The data of financial ratios are mainly obtained from the Indonesian Capital Market Directory (ICMD) from year 2003 to 2013. The method used to answer the hypotheses is Paired T Test, the synergy is then measured by examining some pre- and post-merger and acquisition financial ratios (5 years before and 5 years after).
