Regulation 62B defines key terms for corporate governance in relation to listed entities with listed nonconvertible debt securities: control and independent director adopt meanings from existing regulations; senior management is similarly referenced; and public private partnership is defined as an arrangement between a public concessioning authority and a competitively selected private special purpose vehicle concessionaire or by MoU. A proviso treats non executive directors (other than nominee directors) of certain body corporates and PPP entities as independent for this chapter.
