Corporate governance has become an important topic after the financial crises that occurred in many companies and led to their collapse in the nineties of the twentieth century, and technological developments affected accounting and the appropriateness of financial reports. Many corporations used corporate governance concepts to acquire the trust of investors who value transparency and information sharing. The goal of this research is to look at the impact of corporate governance structures on financial reports quality and how it relates to the type of external auditor. The findings of the study show that institutional shareholder ownership has a positive and significant link with financial report quality, and that the auditor's view diminishes the relationship between institutional shareholder ownership and financial report quality. The study concluded that managers' ownership has a positive and important relationship with the quality of financial reports, and the auditor's statement has no effect on the relationship between managers' ownership and the quality of financial reports. The structure of the board of directors has a positive and important relationship with the quality of financial reports, and the auditor's statement has no effect on the relationship between the structure of the board and the quality of financial reports. Finally, the size of the council has a positive and important relationship. The auditor's comments reduce the relationship between board size and the quality of financial reporting.

Sustainability topics receive more attention, especially in the current era of globalization and rapid environmental changes and the effects of these changes on various business sectors and the need for these sectors to evaluate their performance on a continuous basis and achieve the desire of stakeholders. Whether internal or external, maximize their value achieved and improve their image towards their interest in sustainable development. The research aims at auditing the sustainable performance of the banking sector using one of the performance assessments means, a Sustainable Value-Added approach on a sample of banks listed in the stock market. Which disclose sustainability data in their announced reports and measure their efficiency for the three dimensions of sustainability (economic, social and environmental). The researchers reached at a number of conclusions, the most important of which was that all banks under discussion achieved economic and social efficiency. Only two banks have been able to achieve environmental efficiency due to the lack of adequate disclosure of these banks and the failure to take appropriate measures to reduce the environmental impact on the community. The study recommends the need for various business sectors to pay attention to all aspects of sustainability because of its significant impact on maximizing the value of the facility and preserving the available energies for future generations. In addition, banks' management should develop specific programs to develop the expertise and skills of internal auditors in the environmental and social field.
