Independent auditing effect on investment decisions of institutional investors

It is very important for investors to get accurate and reliable information so that they can earn large amounts of revenue from decisions they make. However, in recent years, population growth, the expansion of the economy and the complexity of economic life have reduced the credibility of the information presented. The need for accurate and reliable information leads to requests for accounting and auditing activities. The independent audit, which increases the credibility of the information provided by the company and the reports it prepares, is also important in terms of investors, lenders and business owners. The aim of this study is to determine whether institutional investors are influenced by independent audit practices and the results of their investment decisions, and if so, how effective they are. In this study, firstly information about institutional investors is given and the factors affecting investment decisions are mentioned. Later, information on auditing was included. In the last part of the study, a questionnaire was applied to the managers of institutional investors consisting of banks, brokerage houses, investment trusts and portfolio management companies registered in the Turkish Capital Markets Association (TCMA) to investigate whether any independent auditing practices and results had any effect on investment decisions of institutional investors. As a result of the analyzes made, it has been determined that institutional investors consider the independent audit report and its results together with the investment decisions of the independent audit financial tables and have effects on their decisions.


Introduction
It is a big deal in terms of the fact that the financial statements prepared by the companies show reliable and timely information.Macroeconomic indicators and the financial position of the investor are the determinants of investors' decisions.Investors, in particular, decide whether to invest in the shares of the enterprises by examining the financial position and results of operations (Coşkun et al., 2013: 11).Instead of small investors, institutional investors are called specialized financial institutions that manage savings in a collective way in terms of the level of risk, return and target of investment.
The presence of new financial instruments in the economy and the feeling of the effects of technological developments on the economy increase the demand for reliable information.In particular, the reliability of the information that they obtain from investing in investments for investors is of utmost importance.Investors should investigate that the information disclosed in the name of the decision will be as reliable as possible.In verifying the reliability of the information disclosed, it is a common practice to check this information by an independent person.Integrity, correctness and impartiality must be audited and verified in order for information to be accepted as reliable information for decision-making (Erdoğan, 2002: 62-63).
At this point, appropriate and sufficient independent audit evidence to provide a reasonable assurance of conformity and accuracy between the financial statements and other financial information formed as a result of the economic activities of an entity and previously established criteria and the application of appropriate independent audit techniques recommended in the independent audit standards, And an independent audit, whose results are linked to the report, has emerged (Kardeş -Selimoğlu et al., 2011: 5).
The main purpose of the research is to demonstrate whether the institutional investor has an independent audit on the investment decisions and the effect of the results.The study also explores the perception differences between independent brokerage firms, portfolio management companies, investment partnerships, and bank, which are among the institutional investor types, to consider independent control when making investment decisions.However, it is important to investigate the contribution of the literature to the measurement and evaluation of the interaction between independent audit results and practices and institutional investors who are making investment decisions.
This study consists of a total of four sections except for the introduction and conclusion section.In the first part of the study, information about institutional investors is given.In the second part, independent audit is examined.In the third chapter, similar studies are introduced in the literature review.In the fourth part, the scope of the research, the method applied in the research, the analysis of the research data, findings and interpretations are given.Finally, in the light of the findings obtained from the survey, the results were evaluated and suggested.

