In this thesis we provide insights into the behavior of financial managers of utility companies by studying their decisions to redeem callable preferred shares. In particular, we investigate whether or not an option pricing based model of the call decision, with managers who maximize shareholder value, does a better job of explaining callable preferred share prices and call decisions than do other models of the decision. In order to perform these tests, we extend an empirical technique introduced by Rust (1987) to include the use of information from preferred share prices in addition to the call decisions. The model we develop to value the option embedded in a callable preferred share differs from standard models in two ways. First, as suggested in Kraus (1983), we explicitly account for transaction costs associated with a redemption. Second, we account for state variables that are observed by the decision makers but not by the preferred shareholders. We interpret these unobservable state variables as the benefits and costs associated with a change in capital structure that can accompany a call decision. When we add this variable, our empirical model changes from one which predicts exactly when a share should be called to one which predicts the probability of a call as the function of the observable state. These two modifications of the standard model result in predictions of calls, and therefore of callable preferred share prices, that are consistent with several previously unexplained features of the data; we show that the predictive power of the model is improved in a statistical sense by adding these features to the model. The pricing and call probability functions from our model do a good job of describing call decisions and preferred share prices for several utilities. Using data from shares of the Pacific Gas and Electric Co. (PGE) we obtain reasonable estimates for the transaction costs associated with a call. Using a formal empirical test, we are able to conclude that the managers of the Pacific Gas and Electric Company clearly take into account the value of the option to delay the call when making their call decisions. Overall, the model seems to be robust to tests of its specification and does a better job of describing the data than do simpler models of the decision making process. Limitations in the data do not allow us to perform the same tests in a larger cross-section of utility companies. However, we are able to estimate transaction cost parameters for many firms and these do not seem to vary significantly from those of PGE. This evidence does not cause us to reject our hypothesis that managerial behavior is consistent with a model in which managers maximize shareholder value.

The liability of companies for extra-territorial human rights violations does not solely arise from human rights statutes and traditional tort law approaches, but also from the corporate and securities law domains. Securities law requires that public companies disclose any high risk activity that the company is involved in, to the extent that it may affect the viability of the corporation, and this includes possible human rights violations. Management decisions in the field of Corporate Social Responsibility must concern the long-term viability of a company, and therefore accommodating, to the extent possible, the demands of stakeholders – be they traditional shareholders, responsible shareholders, or affected communities. This thesis will analyze the legal obligations triggering such corporate decisions, as well as the industry trends which inform them. The focus will be on Canadian public mining companies.

This study sought to investigate the effectiveness of initial public offerings (IPOs) on the Zimbabwe Stock Exchange (ZSE), as an investment option in comparison to their seasoned matching firms and to establish why an investor would prefer buying into an IPO and not into already trading matching firms. The study also sought to determine the extent of IPO underpricing and to establish if there is a relationship between underpricing and the long-run performance of IPOs. This study further sought to establish the reasons behind the investors' over-optimism in IPOs despite their uncertainty as well as to establish the factors governing the success or failure of IPOs. A matching firm was judgementally selected for each of the IPOs listed on the ZSE during the period 1997 to 2002, for the purposes of comparing the short and long-run buy and hold returns. Returns for the 15 qualifying IPOs and 15 seasoned matching firms were analysed and the share price performance compared in event windows of 30 days, 1 year, 2 years, 3 years, 4 years and 5 years from the respective IPO dates. Questionnaires were also administered on a sample of 50 major stock market investors comprising stockbrokers, mutual funds, insurance companies, pension funds and merchant banks to test various theoretical propositions on these IPOs. Consistent with Majaya (2002) and Mutsigwa (2004), this study finds that there is substantial underpricing of IPOs in Zimbabwe with an average of 28% underpricing. This paper also finds that IPOs in Zimbabwe leave money on the table as a result of underpricing. The study finds that IPOs offer higher short-run returns than their seasoned matching firms and consistent with Brav and Gompers (1997), that there is no difference between the long-run performance of IPOs and that of their seasoned matching firms. This study finds no evidence of a relationship between underpricing and long-run IPO performance. The study also finds that the market condition, the timing of placement of an IPO and the firm size and age are some of the key factors determining the success or failure of an IPO and that oversubscription of IPOs on the ZSE is attributed to the size of the bourse which is too small, to cope with the demand for IPO shares. This study concludes that IPOs are risky investment and recommends that investors should carry out detailed analysis on the future prospects of an IPO before buying shares. Ascertaining the true value of a share may help the investor decide whether or not to invest in an IPO. The study recommends that the ZSE management should explore the possibility of setting up an exchange for small capitalisation stocks and that they should remove some of the restrictive listing requirements to enable more companies to list and access capital for expansion and other projects in a country already starved of foreign direct investment due to economic sanctions. / Thesis (MBA)-University of KwaZulu-Natal, 2006.
