As per Reg 3 of SEBI (Prohibition  of  Insider  Trading) Regulations, 2015, what is the purpose of the provision regarding "legitimate purposes"?

As per Reg 3- Communication or procurement of unpublished price sensitive information. (1)No insider shall communicate, provide, or allow access to any unpublished price sensitive information, relating to a company or securities listed or proposed to be listed, to any person including other insiders except where such communication is in furtherance of legitimate purposes, performance of duties or discharge of legal obligations. NOTE:This provision is intended to cast an obligation on all insiders who are essentially persons in possession of unpublished price sensitive information to handle such information with care and to deal with the information with them when transacting their business strictly on a need-to-know basis. It is also intended to lead to organizations developing practices based on need-to-know principles for treatment of information in their possession. (2)No person shall procure from or cause the communication by any insider of unpublished price sensitive information, relating to a company or securities listed or proposed to be listed, except in furtherance of legitimate purposes, performance of duties or discharge of legal obligations. NOTE:This provision is intended to impose a prohibition on unlawfully procuring possession of unpublished price sensitive information. Inducement and procurement of unpublished price sensitive information not in furtherance of one’s legitimate duties and discharge of obligations would be illegal under this provision.
