From the agency theory perspective, there are various control mechanisms to attenuate information asymmetries and information risk and to enable better supervision of managerial activity that mitigates the opportunistic behavior of managers, such as financial reporting quality and disclosure. Several studies have analyzed some of information asymmetries and information risk attenuate effects, such as the reduction of the cost of capital and cost of debt and access to the debt market and the effect on its conditions, i.e., lower cost, higher debt maturity and lower guarantees in bank financing. This study, examines the impact of financial reporting quality and growth opportunities on the capital intensity. The sample of this study, includes 134 companies listed in the Tehran Stock Exchange during the period 1392-1396 and for processing and testing hypotheses, panel data methodology is used. The results show that financial reporting quality has negative impact on the capital intensity. Also, it shows that growth opportunity decreases negative impact of financial reporting quality on capital intensity. Therefore designed conceptual model is confirmed.

The environment in which financial statements auditing is implemented, is complex and built upon inherently fragile foundations. On the one hand, auditor’ independence is one of the most important characteristics of providing independent audit services, and on the other hand, failure to adhere to it, is among the most important threats to independent audit profession. Many researchers have noted that the most important obstacles to auditors’ independence arise from financial issues. Fear of losing a client who pays for audit or non-audit service fees has a significant impact on an auditor's judgment. However, independence is, in fact, an abstract concept that cannot be observable directly and is often described as a mental state that is related to concepts such as impartiality, honesty, trust, and personality. On the other hand, "fear" has understandable concepts and meanings in the dictionary. However, while investigating the problem that many working auditors acknowledge it, using the information of financial statements and market and through identifying factors related to fear of losing a client, an empirical model has been proposed to measure it. For this purpose, the viewpoints of 14 academics and profession experts, the data from132 listed firms in Tehran Stock Exchange over the years 2005 to 2014, multivariate regression, factor analysis and two-sample t test were used. The investigations and reviews resulted in presenting a 17-variable model whose power was confirmed in supplementary studies. Presenting this model will lead to increased empirical research in the field of auditor’s independence, and subsequently, increased knowledge in the field. Also, this model can be used by audit profession to explain the determinants of fear of losing clients. Moreover, this model could help develop the literature on auditing in general, and could contribute to auditors’ quality, independence, and transfer in particular.

The fact that firm’s management in practice has the power of hiring and dismissing the auditor and paying his/her fees, along with recent failures of auditing, has increased critics’ concerns on the possibility of auditor acting based on the management’s interest under pressure. Using the viewpoints of experts of the practice and university and Friedman's test, while analyzing the problem that many working auditors acknowledged it and emphasizing management performance audit, this study attempted to identify the causes and ways of treating auditors’ fear of losing clients. The results showed that the low number of clients, the selection of auditors by the management, and multiplicity of small audit firms are the main causes of increased auditors’ fear of losing clients. On the other hand, merging small audit firms and forming large audit firms, creating an independent audit committee in the firm, and restricting the creation of new audit firms are the most important ways of reducing fear of losing clients.

Based on existing evidence, Successful companies’ most important assets are intangible – such as their human capital. However, few companies provide detailed information about this resource. Human capital reporting (HCR) can also be regarded as an instrument that affect company financial performance and ultimately increase firm value. In this article, Gamerschlag and Moeller’s model (2011) is used that describes cause-and-effect relationships between HCR and company financial performance. So, the main purpose of this study is to examine the impact of HCR on financial performance and value of companies listed in the Tehran Stock Exchange. The dataset includes 112 companies listed in the Tehran Stock Exchange during the period 1385-1389. The study finds no significant evidence of the effect of HCR on the firm financial performance, but HCR has a positive and significant effect on stock price and firm value. Also, findings suggest a positive moderating effect of company size on the relationship between HCR and stock price and between HCR and firm value. It is also found that financial leverage and debt maturity have significant and positive impact on HCR.
