Master's thesis is referring the importance and requirement of internal audit in middle sized enterprises. It summarizes theoretical basis for the implementation of internal audit's profession and its legislative environment. Thesis is focused on the analysis of the processes of administration and record keeping of leasing agreements in corporation. Based on the analysis, solutions and measures concerning internal controls are proposed. Goal of the Master's thesis is to refer the importance of establishing and evaluation of the internal control processes. Subject of internal audit are not only non-functioning processes but also internal controls, which can be well established and functioning but management has no feedback about their efficiency.

The aim of this work is to create a framework to classify internal controls due to the management level in which they appear, and to apply this framework to internal controls in a small organization. First, the reader is briefly introduced to the definition of control, types of control and the structure of control. Another part is a description of the established framework for the classification and subdivision of controls in terms of the levels of management. Each level of control is also clearly accompanied by the examples from the above documents. In the end, this system is applied to an organization that has almost no internal control system yet, and the framework of the controls at the individual levels is introduced.

Concern of this thesis is a topic of an IT audit on financial institutions. These institutions are subject to severe regulations and considering their purpose -- to provide financial services, it has to be maintained unconditional security of both their information system and data. Therefore, financial institutions belong to the group of the most common customers of IT audit services. Opening part is dedicated to the relationship between financial audit and IT audit. Their history is described until present days. Both local and international contemporary legislation is also described. Then the COBIT methodology is introduced as main methodology concerning IT auditing. Finally, conclusions about relationship between financial audit and IT audit are presented. Following part of this thesis introduce essential requirements on financial institutions controls that are specific for this sector. There are several kinds of assurances and audit is only one of them, so the following part is dedicated to the introduction of each kind with description of their specifics. In the last, practical, part the IT audit checklist for financial institutions is worked out.

The thesis deals with the internal audit and controlling and with implementation of these two disciplines in practise. Thesis is divided into two parts. The theoretical part deals with the definition of internal audit and controlling, describes the history, definitions, tools and the roles of these two disciplines. The practical part is focused on individual section of company and their evaluation based on the results of internal audit and controlling of information system.

The purpose of this research is to identify the implications of blockchain technology on the auditing profession. By conducting interviews with current professionals in the auditing profession, as well as those in academic with a background in auditing, primary data was collected to aggregate what potential effects will be on the auditing profession in the next five years and the next decade. The data includes assumptions of how the accounting major itself, the auditing planning phase, assumptions of risk, and audit completions will change with the developing technology. The goal of this research is a better understanding of how auditing will be affected by blockchain technology for students, current audit professionals, and those in academia. With the results, it was concluded that training of new and current employees will need to evolve with more emphasis on IT skills and analytical reasoning, blockchain's development is on a precipice of adoption within the next decade, and that there is a current gap regarding regulation of blockchain technology.

I examine the spillover effects of the 2013 revision to the U.K. audit report standard, the International Standard on Auditing (ISA) 700 (UK and Ireland), from firms subject to the regulation (i.e., Premium companies listed on the London Stock Exchange (LSE)), to firms not subject to it (i.e., those listed on the Alternative Investment Market (AIM) of the LSE). The new regulation requires increased disclosures in three areas: audit risks, materiality and the scope of the audit. I hypothesize that application of the new rules to regulated clients will result in changes in audit styles and auditor mindsets that would be transferred to other (non-regulated) clients. If so, such effect of the new regulation on audit outcomes – specifically improvement in audit quality - for regulated clients will spill over to non-regulated clients. Because I expect the auditor to be the conduit for the spillover, I examine the difference in changes in audit quality for two groups: (1) AIM clients in audit offices that audit both Premium and AIM clients and (2) AIM clients in audit offices that audit only AIM clients. The results show that AIM firms in the first group (i.e., AIM clients of audit offices that also have Premium clients) experience lower absolute discretionary accruals, reduced propensity to have small positive earnings, and are more likely to receive a modified opinion under the new regulation. However, there is no change in audit quality for the AIM client firms of audit offices with only non-regulated (AIM) clients. These results are consistent with audit quality benefits spilling over from regulated clients to AIM clients, brought about by auditor-level changes. Further analyses indicate that the audit quality spillovers are more prominent for AIM clients with greater audit complexity, AIM clients of large audit offices, and London audit offices. / Business Administration/Accounting

This study considers the ability of the audit team to configurally process information, that is, to piece together information cues held by individual team members and recognize the underlying pattern in the information. It also examines how the hierarchical structure of the audit team impacts the team's ability to process information and affects the quality of decisions made by the team. The study also considers the ability of a specific audit procedure, the fraud brainstorming session required by Statement on Auditing Standards No. 99, to overcome barriers to communication and improve team judgments in subsequent tasks. I recruited 57 dyads (114 professional auditors) from public accounting firms to complete an experimental instrument, and employed a 2x2 between-groups ANOVA, manipulating team structure (peer versus hierarchical teams) and the level of the counterfactual prime (team brainstorming session versus individual strategic prompting). I find evidence of a relationship between team structure and judgment quality, but interestingly it is in the opposite direction predicted. Research from other domains suggests differences in status within the hierarchical team may hinder communication and lead to process losses. However, I find the opposite to be true in the accounting domain. When auditors are paired in hierarchical dyads, the senior auditor assumes a leadership role, taking greater interest in the content of his/her teammate's workpapers, asking more questions, and motivating the staff auditor to volunteer a greater amount of information, which results in a higher quality judgment. Thus, this study provides initial evidence that the hierarchical nature of the audit team does not lead to the process losses documented in other domains as the assumption of a leadership role by the senior auditor allows the team to overcome any challenges inherent in the hierarchical structure. This study also considers the ability of the SAS 99 fraud brainstorming session, serving as a counterfactual prime, to lead to improved decisions later in the audit process. As predicted, the brainstorming session conducted during the planning stage of the audit increases the amount and quality of communication during the testing phase and leads to better judgments. These results are of importance for accounting firms as they determine which audit team members are required to participate in the brainstorming session. While a novice auditor may not make significant contributions to the planning decisions made during the brainstorming session, my study finds there are benefits from staff auditors participating in the brainstorming session, over and above what they are able to contribute to the session itself. Participation of staff auditors in the brainstorming session strengthens communication and enhances team-level cognition in subsequent tasks, improving the ability of the audit team to detect fraud throughout the course of the audit. These findings may be relevant for other forms of teamwork, including management teams, audit committees, and interdepartmental taskforces. / Ph. D.

