An evaluation and comparison of Value at Risk and Expected Shortfall

Given the rapid and sustained growth of Aspen over the past decade, the main aim of this study is to identify and analyze the growth strategies, adopted by Aspen over the period from 2004 to 2014. The research method used was a descriptive study through a single case study of Aspen by analyzing secondary data in the form of publicly available company reports and presentations, as well as financial results, issued between 2004 and 2014. The study finds that, guided by strategic and visionary leadership, Aspen adopted a number of growth strategies including (i) organic growth, as a key factor in creating incremental value for Aspen and its stakeholders, (ii) inorganic growth, in the form of carefully planned and well executed acquisitions, aligned to the Group strategy, (iii) extending territorial coverage through global expansion, particularly into emerging pharmaceutical countries, and (iv) ongoing investment in production capabilities as a means of achieving a strategic advantage. Despite the challenges of intense competition, restrictive legislation, pressure on medicine prices, currency volatility and market specific risks, Aspen has delivered double-digit earnings growth to its shareholders for 16 consecutive years.

In order to ensure profitability for shareholders, optimal contracting recommends the alignment between executive compensation and company performance. Large organizations have therefore adopted executives remuneration systems in order to induce positive market reaction and motivate executives. Complex compensation schemes are designed by Boards of Directors using strong pay-performance incentives that explain high levels of executive pay along with company size, demand for management skills and executive influence. However, the literature remains inconclusive on the pay-performance relationship owing to the various empirical methods used by researchers. Additionally, there has been little effort in the literature to compare methodologies on the pay-performance relationship.
Using the dominant agency theory framework, the purpose of this study is to establish and examine the relationship between firm performance and executive pay. In addition, it intends to assess the characteristic of model specifications commonly adopted. To this aim, a quantitative analysis consisting of three complementary methods was performed on panel data from South African listed companies. The results of the main unrestricted first difference model indicate a strong non-linear relationship where the impact of current and previous firm performance on executive pay can be observed over 2 to 4-year period providing support to the optimal contracting theoretical perspective in the South African business context. In addition, CEO pay is more sensitive to firm performance as compared to Director pay. Lastly, although it affects executive pay levels, company size is not found to improve the pay-performance relationship.

Despite the benefits that mobile banking has to offer, coupled with positive mobile penetration rates, the use of mobile devices to perform banking transactions and access financial information is not as widespread as expected. The significantly sized Generation Y cohort is a rewarding market segment for retail banks. In South Africa, however, this cohort’s mobile banking adoption is largely under-researched. Understanding the antecedents that positively influence Generation Y students’ attitudes towards and usage behavior of mobile banking will assist retail banks in their efforts to tailor their business and marketing strategies effectively towards this cohort, and in doing so, foster increased acceptance of their mobile channels. As such, the purpose of this study was to extend the technology acceptance model (TAM) and determine the influence of perceived ease of use, relative advantage, subjective norms, perceived behavioral control, perceived integrity and the perceived system quality of mobile banking on South African Generation Y students’ attitudes towards and usage behavior of mobile banking. Following a descriptive research design, self-administered questionnaires were completed by a non-probability convenience sample of 334 students registered at the campuses of three registered public South African universities located in the Gauteng province. Data analysis included correlation analysis and structural equation modeling. The findings suggest that while perceived ease of use, perceived integrity and the perceived system quality predict Generation Y students’ mobile banking usage behavior, subjective norms, perceived behavioral control and the perceived relative advantage of mobile banking predict attitudes towards mobile banking, which, in turn, predict their mobile banking usage behavior.