Factors affecting institutional investors and investment decisions
Investors are classified as institutional investors and individual investors according to the party to which the funds are directed.Individual investors often do not have the opportunity to follow the market constantly, act according to their developments and manage their portfolios professionally when they do not have the necessary technical equipment and sufficient expertise.Portfolios created with individual savings that do not reach sufficient size are often referred to as risky portfolios.It is also not possible for individual investors to be distracted because they can invest only a few borrowing shares or shares with limited savings they have.As such, institutional investors have been formed in capital markets as collective investment institutions (Akın and Ece, 2011: 12).
Institutional investors who take the role of collecting the fund surplus that individuals make positively between the income they earn and the expenditures they incur and the large amount of these funds being evaluated within the legal boundaries try to operate in order to diversify the funds they collect through individual investors in terms of investor groups and to provide the highest return (Usul and Kocabıyık, 2010: 65).Institutional investors include mutual funds, private pension funds, investment trusts, brokerage houses, portfolio management companies, insurance companies, social security institutions and banks.
Institutional investors are the most important component of the demand trend of capital markets in developed countries because they evaluate the high level funds they obtain from various sources by channeling them to capital market instruments according to expert staff and return expectations and risk expectations (Zor and Aslanoglu, 2005: 185).Institutional investors can play an important role in the development of financial markets as well as contribute to overall domestic economic growth.Institutional investors dynamically influence both financial sector growth and economic growth (Harichandra and Thangavelu, 2004: 7-8).
However, institutional investors are generally considered to have a positive effect on share prices of the companies they invest in.This effect is achieved through different mechanisms.Institutional investors reduce information asymmetry between the firm and other investors.It improves the corporate governance of the companies.It also contributes to the liquidity of companies (Huyghebaert and Hulle, 2004: 690).
Investment decisions are one of the most important tasks and responsibilities of the finance function.In order to be able to make a positive decision about any investment topic in terms of business management, the profit to be provided by this investment should meet the cost that it will cause.However, investment should provide profit for the entrepreneur (Babuşcu and Hazar, 2007: 109).Factors affecting investment decisions can be classified as economic factors, political factors, information sources, socio-cultural factors and psychological factors.

Independent audit
In recent years, with the increase of economic activities, the reliability of the information provided by the enterprises due to the more complicated transactions, the surplus of the data and the approaches of the informants have been questioned more and the needs of the information users have become more reliable and widespread (Kardeş-Selimoglu et al., 2011: 2).Relevant and reliable information needs have led to accounting and auditing services.For example; an investor who wants to invest money in stock, a bank that has to give credit to the business, a public institution that is trying to get the right to make a healthy decision definitely needs reliable information (Ataman et al., 2001: 13).
In the business world, it is very difficult for information users to get the information they desire first hand.When knowledge is obtained from others, it is more likely that it is intentionally or otherwise misrepresented.When there is a conflict of interest between the information claimant and the information provider, there is a risk that the information presented is misleading.Here are three things that can be done against the riskier.The first is to obtain and control the desired information on its own; second, to rely on the other side to enter into a risk; and the third is to resort to independent audit opinion (Kardeş-Selimoğlu et al., 2011: 2).
Independent auditing is the audit and compliance and performance audits of the financial statements of the enterprises by an auditor or auditor who, within the scope of an audit agreement, provide the professional audit service to the clients, who work on their behalf as a self-employed person or perform their duties as an auditor.Financial audit is the main objective of independent audit (Uzun, 2007: 4).
An audit is the process of providing assurance about the accuracy of the information taking place in the financial statements prepared in accordance with generally accepted acounting principles or other rules.The responsibility of the financial statements of a company belongs to the management of the company (Soltani, 2007: 4).
Based on these definitions, we can list the main features of the audit as follows (Güçlü, 2008: 1-2): • Auditing is a process: It covers a certain period.
• Interested in economic activities and other events.
• Auditing has predetermined criteria.
• The audit must be impartial.
• The most basic principle of auditing is to collect evidence and evaluate them.
• Auditing is obliged to report the results to the addressees.
Auditing enhances the reliability of information provided to investors, business owners, lenders and other users.In short, the task of the auditor is to detect mistakes and deceptions.The results of the audit practices appear in the audit report.Today, the primary goal of auditing is to approve the correctness of financial statements.Auditing not only reduces the cost of exchanging information between managers and shareholders as an important part of the capital market framework, but also points to a marketplace where information is trustworthy (Salehi, 2010: 70-82).

