享有較少租稅優惠的公司。非製造業公司之市場結構變數與隱含稅率間具有顯著關係性，即市場集中度越高時，廠商的市場支配力越大，也就越接近壟斷市場，造成該產業租稅優惠隱含稅負之負擔者多為消費者，而公司負擔之隱含稅則相對較低。 / This study uses financial and stock price data of the listed companies in China from 2000 to 2006, to examine if the listed companies have to bear implicit taxes because of tax preferential treatments, and to examine the relationship between implicit taxes and effective tax rates. The empirical results indicate that the average of ETRs of listed companies in China is lower than the statutory tax rate, indicating that overall listed Chinese companies have enjoyed substantial preferential tax treatments. The ETRs of the companies of agriculture and information technological industries are the lowest ones of all industries, reflecting China's tax policy aimed at developing agriculture and hi-tech industries. The average of implicit tax rates of listed companies in China is about 17.91%, indicating that listed companies in a high economics growth market, such as China, still have to bear implicit taxes. The empirical results show that implicit taxes are negatively related to ETRs, and the results support the implicit tax theory by Scholes and Wolfson(1992).The empirical results indicate the relationship between implicit tax and PEROEs is negatively, meaning the returns of tax-favored companies are less than tax-disfavored ones. The variables of market structures are significantly related to implicit tax, meaning the more market power the companies have, the less implicit tax they will bear. The empirical results of this study have implications for the government to further use tax incentives as a vehicle to stimulate economic development.

Abstract in English, Afrikaans and Zulu / This study is aimed at investigating the capital structures of the Johannesburg Stock Exchange listed South African IT firms and compare these to the capital structures of NASDAQ listed US IT firms in order to better understand the capital structures that JSE listed South African firms employ. The study made use of secondary data in the form of ratio analysis from public sources, as well as the published annual financial statements of the firms. The Generalised Method of Moments regression analysis technique was used in order to test the data for relationships between certain ratios. The study found positive relationships between the firm’s capital structure and its return on equity; meaning that firms should make use of their capital structures to maximise their return on equity and as a result, returns for its shareholders. / Hierdie studie is daarop gerig om die kapitaalstrukture van Suid-Afrikaanse IT-ondernemings wat op die Johannesburgse Aandelebeurs (JSE) genoteer is te ondersoek, en dit te vergelyk met die kapitaalstrukture van NASDAQ-genoteerde Amerikaanse IT-ondernemings ten einde die kapitaalstrukture wat JSE-genoteerde Suid-Afrikaanse ondernemings gebruik, beter te verstaan. Die studie het sekondêre data in die vorm van verhoudingsontleding uit openbare bronne, asook die gepubliseerde finansiële jaarstate van die ondernemings gebruik. Die Veralgemeende Metode van Momente-regressieanalisetegniek is gebruik ten einde die data vir verwantskappe tussen bepaalde verhoudings te toets. Die studie het positiewe verwantskappe tussen die ondernemings se kapitaalstruktuur en opbrengs op ekwiteit gevind; dit beteken dat ondernemings hul kapitaalstrukture behoort te gebruik om hul opbrengs op ekwiteit en gevolglik ook opbrengste vir hul aandeelhouers te maksimeer. / Lolu cwaningo kuhloswe ngalo ukuhlola izinhlaka ezifaka imali ezinkampanini zobuchwephese bamakhompuyutha ezisohlwini lwe-Johannesburg Stock Exchange (i-JSE), nokuziqhathanisa nezinhlaka ezifaka imali ezinkampanini zase-US zobuchwepheshe bekhompuyutha ezisohlwini lwe-NASDAQ ukuze kuqondakale kangcono izinhlaka ezifaka imali ezinkampanini zaseNingizimu Afrika ezisohlwini lwe-JSE.

The aim of this dissertation is to design finance management model and then to test it in real company operated in field of facility management (property and asset management in the field of real estate’s). Designed model works with instruments of financial analysis and investment management. Key hypothesis of the model tells that return on equity should by higher or equal in comparison to weighted average cost of capital. This hypothesis is used not only for effective financial management of the company but also for its smaller units (business centres). Part of the dissertation is definition how to implement and use the model (31 steps for the implementation). Designed model (and hypothesis as well) is verified on the case study.

