1. Introduction The rate of non-financial information disclosure is growing in a staggering rate, for over the
last decade, corporate responsibility reporting has become a common practice for the biggest
companies in the world (non-financial information reporting, corporate social responsibility
reporting and sustainability reporting means providing information in terms of economic,
environmental, social and governance performance. In this paper, these terms are used
interchangeably).
According to the survey conducted by KPMG (2015), 64% of the G250 (top 250 of Fortune
500) companies published corporate responsibility reports in 2005, while the rate of corporate
responsibility reporting has reached 92% in 2015.
As corporate responsibility reporting continues to grow in importance, the demand for
external assurance on non-financial information also increased dramatically. Third-party
assurance of corporate responsibility information has been established as a standard practice
for large multinational corporations in the world. More specifically, only 30% of the G250
firms have their non-financial information independently assured in 2005, but the percentage
has increased to 63% in 2015 (KPMG 2015).
Although assurance on sustainability reports has become so important, few people really
understand what “assurance quality” means in terms of non-financial information, and
research in non-financial information assurance quality is relatively sparse. Unlike financial
information assurance, auditing professions do not have a monopoly position on non-
financial information assurance, even though major accountancy organizations currently
dominates the market, the competition with other professions will be fierce in the future.
Therefore, it is important for practitioners and researchers to understand what non-financial
information assurance quality really means. It is also very important to know how the
emergence of greenhouse gas (GHG) reporting and internet-based non-financial disclosure
will affect the auditing profession.
The paper proceeds as follows. The next section provides a brief summary of some of the
literature that deals with non-financial information assurance quality. The relevant auditing
standards for non-financial disclosures are subsequently analyzed and compared. The
following section discusses GHG emissions disclosures: the reporting regulations and
1
schemes for GHG emissions, the assurance providers and standards used for this disclosure
and most importantly, the reason for the need of independent assurance standards for GHG
emissions disclosures. This is succeeded by discussion of the emergence of internet-based
non-financial disclosure, and how it may affect auditing profession. The final part
concludes.
2. Key points of assurance quality literature
• A brief summary Previous research has pointed out the problem in the assurance of non-financial disclosures,
managerial capture. The content analysis conducted by Ball et al. (2000), O’Dwyer (2003),
O’Dwyer and Owen (2005, 2007) and Manurung and Basuki (2010) indicates that managerial
capture is prevailed in the assurance process. For instance, Hasan et al. (2003) find managers
take control of the assurance process by frequently nominating themselves as addressees of
assurance statements.
As for the assurance providers for non-financial disclosures, FEE (2002) identifies five major
assurance providers for non-financial disclosures including experts, rating agents,
accountants/auditors, consultants and social auditors. Considerable differences exist in
presentation formats and contents (Deegan et al 2006), the level of assurance (Mock et al
2007) and quality of assurance (Perego and Kolk, 2012). Thus, choice of assurance providers
should have a significant influence on the overall assurance quality of non-financial
disclosures. Simnett et al (2009) find that a positive relationship exists between company size
and the choice of the auditor. Different assurance providers’ work is perceived to have
different quality. Owen and O’Dwyer (2004) finds the difference between professional and
specialist auditors’ assurance approach results form their different conception of
accountability. Both Pflugrath (2011) and Fernandez-Feijoo et al. (2012) agree that
professional auditors provide higher quality assurance statements. Among professional
auditors, Big Four auditors are perceived to provide even higher quality assurance services
(Hasan et al. 2005; Perego 2009). Different countries have different preferences for the two
types of assurance providers. Deegan et al. (2006) find that European countries except the
UK tend to choose professional auditor as assurers. The professional auditors also dominate
1
assurance engagement for non-financial disclosures in Spanish (Sierra et al. 2013; Zorio et al.
2013). In contrast, Australia and the UK prefer to have CSR reports audited by specialist
auditors (Deegan et al., 2006; Perego, 2009; Moroney, et al. 2011). To increase the assurance
quality, Dando and Swift (2003) argue that stakeholders’ concerns should be included in CSR
auditing process. As Bebbington et al. (2007) state, materiality and relevance of information
presented in the assurance statements can be improved with more stakeholder involvement in
assurance engagement.
