Thesis (MBA (Business Management))--University of Stellenbosch, 2008. / ENGLISH SUMMARY: During the period of change in South Africa in the year of the first democratic elections, 1994, the first King Report on Corporate Governance appeared. For the first time in South Africa, companies had a good reference for corporate practice and conduct. A second King report, commonly referred to as King II, appeared in March 2002 and expanded on the earlier Code to produce, what was considered at the time to be, a world-class code of corporate governance. In addition to the acceptance and incorporation of King II into corporate governance practice, the JSE included compliance with the King Code as part of its listing requirements. The code itself is not an enforceable set of rules, but rather guidelines to assist companies in implementing principles of good governance. In similar vein, the JSE has given companies the flexibility to justify non-compliance. This underscores the socalled comply or explain philosophy to which corporate governance in South Africa subscribes. Studies have found the level of corporate governance in South Africa to be high, especially for an emerging market. Compliance with corporate governance principles and transparency go hand in hand. In a comply or explain regime, where the regulation is considered to be done by the market, disclosure of compliance is especially important. The goal of this research project was to conduct a survey of the top listed South African companies to ascertain what the level of disclosure of corporate governance was, with specific reference to the recommendations contained in the King Code. For the purposes of this study, the top companies were defined as the FTSE/JSE Top 40 Index companies. The supposition was that most companies, having been confronted with the King Code for almost six years, would be compliant to a large degree and will disclose their compliance. This was expected to be more evident amongst top companies who have the resources and influence to effect changes sooner and take the lead on high profile issues. The study confirmed the supposition that companies, at least in the sample, were highly compliant. There were however some areas where improvements can be made to be more in line with global best practices. / AFRIKAANSE OPSOMMING: Gedurende die periode van vernuwing in Suid-Afrika en die jaar van die eerste demokratiese verkiesing, 1994, het die eerste King verslag op korporatiewe bestuur verskyn. Vir die eerste keer het maatskappye in Suid-Afrika ‘n goeie verwysing gehad in die bepaling van hul korporatiewe bestuurspraktyke en gedrag. ‘n Tweede King verslag, alombekend as King II, het in Maart 2002 verskyn en op die eerste verslag uitgebou om ‘n kode te voorskyn te bring wat ten tyde van publisering as wêreldklas bestempel is. Bo en behalwe die aanvaarding en toepassing van King II in die korporatiewe bestuurspraktyk, het die JSE ook nakoming van die Kode as deel van die noterings vereistes ingesluit. Die King Kode opsigself is nie ‘n afdwingbare stel reëls nie, maar eerder riglyne wat maatskappy bystaan in die implementering van beginsels van goeie bestuur. In ‘n soortgelyke manier gee die JSE ook aan maatskappye die buigsaamheid om gevalle van nie-nakoming te regverdig en verdedig. Dit onderskryf die sogenaamde voldoen of verduidelik filosofie wat korporatiewe bestuur in Suid Afrika aan gehoor gee. Studies het gevind dat die vlak van korporatiewe bestuursgedrag in Suid-Afrika hoog is, veral vir ‘n ontluikende mark. Nakoming met korporatiewe bestuurgedragskodes en deursigtigheid gaan hand aan hand. In ‘n voldoen of verduidelik regime, waar die mark geag word om te reguleer, is openbaarmaking van korporatiewe bestuursgedrag van kardinale belang. Die doel van hierdie navorsingsprojek was om ‘n peiling te maak van die voorste Suid-Afrikaanse maatskappye om te bepaal wat die vlak van openbaarmaking in terme van korporatiewe bestuursgedrag was, met spesifieke verwysing na die King Kode. Vir die doeleindes van die studie is die voorste maatskappye gedefiniëer as die FTSE/JSE Top 40 Indeks. Die veronderstelling was dat meeste maatskappye, gegewe die feit dat die Kode al ses jaar in omgang is, tot ‘n groot mate aan die Kode sal voldoen en inligting rakende die voldoening openbaar maak. Dit is ook verwag dat dit veral die geval onder die voorste maatskappye sou wees aangesien hulle oor die hulpbronne en invloed beskik om veranderinge vroeër teweeg te bring en leierskap te neem met hoë profiel kwesssies. Die studie het die veronderstelling korrek bewys dat maatskappye, ten minste in die geval van die ingeslote groep, ‘n hoë vlak van voldoening en openbaarmaking ten toon stel. Daar is egter nogtans areas waar verbeterings gedoen kan word om meer in lyn met internasionale beste praktyke te kom.