It is acknowledged that the primary objective of any company should be the creation of shareholder-value. However, it is also recognised that there are other stakeholders, with their own financial and/or non-financial objectives, which could impact on a company's overall financial performance. Management should therefore identify stakeholder-groups which could impact on the company and formulate a model in addressing their objectives. This study integrates elements from the theory of shareholder-value, the agency-theory, the theory of property rights and different stakeholder orientation-models to develop the approach of responsible stakeholder-management in the creation of shareholder-value. Stakeholders can be grouped into economic, social and environmental components. The concept of sustainable development has exploded in recent years. Three main elements of sustainable development were identified, namely economic, social and environmental development, referred to as "Triple Bottom Line (TBL)". Several organisations have started focussing on the concept of sustainability by guiding the development of sustainability policies. However, the Global Reporting Initiative (GRI) has become the de facto global standard for reporting on sustainable development. The concept of TBL, and how the three elements of sustainability could contribute to the maximisation of shareholder-value, is discussed. The results of the empirical study, where the financial performance and shareholder-growth of companies listed on the JSE and which adopted and reported on the GRI-guidelines, were compared to a group of companies in the same index grouping of the JSE that had not formally adopted and reported on the guidelines, identified a clear trend that those reporting on their sustainability policies had had a much better growth in five of the six financial measures used than the comparative group. / Thesis (M.Com.

Bank capital has a critical role in banking business the world over. Capital is a principal aspect of regulation and will determine how long a bank remains in business from a regulatory point of view. Its cost and the regulatory amount have an impact on the competitiveness of an institution and will influence the rate of expansion of a bank. The contribution of capital to the profitability and survival of a commercial bank remain an unresolved empirical issue. Prior research on the relationship between capital and profitability has largely focused on developed economies, especially the USA, and Europe. However, the results have been inconclusive. There is no evidence of such kind of a research done to date that focuses on an emerging economy such as South Africa. The seemingly conflicting finding coupled with regulations imposing equity capital adequacy from the Basel 11 Accord present an opportune platform for further research on the relationship between capital and profitability. Using South Africa as a unit of analysis and using the Generalised Methods of Moments (GMM), and Panel Two Stage Least Squares (2SLS) or Pooled IV method as the estimation techniques, this study tested the hypothesis that there is a positive and statistically significant relationship between bank capital and profitability. The results from the study provide evidence of a positive relationship between capital ratio (CAR), return on equity (ROE) and return on assets (ROA) and supported the generally held notion that there is a positive relationship between bank capital and profitability. This research output provided new insights into the long-run impact of bank capital on profitability and survival. From a bank specific strategic decision-making perspective, this would assist financial institutions and investors in tailoring investment decisions in response to policy decisions that relate to bank capital. From the public policy perspective, this would assist both governments and regulators in formulating better- informed policy decisions regarding the importance of bank capital. / Business Management / D.

This study investigated the critical success factors that affect the effectiveness and efficiency of mergers and acquisitions, by soliciting responses from bank Chief Executives and case evidence from the South African banking industry for the period 1990 to 2015. The study applied a mixed-use methodology. The case study evidence was drawn from the formation of the “Big Four Banks” in South Africa, namely, Absa (“Barclays Africa Group”), First Rand Group, Nedbank Group and Standard Bank Group. The study found that when visions and values of merging banks were aligned, there was a greater chance of success. The study further found that culture compatibility of merging entities is paramount. Stakeholder acceptance was also found to have a strong impact on the chance of success or failure in mergers and acquisitions (M&A). The case evidence corroborated and substantiated that there was a positive Deal Value Added (DVA) trend before the merger activity and immediately thereafter, evidenced by positive share price appreciation resulting in increased market capitalisation. The quantitative results found that 56% of the sampled CEOs indicated that an 80% majority of bank mergers in the South African banking sector had created value over the long term, evidenced by 10-year return trends. This study contributes to the corpus of knowledge by generating an integrated assessment framework that can be applied even beyond the South African environment, by practitioners involved in mergers and acquisition activities. / Graduate SBL / D.B.L.

