Based on the above mentioned theories and practice, the thesis on “The impacts of characteristics of corporate governance on the implementation of conservatism in accounting of listed e
Trang 1CHAPTER 1 INTRODUCTION 1.1 Rationales
Conservatism is one of fundamental accounting principles Also, it is a commonly required criteria during the
accounting process The performance of this principle puts an impact on the determination of value of items shown in the
balance sheet, which, consequently affects honesty, reliability and usefulness of accounting information The importance of
this principle was recognized by International Accounting Standards Board (IASB) through its inclusion of conservation in
the conceptual framework as well as its requirement of huge conservation reflection in specific items of International
Financial Reporting Standards (IFRS)
A certain number of previous studies revealed the avantages of implementing conservatism in accounting such as
allowing management board to early identify projects with negative present value (Ball, 2001), increasing future investment
opportunities (Garcia Lara et al, 2009), mitigating managerial opportusim (Watts, 2003; Chen et al, 2007), decreasing
earnings management (Watts, 2003), and improving enterprises’ value (Watts and Zuo, 2012), etc However, in reality,
enterprises might take advantage of conservatism principle in accounting as an approach to make up subjective information
in the balance sheet serving different aims like establishing sinking fund “on purpose”, exceeding reserves, and consciously
delaying interest recognition, etc In addition, the imbalance in recording would influence the focus of accounting
information, resulting in conflicts about the impact of implementing conservatism Therefore, IASB excluded conservatism
from the conceptual framework in the edited version in 2010 However, this change caused controversies due to careless
assessment of transactions and uncertain events of enterprises Noticeably, despite the non-existence of conservatism in the
conceptual framework, the requirement for this criteria is still compulsory in recording, determining the value and
announcing information (IAS 2, IAS16, IAS 19, IAS 36, IAS 37, IAS 39, IAS 40, IFRS 2, IFRS 4, IFRS 5, IFRS 7, IFRS
9) Thus, in the draft of IASB’s conceptual framework amendment in 2015, the principle of conservatism was reincluded
Based on the importance of performing conservatism in accounting as well as its negative and positive impacts, it is
essential to apply an observatory mechanism for enterprises’ internal and external implementation of this principle From
the perspective of internal performance, corporate governance’s features are regarded as one of influencing factors on the
implementation of conservatism in accounting Corporate governance is derived from the separation between corporate
control and ownership as well as concentration on solutions to arising problems related to principle-agent, prevention and
mitigation of owners’ abuse of position and power to use corporate assets and take business opportunities for personal/
others’ purposes or lose resources under the control of corporate Good corporate governance would help management
board to make decisions and take actions compatible with mutual spirit and benefits of investors, shareholders and relevant
stakeholders There have been numerous studies demonstrating that establishment of good corporate governance
mechanism would have positive impact on the implementation of conservatism in accounting (Beekes et al (2004), Lim
(2011), Lara et al, (2009), Ahmed and Duellman (2007)….)
In Vietnam, characteristics of corporate governance are related to those of Board of Directors, Board of Supervisory,
Board of Management and capital owning structure of relevant organizations and individuals, etc Each characteristic has its
own influence on the observation of business activities, then, it would have an impact on the effectiveness of observing the
implementation of conservatism in accounting Therefore, the impact of corporate governance characteristics on the
implementation of conservatism in accounting is one of the huge concerns in this thesis, which is expected to be clearly
explored

Trang 2CHAPTER 2 THEORETICAL FRAME AND LITERATURE REVIEW ON IMPACTS OF CORPORATE
GOVERNANCE CHARACTERISTICS ON THE IMPLEMENTATION OF ACCOUNTING
CONSERVATISM 2.1 General theories on accounting conservatism
Prudence/conservatism is a common principle (convention), which appeared in accounting long time ago and has
impacts on both theory and practice of accounting Sterling (1967) described accounting conservatism (ACC) as ‘the oldest
and might be the most common principle in accounting pricing’ May (1943a) defined ACC as one of the oldest accounting
practices ACC is has been a section and a part of accounting development for centuries
2.1.1 History of accounting conservatism
ACC is an instruction for accountants and managers to estimate and record information in uncertain situations Level
of ACC implementation depends on subjective purposes of managers and accountants As a consequence, there would be
both negative and positive impacts of ACC implementation
2.1.2 Models for accounting conservatism measurement in enterprises
2.1.2.1 Model by Basu (1997)
2.1.2.2 Model by Khan & Watts (2009)
2.1.2.3 Model by Ball and Shivakumar (2005)