Literature review
In general, independent audit and its quality with the independent audit report and the internal audit report are found in a number of literature studies examining the effect on investment and lending decisions as well as the effect of investor confidence and stock return.There are studies in the literature that show that auditor opinion is important and should be taken into account when trying to measure the impact of auditor opinions on investment decisions and credit approvals (Gómez-Guillamón, 2003;Holt and DeZoort, 2009;Lai, 2009;Mansi, Maxwell and Miller, 2004;Ruiz-Barbadillo et al., 2004;Salehi, 2010).As a result, it is stated that these studies take into account the auditor's opinion on investment decisions and credit approval.Companies that have significant investment opportunities have been audited by 5 major audit companies; it is also emphasized that the audit report is an important parameter when making investment decisions.
On the other hand, there are also some studies in the literature that are opposite of the results above.Studies in which the audit reports and audit opinions have no effect on the decision makers are also included in the literature (Kabajeh et al., 2012;Martinez et al., 2004;Ogneva & Subramanyam, 2007;Tahinakis et al., 2010;Moradi et al., 2011;Anvarkhatibi et al., 2012).The results of the studies show that both company managers and lenders think that the auditor's report is not completely unbiased, inadequate and inappropriate when making decisions.In addition, lenders declare that these reports do not make a positive contribution to their credit decisions.In addition, the findings of the studies show that conditional audit reports do not have the value of information for investors.They also state that the audit report for investors is not a part of the decision-making process.Lastly, studies show that auditor opinions do not have a significant effect on stock prices and returns.These differences can be caused by the time, country or the methods of the studies.
In general, when the literature is examined, no study was encountered that on how much institutional investors consider independent audit in investment decisions.Than, the views of managers of institutional investors including banks, brokerage houses, investment trusts and portfolio management companies registered with the Turkish Capital Association (TCA) have been consulted in order to determine whether the independent auditing practices and results are influential on the investment decisions of the institutional investor and if so, to determine the degree.

A research to determine the effect of independent auditing on investment decisions of institutional investors
In this section, the purpose and the importance of the research, the scope of the research, the method applied in the research, the hypotheses of the research, the analysis and findings of the research data are included.

The purpose and the importance of the research
The main purpose of the research is to determine whether the results of the independent auditing are effective for the investment decisions of the institutional investor and if so, to determine the degree.The brokerage house, which is one of the institutional investors, is to investigate perception differences related to independent auditing while it decides to invest among the portfolio management company, the investment partnership, and the bank.It is also the purpose of the research to develop recommendations in order to demonstrate the importance of independent auditing.Institutional investors are required to research the results of independent audits in investment decisions, and to contribute to the literature by measuring and evaluating the effects of their applications.

The scope of the research
As of October 2015, 228 institutional investors (banks, brokerage houses, investment trusts and portfolio management companies) registered in the Turkish Capital Association (TCA) constitute the scope of the research.17 of the institutional investors were temporarily suspended.In this case, 211 institutional investors registered with TCA also constitute the main mass of the research at the same time.The data source in the study is the managers in different positions.Questionnaires were sent via e-mail to the 211 institutional investors active in TCA, the main mass of the research.The names of the banks, brokerage houses, investment trusts and portfolio management companies and the telephone numbers, open addresses and / or electronic mail addresses of these companies were obtained from the internet addresses of the CMB and TCA and the internet addresses of the companies.By linking to a web page given in the e-mail, companies are directed to the questionnaire; Answers are recorded in the same database.So they did not have to send e-mails to send their answers.In order to increase the response rate of the questionnaire, necessary correspondences were obtained from TCA.A total of 211 institutional investors registered with TCA were sent a questionnaire and 118 questionnaires were found suitable for analysis.In this case, the return rate is approximately 56%.

The method of the research
Following the theoretical study in the research, the survey method was used as the method applied to measure the effect of independent auditing of institutional investors on investment decisions.Since there is no scale related to the research topic, the questions on the questionnaire were prepared by taking the literature survey results into consideration, especially by making use of Gomez-Guillamon (2003), Adeyemi and Uadiale (2011), Leung and Chau (2001), Best et al. (2001) and Fadzly and Ahmad (2004).The prepared questionnaire was completed in May 2015 after the examination of experts and a pilot study on bank managers in Tokat.
The first section of the two-part questionnaire is a closed-end, 5-point Likert scale for determining how much institutional investors take into account independent control of investment decisions.There are 26 expressions in the first chapter.1-7 expressions are related to Hypothesis 1, 8-15 expressions are 2. Hypothesis related, 16-21 expressions are related to 3. Hypothesis, and 22-26 expressions are related to the fourth hypothesis.In the second part, there are 9 questionnaires including demographic characteristics of participating institutional investors and participant information.In this case, the questionnaire consists of 26 expressions and 9 questions.Surveys are open on the internet from June 1, 2015 to October 8, 2015.