Primarily, we investigate the contribution of these three fundamentalist variables in explaining changes on stock returns. Comparatively, was also analyzed the explanatory power of traditional asset pricing models formed with proxies for risk factors: beta, size, B/M ratio, momentum and liquidity. Finally, we verified the consistency of the fundamental variables after combinations of these control variables. The population consisted of all non-financial companies with shares traded on the Bolsa de Valores de São Paulo - BOVESPA from January 1995 to December 2010. The forecast variables were estimated by a linear dynamic panel (ARELLANO, BOND, 1991) with a lag. To analyze the contribution of the variables in explaining the returns of the Brazilian market, we used panel data regressions between annual stock returns and the two groups of explanatory variables. Referring to the fundamentalist variables analyzed, we found that when they were used separately as a multifactor model, the future estimates of the B/M ratio and ROE were not statistically significant and had low explanatory power, suggesting that they have no relevance to the explanation of Brazilian stock returns. The expectations of B/M ratio and ROE were also combined with the current B/M ratio, forming an aggregate forecast variable. It was found that this variable was statistically significant and provided a considerable increase in the explanatory power of models that included it. Thus, Hypotheses 2 and 3 that the future expectations of B/M ratio and future expectations of ROE explain part of the variations on stock returns in Brazil cannot be rejected. The B/M ratio was tested as fundamentalist variable as proxy for risk factor, representing an overlapping variable between the two approaches. The results showed that the B/M ratio was positive and statistically significant in both the fundamental approach and the risk factors approach. Furthermore, when combined in the joint models, it contributed as a risk factor and as a component of the aggregate forecast variable. Thus, the Hypothesis 1 that B/M ratio explains part of changes in Brazilian stock returns cannot be rejected. With respect to the proxies of risk factors, we verified the existence of the B/M effect, a reversed momentum effect and a liquidity premium in the Brazilian capital market. In contrast, there was not found a size effect in the period analyzed. Moreover, the results obtained in this dissertation might contribute to the establishment of investment strategies in the stock market, since the B/M ratio plus the forecasts of the B/M ratio and ROE for the following year were able to explain some of the variations on stock returns for the same period. / Este trabalho teve como objetivo analisar a influência das expectativas futuras do índice book-to-market (B/M) e do Retorno sobre o Capital Próprio (ROE) como variáveis adicionais ao índice B/M atual, na explicação dos retornos do mercado de capitais brasileiro. Inicialmente, buscou-se investigar a contribuição dessas três variáveis fundamentalistas na explicação dos retornos das ações. Comparativamente, também foi analisado o poder explicativo de modelos de precificação tradicionais, formados por proxies para fatores de risco: beta, tamanho, índice B/M, momento e liquidez. Por fim, verificou-se a consistência das variáveis fundamentalistas, após combinações com essas variáveis de controle. A população foi composta por todas as empresas não-financeiras, com ações negociadas na Bolsa de Valores de São Paulo BM&FBOVESPA, no período de 1º de janeiro de 1995 a 31 de dezembro de 2010. As variáveis de previsão foram estimadas por meio de um painel linear dinâmico (ARELLANO; BOND, 1991), com uma defasagem. Para a análise da contribuição das variáveis na explicação dos retornos do mercado brasileiro, foram utilizadas regressões com dados em painel entre os retornos anuais das ações e os dois grupos de variáveis explicativas. Quanto às variáveis fundamentalistas analisadas, verificou-se que, quando utilizadas separadamente, na forma de modelo multifatorial, as estimativas futuras do índice B/M e do ROE foram estatisticamente não significativas e apresentaram baixo poder explicativo, não se mostrando relevantes para a explicação dos retornos das ações brasileiras. As expectativas do B/M e do ROE também foram combinadas com o índice B/M observado, formando uma variável de previsão agregada. Constatou-se que essa variável foi estatisticamente significativa e proporcionou um aumento considerável na capacidade explicativa dos modelos que a incluíram. Diante disso, as hipóteses 2 e 3 da dissertação, de que a expectativa futura do índice B/M e a expectativa futura do ROE explicam parte das variações dos retornos das ações brasileiras, não podem ser rejeitadas. O índice B/M foi testado como variável fundamentalista e como proxy para fator de risco, constituindo uma variável de sobreposição entre as duas abordagens. Os resultados evidenciaram que o índice B/M foi positivo e estatisticamente significativo, tanto nos modelos da abordagem fundamentalista, como nos modelos de fatores de risco. Além disso, quando inserido nos modelos conjuntos, verificou-se a sua contribuição como fator de risco, bem como componente da variável de previsão agregada. Dessa forma, a hipótese 1, de que o índice B/M explica parte das variações dos retornos das ações brasileiras, não pode ser rejeitada. Com relação às proxies de fatores de risco, verificou-se a existência do efeito B/M, de um efeito momento invertido e de um prêmio de liquidez no mercado de capitais brasileiro. Em contrapartida, não se observou a existência de um efeito tamanho, no período analisado. Ademais, ressalta-se que os resultados obtidos nesta dissertação podem contribuir para estabelecimento de estratégias de investimento no mercado de ações, uma vez que a combinação entre o índice B/M atual e as previsões do índice B/M e do ROE, para o ano seguinte, foram capazes de explicar parte das variações dos retornos das ações no mesmo período.
