Abstract: Growth synergies have been obtained by Kotak and hence the merger has been a success. Having evaluated the Cost-Benefit Analysis, we obtain that an increase of profit with the benefits including the presence in SME and deposit base strengthening are outweighing the costs in the merger. Additionally, the AT Kearney synergy curve shows us that the initial IT cost and documentation have been short-term issues as with time, the cost efficiencies have expanded as economies of scale was obtained and hence growth synergies would be resulted.
