The study is among the very few studies in Vietnam empirically examines internal control effectiveness as well as suggest the reference internal control components used in practice. To assess the internal control components and internal control effectiveness, a study of 236 external auditors who audited the operation of companies in Vietnam in 2011 was conducted. Even though some unexpected outcomes have incurred, “control environment” and “monitoring” are not supported in their relationship with “the reliability of financial report”; “information and communication” is not supported in the relationship with “the compliance with laws and regulations”, the empirical results indicate that all remaining internal control components (Control environment, risk assessment, control activities, information and communication, and monitor) have significant positive effect on internal control effectiveness which are also considered the company objectives: efficiency and effectiveness of operation, reliability of financial report, compliance with laws and regulations.
Key words: Internal control components, Internal control effectiveness. TIEU LUAN MOI download : skknchat@gmail.com 2 CHAPTER 1: INTRODUCTION 1. Introduction This chapter represents general introduction to the study including research issues, research objectives and research questions applied in this study. In addition, this chapter also addresses the methodology to be used and the scope of the study.
Background to the research Understanding the concept of internal control is essential for developing an understanding of its impact on the performance of organization (Lembi, 2006). In the world, internal control is traditionally proposed as “internal check”. Its definition was then developed as “process activities” to enable management to deal with rapidly growth. However, there was no official regulation in force to require companies set up internal control to prevent risk and protect their business.
After many scandals incurred in financial perspective 21st century, Sarbanes-Oxley Act of 2002 (SOX) requires management of all public firms to issue internal control report, take responsibility for maintaining an adequate internal control, and make concerning to its effectiveness (PCAOB,2004). The external auditors are also responsible for auditing management assertions as to the effectiveness of the internal control and they have to give their own, independent conclusion (Ramos 2004, 75). Meanwhile, the reference groups like suppliers, investors and customers have also focused more on quality of company’s reporting and accountability (Rittenberg and Schwieger 2001, 172). An effective internal control system therefore has played a critical role in a firm’s success.
It helps organization management to keep the company on profitability goals, to achieve its mission, and to response to its risks of business (COSO, 1994). However, how to develop an optimal internal control framework for all companies is still further research. TIEU LUAN MOI download : skknchat@gmail.com 3 In 1994, Committee of Sponsoring Organizations (COSO) proposes Internal Control framework consists of five interrelated components but states that the need for control system and control effectiveness may vary according to a firm’s characteristics. Donaldson (2001) indicates that the design of management control system depends on the organization’s context, a fit between the organization’s context and internal control components leads to better internal control effectiveness.
However, the evidence of the actual performance of an internal control within the organizational environment is almost non-existent, and the topic relatively unexplored by researchers (Kitnney, 2000). Consequently, in recent year, many researchers (Chenhall 2003, Gerdin 2005, Jokipii 2009) have attempted to explain internal control effectiveness by examining its designs. With regard to Vietnam, there is almost non-existent research about internal control and its effectiveness. Thus, this study is motivated to propose an internal control framework, the internal control effectiveness definition for companies operated in Vietnam reference as well as to explore the effect of existed internal control components on internal control effectiveness.
Research problems In Vietnam, learning lessons from financial scandals highlight that those charged with governance in companies do not properly identify, evaluate and respond to the firm risks. They do not set up strong internal control enough to protect their operation. Even though Vietnam is now one of the most strongly developing of economic growth in Asia after had joined in WTO at the end of 2006, it has recently been beset by inflation, a trade deficit, the stock market slump and affect the negative results to enterprises in Vietnam. Thus, this is necessary time for companies in Vietnam to renew and restructure their operation (Vietnam News, 2012).
However, how to restructure their operation is still challenge to management in companies. TIEU LUAN MOI download : skknchat@gmail.com 4 As mentioned above, there is still lack of practical research on internal control sector. The problem is therefore to be addressed. This study concentrates to the internal control components, internal control effectiveness and to explore the effect of internal control components on internal control effectiveness of firms in Vietnam.
Research objectives A research objective is the research version of a business problem. Objectives explain the purpose of the research in measurable terms and define standards of what the research should accomplish (Zikmund 1997, 89). In solving the research problem mentioned previously, this study has the following objectives: 1) Investigate the relationships of internal control components and the efficiency and effectiveness of operation. 2) Investigate the relationships of internal control components and the reliability of financial report.
3) Investigate the relationships of internal control components and the compliance with laws and regulations. Research questions The study is conducted to explore the relationship between internal control components and its observed effectiveness in companies. It is examined to understand whether internal control components such as control environment, risk assessment, control activities, information and communication, monitoring have relationship to the internal control effectiveness which comprise the efficiency and effectiveness of operation, the reliability of financial report, the compliance with laws and regulations. The research questions therefore concentrate on internal control components, the internal control effectiveness assessment as well as the relationship between them.
TIEU LUAN MOI download : skknchat@gmail.com 5 Research question 1: Is the efficiency and effectiveness of operation positively related to the internal control components? Research question 2: Is the reliability of financial report positively related to the internal control components? Research question 3: Is compliance with laws and regulations positively related to the internal control components? 1. Research methodology and scope The object of this research was external auditors who audited the operation of companies in Vietnam. Qualitative method: The author used the qualitative method to carry out group discussions with six experienced external auditors. The purpose of this step is to adjust and amend the translated questionnaire suitable with the subject and purposes of the study.
Quantitative research was used to explore the relationship between internal control components and internal control effectiveness from the external auditor’s perspective. The quantitative model was adopted from the previous research of Jokipii (2009). The author used data analysis tools to implement the research such as: descriptive statistics, multiple regression models with SPSS version 16. TIEU LUAN MOI download : skknchat@gmail.