Findings of the research
The analysis of the study was first started with reliability analysis and the reliability of the questionnaire was measured.Then frequency analysis was done.
To test the research hypotheses, a normality test was performed to determine whether to use parametric or nonparametric tests.Mann-Whitney U test was applied to the hypotheses firstly after Kruskall Wallis test.
Research data were analyzed using SPSS (Statistical Package for the Social Sciences) and Microsoft Office Excel programs.Reliability analysis was done first.It is called reliability that reveals the consistency of all the questions in a measurement (test, questionnaire) with each other and the homogeneity in measuring the problem studied (Akgül & Çevik, 2003: 434).The Cronbach alpha coefficient was used to measure the reliability of the questionnaire.The Cronbach Alpha Coefficient, which investigates whether the whole of the scale in question is homogeneous in order to explain its homogeneity, shows the similarity and closeness of the questions in the cases where the individual scores are collected by the answers given to the questions.The ranges and the reliability of the scale where the Alfa coefficient can be found between 0 and 1 are as follows (Akgül & Çevik, 2003: 435-436): If 0.00 ≤ α <0.40, the scale is not reliable.If 0.40 ≤ α <0.60, the scale is low reliability.If 0.60 ≤ α <0.80, the scale is mostly reliable.If 0.80 ≤ α <1.00, the scale is highly reliable.
The Cronbach Alpha coefficient obtained in the study is 0.928.This figure indicates that the survey is highly reliable.Then frequency distributions were given according to the characteristics of institutional investors who answered the questionnaire.Subsequently, brokerage house managers, investment partnership managers, portfolio management company managers and bank managers are presented with views on statements prepared according to the 5-point Likert scale.
It has been determined whether parametric or nonparametric tests should be applied to the research data by testing normality.The Shapiro Wilks test should be used when the number of subjects is less than 29 in the normality test, and the Kolmogorov-Smirnov test should be used when the number of subjects is more than 29 (Akgül & Çevik, 2003: 99).The results obtained from the normality test for the four hypothesis-related groups (Brokerage House (43), Investment Trust (24), Portfolio Management Company (21), Bank (30)) did not meet the normal distribution (p <0,05).This resulted in the need to use non-parametric tests.
In the test of research hypotheses, Kruskall Wallis test was used to compare nonparametric tests between three or more groups with continuous variables and then to show which group is different from the other group; Mann-Whitney U test was used to test significant differences between two independent groups.

General characteristics of institutional investors participating in the research
73.7% of the managers of institutional investors who responded to the survey were male and 26.3% were females.73.3% of the institutional investor managers are in the age range of 20-40, 26.7% are in the 40 and above.36.4% of the institutional investor managers work in the Brokerage House, 25.4% in the Bank, 20.3% in the Investment Trust and 17.8% in the Portfolio Management Company.25.4% of institutional investor managers are experts, 23.7% are managers, 18.6% are portfolio managers, 9.3% are managers, 8.5% are directors, 5.9% are board members, partners, general managers, Senior manager consisting of assistant general managers, 4.2% assistant manager, and lastly 4.2% senior executive.49.2% of institutional investor managers have between 1-10 years, 38.1% between 11-20 years and 12.7% more than 21 years.Institutional investor managers account for 60.2% of the bachelor's degree, 35.6% hold a master degree and 4.2% hold a doctorate degree.

Perceptions of institutional investors using independent audit in investment decisions
In this section, for the investment decisions of the institutional investors consisting of brokerage houses, investment partnerships, portfolio management companies and banks participating in the research; the information contained in the independent audit report of the company to be invested, the audit opinion, whether the audit was carried out by 4 major audit firms, and the perceptions of the extent to which the independent audited financial statements are effective are presented.
In this part of the study, participants in the survey were asked to indicate whether they participated in the 5-point Likert scale and prepared statements to measure how much they considered independent control of investment decisions.The weighted average for each expression was calculated by giving the weight from 1 to 5, with the answer "I do not Participate Totally" in the direction of the answers obtained and 1 to say "I Participate Totally".

