It is in the area of the regulation of a company's share capital and distributions to shareholders that the inherent conflict between creditors and shareholders, and the fragile balance among shareholders internally, intersect. The share capital of a company underlies its corporate structure and represents not only its initial own funds from which creditors can be paid, but also the relative equity interests of the shareholders. The balance between shareholders can be disturbed by capital reorganisations through increase, reduction or variation of share capital or through disproportionate contributions by, or distributions to, shareholders. Share repurchases are particularly risky in this regard. Creditor interests are affected when their prior right to payment is endangered by distributions to shareholders. This study analyses the South African Law relating to share capital and distributions against the background of a comparative study of the laws of England, New Zealand, Delaware and California, as well as the provisions of the American Model Business Corporations Act. Two main approaches to creditor protection are evident. The capital maintenance doctrine, which is followed in England and Delaware, protects creditors by emphasising the notional share capital of the company as a limit on distributions. In contrast, the solvency and liquidity approach focuses on the net assets of the company and on its ability to pay its debts. New Zealand, California and the Model Business Corporations Act represent this approach. Regulatory responses to shareholder protection range from insistence on compliance with procedural requirements to minimal statutory intervention in the internal affairs of companies, instead relying on general principles of fairness and good faith. There is little correlation between a particular system's approach to creditor protection on the one hand, and to shareholder protection on the other. England, New Zealand and South Africa prescribe specific formalities, while the American approach is more relaxed. South Africa is a hybrid system. Its transition from capital maintenance to solvency and liquidity has been incomplete and its protection of equity interests is relatively unsophisticated. A number of recommendations are made for an effective and coherent approach that will safeguard the interests of creditors and shareholders alike. / School: Law / LL.D.

The Companies Act of 71 of 2008 makes a number of important changes to the rules relating to capital maintenance. In line with the objectives of the Companies Act of 71 of 2008, section 44 of the Act has removed the prohibition on the provision of financial assistance by a company which was contained under the previous section 38 of the Companies Act 61 of 1973. Despite the repeal of the prohibition, a transaction which involves the provision of financial assistance by a company for the acquisition of or subscription of its own securities still needs to be effected in accordance with the requirements and conditions that are provided under the Act and Memorandum of Incorporation. To explore the new developments, within this study, the provision of financial assistance in terms of section 44 of the Companies Act of 2008 is, therefore, analysed in detail. On the other hand, the UK Companies Act of 2006 repealed the prohibition on the giving of financial assistance by private companies in most circumstances. It, however, retained the prohibition to public companies only because of the requirements of the Second Company Law Directive (77/91/EEC). This study also explores the rules of financial assistance by a company under the UK Companies Acts in detail. Though the source of financial assistance by a company both in South Africa and in English Company laws is rooted in the English decision of the Trevor v Whitworth case, currently these countries have adopted what is deemed appropriate and significant in their own countries. This study, therefore, examines and compares the rules governing the provision of financial assistance by a company in the company laws of these two countries. / Mercantile Law / LL.M.

[pt] Uma importante questão que se coloca para entidades abertas de previdência complementar e sociedades seguradoras que operam previdência complementar é a definição de uma gestão dos ativos e passivos (do inglês ALM – Asset and Liability Management). Tal questão se torna mais relevante em um cenário de alta competitividade, margens operacionais decrescentes, garantias mínimas de rentabilidade para um passivo estocástico de longo prazo e um período de queda da rentabilidade dos instrumentos financeiros, sendo estes muitas vezes de difícil precificação e pouco previsíveis num mercado volátil como o brasileiro. Somada a estas dificuldades, as companhias deste mercado estão sujeitas a uma regulação baseada em riscos, oriunda de práticas internacionais, adotada pelo órgão superior, Susep, que impõe restrições regulamentares para a manutenção da solvência das companhias, o que eleva a dificuldade da definição de um modelo. Diante deste cenário, esta dissertação apresenta uma proposta de ALM baseada em um modelo de programação estocástica multiestágio que tem como objetivo definir dinamicamente a alocação ótima dos ativos, incluindo títulos com pagamentos de cupons, e mensurar o risco de insolvência da companhia para o horizonte de planejamento. / [en] An important issue of open pension funds and insurance companies that operate supplementary pension is the definition of an asset and liability management (ALM) framework. Such a question becomes more relevant in a scenario of high competition, declining operating margins, minimum guaranteed returns to a stochastic long-term liability and a period of falling returns on financial instruments, these being often difficult to pricing and predictable in a volatile market such as Brazil. Added to these issues, those companies are subject to a risk-based regulation, derived from international practices adopted by the national insurance regulator, Susep, which imposes constraints to maintain solvency of companies and therefore increases the complexity of an ALM framework. Due this condition, this dissertation presents a proposition of ALM based on a multistage stochastic programming model, which aims to define a dynamic optimal asset allocation, including bonds with coupons payment, and measure the company s insolvency risk for the planning horizon.