• Content analysis
Assurance quality is a complex concept. In the context of non-financial information, it is even
harder to define. Although we did not find a generally accepted definition of assurance
quality in terms of non-financial information, we found that many researchers attempted to
measure assurance quality quantitatively, and the most popular approach was content analysis
of assurance statements.
In order to assess assurance quality on sustainability reports, O’Dwyer and Owen (2005)
constructed an index based on recommended minimum contents of three standards –
AA1000AS, FEE and GRI. Perego and Kolk (2012) and Segui-Mas, Bollas-Araya and Polo-
Garrido (2015) used almost the same sets of index, but they also assign a number to each item
in the index, so that the assurance quality can be measured numerically. For example, if the
finishing date of an assurance exercise is mentioned, one score will be awarded to that
assurance statement (Perego & Kolk 2012). Zorio, Benau and Sierra (2012) developed an
index which was also based on content analysis of assurance statements, but the contents
were based on ISAE 3000 and AA1000AS. Sethi, Martell and Demir 2015 (2015) analyzed
assurance quality based on a structural framework called the CSR-S Monitor, which utilized
content analysis approach as well. The CSR-S Monitor divides the content of sustainability
reports into 11 quantifiable elements, which is very similar to Perego and Kolk’s (2012)
method. The most frequently used items that are included in the assurance quality index are
listed in Table 1.

Completeness Indicating if the report satisfies the AA1000 principle of "completeness"
Responsiveness Indicating if the report satisfies the AA1000 principle of "responsiveness"
Conclusion A statement expressing the result of the assurance exercise
In most of the studies mentioned above, researchers did not explain why they chose the index
to measure assurance quality, nor did they evaluate whether the index was a good proxy of
assurance quality. In many cases, researchers focused on the question “what factors may
affect assurance quality” without discussing the meaning of assurance quality. For example,
Perego and Kolk (2012) found accounting firms provided assurance service with higher
quality, because the assurance statements produced by accountants received higher scores
than specialists and certificate bodies. However, they only mentioned that the quality of
1
assurance statement was based on O’Dwyer and Owen’s (2005) work, without evaluating if it
was appropriate to measure assurance quality.
• The problem of not addressing assurance statement to external stakeholders
Sustainability reports are aimed to provide useful information to a wide range of
stakeholders, however, assurance providers are reluctant to address assurance statements to
external stakeholders. In financial information reporting, there is a requirement that the audit
report must be addressed to shareholders, but in terms of non-financial information reporting,
specifying an addressee is not required. In most of the sustainability reporting assurance
statements, no addressee is identified (Deegan, Cooper & Shelly 2006). On the few occasions
that an addressee is identified, it is usually management of the reporting companies (Owen &
O’Dwyer 2004).
The reluctance to address assurance statements to external stakeholders may imply that the
assurance providers are ultimately accountable to management of the reporting entities
(O’Dwyer & Owen 2005), thus auditors who provide assurance service on non-financial
information may not be truly independent. Reporting in financial information is heavily
regulated, however, all aspects in non-financial information reporting are controlled by the
reporting organization (Sethi, Martell & Demir 2015). Therefore, there might be a significant
degree of management control over reporting and assurance process (Owen & O’Dwyer
2004). If assurance providers are only responsible to the management, they will potentially
avoid auditing information that may damage the reputation of the reporting organization.
Due to auditors’ lack of independence, the assurance quality on non-financial information
will not be high.
Not addressing stakeholders as main users of assurance statements also has implications on
materiality of the information provided (Owen & O’Dwyer 2005). According to AA1000AS
(AccountAbility 2008), a piece of information is deemed material if its omission or
misstatement will affect stakeholders’ decision making. Without considering stakeholders’
information needs, materiality cannot be defined properly, and thus the assurance quality will
be negatively affected. In order to enhance assurance quality in sustainability reporting,
stakeholders must be involved in the assurance process, and they should be identified clearly
in the assurance statement as key users.