Analysis of the differences among institutional investors' measures of using independent audit in investment decisions
In this part of the study, the existence of the differences in the application of independent auditing in investment decisions of brokerage houses, investment trusts, portfolio management companies and banks was examined.Here, the perception of the brokerage houses, investment partnerships, portfolio management companies and bank managers responding to the questionnaire are examined by matching.The findings of the statistical analyzes were revealed and the findings of the tested hypotheses are explained.a) Analysis of the differences among institutional investors' perceptions of investment decisions using the information contained in the independent audit report The perceptions of the brokerage houses participating in the survey, investment trusts, portfolio management companies and banks' perceptions regarding the investment decisions used in the independent audit report are given in Table 1.3.81 3.95 3.90 3.80 4. I benefit from the independent audit report, while I assess the future profitability of the new investments of the company that I will invest in.
3.53 3.91 3.80 3.86 5.I make use of the independent audit report when I estimate the future cash flow volume or risk of the company.
3.62 4.04 3.76 3.96 6.An independent audit report may contain important information about a firm's ability to sustain its existence.
3.83 4.29 3.85 3.90 7. The audit report is sufficiently useful and understandable to make informed decisions.

Research Hypothesis 1
H0: There is no statistically significant difference among perceptions of institutional investors regarding the effectiveness of the information contained in the independent audit report in investment decisions.
H1: There are statistically significant differences among the perceptions of institutional investors regarding the effectiveness of the information contained in the independent audit report in their investment decisions.
The 1 hypothesis is tested by calculating a dimension of 7 words mentioned.With this dimension, participants' mean scores for 7 expressions are determined.Kruskall Wallis test was applied for the hypothesis and the results are given in Table 2 below.According to the results of the Kruskall Wallis test, as shown in Table 2, there is no statistically significant difference among the perceptions of the broker managers, investment trust managers, portfolio managers and managers regarding the information contained in the independent audit report.In other words, the H0 hypothesis has been accepted.Here, although the average of brokerage managers is slightly lower than that of investment trust managers, portfolio management firms and bank managers, it does not make any statistical sense.Here, institutional investors have stated that they use the information contained in the independent audit report on their investment decisions at the same level and use them in investment decisions.

b) Analysis of the differences among institutional investors' perceptions of taking the audit opinion type into consideration in investment decision making
Averages for the perception of brokerage houses participating in the survey, investment trusts, portfolio management companies and banks to consider the audit opinion type in investment decisions are given in Table 3.

Research Hypothesis 2
H0: There is no statistically significant difference among institutional investors' perceptions of the impact of audit opinion on investment decisions.
H1: There are statistically significant differences among the perceptions of institutional investors regarding the effectiveness of the audit opinion track in investment decisions.
The second hypothesis is tested by calculating a dimension of 8 words mentioned.With this dimension, participants' averages for 8 expressions between 8-15 are determined.The Kruskall Wallis test was applied for the hypothesis and the results are given in Table 4 below.As seen in Table 4, there is a statistically significant difference in the level of 10% significance among the perceptions of the broker managers, investment trust managers, portfolio managers, and bank managers on the information contained in the independent audit report, according to Kruskall-Wallis test results.In other words, the H0 hypothesis has been rejected.
The Mann Whitney U test was conducted to determine perception differences between the two specific groups.The Mann Whitney U test was conducted between brokerage house managers, investment trust managers, portfolio management company executives and bank managers.The results of the Mann Whitney U test in general are shown in Table 5 below.As shown in Table 5, the Mann Whitney U test results for Hypothesis 2 are shown above.According to the Mann Whitney U test results, there is a statistically significant difference in the level of 5% significance between brokerage houses and investment management managers considering the audit opinion type when making investment decisions.
Yet again, according to the Mann Whitney U test results, there is a statistically significant difference in the level of 5% significance between investment partnership and portfolio management company managers' decision on audit review.
In this respect, it was concluded that there was a difference between the opinions of the brokerage house, the investment partnership and the managers of the portfolio management companies regarding the view of the audit opinion when making investment decision.Here are the managers of investment partnerships; Portfolio management company executives, bank managers, and brokerage managers.The brokerage house managers are the ones that are least considered.

c) Analysis of the differences among the perceptions in investment decisions of the institutional investors related to the auditing by the 4 major audit firms
The averages for the perception of the brokerage houses participating in the survey, investment trusts, portfolio management companies and banks to be considered by the 4 major audit firms to audit the investment decisions are given in Table 6.

