This study examines the relationship betweenCredit Risk (CRI)and earnings quality, and the moderating role of Key Audit Matters(KAMs) in this relationship. Using a sample of 112 companies listed on the Tehran Stock Exchange from 2013 to 2022, the study employs a descriptive-correlational methodology and regression analysis to test two hypotheses. The results reveal a significant positive relationship between CRIand earnings quality, with higher CRIleading to greater earnings management. Furthermore, the disclosure of KAMs is shown to moderate this relationship byenhancing transparency and audit quality, thereby reducing earnings management in companies with higher CRI. The study's findings provide valuable insights for auditors, regulators, and investors, particularly regarding the benefits of KAM disclosure in improving the reliability of financial reports. Limitations include the exclusion of financial institutions and banks, as well as unaccounted political and economic factors. Future research should explore the broader impacts of KAM disclosures on corporatedecision-making and risk management

The purpose of this research is to design a profit maximization model for companies using the theory of constraints. To collect information, library and field studies were used, according to the method of data collection, documents, interviews and questionnaires were used, so the current research method is mixed (qualitative and quantitative). The statistical population of the research in the qualitative part included experts, professors and specialists in the field of management accounting, 10 of whom wereselected by snowball sampling until theoretical saturation was reached, and primary data were collected through interviews and a questionnaire was designed. A questionnaire was included in the quantitative part as well. All managers and assistants of the finance and accounting departments of manufacturing companies admitted to the Tehran Stock Exchange were an unknown number. According to Cochran's second formula, 385 people were selected by available sampling. A questionnaire with 78 questions was used tocheck the research variables. Cronbach's alpha coefficient confirmed the reliability of the questionnaires, 10 interviewees confirmed the content validity of the questionnaires, and their construct validity was confirmed by confirmatory factor analysis. Then, the data obtained from the questionnaire was analyzed in two sections: descriptive statistics and inferential statistics. In the section on inferential statistics, the Kolmogorov-Smirnov test was used to check the type of data distribution in terms ofnormality or not, and then confirmatory factor analysis by LISREL 8.80 software. In order to check the construct validity of the questionnaire and to test the structural equation model with the help of Lisrel SmartPLS.03 software, it has been used to answer the research questions. The most important findings of the research showed that the components of identifying the limits of profit maximization, exploiting the limits of profit maximization, spreading the effect of profit maximization decisions, removing system limitations, and the process of continuous improvement of profit maximization, respectively, with a path coefficient of 0.41, 39 0.0, 0.43, 0.37, 0.40 have a positive effect on the theory of limitations

This study investigates the role of digital financial services in enhancing innovation within Iranian sports companies. The research follows a descriptive survey method with a quantitative approach and employs Structural Equation Modeling (SEM) for data analysis. The statistical population includes senior managers, financial managers, and IT managers of sports companies, as well as financial and technology experts in sports clubs and startups. The sampling method was stratified random sampling, and the sample size was determined as 200 participants using Cohen’s method, considering 10 latent variables in the model. Data collection was carried out through two standardized questionnaires with validated content and face validity confirmed by experts. Reliability was assessed using Cronbach’s alpha. The first questionnaire, digital financial services assessment, consists of 15 items across five components (digital financial technology infrastructure, digital payment services, digital banking, digital investment, and digital financial innovation).The second questionnaire, Innovation Assessment in Sports Companies, includes 15 items across five components (product innovation, process innovation, organizational innovation, marketing innovation, and strategic innovation). The Cronbach’s alpha scores were 0.899 for innovation and 0.794 for digital financial services. The findings reveal that digital financial services have a significant impact on various dimensions of innovation, including product, process, organizational, marketing, and strategic innovation. These services enhance transparency, reduce costs, and improve access to financial resources, thereby alleviating financial constraints and fostering innovation capabilities within sports companies
