According to Pranav Haldea, managing director of PRIME Database Group, "not all areas of the country are benefitting equally. Since the Act decrees that companies shall give preference to the local area, the more industrialised parts of the country are cornering a larger share."
Under the Companies Act, 2013, certain class of profitable entities are required to shell out at least 2 per cent of their three-year annual average net profit towards CSR activities. SRS RVK
