The Ministry of Finance on October 29 issued a detailed clarification defending the valuation and bidding process for the strategic restructuring of IDBI Bank, stating that special powers delegated to the Core Group of Secretaries on Disinvestment (CGD) allowed it to determine the "best-round" procedure and boost the overall transaction value by Rs 3,917 crore. The procedure for the "best-offer" round was determined by the CGD itself, the ministry said.