[pt] Com as falências ocorridas nas últimas décadas, no setor de seguros, um movimento surgiu para desenvolver modelos matemáticos capazes de ajudar no gerenciamento do risco, os chamados modelos internos. No Brasil, a SUSEP, seguindo a tendência mundial, exigiu que as empresas, interessadas em atuar no país, utilizassem um modelo interno para risco de subscrição. Com isto, obter um modelo interno tornou-se primordial para as empresas seguradoras no país. O modelo proposto neste trabalho ilustrado para seguro de vida para risco de subscrição se baseia em Cadeias de Markov, no Teorema Central do Limite, parte paramétrica, e na Simulação de Monte Carlo, parte não paramétrica. Em sua estrutura foi considerada a dependência entre titular e dependentes. Uma aplicação a dados reais mascarados foi feita para analisar o modelo. O capital mínimo requerido calculado utilizando o método híbrido foi comparado com o valor obtido utilizando somente o método paramétrico. Em seguida foi feita a análise de sensibilidade do modelo. / [en] The bankruptcies occurred in recent decades in the insurance sector, a movement arose to develop mathematical models capable of assisting in the management of risk, called internal models. In Brazil, the SUSEP, following the worldwide trend, demanded that the companies, interested in working in the country, using an internal model for underwriting risk. Because of this, developing an internal model has become vital for insurance companies in the country. The proposed model in this work illustrated to life insurance for the underwriting risk was based on the Markov chains, on the Central Limit Theorem to the parametric method, and Monte Carlo Simulation to the non-parametric method. In its structure, the dependence between the holder and dependents was considered. An application to masked real data was made to analyze the model. The minimum required capital calculated using the hybrid method was compared with the value obtained using only the parametric method. Then the sensitivities of the model were investigated.

Cette thèse a pour objet d'étude les méthodes numériques d'approximation de la densité de probabilité associée à des variables aléatoires admettant des distributions composées. Ces variables aléatoires sont couramment utilisées en actuariat pour modéliser le risque supporté par un portefeuille de contrats. En théorie de la ruine, la probabilité de ruine ultime dans le modèle de Poisson composé est égale à la fonction de survie d'une distribution géométrique composée. La méthode numérique proposée consiste en une projection orthogonale de la densité sur une base de polynômes orthogonaux. Ces polynômes sont orthogonaux par rapport à une mesure de probabilité de référence appartenant aux Familles Exponentielles Naturelles Quadratiques. La méthode d'approximation polynomiale est comparée à d'autres méthodes d'approximation de la densité basées sur les moments et la transformée de Laplace de la distribution. L'extension de la méthode en dimension supérieure à $1$ est présentée, ainsi que l'obtention d'un estimateur de la densité à partir de la formule d'approximation. Cette thèse comprend aussi la description d'une méthode d'agrégation adaptée aux portefeuilles de contrats d'assurance vie de type épargne individuelle. La procédure d'agrégation conduit à la construction de model points pour permettre l'évaluation des provisions best estimate dans des temps raisonnables et conformément à la directive européenne Solvabilité II. / This PhD thesis studies numerical methods to approximate the probability density function of random variables governed by compound distributions. These random variables are useful in actuarial science to model the risk of a portfolio of contracts. In ruin theory, the probability of ultimate ruin within the compound Poisson ruin model is the survival function of a geometric compound distribution. The proposed method consists in a projection of the probability density function onto an orthogonal polynomial system. These polynomials are orthogonal with respect to a probability measure that belongs to Natural Exponential Families with Quadratic Variance Function. The polynomiam approximation is compared to other numerical methods that recover the probability density function from the knowledge of the moments or the Laplace transform of the distribution. The polynomial method is then extended in a multidimensional setting, along with the probability density estimator derived from the approximation formula. An aggregation procedure adapted to life insurance portfolios is also described. The method aims at building a portfolio of model points in order to compute the best estimate liabilities in a timely manner and in a way that is compliant with the European directive Solvency II.