This study examines whether auditor industry expertise in private clients influences audit quality of public client engagements in the United States. Private companies are significant to the U.S. economy as well as audit firms. I hand-collect auditors' private client information and construct a national, city, and joint national/city specialist designation and document a 17.9 to 47.3 (12.9 to 25.8) percent decrease in a public client's likelihood to misstate their financial statements (net income earnings management) when an auditor is a private client industry specialist. I then construct and test a city specialist measure using both private and public client data and find that it is economically stronger and more robust than the public only measure commonly employed by audit researchers. This study provides evidence of the importance of private companies to an audit firm's industry expertise as well as to researchers' use of city specialist measure in audit studies. / Doctor of Philosophy / This study examines whether auditor industry expertise in private clients influences audit quality of public client engagements in the United States. Private companies are significant to the U.S. economy as well as audit firms. I hand-collect auditors' private client information and construct a national, city, and joint national/city specialist designation and find that audit quality is higher for the audit firm's public clients in the same industry.

This dissertation examined the effects of interruption on auditor efficiency and effectiveness for one simple and two complex tasks within the audit domain. I evaluated these effects for novice and experienced auditors. In addition, I considered two ways in which the negative effects of interruption might be mitigated: varying an individual's interruption response strategy (immediate vs. negotiated) and the presence or absence of a memory-aid (notes). I investigated these phenomena using an internet-based experimental instrument. Subjects included both students and practicing auditors. My findings indicate that interruption hindered performance on certain complex audit tasks, and that it differentially affected auditor performance at two levels of experience. When interrupted, inexperienced auditors completed complex audit tasks less efficiently; experienced auditors completed them less effectively. In addition, experienced auditors who negotiated interruption completed a complex audit task more efficiently and effectively than those that responded to the interruption immediately. Furthermore, note-taking increased experienced auditor task efficiency on a complex audit task requiring judgment. These results suggest that auditors should limit task interruption when they are engaged in complex audit tasks. When task interruption cannot be avoided, auditors should consider negotiating a delay in the onset of an interruption. Finally, auditors who are interrupted while they complete a complex task requiring judgment should consider using notes to mitigate the deleterious effect of interruption on task efficiency. Participants also completed a post-experimental questionnaire which provided evidence about interruptions in the audit environment. The responses confirmed that auditors are frequently interrupted in practice. In addition, auditors preferred differing interruption response strategies dependent upon both the level of primary task complexity (easy vs. difficult), and the medium through which the interruption occurred (electronic vs. interpersonal). They chose interruption response strategies according to their place in the social hierarchy relative to the interrupter (client/boss vs. subordinate /friends/family). Finally, I found that interruption influences affect. Auditors reported significantly more positive affect reactions to interruption on easy tasks (e.g., alert, cheerful, friendly, happy and relaxed) and substantially negative affect reactions to interruption on difficult tasks (e.g., angry, hostile, irritated, nervous and tense). / Ph.

A common cliché found in annual reports is "our employees are our most important, valuable asset." While many companies claim human capital is an important asset and source of valuable earnings, there is nary a human asset found in financial statements. This research paper investigates the usefulness and importance of voluntary human capital disclosures. The 2 X 2 X 2 experiment manipulates firm financial performance, non-GAAP voluntary disclosures, and disclosure attestation to identify the extent to which human capital disclosures influence investor decision-making related to assessments of management credibility and firm value. The research described in this dissertation also investigates the interactive effects of auditor attestation on voluntary disclosure. The primary hypothesis examines whether firms providing strong human capital disclosures will have higher credibility ratings and stock price associations than firms not providing such disclosures. I find that when presented with human capital metrics, investors' assessments of credibility and firm stock price are attenuated by human capital disclosures, especially during periods of strong financial performance. Results also suggest investors key in on both non-financial and financial human capital metrics. Based on cognitive processing time, analyses indicate investors spend more time processing strong human capital disclosures. Another important hypothesis examines if firms receiving attestation services over voluntary human capital disclosures will have higher credibility ratings than firms not receiving such services. I find some evidence investors cognitively acknowledge the presence of auditor attestation reports when they are presented, and both credibility and stock price assessments are impacted by attestation services. Overall, the original research described here makes a contribution to the existing literature by providing unique insight as to how human capital information is viewed by investors. Current reporting standards focus on financial assets, physical assets, and technological/intellectual property. This can result in significant transparency issues when publicly traded firms fail to adequately disclose human capital risks. Organizations undoubtedly have substantial unreported human capital benefits and risks, which can have a potentially significant market valuation impact. The research conducted and reported in this paper illuminates the potential benefits of human capital disclosures to both internal and external firm stakeholders. / Ph. D.