• Audit quality indicators In financial information assurance, many different audit quality indicators have been
developed, which help people to gain insight into financial statement audit quality. For
example, PCAOB uses audit quality indicators such as “training hours per audit
professional”, “average compensation to ensure adequate financial incentive” and “frequency
of financial statement restatement for errors” (PCAOB 2013).
However, in the context of non-financial information assurance, no such assurance indicator
has been developed. Cohen (2014) pointed out that some of the financial information
assurance quality indicators are also appropriate to non-financial information auditing, while
others are not very relevant. The extent to which the indicators are relevant to non-financial
information assurance is shown in table 2 (Cohen 2014). It is an interesting question for
researchers to investigate further in the future.

3. Standards for assurance of non-financial disclosures
1
In response to the growing demand for non-financial information reporting, many assurance
frameworks have been developed. Among them, two standards are particularly important: the
AA1000 Assurance Standard (AA1000AS) issued by AccountAbility, and IAASB’s
ISAE3000- Assurance Engagements Other Than Audits or Reviews of Historical Financial
Information.
Although both AA1000AS and ISAE 3000 can be used to provide sustainability assurance,
they are very different from each other. Generally speaking, ISAE 3000 provides more
specific guidance and more rigorous procedures, ensuring that the assurance engagement will
be undertaken in accordance with professional auditing standards. In contrast, AA1000AS
chooses a more open-ended approach, and focuses on meeting stakeholders’ needs (Iansen-
Rogers & Oelschlaegel 2005). The major differences between ISAE 300 and AA100AS are
illustrated in Table 3.

ISAE 300 and AA100AS are complementary and research shows that a large proportion of
assurance engagements use both ISAE 300 and AA100AS at the same time.
As to assurance standards for carbon emissions disclosures, there are two internationally
recognized standards ISO 14064-3:2006 Specification with Guidance for the Validation and
Verification of Greenhouse Gas Assertions, and ISAE 3410 Assurance on greenhouse Gas
Statements. ISO 14064-3:2006 provides, for the first time, a standardized process for
conducting a verification of a GHG inventory. It establishes four principles for conducting
GHG verification: independence, ethical conduct, fair presentation, and due professional care.
This standard also establishes the “fundamentals” for the verification, including the
verification level of assurance, objectives, criteria, scope, and definition of materiality under
the verification (Wintergreen and Delaney, 2007).
Compared to ISO 14064-3: 2006, ISAE 3410 is a relatively new assurance standard for
carbon emissions disclosures. It was released in 2012 by IAASB to enhance the quality and
consistency of assurance engagements on GHG emissions disclosures. The objective of an
engagement under ISAE 3410 is to obtain either limited or reasonable assurance, as
applicable, about whether the GHG statement is free from material misstatement, whether
due to fraud or error. An ISAE 3410 engagement adopts a risk-based approach, regardless of
whether it is a reasonable or limited assurance engagement. This standard applies to
assurance procedures performed with respect to the GHG statement other than when the
GHG statement is a relatively minor part of the overall information subject to assurance
(Ifac.org, 2016).
Huggins et al (2011) points out that the materiality level for different types of assurance and
the amount of detail about the assurance plan revealed to the client are the main differences
between the two standards. ISO 14064-3 states the agreed level of assurance decides the
materiality level while ISAE 3410 states that the materiality level is the same in both limited
and reasonable level of assurance. ISO 14064-3 states that the client needs to know how the
10
assurer will conduct the assurance engagement, while ISAE 3410 states that the assurer must
not discuss the details of the assurance procedures with the client. Different assurance
providers tend to use different assurance standards to conduct the assurance of GHG
emissions disclosures. Audit and assurance services firm providers use the ISAE 3410 more
often while the ISO 1404-3 is the commonly used by specialist auditors.
