Price determination exception for public sector disinvestment where control changes; bank guarantees permitted for open offers. The amendment carves out an exception to the open offer price determination for disinvestment of a public sector undertaking by the Central or a State Government where there is a change in control, and permits unconditional, irrevocable bank guarantees from scheduled commercial banks-subject to Reserve Bank approval-as an alternative to cash for open offer obligations, provided such banks have an AAA rating on long term debt from a credit rating agency registered with SEBI.
