ABSTRACT
This research ascertains  the structure, composition, and extent of the Audit Expectation Gap (AEG) in  Vietnam, thereby demonstrating the existence of the AEG in Vietnam. This study  indicates reasonable solutions in narrowing the AEG in auditing financial  report in Vietnam. The research design used the research framework of Porter (1993); Porter and Gowthrope (2004
); Porter et al. (2012
) and Turner et al. (2010
). Survey data was collected by sending a random  survey questionnaire to four interest groups: (i) auditors (the sample of auditors  was a random selection from the list membership of the Vietnam Association of  Certified Public Accountants (VACPA), (ii) auditees (joint-stock companies  listed on the securities market), (iii) audit beneficiaries - in the financial  community (direct beneficiaries of the audit function as users of audited  financial statements), and (iv) audit beneficiaries - general public (they are  randomly selected in Ho Chi Minh City, Hanoi (Capital of Vietnam) and  neighboring provinces where many businesses, investors, and universities are  located). The total number of questionnaires sent out was 1400. The number of  usable responses was 454 or 32%. The study results provided empirical evidence  that the existing AEG in Vietnam was significantly in line with the definition  of audit expectation-performance gap (AEG) of Porter (1993
) and that there was no research component  proposed by Turner et al. (2010
). The structure and extent of the AEG in  Vietnam: reasonableness gap 31%, deficient standards gap 49%, and deficient  performance gap 20%. In this study, the response rates of the survey groups  were low. Practical implications included:  identifying responsibilities which constitute  each component of the AEG in Vietnam and determining the specific causes  relevant to each responsibility and solutions to adjust, supplement or amend  promptly. This would narrow the AEG in Vietnam. The AEG’s component’s measurements  provide the indicator for the relevant agencies to build, implement policies to  improve the capacity of independent auditing profession in Vietnam.

Contribution/ Originality: This study contributes to understanding the structure, composition, and extent of the Audit Expectation Gap (AEG) in Vietnam, thereby demonstrating the existence of the AEG in Vietnam. This study indicates some reasonable solutions in narrowing the audit expectation gap in Vietnam.
“Expectation gap” is the term that was used for the first time in Liggio (1974) and was defined as the difference in opinion between the public and the  auditor regarding audit responsibility. Cohen Commission extended the definition to as “whether a  gap may exist between what the public expects or needs and what auditors can  and should reasonably expect to accomplish” (Cohen, 1978
) and was understood in a  general way as “The difference between what the  public expects from the audit profession and what the audit profession really  can provide" (Jennings et al., 1993
). Initially, most studies have  shown that the AEG only includes the expected distance components expected by  the public to be unreasonable in the audit profession (Lee 1970, Beck 1973, Baron et al. 1977
). Accordingly, the main reason  for the AEG’s existence is not the responsibility of the auditors but the lack  of understanding of the public (Lee 1970, Humphrey et al. 1993, McEnroe & Martens 2001, Lee &  Azham 2008). This implies that errors are due to the public and the AEG exists  objectively due to differences in opinion between the auditors and the groups  using the financial statements. There are different levels of interest and  knowledge about audit in each group using financial statements (McEnroe & Martens, 2001). Conclusions drawn from empirical  studies in most countries around the world in this period support the idea that  the AEG always exists objectively with the audit profession and they cannot  narrow down entirely if due to differences of opinion. Economic, political and  social factors do not directly affect the emergence and existence of the AEG (Lee 1970, Beck 1972, Humphrey et al. 1993). More than a decade later, the  AEG is still in existence and tends to widen. The increasing criticism of the  audit profession requires researchers and professionals to take a new research  approach toward the AEG and reconsider whether the impact of the AEG has  negatively impacted the position of the audit profession in the society. Porter (1993
) proposed that the AEG should  be extended to AEG. Porter (1993
) argument was that recent  criticism against auditors has arisen from the fact that auditing professions  fail to meet social expectations. That result has undermined confidence in the  audit function as well as its position in social structure. 
 According to Limperg (1933) the position and role of an  audit are based on the level of trust formed on the basis of the interaction  between public expectations and perception. The bigger the AEG, the more likely  the audit profession does not meet the expectations of the society. As a  consequence, the public's trust in the audit profession is declining, so  auditing can be removed. Therefore, in order to narrow the AEG, according to Porter (1993
) it is necessary to identify  (i) the audit responsibility that society expects; (ii) the reasonable  responsibility that society expects; and (iii) the extent to which the auditor  meets the reasonable expectations of the society. 