4. Assurance for GHG emissions disclosures As the global climate warming is drawing more attention worldwide, there has been research
on the specific issue of assurance of GHG emissions disclosures. Simnett and Nugent (2007)
and Simnett et al (2009a) point out that a specific assurance standard for GHG emission
disclosures is necessary as the world is paying more attention to the economic and
environmental impacts of global climate warming and a specific assurance standards can
increase the credibility of this disclosure and any associated trading scheme. Huggins et al.
(2011) suggests that GHG emissions disclosures be included in the financial statements of the
annual report. Green and Li (2011) finds that an expectation gap exists between emissions
preparers, emissions assurers and shareholders in relation to relative responsibilities of
assurers and management, as well as in relation to the assurers’ objectivity. By examining the
assurance practices of 3008 companies across 43 countries between 2006 and 2008, Green
and Zhou (2013) finds that the assurance services for carbon emissions disclosures were
demanded mainly in Europe and companies from carbon intensive industries.
The demand for the disclosure of GHG emissions has increased because of mandatory
Emissions Trading Schemes (ETSs) and Emissions Reporting Schemes (ERSs) in some
countries, including the European Union Emissions Trading Scheme, the United States
Environmental Protection Agency’s Mandatory Greenhouse Gas Reporting Program,
California’s Regulation for the Mandatory Reporting of Greenhouse Gas Emissions,
Alberta’s Climate Change and Emissions Management Act, Australia’s National Greenhouse
and Energy Reporting Scheme, and the New Zealand Emissions Trading Scheme (Green and
Zhou, 2013). There has also been an increase in voluntary reporting of GHG emissions from
entities participating in voluntary ETTs and reporting schemes. Organizations voluntarily
disclose GHG emissions to show that they are good corporate citizens. That can send a signal
to their customers that they are moving towards carbon neutrality and helps differentiate them
11
from their competitors. The assurance of GHG emissions disclosures is largely voluntary
even for entities covered in mandatory ETSs. Only Alberta’s Climate Change and Emissions
Management Act in Canada requires GHG reporting to have a limited level of assurance.
Before 2006, there was no specific assurance standard for GHG emissions disclosures. Just
like other non-financial information, GHG emissions disclosures were audited using AA
1000 Assurance Standard or ISAE 3000 Assurance Engagements Other than Audits or
Reviews of Historical Financial Information.
4.1 the need for independent assurance standards for GHG emissions.
Simnett and Nugent (2007) points out that a specific assurance standard for GHG emission
disclosures is necessary as the economic and environmental impacts of global climate
warming is drawing more attention and a specific assurance standard can increase the
credibility of this disclosure and any associated trading scheme. In fact, the regulatory
requirements in each country that aim to control global warming are the driving force for the
specific assurance standards for GHG emissions. For example, entities covered in Australia’s
National Greenhouse and Energy Reporting (NGER) Act of 2007 will face potential fines
reaching six figures for non-compliance in their GHG emissions reporting. Therefore the
credibility of the GHG emissions disclosures becomes very important. Besides, as the
emission trading schemes are introduced in more countries, the credibility of GHG emissions
disclosures become more significant because organizations can buy or sell carbon permits,
which is based on whether they have exceeded or fallen below their permitted emissions
level. But before 2012, there was no specific assurance standards for GHG emissions
disclosures developed by the international accounting bodies. Therefore this type of
disclosure was audited using the same assurance standards as other non-financial information
and usually only a limited assurance level was provided for GHG emissions disclosures. But
unlike other non-financial information, the GHG emissions include three types and each
requires different auditing procedures and not all three can have the same level of assurance.
Because of the unique nature of GHG emissions disclosure and the importance stakeholders
place on its credibility, an independent assurance standard for GHG carbon disclosures is
necessary.
