Business leaders remain exposed to financial and accounting fraud as well as loss of profitability, despite the dictates of the SOX Act of 2002. The most challenging aspect of corporate management is the unexpected nature of an emerging, existing, or an inherent financial risk. Guided by the evolution of fraud theory, this exploratory case study's purpose was to identify and explore the financial management strategies that corporate financial managers need to adequately protect investors. Twenty participants from a population group of corporate auditors of Fortune 1000 corporations within 70 miles of Columbus, Ohio provided input for this study. Data from the interviews were analyzed through coding, reviewing, categorizing, and combining common statements. The research findings included themes of knowledge and types of risks; the impact of financial fraud and risks on investment; the impact of accounting, auditing, and financial reporting standards; as well as financial management training to minimize audit expectations. These themes formed the focus of exploring the financial management strategies that corporate financial managers need to adequately protect investors and investments. In addition to the antifraud measures, financial managers may detect and control inherent risks in emerging opportunities for positive social change that includes enhanced knowledge in diversification of investments, an increase in economic resources, economic growth, and greater employment in the United States.

<p>This thesis explores the following three important issues in the field of corporate finance: window dressing in corporate cash holdings, market effects of SEC regulation of short-term borrowing disclosure and market response to dividend change announcements by unregulated versus regulated firms.</p> <p>First, I find strong evidence of upward window dressing in cash holdings by U.S. industrial firms during the fourth fiscal quarter. This behavior is robust to several controls and a December year-end dummy. Further cross-sectional analysis reveals that the window dressing is sensitive to firm size and level of information asymmetry. I also find that firms manipulate discretionary accruals to dress up fourth quarter cash, perhaps to gain favourable credit terms on issuing short-term debt.</p> <p>Second, I use portfolios of financial and non-financial SEC registrants to examine the market reaction to proposed SEC short-term borrowing disclosure regulation. Using event study methodology, I find that the market reaction is positive and significant at the announcement date and negative and significant at the voting date. Overall, I observe a positive market reaction, indicating the usefulness of the disclosure from the vantage point of users. The results for various subsets confirm the expectations and suggest that a “one-size-fits-all” approach to regulation is undesirable.</p> <p>Finally, I use large samples of dividend increase and decrease announcements for the period 1960 to 2010 in order to compare stock price reactions of unregulated and regulated firms. I observe a stronger market reaction to the dividend increase announcements of unregulated firms compared to those of regulated firms after controlling for firm characteristics, market factors and contemporaneous earnings announcements, a result consistent with the dividend signaling hypothesis and uniqueness argument for regulated firms. However, I find that the market reaction to dividend decrease announcements is similar for unregulated and regulated firms. The cross-sectional analysis further confirms that the stronger stock price reaction to dividend increase announcements of unregulated firms is associated with the level of information asymmetry.</p> / Doctor of Philosophy (PhD)

This paper studies the price fluctuation from 2010 to 2016 of two major assets in China: real estate and stock. Equity price is found to Granger cause stock price while the reverse relationship is significant but less strong. The paper then studies whether the nature of the correlation depends on the type of city under consideration. This is achieved by grouping 25 cities into four city tiers based on their level of economic developments and conducting a linear causality test on each city tier. Housing price in first tier cities is found to be much more significantly correlated with stock price. Larger and more developed cities tend to have a stronger correlation with stock than smaller and less developed ones. In addition, the paper also studies the impact of the Chinese government’s recent home purchase restriction on the relationship between the two asset classes. However, the results are contradictory and are not consistent with expectation. The lack of significant results could be contributed to the inherent limitation of our data, as well as the complicated and sometimes confusing policy announcement mechanisms in China.

Intangible assets have been the increasingly dominant primary source of market value creation. This paper investigates the relationship between leverage and various intangibles related ratios. An empirical analysis is conducted to quantitatively understand the impact that these ratios have on leverage. The results show that intangible assets have a clear significant positive relationship with leverage. Accounting based principles are used to provide reasoning behind the results, which include the difference in impact that internally generated intangible assets and acquired intangibles have on leverage.

Playing has been part of people's lives since the beginning of time. However, play does not take place in silence (isolated from speech and sound). The games people play allow them to interact and to learn through experiences. Speech often forms an integral part of playing games. Video games also allow players to interact with a virtual world and learn through those experiences. Speech input has previously been explored as a way of interacting with a game, as talking is a natural way of communicating. By talking to a game, the experiences created during gameplay become more valuable, which in turn facilitates effective learning. In order to enable a game to “hear", some issues need to be considered. A game, that will serve as a platform for speech input, has to be developed. If the game will contain learning elements, expert knowledge regarding the learning content needs to be obtained. The game needs to communicate with a speech recognition system, which will recognise players' speech inputs. To understand the role of speech recognition in a game, players need to be tested while playing the game. The players' experiences and opinions can then be fed back into the development of speech recognition in educational games. This process was followed with six Financial Management students on the NWU Vaal Triangle campus. The students played FinMan, a game which teaches the fundamental concepts of the “Time value of money" principle. They played the game with the keyboard and mouse, as well as via speech commands. The students shared their experiences through a focus group discussion and by completing a questionnaire. Quantitative data was collected to back the students' experiences. The results show that, although the recognition accuracies and response times are important issues, speech recognition can play an essential part in educational games. By freeing learners to focus on the game content, speech recognition can make games more accessible and engaging, and consequently lead to more effective learning experiences. / MSc (Computer Science), North-West University, Vaal Triangle Campus, 2014