Research Hypothesis 3
H0: There is no statistically significant difference between perceptions of institutional investors regarding the effectiveness of the audit by the 4 major audit firms.
H1: There are statistically significant differences between the perceptions of institutional investors about the effectiveness of the audit by the 4 major audit firms.
The 3th hypothesis is tested by calculating a dimension of the mentioned 6 expressions.This dimension determines the average of the participants' six expressions, 16-21.Kruskall Wallis test was applied for the hypothesis and the results are given in Table 7 below.As seen in Table 7, according to Kruskall-Wallis test results, there is a statistically significant difference in the level of significance among the perceptions of the broker managers, investment trust managers, portfolio managers and managers regarding the information contained in the independent audit report.In other words, the H0 hypothesis has been rejected.
The Mann Whitney U test was conducted to determine perception differences between the two specific groups.The Mann Whitney U test was conducted between brokerage house managers, investment trust managers, portfolio management company executives and bank managers.The results of the Mann Whitney U test in general are shown in Table 8 below.The Mann Whitney U test results for the 3rd hypothesis are shown above, as shown in Table 8.According to the Mann Whitney U test results, there is a statistically significant difference at the 1% level of significance between brokerage houses and investment partners who consider investment decisions made by 4 major audit firms in charge of investment decisions.
According to the Mann Whitney U test results, there is a statistically significant difference at the 10% level of significance between brokerage firms and bank managers considering that they are made by 4 major supervisory firms that audit the investment decisions.However, according to the Mann Whitney U test results, there is a statistically significant difference in the level of significance of the investment partnership and portfolio management companies considering that they are being conducted by 4 major audit firms that audit the investment decisions.
Finally, according to the Mann Whitney U test results, there is a statistically significant difference between the portfolio management company and the bank managers at the 1% level of significance, considering that they are being conducted by 4 major audit firms that audit the investment decisions.
In this respect, it was concluded that there were differences between the opinions of the brokerage house, investment partnership, portfolio management company and bank managers regarding the decision of the 4 major audit firms to audit the company to invest while giving investment decision.Here, whereas the investment partnership managers stated that they considered that the investment decisions were made by four major audit firms, the managers of the portfolio management company stated that they have not considered.

d) Analysis of the Differences among the Perceptions of Institutional Investors on the use of Independent Audited Financial Statements in Investment Decisions
Table 9 summarizes the averages of the brokerage houses participating in the survey, investment trusts, portfolio management companies and banks' perception of their investment decisions using their independent audit financial statements.Research Hypothesis 4 H0: There is no statistically significant difference between the perceptions of investment decisions of the institutional investors and the effect of the financial statements that were audited by independent auditors.

H1: Institutional investors;
There are statistically significant differences between the perceptions of the investment decisions and the effect of the independent audited financial statements.
The 4th hypothesis is tested by calculating a dimension of 5 expressions mentioned here.With this dimension, participants' averages for 5 expressions between 22-26 are determined.Kruskall Wallis test was applied for the hypothesis and the results are given in Table 10 below.According to the results of Kruskall-Wallis test, as shown in Table 10, there is no statistical difference among the perceptions of brokerage managers, investment trust managers, portfolio management managers and bank managers regarding the use of independent financial statements in their investment decisions.In other words, the H0 hypothesis has been accepted.Here, although the average of portfolio managers is slightly lower than that of investment trust managers, brokerage managers and bank managers, it is not statistically significant.However, institutional investors have stated that they use these statements in their investment decisions at almost the same level as statements about the use of independent financial statements in investment decisions.Only the portfolio management company directors use these tables in a close proximity.