4.2 the assurance provider
12
Green and Zhou (2013) identify two broad types of assurance providers, audit and assurance
services firm providers and specialist providers. There are differences in the assurance
practices between the two types of assurance providers, including: the scope of the assurance,
the type of report conveying the assurance, the level of the assurance as well as the standards
used for the assurance. When the subject matter is the whole sustainability report, the
assurance service for the GHG emissions disclosures is mainly provided by audit and
assurance services firms. Companies appear to be more willing to choose the assurance
services from specialist providers if the subject assured is GHG only. There are two
internationally recognized assurance standards for carbon emissions disclosures, ISO 14064-
3:2006 Specification with Guidance for the Validation and Verification of Greenhouse Gas
Assertions, and ISAE 3410 Assurance on greenhouse Gas Statements.
4.3 Future development for the assurance of GHG emissions. To increase the level of assurance provided for carbon emissions disclosures, some
researchers suggest that this type of information be included in the financial statements of the
annual report. This can ensure that “these disclosures be subject to the same rigorous level of
assurance as other aspects of the financial report” (Simnett et al. 2007; Huggins et al. 2011).
In fact there are two developments occurring that will make this suggestion possible. One
trend is the integrated reporting, which aims to combine non-financial information with
financial information. The other is the emissions trading schemes. When these schemes issue
tradable securities that will have the characteristics of assets or liabilities, these securities will
need to be included in financial statements (Huggins et al. 2011).
5 Assurance of non-financial disclosure on website
Using internet as a channel to disseminate non-financial information has become a common
practice for many companies in recent years, because it is widely believed that internet-based
reporting has many advantages. However, disclosing information on websites also presents
new challenges to auditors. Online reporting will potentially widen the expectation gap
between auditors and users, and increases auditing risk. Since internet based non-financial
information reporting will grow in importance in the future, it is important for practitioners
and researchers understand the implications of internet-based reporting.
13
5.1 Advantages of internet-based non-financial information disclosure (1) Lower information costs:
Disclosing non-financial information on internet will reduce information costs (Herzig &
Godemann 2010). For example, storing information on a company’s website saves printing
and dissemination costs. In addition, by utilizing XBRL (extensible Business Reporting
Language), a piece of information that is used in multiple ways only need to be prepared for
once, thus avoiding the cost of transferring the information into different formats
(Wagenhofer 2003). Moreover, users of the non-financial information can access specific
information more easily. Sustainability reports usually has a very broad scope, and users have
heterogeneous information demands. If the sustainability report is only provided in printed
format, it will be difficult for users to find the specific information they want. Fortunately,
internet-based reporting provides search engines and hyperlinks, which help users to locate
the information they need (Herzig & Godemann, 2010).
(2) Larger amount of relevant information: At the beginning stage of internet-based reporting, information disclosed on internet is
identical to the printed version, usually in HTML and PDF format. However, in recent years,
it is believed larger amount of information should be incorporated in digital format than in
the printed version (Lymer & Debreceny 2003). First, a printed sustainability report has finite
number of pages, so it only contains limited amount of information. However, all relevant
information can be disclosed on internet. Second, publishing and disseminating printed report
is time consuming, thus some information in the hardcopy is outdated. In contrast, new
information can be updated immediately on a company’s website. As a result, internet-based
sustainability reporting provides users a more complete vision of a company’s sustainability
performance (Herzig & Godemann, 2010).
(3) Customized information: Information needs of different stakeholders are heterogeneous, therefore it would be better
for sustainability report preparers to identify some critical stakeholder groups, and provide
them with relevant and customized information. However, the traditional printed
sustainability report is designed to meet all stakeholders’ needs, thus the information
14
provided may be too general to meet any stakeholder’s real needs (Isenmann 2004). Internet-
based technology will enable organizations to provide more customised information to
important stakeholders. For example, information preparers can develop a so-called XML
schema, and each XML schema can be used to produce customised information for a target
stakeholder group (Isenmann, Bey and Welter 2007).
(4) More interaction with stakeholders: Stakeholder involvement is very important for sustainability reporting. In order to decide
what information is relevant and material, companies must communicate to stakeholders.
AA1000AS emphasizes that an organization must be responsive to stakeholders’ concerns.