Bakgrund: Controller är ett yrke som kom till Sverige på 1970-talet och det har sedan dess varit svårt att hitta en generell definition på vad en controllers huvudsakliga arbetsuppgifter är. Undersökningar med controllers har visat att yrket är i ständig utveckling. Litteratur inom området hävdar att en controller bör vara utbildad inom ekonomi och generellt sett arbeta med ekonomistyrning. Arbetsuppgifterna som controllers har varierar dock stort och problemet är att företag idag använder titeln controller som en fin titel och för att kunna forma rollen själva då den är så pass svårdefinierad. Syfte: Uppsatsens syfte är att definiera den typiska controllerns bakgrund samt dennes främsta arbetsuppgifter. Uppsatsen syftar även till att skapa förståelse för hur utvecklingen har sett ut inom yrket hittills samt skapa en bild av vilka arbetsområden controllers tror kommer kräva mer av deras tid i framtiden. Metod: För att uppfylla uppsatsens syfte har en kvantitativ studie gjorts där insamling av data har gjorts via en enkät. Vidare har en abduktiv forskningsansats använts samt ett hermeneutiskt synsätt. Enkäten skickades till cirka 70 olika organisationer i Sverige och totalt medverkade 148 respondenter. Slutsats: I slutsatsen framkom det att en controller idag oftast har någon form av ekonomisk bakgrund och att deras främsta arbetsuppgifter har utvecklats mot en mer klassisk controllers arbetsuppgifter. Respondenterna tror att arbetsområden som kommer ta mer av deras tid i framtiden är sådana som kan kopplas till den klassiska controllerrollen. I undersökningen framgick att en controller gör väldigt många olika saker och vi, precis som många innan, kom fram till att yrkesrollen är svårdefinierad. / Background: The Controller is a profession which came to Sweden in the 1970s and it has since then been difficult to find a general definition of what the main duties of a controller are. Studies about controllers have shown that the profession is in constant development. Literature in the field claim that a controller should be trained in economics and generally work with financial management. The tasks of controllers vary greatly and the problem is that companies today are using the title controller as a exclusive title and to be able to shape the role themselves since it is so difficult to define. Objective: The purpose of this study is to define the typical controller's background and his or her primary duties. The paper also aims to create an understanding of how the profession has developed to date and to see which duties the controllers belive will occupy more of their time in the future. Method: To meet the purpose of the paper a quantitative study were performed where data collection has been done through a survey. The survey was sent to approximately 70 different organizations in Sweden and involved a total of 148 respondents. Conclusion: This study shows that a controller today usually have some sort of financial background and that their primary duties have evolved towards the duties of a classical controller. Respondents believe that the duties that will take more of their time in the future are those that can be linked to the classic controller role. The study revealed that a controller does many different things, and we, like many before, concluded that the professional role is hard to define.

This paper examines the role that gold and other precious metals play in portfolio construction as hedges and safe havens in comparison with the Volatility Index (VIX), a derivative of market volatility. Gold has long been considered to be among the best assets for reducing portfolio volatility due to its lack of correlation with the overall market. However, the major finding of this paper is that while gold and the other precious metals do serve in this role to varying extents, the VIX performs this function far better. Both econometric and portfolio analyses reveal that the VIX improves overall portfolio performance to a greater extent, and most importantly serves as an effective safe haven relative to the market.

Momentum investing is the process of buying stocks that have performed strongly in the past and shorting historically weak performers. Past empirical research has consistently shown momentum to generate significantly positive returns on a zero-cost strategy. We show that momentum performs well regardless of the specific time horizon used in formation and investment and motivate a one month gap between forming the portfolio and investing in it. Consistent with literature, we find momentum crashes–months where momentum’s profitability dramatically reverses–and demonstrate that momentum crashes occur across all time horizon variations in momentum. Lastly, we show that the momentum portfolio during crash months is not marked by clustering in specific industries, and that the momentum premium can- not be explained by risk from regulatory uncertainty of the financial services industry.

This empirical study employs a different methodology to examine the change in wealth associated with mergers and acquisitions (M&As) for US firms. Specifically, we employ the standard CAPM, the Fama-French three-factor model and the Carhart four-factor models within the OLS and GJR-GARCH estimation methods to test the behaviour of the cumulative abnormal returns (CARs). Whilst the standard CAPM captures the variability of stock returns with the overall market, the Fama-French factors capture the risk factors that are important to investors. Additionally, augmenting the Fama-French three-factor model with the Carhart momentum factor to generate the four-factor captures additional pricing elements that may affect stock returns. Traditionally, estimates of abnormal returns (ARs) in M&As situations rely on the standard OLS estimation method. However, the standard OLS will provide inefficient estimates of the ARs if the data contain ARCH and asymmetric effects. To minimise this problem of estimation efficiency we re-estimated the ARs using GJR-GARCH estimation method. We find that there is variation in the results both as regards the choice models and estimation methods. Besides these variations in the estimated models and the choice of estimation methods, we also tested whether the ARs are affected by the degree of liquidity of the stocks and the size of the firm. We document significant positive post-announcement cumulative ARs (CARs) for target firm shareholders under both the OLS and GJR-GARCH methods across all three methodologies. However, post-event CARs for acquiring firm shareholders were insignificant for both sets of estimation methods under the three methodologies. The GJR-GARCH method seems to generate larger CARs than those of the OLS method. Using both market capitalization and trading volume as a measure of liquidity and the size of the firm, we observed strong return continuations in the medium firms relative to small and large firms for target shareholders. We consistently observed market efficiency in small and large firm. This implies that target firms for small and large firms overreact to new information resulting in a more efficient market. For acquirer firms, our measure of liquidity captures strong return continuations for small firms under the OLS estimates for both CAPM and Fama-French three-factor models, whilst under the GJR-GARCH estimates only for Carhart model. Post-announcement bootstrapping simulated CARs confirmed our earlier results.
