The new Takeover Code of 2011 introduced several changes from the previous 1997 code:
1. The threshold for triggering an open offer was increased from 15% to 26% shareholding in the target company.
2. The minimum size of the open offer was increased from 20% to 25% of the total shares of the target company.
3. Non-compete fees paid to promoters of the target company are no longer permitted.
The new code aims to provide greater protection to minority shareholders and ensure fair share acquisition during takeovers.