2.1.2.4 Model by Feltham & Ohlson (1995), Beaver and Ryan (2000)
2.1.2.5 Model by Givoly and Hayn (2000)
2.1.2.6 Model by Ahmed & Duellman (2007)
2.2 Overview on theories about corporate governance
2.2.1 The root and definition of corporate governance
Corporate governance (CG) derived from the separation of ownership from control in public companies (joint stock companies) Currently, there is a quite large number of studies on CG and different concepts related to this issue Followings are some widely accepted concepts
In this thesis, CG is defined based on the concept given by Organization for Economic Co-operation and Development (OECD, 2004) In particular, CG covers a consistent establishment of internal measures to control and orient enterprise activities So, characteristics of CG are comprised of structures of Board of Directors, Board of Management, Board of Supervisory, that of ownership, etc in the enterprises
2.2.2 Content and characteristics of corporate governance
Currently, there are more than 200 sets of regulations for CG for more than 72 countries and territories (IFC, 2010), most of which focus on the role of Board of Supervisory or Board of Directors, some of which are internationally used
In Vietnam, current valid law in CG in listed enterprises is the Decree 71/2017/NĐ-CP ‘Corporate governance instructions applied to public companies ’, which is in place of the Circular 121/2012/TT-BTC ‘Corporate governance regulations applied to public companies’
2.3 Literature review on impacts of gorporate governance characteristics on the implementation of accounting conservatism
Worldwide studies on the impacts of CG characteristics on the implementation of ACC concentrated on chacracteristics of Board of Directors, Board of Supervisory and ownership (Beekes et al, (2004), Ahmed & Duellman (2007), Xia & Zhu (2009), Lim (2011), Ahmed & Henry (2012), Kootanaee et al, (2013), Jarboui (2013), Yunos et al, (2014), Boussaid et al, (2015), Mohammed et al, (2016), Nasr and Ntim (2017)…) Characteristics of Board of Directors cover: Scope of Board of Directors, double roles of chairman and CEO, independence of memners in the board, accounting and financial expertise of members in the board Characteristics of Board of Auditing, Board of Supervisory cover: the appearance of auditing committee, accounting and financial expertise of members of the committee Those of ownership cover: ownership of Management Board and that of the State
In Vietnam, there has been no research on impacts of CG characteristics on the implementation of ACC
2.4 Background theories for research in the impacts of CG charactersitics on the implementation of accounting conservatism
2.4.1 Theory on Asymmetric Information
According to asymmetric information, the failure between information provision and receipt would cause disadvantages Regarding the case of stock market, information supplier is the management board, representing for shareholders; information receiver includes shareholders, investors, credit organizations, state authorities, etc In fact, information failure is popular in Vietnam stock market in particular and other stock markets in general In order to reduce this asymmetric information in joint stock companies, it is necessary to build up an effective observation mechanism through enhancing the employment of corporate governance principles, and establishing characteristics of Board of Directors, Board of Supervisory and internal audit At the same time, the stock market’s management board should provide investors with adequate, useful and timely information Especially, there must be no supply of overpositive information about the company’s financial status through ACC application
2.4.2 Agency Theory
Agency theory is one of significant and fundamental theories, which is related to different aspects of CG, especially responsibilities of parties The conflicts of benefits between principals and agents might be rooted from either differences in their objectives or information failure between managers and other parties
Agency theory suggested that more independent the number of members of management board is, the higher effectiveness of observation is (Nicholson and Kiel, 2007) Then, the company would reduce agency cost, and benefits of
Trang 3shareholders would be greater According to this theory, creating and presenting financial statement have two different
purposes: regarding shareholders, they reflect the observation of effectiveness of managers; regarding managers, they show
managers’ persuasion for the best actions (Watson et a, 2002) Therefore, it is essential to establish a suitable observation
system for management board in order to protect benefits of shareholders and ensure quality financial statement from
suppliers
2.4.3 Stakeholder theory
Stakeholder theory stated that besides shareholders, there are other relevant parties to the operation of the enterprises,
covering government agencies, political organizations, trade associations, trade union, community, related companies,
potential customer, and public (including potentail investors) Acording to Zingales (2000), a company should not simply
be a complex of available participants in the market, in fact, it should be a unique combination among paticipants Based on