 Narrowing the  AEG is particularly effective when measuring  the level of each component of the gap and pointing out which group is responsible for a particular case. So, in the early  1990s, Porter (1993) proposed the definition of the  AEG, which differs in structure and composition from previous definitions, in  order to determine whether the AEG exists as a liability of public or auditors.  Subsequently, Porter et al. (2012
) and Porter and  Gowthrope (2004
) conducted a survey to measure  and assess the degree of each component of the gap defined in 1993 in New Zealand and  England. The study compared the changes, modifies and evaluates the  effectiveness of the AEG reduction solutions in practice. In Vietnam, the AEG  is a new term for professionals and regulatory organizations, even in the field  of research. 
The Ministry of Finance has amended and issued the Vietnamese Standards on Auditing effective from January 1st, 2014 which adhere to the International Standards on Auditing. The process of developing the Vietnamese Standards on Auditing has been consulted on by experts and researchers but has not yet been based on specific social survey results on the position and role of the audit profession, public expectations, and expectations for auditor’s responsibilities. Therefore, although there have been more than three years of application, no empirical studies have evaluated the impact and benefits of the Vietnamese Standards on Auditing.
In Vietnam, no research has ever identified and measured the extent to which each component constitutes the AEG. Therefore, this study was conducted with two main objectives:
 The AEG has been defined and proposed  by many different researchers and professionals. Liggio (1974) defines the AEG as the  difference between the levels of expected performance “as envisioned by the  independent accountant and by the user of financial statements” (p.27). In  1978, the Cohen Commission extended the definition of the AEG from “users of  financial statements” to “the public”, and from “expected performance” to “what  auditors can and should reasonably expect to accomplish”. Also focusing on  auditors’ responsibility, but more specifically, Guy and Sullivan  (1988
) states that  "the AEG is the difference between what the public believes to be within  the responsibilities of the auditors and what auditors themselves believe to be  within their responsibilities. The limitation of this definition is that it  only considers the liability of the auditor from auditors and audit firms’  perspectives. The perspective of the auditor and audit firm can be governed by  the regulations, work environment, size of the company, and reputation of the audit firm.
 Porter (1993) based on the results of a  study conducted in 1989 in  New Zealand, commented that the definition of Liggio (1974
) and Cohen (1978
) were too narrow and did not  mention that the auditor may not accomplish “expected performance” (Liggio, 1974
) or what they can and  reasonably should” (Cohen, 1978
). It is impossible to assess  the situation in which an auditor fails to complete his/her work or what an  auditor is capable of performing. 
 Therefore, in order to recognize the  AEG, it is necessary to identify (i) the audit  responsibilities which the auditor is expected to perform by the society; (ii)  the reasonable audit responsibilities which the auditor is expected to perform  by the society; and (iii) auditors’ ability to  meet the social expectations (Porter et al., 2005). Thus, Porter asserted that  the  AEG study must be designed to allow  the extension of different approaches and explanations.  Porter proposed adding a “performance gap” and defined AEG as the gap between  society’s expectation of auditors and auditors’ performance.  The AEG model, according to Porter (1993
) consists of two components: 
This component  may be subdivided into:
  (a) The “deficient  standards gap” – the gap between the auditors’ responsibilities which are  reasonably expected and those auditors are required to perform by statute or  case law, regulations or professional promulgations.
  (b) The “deficient  performance gap” – the gap between the expected standard of performance of  auditors’ existing responsibilities, and what is perceived to be delivered, by  the society.
 Turner et al. (2010) argued that Porter (1993
)  AEG model had the limitation of not indicating  that the audit profession must provide services to more than one customer, and had not addressed the issue of the exchange of information  between auditing firms and auditees. This can cause the possibility that the  user has no need for the provided auditing services or the auditees does not  want to pay for the responsibilities performed by the auditor in accordance  with the professional standards. Accordingly, alongside the components similar  to Porter (1993
) AEG model, Turner et al. (2010
) had added another component  called “the research” for when a  service firm did not have information on what customers expect. This is formed when an auditor performs  auditing tasks and responsibilities that are not requested or expected by the  public. For example, international accounting standards (ISA) require auditors  to provide comments on auditees’ compliance  with environmental regulations but developing countries such as Vietnam do not  yet have these regulations, which require enterprises to publish financial  information related to environmental activities.