To prepare printed report, organizations usually only contact stakeholders before the
production of report. By disclosing information on internet, companies are able to contact
stakeholders continuously. Stakeholders can contact the company in various ways, for
example by email, on internet chat room or through video conference. It will help companies
to better understand stakeholders’ needs, and provide information with more relevance and
higher quality (Herzig & Godemann 2010).
5.2 Challenges to auditors (1) Professional pronouncement:
The emergence of internet-based reporting presents new challenges to auditors. Currently, it
is still unclear whether auditors have responsibilities to examine information provided on
corporate websites. The existing standards and guidance on internet reporting assurance are
sometimes ambiguous, and standards in different countries are very different from each other.
According to International Standard on Auditing (ISA) 720: The Auditor’s Responsibilities
Relating to Other Information which is issued by International Federation of Accountants
(IFAC), auditors are responsible to make sure that there is no material inconsistency between
audited information and “other information”. However, ISA 720 excludes information
disclosed on websites from the definition of “other information”. Although IAASB
considered if ISA 720 should include internet-reporting issues, they eventually concluded that
it was impractical for auditors to monitor online information continuously (Fisher & Naylor
2015).
15
In the US, according to Statement of Auditing Standards No.8 “Other Information in
Documents Containing Audited Financial Statements”, auditors have no responsibilities to
read information on their client’s websites, nor do they need to consider consistency between
audited information and online information (Fisher & Naylor 2015).
In contrast to the US standard, Australian standard (Auditing Guidance Statement 1050)
suggests that auditors do have responsibilities in examining electronic data on the internet.
However, AGS 1050 does not provide specific guidance on how to conduct assurance
engagements on information presented on corporate websites. The guidance suggests that
auditors should use their professional judgement to determine what information disclosed on
the internet should be examined (Lymer & Debreceny 2003). Interestingly, AGS 1050
suggests that “Engagements to provide assurance in respect of matters relating to the entity’s
web site do not form part of the financial report auditing engagement, but may be agreed with
management as a separate engagement” (AUASB 2002, AGS 1050, para. 20), because
Australian standard setters believe that the current audit report is not suitable to internet-
based reporting (Lymer & Debreceny 2003).
(2) Inappropriate association of audited and non-audited information: When a company disclose information on its websites, unaudited information is sometimes
presented alongside audited information. Moreover, hyperlinks connect audited information
to web pages which contains unaudited information. As a result, it is difficult for users to
distinguish between audited and non-audited information (Fisher & Naylor 2015). Hodge
(2001) finds if a company connect audited financial report with unaudited information by
hyperlinks, users are highly likely to perceive the unaudited information as audited.
Therefore, firms can potentially manipulate users’ perception by using hyperlinks. In order to
protect their reputation, it is important for auditors to make sure that their clients have made
adequate steps to prevent inappropriate association of audited and non-audited information
(Fisher, Oyelere & Laswad 2004).
The most commonly used method to distinguish audited information from unaudited
information is to making audited report into PDF files, while keeping unaudited information
in other formats. Since many users are not sophisticated enough, complicated hyperlinks can
still confuse them. Auditors should ask their clients to make audited information which is
presented on internet more visually distinctive, for example using watermarks or intermediate
warning web pages (Fisher, Oyelere & Laswad 2004).
16
(3) Omission of audit report: A large proportion of companies publish their financial reports on the internet do not include
the corresponding audit reports (Fisher, Oyelere & Laswad 2004). Ettredge (2000) finds that
compare to companies receive unqualified audit opinions, companies receive qualified
opinions or going concern modifications are more likely to omit the auditors’ reports on
websites. Therefore, users cannot decide if the information on internet has been audited, and
they cannot see the auditor’s opinions. In terms of non-financial reporting, although external
assurance is not mandatory, it is still important for auditors to make sure that their clients
who report on the internet also include the assurance report on their websites.