ethical perspective, enterprises are responsible for equality among relevant parties When there is any conflict of benefits
among them, enterprises must try to obtain optimal balance
2.5 Research “gap”
Firstly, at present, there are various studies on contents related to accounting conservatism However, in Vietnam,
some authors only cover certain aspects of implementing accounting conservatism such as creating preserves, recording
potential debt, etc So, this thesis provides a comprehensive research into accounting conservatism of non-financial
companies listed on Vietnam stock market
Secondly, in Vietnam, there has been no study measuring accounting conservatism as well as its implementation
Then, based on advantages and disadvantages of each measuring model, and specific features of listed companies on
Vietnam stock market; this thesis determines a suitable model to measure the implementation of accounting conservatism
Thirdly, studies on impacts of CG characteristics on ACC implementation have been carried out developed countries
like England, America, France, Australia or other developing ones with long-term, stable operation of stock market and
complete legislation like Malaysia Moreover, research findings about influences of CG charactersitics on ACC
implementation in the world have notreached an agreement in terms of impact of Board of Director size, double positions of
both chairman and CEO, impact of ownership structure, etc So, it is essential to supplement empirical studies on these
aspects This thesis is the first empirical research in Vietnam about impacts of CG characteristics on the implementation of
ACC
Forthly, based on the characteristics of joint stock companies and those of stock market in Vietnam, there must be
addition to studies on impacts of state capital on the implementation of ACC This issue was discussed in the case of China,
but, there was not statistical implication Therefore, this thesis looks into the impacts of state-owned capital on the
implementation of ACC in listed companies on Vietnam stock market
Fifthly, in Vietnam, except for regulations on Board of Supervisory (Law on Enterprise, 2014, Circular 121/2012 on
Corporate Governance) , there has not been any compulsory legislative document about the establishment of auditing
committee in listed companies Regulations on Supervisory Board cover number of board members, accounting expertise of
these members, and independence of these members Based on previous studies, most listed companies have followed
regulations on the number of Supervisory board members (3 to 5 people) However, regulations on specialization and
independence of these members have not been strictly obeyed Due to limited data about independence of Supervisory
board members, this thesis focuses on characteristics of members with accounting and finance specialization and determines
the impact of these characteristics on ACC implementation
CHAPTER 3:
SCIENTIFIC HYPOTHESES AND RESEARCH METHOD 3.1 Development of scientific hypotheses regarding characteristics in Corporate Governance influencing the
implementation of conservatism in accounting
3.1.1 Scientific hypotheses
Hypothesis 1: The scale of corporate governance positively affects the implementation of accounting conservatism concept
(ACC)
Hypothesis 2: The double position of CEO and Board Chairman negatively affects the implementation of ACC Hypothesis 3: The higher ratio of non-executive board members in the total number of board members, the more
effective the implementation of ACC will be
Hypothesis 4: The number of board members with accounting and finance expertise positively influences the
implementation of ACC
Hypothesis 5: The ratio of members in the supervisory board with accounting and finance expertise positively
influence the implementation of ACC
Hypothesis 6: Listed companies with Board of Directors being the majority shareholders negatively influence the
implementation of ACC
Hypothesis 7: Companies with capital ownership of Government being more than 50% has the lower rate of
deploying ACC compared with firms with capital ownership of Government being below than 50%

CHAPTER 5 DISCUSSION OF RESEARCH RESULTS, RECOMMENDATIONS AND CONCLUDING REMARKS 5.1 Analysis and comparision of regression results in different models
5.2 Discussion of research results
Hypothesis 1 was disproved: The scale of Board of Directors does not have statistical significane with the
implementation of ACC This result is homogeneous with the outcome of research by Ahmed & Duellman (2007), Kootanaee et al (2013), Mohammed et al (2016), Yunos et al (2014)
Hypothesis 2 was approved: In companies where the Board Chairman was also the CEO, the ACC implementation’s
degree was 0,909 points lower than companies without the concurrent employment of these two positions This result is homogeneous with the outcome of research by Malaysia and Roslinda Lim (2011) in Australia that states The concurrent employment of CEO and Board Chairman negatively affects the deployment of ACC
Hypothesis 3 was disproved: There was no statistical significance in the relationship between the ratio of
non-executive board members an the implementation of ACC This result is homogeneous with the outcome of research by Kootanaee and partners (2013), Boussaid et al (2015), Xia & Zhu (2009)
Hypothesis 4 was approved: If the ratio of board member with accounting and finance expertise increases by 1%, the