Thesis (MComm)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The management of human capital requires meaningful measures of human capital effectiveness that enable better strategic human resource decision-making. Existing measures, such as Human Capital Return on Investment (HCROI), allow human resource managers to quantify the bottom-line impact of human capital expenditure, but little is known about how HCROI varies within the population of listed companies. As a result, users of these metrics rarely know how they ‘measure up’ against their competitors in the absence of normative information. If human capital is considered a source of competitive advantage, measures of human capital effectiveness should also allow for normative comparisons. The present study extracted audited financial data from McGregor BFA (2010) and described the central tendency and dispersion of HCROI of Johannesburg Stock Exchange (JSE) listed companies (N = 319). In doing so, it established a set of benchmarks for human capital effectiveness measures across industry and company size categories, as well as described temporal changes over the financial years surveyed (2006 - 2010). Even though South Africa is considered to have a very low labour force productivity level compared to other countries (Schwab, 2010 in World Competitive Report, 2010/2011), the results showed that the grand median HCROI ratio for South African listed companies was higher (M = 3.03) than those from published figures from the USA, EU and UK (PwC Saratoga, 2011). This descriptive research also explored the influence of company size (small, medium or large) and company industry (N = 42) on human capital effectiveness (as indexed by HCROI). No statistically significant differences (p > .05) between the median HCROI ratios across company size categories were found, although notable differences in medians of HCROI across company industry categories were observed. HCROI also showed temporal fluctuations over the study period, reflecting economic cycle influences, but year-on-year changes were bigger when the mean HCROI was used — median HCROI remained relatively stable year-on-year. From the research, several recommendations are made regarding the appropriate use of these HCROI benchmark data. Also, this descriptive study lays a solid foundation for future explanatory research aimed at investigating the antecedents, correlates and consequences of human capital return-on-investment (HCROI) as an indicator of human capital effectiveness. The present study contributes to human capital metrics literature by demonstrating how human capital effectiveness indicators can be calculated from audited financial results available in the public domain, and in doing so, attempts to encourage greater use of human capital reporting in financial reporting standards. / AFRIKAANSE OPSOMMING: Die bestuur van mensekapitaal vereis betekenisvolle metings van menskapitaaleffektiwiteit wat beter strategiese menslike hulpbron-besluitneming tot gevolg het. Bestaande metings, soos Menskapitaalbeleggingsopbrengs (HCROI), laat menslike hulpbronbestuurders toe om die finansiële impak van die menskapitaaluitgawe te kwantifiseer, maar min is bekend oor hoe menskapitaalbeleggingsopbrengste tussen die populasie van gelyste maatskappye varieer. Die gevolg is dat die gebruikers van hierdie metrieke aanduiders (metrics) selde weet hoe hulle ‘opmeet’ teen hul mededingers in die afwesigheid van normatiewe inligting. Indien menskapitaal as ‘n bron van ykmerk (benchmark) oorweeg kan word, moet die meting van menskapitaaleffektiwiteit ook normatiewe vergelykings toelaat. Die huidige studie het geouditeerde finansiële data vanaf McGregor BFA (2010) onttrek en die sentrale neiging en verspreiding van menskapitaalbeleggingsopbrengs van die maatskappye wat op die Johannesburgse Effektebeurs gelys is (N = 319), beskryf. Sodoende het dit ‘n stel ykmerke vir menskapitaaleffektiwiteit-metings daargestel oor die industrie- en maatskappy-grootte kategorieë heen, sowel as om reële veranderinge oor die finansiële jare (2006 – 2010) wat ondersoek is, te beskryf. Alhoewel Suid-Afrika met ‘n baie lae arbeidsmag produktiwiteitsvlak geag word in vergelyking met ander lande (Schwab, 2010 in World Competitive Report, 2010/2011), het die resultate getoon dat die algehele mediaan menskapitaalbeleggingsopbrengs ratio vir Suid-Afrikaans-gelyste maatskappye hoër (M = 3.03) was as die gepubliseerde syfers van die V.S.A., Europa en die Verenigde Koninkryk (PwC Saratoga, 2011). Hierdie beskrywende navorsing het ook die invloed van maatskappy-grootte (groot, medium of klein) en maatskappy-sektore (N = 42) op menskapitaaleffektiwiteit (soos geïndekseer deur die menskapitaal-beleggingsopbrengs) ondersoek. Geen statistiese beduidende verskille (p > .05) is tussen die menskapitaalbeleggingsopbrengs mediaan ratio’s oor die maatskappy-grootte kategorieë gevind nie, alhoewel daar noemenswaardige verskille in die mediaan van menskapitaalbeleggingsopbrengs oor die maatskappy-sektor kategorieë waargeneem is. Menskapitaalbeleggingsopbrengs het ook temporale skommelinge oor die studieperiode getoon, wat ekonomiese siklus-invloede reflekteer het, maar jaar-op-jaar veranderinge was groter indien die gemiddelde (mean) menskapitaalbeleggingsopbrengs gebruik was – mediaan menskapitaalbeleggingopbrengs het relatief stabiel van jaar-tot-jaar gebly. Uit hierdie navorsing word verskeie aanbevelings gemaak rakende die toepaslike gebruik van die menskapitaalbeleggingsopbrengs ykmerk-data. Die beskrywende studie lê ook ‘n vaste fondament vir toekomstige verklarende navorsing wat daarop gerig is om die voorafgaande veranderlikes (antecedents), korrelate en gevolge van menskapitaalbeleggingsopbrengs as ‘n indikator van menskapitaaleffektiwiteit te ondersoek. Die huidige studie dra tot die menskapitaalmaatstawweliteratuur by deur te demonstreer hoe menskapitaaleffektiwiteit indikatore vanaf geouditeerde finansiële resultate kan bereken word wat op die openbare domein beskikbaar is. Daardeur word gepoog om groter gebruik van menskapitaalrapportering in finansiële verslagdoeningstandaarde aan te moedig.