Porter (1993) conducted the first survey in  New Zealand in 1989 to determine the structure, composition, and extent of the  audit expectation- performance gap. Research methods were inherited partially from studies by Lee (1970
) and Beck (1973
). This research provided a  method for determining the composition, structure, and measurement of the  distance of each component that makes up the AEG. More importantly, this  research indicated a comprehensive approach towards narrowing the gap, thereby,  reducing criticism and litigation that auditors were facing. Research results  indicated that the AEG exists between auditors, auditees, and the two audit beneficiary  groups. The reasonableness gap, deficient standards gap, and deficient  performance gap were respectively 34%, 50%, and 16%.
 Porter and  Gowthrope (2004) conducted a comparative study  in the UK and New Zealand in 1999 to (1) identify the components, structures  and levels of gap in the UK and New Zealand in 1999; (2) compare the  AEG between the two countries; (3) compare the  changes in NZ in 1989-1999 period. The participants in the survey were randomly  selected from four interest groups – auditors, auditees and two audit beneficiary  groups. The questionnaire included 51 existing auditor duties, the duties’  performance standard and the duties that auditors should perform. 
The research findings indicated the structure, composition, and extent of the AEG resemblance to the AEG model of Porter from1993. The results also showed, in 1999, the composition, structure, and extent of the audit expectation - performance gap in NZ and the UK were very similar. The reasonableness gap, deficient standards gap, deficient performance gap were 8%, 42% and 50% in the UK; and 6%, 41%, and 53% in NZ respectively.
In 1989, the reasonableness gap, deficient standards gap, deficient performance gap in New Zealand were 11%, 58%, and 31% respectively. There were significant changes in the structure, composition, and extent of the audit expectation - performance gap in New Zealand from 1989 to 1999: deficient standards gap reduced from 58% to 41%, deficient performance gap reduced from 11% to 6%, and responsibilities that were not reasonably expected from auditors lead to the reasonableness gap rising from 31% to 43 %.
 In 2008, Porter et al. (2012) conducted the same survey, but  added a number of new responsibilities that she believed were the responsibilities  of auditors. The results showed that the reasonableness gap, deficient  standards gap, and deficient performance gap were 50%, 43% and 7% respectively.  Thus, after twenty years, the reasonableness gap had not changed, but the  deficient standards gap had widened and the deficient performance gap had narrowed.  This means the quality of audits in New Zealand has improved significantly due  to a more stringent audit of the audit profession (Porter et al., 2012
).
  This research is based on Porter (1993) the AEG model and partially inherited the research methodology used in Porter et al. (2012
).
The objective of the study was to  discover the auditor’s responsibilities that contributed to each component of the  AEG, confirm the existence and measure the components that constitute the AEG  in Vietnam. 
 This thesis developed the research of Porter et al. (2012) in two ways. Firstly, by adding  the “research gap” in Turner et al. (2010
) to determine whether the AEG  in Vietnam was composed of three components: research gap (Turner et al., 2010
) reasonableness gap, and  performance gap (Porter, 1993
). Secondly, by exploring  and using the viewpoint of the auditors as a benchmark to explain why some of  the auditors' responsibilities are reasonably expected, although not stated in  the current auditing standards (the Porter et al. (2012
)) study has not yet been used  to explain).
 Quantitative research was conducted  through direct interviews and mail surveys with interest groups.
  Respondents were classified into four groups: 
The methods of non-probability  sampling with the number of the survey of 1,400 achieved 454 usable responses which were 32% (average responses per sample group were 113). The survey period was from  December 2016 to April 2017. The standards which defined each component constituting the AEG  according to the standards of the Porter et al. (2012) research was based on the  average total score & the proportions of each group’s responses. Microsoft Excel was used to analyze the descriptive statistics.
 The questionnaire design followed the Porter et al. (2012) and was adjusted to suit the  Vietnamese business environment. The questionnaire in Appendix  1 includes 45 proposed responsibilities of auditors and interviewers were  asked to choose the appropriate response to three questions: 
  1. Is the proposed responsibility an  existing responsibility of auditors?
  2. If so, how well is the  responsibility performed?
  3. Should the proposed responsibility  be a responsibility of auditors?
  For question 1 and 3, the options  ‘yes’, ‘no’, and ‘not sure’ were provided. These were coded +1, -1 and 0  respectively.
For question 2, the respondents were  asked to select from four options ‘poorly’, ‘adequately’, ‘well’, and ‘unable  to judge’. These were coded 1, 2, 3, and 0, respectively.