ACC deployment’s degree increases by 2,048 points This result is homogeneous with the outcome of research by Yunos et
al (2014) in Malaysia
Hypothesis 5 was approved: The ratio of members in the supervisory board with accounting and finance expertise
has a positive relationship with the ACC implementation with the statistical significane being 10% This result is homogeneous with the outcome of research by Madah & partners (2016)
Hypothesis 6 was approved: Listed companies with majority shareholders being Board of Directors have the degree
of ACC implementation being 1,576 points lower than companies with majority shareholders not being Board of Directors
at the significance being 1% This result is homogeneous with the outcome of research by Donglin Xia & Song Zhu (2009)
in China, Anis Jarboui (2013) in France và Mohammed et al (2016) in Malaysia Currently, Vietnam does not have regualtions on ownership’s percentage of Board of Director or the General Director
Hypothesis 7 was approved: Companies with capital ownership of Government being more than 50% has the lower
rate of deploying ACC compared with firms with capital ownership of Government being below than 50% Previous research by Cullinan & et al (2012) in China and Mohammed et al (2016) in Malaysia also investigated the effect of the State’s ownership on the ACC deployment but no relationship with statistical significane was found
5.3 Some recommendations on the ACC implementation in companies listed in Vietnam stock market
5.3.1 Recommendations for companies
Firstly, companies are require to enhance knowledge in terms of accounting standards and principles in order to correctly apply them and ensure the information provided by accountants being useful, comparable and reliable
Secondly, results of empirical research are one of references that companies can use to self-evaluate the influence of factors in corporate governance on the ACC deployment:
- In addition to maintaining the quantity of board members, companies are required to concentrate on each individual’s responsibily in the board in order to enhance the supervision of firms’ activities
- Prohibit the concurrent employment of Board Chairman and CEO to avoid the usage of ACC as a tool to adjust profits or the intentional non- implementation of ACC
- Companies are required to ensure the Board’s structure with the appropriate number of members with profession and knowledge in the firm’s operation
Trang 7- Companies and shareholders are requested to raise their awareness of supervisory board’s role and promote the
rights and tasks of this board
- In the process of voting for Management Board by Board of Directors, it is necessary to pay detailed attention to the
ownership of board members to control the independence of the board as well as ensure the shareholders’ rights Board of
Directors are required to frequently supervise the volatility in buying, selling and holding shares of senior members in order to
prevent them take advantage of company’s information or use personal relations to control the shares
5.3.2 Recommendations for State administrative agencies
Ministry of Finance is required to provide strict regulations on the use of accounting estimates to limit the
subjectivity of compaies in this issue Additionally, it is essential to request firms to clearly state the content of these
accounting estimates, its impact on the financial statement published by companies Stricter regulations on the functions
and duties of the Board of Directors are required to be promulgated to ensure the effective performance of the Board of
Directors
It is necessary to improve the qualifications of the Supervisory Board as well as its independence of the Supervisory
Board to create a positive working environment The State Securities Commission needs to impose penalties for listed
companies that fail to fully comply with the regulations on the ratio of members in Supervisory Board with appropriate
profession The State is required to request companies to publish the report on Supervisory Board in the annual report
5.3.3 Recommendations for investors
The implementation of ACC will affect the financial statement published by companies as well as investors'
decisions When implementing ACC, profit information will be affected and more volatile which leads to the reduction in
the forecast ability Therefore, when analyzing the company's financial situation, investors need to consider financial
indicators (especially profit and cash flow) according to series of time periods, compare and analyze their values throughout
quarters and years as well as the influence of factors on the value modification of these indicators Concurrentlt, investors
are required to understand the impact of implementing ACC to properly assess the financial situation of companies in order
to make sound investment decisions
5.3.4 Recommendations for education and training institutions
Paying attention to the role of education and training institutions as well as organizations in perfecting the corporate
governance mechanism by organizing short-term training courses, science and profession seminars to help companies'
managers and policy makers have a better understanding of corporate governance's role and the application of its priniciples
according to international practices in order to improve the quality of corporate governance in Vietnamese enterprises