Empirical evidence indicates that companies that reduce information asymmetry by increased voluntary disclosures achieve several benefits, such as lower cost of capital, improved pricing, and liquidity of their shares. Despite the possibility of such benefits, many studies report varying degrees of voluntary disclosure behaviour that is attributable to various factors. Recent studies indicate that investors’ investment horizon has a significant effect on actions taken by management. Companies with predominantly short-horizon investors spend less on research and development, invest in shorter-term projects that are less profitable than longer-term projects, and are more likely to manipulate earnings to meet short-term earnings expectations. This study investigates whether investors’ investment horizon has an effect on the quality of companies’ information environment. Long-horizon investors should be familiar with their investee company’s risks and rewards, using both their own internal information gathering processes and the cumulative information disclosed by management over time. Moreover, over the course of a long-term relationship, they can become familiar with management’s capability to deliver long-term sustainable returns. Long-horizon investors should therefore be less concerned with short-term fluctuations of earnings and management’s public explanations and disclosures thereof. I hypothesise that higher (lower) proportions of long-horizon investors are associated with lower (higher) quality voluntary disclosure. The shareholder familiarity hypothesis was tested in this study, using an ordinary least squares regression. Voluntary disclosures were observed via the channel of companies’ websites. A checklist was compiled of best practices for online investor relations, and content analyses were conducted on the websites of 205 companies listed on the Johannesburg Stock Exchange. Shareholder familiarity was proxied by shareholder stability, measured over nine years. The stability measure was lagged by one year to create a temporal difference between the shareholder profile and disclosure behaviour. I found that companies with a profile of unstable investors that are larger, younger, dual-listed and have a Big4 auditor have higher quality online investor relations practices. The hypothesis of a negative association between shareholder familiarity and voluntary disclosure quality is therefore accepted. This study extends the theory on information asymmetry and voluntary disclosure by providing evidence supporting the argument that investor horizon is a predictor of voluntary disclosure quality. The dictum of more is better does not hold in all scenarios. It is important for financial directors and investor relations officers to establish the investment horizon profile of their respective companies’ shareholders before they embark on extensive disclosure programmes. / Financial Intelligence

This dissertation reflects the results of a study during which the 2006 annual reports of the top-40 JSE listed companies, were assessed for their disclosure of the required corporate governance statements. Content analysis was used to identify the information. The results obtained indicate that the majority of the JSE's top-40 listed companies adhere to good corporate governance disclosure practices. However, there are areas in which the non-disclosure of information was prevalent. These include the disclosure of information on the selection of external auditors and whistle blowing. Future research, employing sources such as SENS announcements, press releases, trading updates, cautionary announcements and websites together with annual reports should be conducted. / Financial Accounting / M.Com.

