Ever since the word corporate social responsibility came into the purview, it has been unceasingly changing its form in one way or another. It has come a long way from philanthropy to the mandatory regulation for the companies. The significance of CSR in public sector undertakings has been considered as the core matter as these enterprises are the major revenue generating units of the country. The purpose of this study is to determine the degree and the pattern of the CSR expenditure by Oil Sector Public companies corresponding to the mandatory guidelines of Section 135 of Companies Act, 2013. The sample of six companies has been considered to carry out an analysis for the period of four years post an implementation of Companies Act, 2013 ranging from 2014-15 to 2017-18. The data have been collected from the secondary sources and the descriptive analysis has been done through percentages, tables etc. It has been found that inconsistent profits and absence of common policy on handling unspent amount of CSR affects the sheer information on the CSR performance of the companies. Also, the expenditure towards various initiatives is concentrated on a few areas like healthcare, education and rural development. It has been suggested to derive a common policy for treating unspent amount and present its usage more transparently. Further the measures should be taken to maintain consistency in profits and the CSR expenditure should be devoted to more areas rather than concentrating on confined activities.