5.4 Contributions of the thesis
- The thesis presented the history of conservatism principle, the effect of the implementation, the measurement
models of the principle implementation, the relationship between corporate governance and the implementation of prudent
principles in accounting In addition, based on assessing the advantages and disadvantages of each model that previous
studies have used to measure the degree of implementation of the prudent principle in accounting, the author selects the
most appropriate method complying with conditions and characteristics of companies listed on Vietnam stock market
- The thesis provides reliable empirical evidence on the status quo of infulence of factors in corporate governance on
the implementation of ACC in companies listed on Vietnam stock market during the period of 2012 to 2016
5.5 Limitations of the thesis
Firstly, the scope of the thesis is 5 years lasting from 2012 to 2016 with a research population of 528 listed
companies on both Hanoi and Ho Chi Minh Stock Exchange If the time period for research were longer with updated data,
a more general view of the ACC implementation in companies would be produced
Secondly, although the thesis analyzed and evaluated the status quo of ACC implementation in companies according
to their industry and years of operation, the empirical research results on the impact of corporate governance's factors on the
implementation of ACC provided an general evaluation for the whole population Therefore, the thesis has not yet to consider differences in the degree of influence on the industry of each company
Thirdly, the thesis has yet to analyze the regulations of some countries in the world regarding where to implement ACC (in what contents or degree) in order to have experience in applying conservatism in accounting in Vietnam
CONCLUSION
In order to provide useful and reliable informationabout enterprises’ financial status, managers should follow accounting standards and principles Pre-recording potential loses in the future might help enterprises actively tackle possible changes and stalize business Then, information of financial statement would be more helpful to users
Regarding the implementation of ACC, accounting practioners should use accounting estimations and base on subjective considerations to evaluate and record the status However, according to Watts & Zimmerman (1990), if managers and generators of financial statement provided exceeding estimations based on their subjective intentions, there might be benefit adjusting behaviors Also, if enterprises consciously disobey the principle and provide accounting estimations lower than reality in order to disclose benficial information as their own expectations, the implementation of the principle would become a tool for managers to control their benefits
There are numerous factors affecting the implemention of ACC in enterprises, of which, characteristics of CG is an important aspect When there is an improvement in quality of CG, there will be an enhancement of observation related to complete and comprehensive implementation of ACC Improving operation as well as responsibilities of Board of Directors, Supervisory Board and determining suitable ownership structure would help to control benefit management, and supervise the implementation of current regulations for enterprises in accounting and finance area
This thesis studied impacts of CG characteristics on ACC implementation in non-financial firms listed in Vietnam stock market in the period of 2012 – 2016 Based on the literature review, this thesis researched effects of characteristics of Board of Directors, Board of Supervisory and ownership on ACC implementation At the same time, according to an analysis into advantages and disadvantages of models used for the measurement of ACC implementation level, this thesis chose the model by Ahmed & Duellman (2007) This thesis applied regression with three methods of ordinary least square (OLS), fixed effect model (FEM), random effect model (REM) and used appropriate assurance to select the most suitable model in order to provide empirical results with highest reliability, which was FEM Among 7 characteristics of CG in this thesis, 5 of which namely ‘double positions’ (DUAL), ‘members of Board of Directors with accounting and finance expertise’ (BO_EXPERT), ‘members of Board of Supervisory with accounting and finance expertise ’ (CO_EXPERT),
‘captial ownership of Board of Mangers’ (OWN_MAN) and ‘capital ownership of Government’ (OWN_GOV) were proved
to have relationship with ACC implementation in terms of statistical meaning
Results of empirical study of this thesis added findings to previous ones about the relationship between CG and ACC implementation in developing countries like Vietnam in order to provide more understandings about reality of implementing ACC in enterprises here as well as impacts of each CG characteristics on this principle implementation Thesis’s theoretical and practical contributions would be useful references for enterprises, investors, authorities and researchers in their analysis into quality of financial statement and evaluation on CG in order to supply adjustments for better CG, which helps to improve usefulness and reliability of information disclosed by enterprises