(4) Continuous monitoring: To provide users more timely information, companies often release real-time information on
their websites. To make sure that all material information updated is true and fair, auditors
will have to monitor the information published on websites continuously. Furthermore, online
information is susceptible to unauthorized alteration, for example corporate websites may be
attacked by hackers. Many people believe it is auditors’ responsibility to protect the integrity
of the information disclosed online, they suggest that all material modification of information
on the internet must be authorized by auditors (Khadaroo 2005).
(5) Expectation gap: Since corporate websites have become a major source of information, many users will expect
auditors to protect the integrity of information provided online. However, auditors are slow to
adapt the internet reporting environment. As can be seen, the emergence of internet-based
reporting makes auditors’ work more difficult, but professional pronouncement and auditing
standards do not provide auditors clear guidance on how to examine information presented on
corporate websites. Therefore, the audit expectation gap will become wider.
Fisher and Naylor (2015) conducted a survey in New Zealand, and concluded that the
expectation gap of auditors’ responsibilities in internet reporting related issues does exist.
More specifically, auditors in New Zealand were unsure (or did not want to acknowledge)
their internet reporting related responsibilities, while shareholders and sophisticated
information users could identify many auditor’s existing responsibilities. In order to reduce
auditors’ expectation gap, Fisher and Naylor (2015) suggested the overall expectation gap
should be decomposed into different parts, and each part should be managed differently.
17
According to Porter (1993), audit expectation gap can be divided into three parts: deficient
standard gap, deficient performance gap, and reasonableness gap.
Reasonableness gap - the gap between society’s expectation and what auditors can
reasonably be expected. Some of the users’ expectations are unrealistic, for example many
shareholders thought auditors should monitor the change in information on websites
continuously to protect the integrity of online information. However, continuous monitoring
online information is too costly and impractical. Therefore, auditors should educate the users
so that their expectations will not be unrealistic (Fisher & Naylor 2015).
Deficient standard gap - the gap between society’s reasonable expectation and auditor’s
existing legal responsibilities. Although in New Zealand, the assurance standard does not
require auditors to check if there is any inappropriate omission of auditor’s report on the
internet, according to the survey, both auditors and users believed that auditors should accept
this responsibility. Obviously, it helps users to better understand whether information
disclosed on a website has been audited, while the incremental cost for auditors is minimal.
Assurance standard should specify more auditors’ responsibilities in internet reporting issues
if they pass the cost-benefit test (Fisher & Naylor 2015).
Deficient performance gap - the gap between auditor’s existing legal responsibilities and
auditors’ performance perceived by society. It reflects how well auditors have performed
their existing internet reporting related responsibilities. For example, in New Zealand
auditors are responsible to make sure that there is no material inconsistency between audited
information and information disclosed on companies’ websites. However, most users thought
auditors did not do very well in this job. To reduce expectation gap, auditors should improve
their performance (Fisher & Naylor 2015).
5.3 Future of the internet-based non-financial information assurance In my opinion, internet based non-financial information assurance service has three main
trends. First, as the internet based reporting continue to grow in importance, new assurance
standards and approaches need to be developed, so that auditors can better adapt online
reporting environment. Second, rather than verifying the accuracy of data, auditors should put
more efforts in reviewing the overall information system. Third, integrated reporting which
combines financial and non-financial information in a single report might become important
18
in the future, so researchers and practitioners should start to consider how to conduct
assurance engagements in relation to integrated reporting.
(1) New auditing approaches: As far as I am concerned, some traditional auditing approaches might not be appropriate for
internet-based non-financial information reporting, so auditors and regulators should develop
new standards and techniques to better assure information disclosed electronically.
