The market penalizes fraud firms significantly
when the prospective fraud news is released to the
public (Christensen, Paik, & Williams, 2010).
Investors perceive fraudulent reporting to be more
prevalent in the economy or rely more on financial
statement information relative to other sources of
information, they place greater importance on
conducting their own fraud risk assessments. In turn,
investors who deem fraud risk assessment to matter
in investment decision making make greater use of
fraud red flags to avoid potentially fraudulent
investments (Brazel, Jones, Thayer, & Warne, 2015).
This study is a replication of the research of
Cahyo & Sulhani (2017) which indicated that the
audit committee had a negative effect on
whistleblowing system while the internal audit had no
effect on the whistleblowing system. Furthermore,
the whistleblowing system did not affect fraud
disclosure and fraud disclosure had a significant
negative effect on the market reaction. This study
intends to reexamine the variables that have been
studied by adding managerial ownership variables as
one element of the governance structure.
2 THEORETICAL FRAMEWORK
2.1 Audit Committee and Whistleblowing
System
The audit committee must have members who are
experts in the financial sector to improve the
supervision of the company. Increasing oversight of
companies has an impact on improved internal
control and reduced fraud practices (KNKG,
Pedoman Umum Good Corporate Governance
Indonesia, 2006). The Audit Committee which has
expertise in finance reduces problems in internal
control. This means that Audit Committee members
who have expertise in finance can increase the
effectiveness of internal controls (Khrisnan, 2005).
According to Lee and Fargher (2018), higher-quality
audit committee is associated with the
implementation of a stronger internal whistleblowing
system, so the first hypothesis in this study is
formulated as follows:
H
1
: The audit committee has an effect on the
whistleblowing system.
2.2 Internal Audit and Whistleblowing System
The importance of appropriate whistleblowing
policies and procedures to the effective discharge of
an organization’s corporate governance is significant.
Corporate governance is fundamental to effective risk
and control within organisations, which means that
whistleblowing policies must be at the heart of
internal auditors’ responsibilities (Cowan, 2014). In
other words, internal audit is a party that plays an
important role in implementing the whistleblowing
system (Read & Rama, 2003).
Internal audit function effectiveness influenced by
internal auditor competency (Arum, 2015). Therefore
internal audit competencies that measured by
expertise in finance will improve the implementation
of a whistleblowing system, so the second hypothesis
in this study is as follows:
H
2
: The internal audit has an effect on the
whistleblowing system.
2.3 Managerial Ownership and
Whistleblowing System
Managerial ownership can help reduce opportunistic
actions to maximize personal interests, in addition
managers will also be more careful in making
decisions that are in accordance with the interests of
the company because it is related to their interests as
owners, so that disclosure of internal control
information will be more qualified (Wardani &
Sulhani, 2017). Therefore the third hypothesis in this
study is as follows:
H
3
: The managerial ownership has an effect on the
whistleblowing system
2.4 Whistleblowing System and Fraud
Disclosure
Whistleblowing system can detect the majority of
fraud in an organization. Whistleblowing system is a
device that can be used to warn management about
fraud within the company (KNKG, Pedoman Sistem
Pelaporan Pelanggaran - SPP (Whistleblowing
System - WBS), 2008). The disclosure of fraud has
become an early detection of company management
to prevent ongoing fraud (Khan, Anuar, & Mahzan,
2014). So that the fourth hypothesis in this study is as
follows:
H
4
: The whistleblowing system has an effect on
the fraud disclosure
2.5 Fraud Disclosure and Market Reaction
According to ACFE (2016), companies that are
indicated to have fraud can reduce their business
reputation so that it can cause losses to the company.
Disclosure of fraud and the use of financial statement
information have an effect on investor perceptions in
conducting investment risk assessments (Brazel,