Conclusion
The fact that individual investors do not have sufficient knowledge accumulation and that there is a limited number of investment vehicles that they can invest because their savings are at a certain level are an obstacle to the dissemination of risk.Due to these and similar reasons, institutional investors who have the necessary technical equipment and sufficient expertise, follow the bazaars of the markets, take positions according to their developments and manage their portfolios in a professional manner have been formed.Institutional investors fulfill their functions by directing the large amount of funds they collect from individual investors to the capital market instruments through the professionally manageable staff of the portfolio.
It is a very important issue for investors to reach accurate and reliable information in order to make the right decisions.The information they use must be relevant and reliable so that they can benefit significantly from the decisions they make.In recent years, the growth of societies, the increase of economic activities and the increasing complexity of the economic life are decreasing the reliability level of the information presented.The need for relevant and reliable information has revealed the demand for accounting and auditing activities.Independent auditing, the period during which information about the economic activities and events of the company is collected in an unbiased manner to determine and report conformity with previously established and accepted criteria and to be communicated to the information users through a report of the evaluation and conclusion, enhances the reliability of information provided to investors, business owners, lenders and other related users.Independent auditing, which affirms the accuracy of certain financial statements, draws attention to the reliability of information provided by management.
In the direction of our research whose main aim is to determine whether the independent audit applications and results influence on the investment decisions of the institutional investors, according to the findings obtained as a result of the survey conducted to the institutional investors of the Turkish Capital Markets Association, brokerage managers, investment trust managers, portfolio management company managers and bank managers have stated that they have used this information in making investment decision by participating at the same level in the expressions related to the usage of the information in the audit report for investment decisions.Even if the institutional investors use the information contained in the independent audit report in their investment decisions, they were undecided on the positive side that the independent audit report was sufficiently useful and understandable.
According to the analysis results, investment partnership managers are more concerned about the audit opinion on investment decisions than portfolio managers, bank managers and brokerage managers.The managers of the brokerage houses are unstable in this respect.Nevertheless, it was the result that auditor opinions that were negative and refrained from commenting affected the investment decisions of institutional investors more than the positive and conditional audit opinions.In addition, while bank managers participated in the audit opinion that it had an impact on the company's share prices, others were unstable.
According to the analysis results, while the investment partnership managers state that for their investment decisions, they consider the audit by 4 big audit firms for the company that they will invest in, the portfolio management company managers states that they do not consider this.Brokerage house and bank managers have expressed an unstable situation in this regard.Only the investment trust managers are involved in thinking that the first four major audit firms are composed of more competent, more specialized inspectors and that their activities and results are more reliable.
According to the analysis results, the brokerage house managers, investment trust managers, portfolio management company managers and bank managers were attended at almost the same level of the expressions about the use of the independent audited financial statements in the investment decisions and they stated that they use these tables in investment decisions.Only the managers of the portfolio management companies have revealed a near-uncertainty in this matter.The brokerage house, investment partners and bank executives stated that they have confidence in the audited financial statements for the investment decision, while the managers of the portfolio management companies are unstable about trust.
As a result of the findings obtained, institutional investors, including brokerage houses, portfolio management companies, investment partnership and banks, which are included in the research, evaluate the investment decisions taking the information that may be useful for them in the audit report into consideration.
When investing in a company, this information affects their attitudes.Although this is not the case at all, it is concluded that the independent audit report is indeed beneficial and useful, as well as affecting investment decisions.This demonstrates the independent and authentic assurance of institutional investors.The fact that the audit is conducted by four major audit firms, which is used as one of the quality criteria of audit in the literature, is not so important for institutional investors when making investment decisions.Finally, we can say that independent audit practices and results provide an information value to the institutional investor.
The result is while showing similarity to the results of the studies performed by Gomez-Guillamon (2003) and Salehi (2010); on the other hand differs with the results of the studies conducted by Anvarkhatibi et al. (2012) andMartinez et al. (2004).These differences can be caused by the time of the studies, countries or the methods applied.
This study has been analyzed in terms of the opinions of brokerage houses, investment trusts, portfolio management companies and bank managers registered in the Turkish Capital Association in Turkey.In future studies, researchers can create a larger sample, or can include other institutional investors in the sample.It is also possible to examine the extent to which individual investors use independent audit practices and results in their investment decisions.