In South Africa, over-the-counter (OTC) bond options may be used in order to either hedge or speculate. However, since 2001, this market deteriorated significantly. The current research assessed the role of the local bond option market, reasons for the deterioration of the South African OTC bond option market, and how this bond option market could possibly be restored as a primary hedging instrument. The opinions of individuals operating in this market were obtained using a questionnaire. In the opinion of the respondents, wide bid–offer spreads, regulatory interferences and poor participation within this market caused market deterioration. The market could be restored as a hedging instrument if effective market integration exists, interbank trading regularly takes place, liquidity was enhanced, transparency increased and investor knowledge improved. Future research could focus on regulatory transformation, the types of derivatives used for hedging, and an assessment of appropriate continuous professional development interventions for investors. / Business Management / M.

MCom / Department of Accountany / The relationship between the Equity Market Risk Premium (MRP) and macroeconomic variables has been a subject of extensive discussion in the finance literature. The MRP is a central component of the main asset pricing models which are used to estimate the cost of equity which is mainly used in investment appraisal, performance measurement and valuation of equity assets. Past studies have identified inflation rate, interest rate, foreign exchange rate and political risk as the key macroeconomic variables that determine the size of the MRP. The test of the impact of these variables on the MRP have however been based mainly on data from developed countries and a few emerging countries. To the researcher’s knowledge, there are no studies that have investigated the impact of these macroeconomic variables on the MRP in South Africa. It is necessary to test the impact of these variables in the context of South Africa as these variables vary across countries. Using time series secondary data that was obtained from the SARB database, JSE database and World Bank database for the period 2002 to 2017, this study investigated the impact of these variables on the MRP in South Africa. A total of 192 observations per series of the inflation rate, interest rate, foreign exchange rate, political risk, JSE-ALSI and 91-days Treasury bill was used in the study. The data used were tested for possible misspecification errors that could arise from using a time series secondary data and the regression model was fitted using the Ordinary Least Square (OLS) estimator. The misspecification tests and models were both implemented on STATA 15 software. The results shows that inflation rate, interest rate and foreign exchange rate have a negative impact on the MRP whilst political risk has a positive impact on the MRP. Furthermore, the result shows that the inflation rate is the only variable amongst other variable tested that has a significant influence on the MRP for the study period. The study, therefore, concludes that inflation rate has the highest impact on the MRP in the context of South Africa. The study recommends that inflation rate should be monitored and kept within its target of 3-6% amongst other variables tested in order to increase investors’ confidence in the security market and also foster economic growth. The main limitations to the study were the limited data sources and insufficient funds. / NRF

We consider a mechanistic non-linear machine learning approach to learning signals in financial time series data. A modularised and decoupled algorithm framework is established and is proven on daily sampled closing time-series data for JSE equity markets. The input patterns are based on input data vectors of data windows preprocessed into a sequence of daily, weekly and monthly or quarterly sampled feature measurement changes (log feature fluctuations). The data processing is split into a batch processed step where features are learnt using a Stacked AutoEncoder (SAE) via unsupervised learning, and then both batch and online supervised learning are carried out on Feedforward Neural Networks (FNNs) using these features. The FNN output is a point prediction of measured time-series feature fluctuations (log differenced data) in the future (ex-post). Weight initializations for these networks are implemented with restricted Boltzmann machine pretraining, and variance based initializations. The validity of the FNN backtest results are shown under a rigorous assessment of backtest overfitting using both Combinatorially Symmetrical Cross Validation and Probabilistic and Deflated Sharpe Ratios. Results are further used to develop a view on the phenomenology of financial markets and the value of complex historical data under unstable dynamics.

