Today, the problems and ways of improving the companies' corporate reporting and confirming their importance are among the most discussed topics in the academic world, both in Russia and globally. The existence of a wide range of research papers, as well as tools for evaluating non-financial information of companies, indicates the significant role of non-financial factors for the global society. However, it is still questioned whether these factors affect the market value of companies. According to the RSPP, the disclosure of non-financial information in the companies' annual reports allows users to identify leaders, helps to strengthen the reputation and investment attractiveness of these companies, and serves to promote the culture of responsible business conduct. In this work, the influence of non-financial factors on the market capitalization of companies in the oil and gas sector was studied using the model of correlation of factors with the calculation of the Pearson and Spearman coefficients. The data about the market capitalization of the three largest Russian companies in this sector, Gazprom, Gazprom Neft, and LUKOIL, were taken from publicly available sources. To find a correlation between the calculated indices and the market capitalization indicator, it was assumed that the company's market capitalization of the current year would be influenced by the indices of non-financial factors calculated according to the data of the previous year. It has been proved that there exists a certain connection between non-financial factors (index of ecological effectiveness; index of economic development; index of social influence) and the company's market value. However, the results of the analysis showed that political factors determine the capitalization of oil and gas companies in Russia to a greater extent at the present stage.

It is well known that there are many reasons for economic entities to distort their financial statements deliberately. It is a general practice, that reporting becomes the subject for management's manipulation. For example, top staff seeks to reduce the tax base by undercharging the profits in accounting (financial) statements. It expects to attract the maximum number of investors as their positive expectations have a beneficial effect on the growth of the market value of shares and the strengthening of the position of the economic entity in the market. Illegal actions misinform the users and mislead them. Distorted reporting also has a negative impact on management decisions, and it jeopardizes the existence of the company.