Criteria for the classification of auditors' responsibilities were:
Criteria for identifying the components of the AEG:

a) Identification of Auditors’ Responsibilities - the ‘Reasonableness Gap’
Table-1. Responsibilities which are reasonable/ unreasonable to expect from auditors.
Source: The result of the study.
b) Identification of the Responsibilities Reasonably Expected from Auditors that Auditing Standards Need to Encompass – the Deficient Standard Gap
The above analysis showed that 29 responsibilities satisfied the criterion to be recognized as responsibilities auditors are reasonably expected to perform. By comparing these 29 responsibilities with the auditing responsibilities set out in Vietnam's current regulations, laws and standards, there were sixteen existing auditors’ responsibilities in Vietnam as listed in Appendix 1, and thirteen audit responsibilities were not available in regulation, laws and Vietnamese Standards on Auditing (VSA). Thus, that constituted the “deficient standards gap”. Based on the opinion of the auditors, ten responsibilities auditors may be required by Vietnamese Standards on Auditing in normal conditions including responsibilities of 29, 28, 39, 31, 41, 32, 7, 19, 44, 38 -Table 1, Table 2 and Table 3. And three responsibilities auditors may be required by Vietnamese Standards on Auditing if there is a need of some reasonable means to ensure the risks that they face while performing their duties including responsibilities of 17, 35, 33- Table 1.
c) Identification of the Responsibilities that Being Perceived Sub-Standardly Performed by Auditors - the Deficient Performance Gap
This was based on the reader response theory to explain society’s judgment of auditors’ performance. The survey results showed that interest groups overall considered that standard performance of eight out of sixteen existing auditor responsibilities was satisfactory, including responsibilities of 3, 6, 40, 43, 21, 5, 25, 42 Para. I, as shown in Table 2.
This study provided evidence for the differences in evaluations of the standard of auditors’ performance of other responsibilities and the standard of auditors’ performance of the above eight responsibilities, considering them as unsatisfactory (Mean of Society group < 2.0). These responsibilities constituted the “deficient performance gap” Para II, as shown in Table 2.
d) Identification of Auditors’ Responsibilities - the Research Gap
The survey results showed that all sixteen existing responsibilities were those that the public expects auditors to perform and were reasonable. Thus, all existing responsibilities were needed according to public recognition and do not constitute a research gap as per Table 2.
a) Identifying the Components of the AEG
The responsibilities comprise each of the three components of the AEG: reasonable gap (thirteen responsibilities), deficient standards gap (thirteen responsibilities), deficient performance gap (eight responsibilities). There is no “research gap”.

b) The Extent of the AEG
The relative contribution of the deficient performance gap, deficient standards gap and reasonableness gap to the overall AEG are 20%, 49%, and 31% as per Figure 2.

Source: The result of the study.
The study results provided empirical evidence which demonstrated that there is a portion of the AEG parallel with the auditing profession. The results also provided the identification of auditors’ responsibilities which contributed to the AEG: thirteen out of 42 responsibilities constituted the reasonableness gap, thirteen out of 42 responsibilities constituted the deficient standard gap, eight out of 42 responsibilities constituted the deficient performance gap, and no responsibilities constituted the research gap as in the AEG model of Turner. The contributions of each component in the AEG were: reasonableness gap 31%, deficient standard gap 49%, and the deficient performance gap 20% as per Table 3.
The study of the AEG in the financial statements auditing in Vietnam has identified the components, structure, and level of the AEG, as well as the impact of audit professions on the existence of these expectation gaps; thereby, raising rational awareness of the auditing profession within the public. Conversely, the legislature and audit professionals can identify the specific responsibilities of auditors which need to be added or altered in order to enhance them in Vietnam. In addition, auditors can understand the quality of their works under social perspective. Various studies also indicated the existence of the AEG and recognized the difficulty of completely eliminating it.
The AEG always exists with the auditing profession. The development of auditing also shows that the bigger the AEG, the more detrimental it is to auditing profession. Therefore, it is significantly necessary to have appropriate policies to narrow the AEG.

To narrow the AEG in Vietnam, the study results indicated the need to improve auditor performance for eight responsibilities, develop standards on auditing for thirteen responsibilities, enhance education training focusing on ten responsibilities and increase the exchange of information by changing the form of audit reports for eight responsibilities as per Figure 3.