The Australian auditing standard AGS 105 suggests disclosing information on the internet
may require auditors to consider new approaches, and it points out that some factors may
affect the electronic presentation of the audit report. First, in printed format, audit report links
the financial report which has been audited by reference to page numbers. However, page
numbers are not suitable in digital format (AUASB 2002, AGS 1050, para. 25). I think the
audit report can also be made into digital format, so that the audit report and relevant sections
of financial report can be connected by hyperlinks. Second, auditor’s signature traditionally
provides authentic identification of the auditor, but on the internet, signatures may not be able
to protected information from unauthorized changes (AUASB 2002, AGS 1050, para. 25). It
is suggested that auditors should apply cryptographic techniques and digital signatures on the
internet (Fisher, Oyelere & Laswad 2004). Furthermore, the content of audit report can also
be changed in order to decrease audit risk. For example, auditors can indicate in the audit
report that they have not provide assurance on information disclosed on their client’s website,
or they do not provide any opinion on information that is hyperlinked (Fisher, Oyelere &
Laswad 2004). In addition, some people suggest better control will be achieved if auditors
host the website which contains audited information for their clients (Khadaroo 2005).
It is important to develop assurance standards which provide clear guidance on how to audit
non-financial information disclosed on the internet. Currently, there is a lack of generally
accepted assurance guidance on internet reporting and sustainability reporting. However, as
more and more companies start to disclose non-financial information on the internet, auditors
will need more specific guidance to meet this demand. Unlike financial reporting, auditing
profession does not have a monopoly position in sustainability reporting. If auditors do not
respond quickly to the internet reporting environment, they will be placed at a competitive
disadvantage relative to other professions (Xiao, Jones & Lymer 2002).
19
(2) WebTrust and SysTrust: Due to the innovation of internet technology, verifying the accuracy of particular information
will become less practical and less important. Internet-based reporting enables more
information to be produced and disseminated in a lower cost on a continuous basis.
Therefore, asking auditors to assume an ongoing responsibility to monitor such a large
amount of information is unrealistic. More importantly, the format of internet reporting is too
flexible and customised. For example, XBRL allows users to define the structure of the
online reports, and put their own assumptions to produce the information they want
(Wagenhofer 2003). As a result, it will be impossible to examine all customised reports.
In the future, the service on auditing the overall soundness of the information system will
become more important, therefore trust services such as WebTrust and SysTrust will be more
popular. In a SysTrust engagement, auditors evaluate the reliability of a company’s
information system, and test if the system can operate efficiently without material error.
SysTrust increases the credibility of information presented on a website, and reduces the
likelihood of business interruptions due to system breakdown (Bedard, Jackson & Graham
2005). By comparison, WebTrust is more focused on E-commerce. If an internet vendor
discloses and follows its business practices, completes and bills transaction as agreed, and
protects clients’ privacy, a WebTrust seal will be provided on the vendor’s website, thereby
increasing his trustworthiness (Houston & Taylor 1999).
(3) Integrating financial and non-financial information: Some researchers believe that stand-alone environmental, social and financial reports should
be integrated into one report which shows interrelations between financial and non-financial
information (Eccles & Krzus 2010). Since an organisation’s economic and social
performance may affect its long-term profitability, showing the relationship between
economic and non-economic factors will better inform investors and other stakeholders how
an organization creates value in a sustainable manner (Eccles, Schulschenk & Serafeim
2011). The relationship between environmental, social and financial performance can be
more clearly illustrated in an internet-reporting environment, because internet provides
hyperlinks between different parts of the report, and connects non-financial information to
financial factors it affects (Isenmann 2004). For example, in integrated online report, users
will more easily understand how waste reduction affects productivity and future income of a
manufacturer.
20
Assurance of integrated reports is not mandatory, but assurance service does increase
credibility of the information in integrated reports. Currently, there is a lack of assurance
guidance or standard for auditing integrated reports (Cohen & Simnett 2015). Since internet
facilitates integrated reporting, many companies will present both financial and non-financial
information online in the future, and guidance for integrated reporting should be developed in
the future.
6. Conclusion In this report, we first find that in the context of non-financial information, currently there is
no generally accepted definition of assurance quality. The most commonly used method to
measure assurance quality by researchers is content analysis of assurance statement. Second,
we discuss the implication of greenhouse gas emissions disclosures. Third, although internet
based non-financial information reporting has many advantages, it also presents many
challenges.