In this paper, an attempt has been made to examine the evolution of corporate leverage of companies listed on the Johannesburg Stock Exchange (JSE) from 1994 to 2016. Analysis of the data set is organized around a sample of 126 listed companies across twelve sub-sector industries, namely, Banks, Financial Services, Life Insurance, Fixed Line Telecommunications, Nonlife Insurance, Health Care Equipment and Services, Pharmaceuticals and Biotechnology, Media, Technology Hardware and Equipment, Software and Computer Services, Electronic and Electrical Equipment and Support Services. 621 delisted companies were also briefly analysed to eliminate survivorship bias. Results of multiple regressions using two primary leverage measures and six commonly used determinants of capital structure were varied. Tangibility and growth were negatively related to debt while cost of debt was positively related to debt. Firm size, profitability and corporate tax rate yielded a varied relationship with corporate leverage. Only the growth capital structure determinant showed statistical significance. The overall findings indicate a rise in corporate leverage that coincides in tandem with major local and international economic events.

The impact of political and economic events on the asset pricing model described by the arbitrage pricing theory (APTM) was examined in order to establish if they had caused any changes in its specification. It was concluded that the APTM is not stationary and that it must be continuously tested before it can be used as political and economic events can change its specification. It was also found that political events had a more direct effect on the specification of the APTM, in that their effect is more immediate, than did economic events, which influenced the APTM by first influencing the economic environment in which it operated. The conventional approach that would have evaluated important political and economic events, case by case, to determine whether they affected the linear factor model (LFM), and subsequently the APTM, could not be used since no correlation was found between the pricing of a risk factor in the LFM and its subsequent pricing in the APTM. A new approach was then followed in which a correlation with a political or economic event was sought whenever a change was detected in the specification of the APTM. This was achieved by first finding the best subset LFM, chosen for producing the highest adjusted R2 , month by month, over 87 periods from 20 October1991 to 21 June 1998, using a combination of nine prespecified risk factors (five of which were proxies for economic events and one for political events). Multivariate analysis techniques were then used to establish which risk factors were priced most often during the three equal subperiods into which the 87 periods were broken up. Using the above methodology, the researcher was able to conclude that political events changed the specification of the APTM in late 1991. After the national elections in April 1994 it was found that the acceptance of South Africa into the world economic community had again changed the specification of the APTM and the two most important factors were proxies for economic events. / Business Leadership / DBL

As stakeholders start holding companies accountable for the non-financial impacts of their operations, it is increasingly recognised that the parties to whom companies are accountable extends beyond shareholders to include other stakeholders as well. Around the world, companies are responding to stakeholder demands by voluntarily reporting on their corporate social responsibility (CSR) performance. Unscrupulous companies may however, be tempted to use green-wash to make false claims relating to their CSR performance in order to reap the associated benefits. This information risk may be ameliorated through the independent assurance of CSR disclosures, enhancing the confidence of stakeholders in its veracity. Reporting companies usually voluntarily obtain independent assurance on their CSR performance. However, in South Africa, independent CSR assurance is a regulatory requirement for all JSE-listed companies, albeit on an ‘apply or explain’ basis. This thesis, which utilises a mixed methods research approach incorporating both qualitative and quantitative components, seeks to identify and understand the characteristics of the emerging independent CSR assurance phenomenon. In this regard, the empirical component of the study was conducted in three phases: in the first phase companies’ CSR disclosures and assurance reports are examined; in the second phase survey responses from companies are reviewed; and in the third phase interviews with CSR assurors are analysed. In this thesis, the extent to which companies provide independent assurance on their CSR disclosures is established; the providers of independent CSR assurance are identified; the reasons that companies select certain CSR assurance providers are explored; the reasons that companies provide independent assurance on their CSR disclosures are determined; the CSR assurance practices of the various CSR assurors are reviewed and compared; and the primary standards and/or frameworks used in CSR assurance engagements are identified. A conclusion is reached that although independent CSR assurance is a de facto mandatory requirement for JSE-listed companies, only 26% of the companies had their CSR disclosures independently assured. Despite its de facto mandatory nature, the study found that South African CSR assurance practices remain largely unregulated, resulting in a diversity of CSR assurors; utilising various assurance approaches, standards and practices. In this thesis, it is argued that these inconsistencies undermine the purpose of CSR assurance and reduce stakeholder confidence. It is accordingly proposed that the identified deficiencies could be addressed through the regulation of CSR reporting and assurance. An oversight/regulatory body should be established to prescribe the competencies that CSR assurors should possess; to develop appropriate CSR assurance engagement standards; and to clearly articulate the scope that CSR assurance engagements should cover; with which all CSR assurors should comply. / Auditing / D.
