In the first chapter I investigate the change in operating performance, efficiency and value addition of US bank merger and acquisition after GLBA. I extend the previous research by combining all the previous methodology used in merger literature and added a new methodology namely Expected EVA improvement. I will test whether these performance metrics have similar results or the performance of merger vary depending on the measurements. I will also examine the factors that have significant impact on the change in the banks’ performance.

My results show that industry-adjusted operating performance of merged banks increases significantly after a merger.I also find that the acquirer expected EVA improvement increase significantly after the merger. Revenue enhancement opportunity appears to be more profitable if there exist more opportunity for cost cutting such as geographic focus and diversified merger. Product diversification merger increase the industry adjusted performance more than product focused merger. The efficiency or profitability of targets has either positive or no effect change in acquirer performance.

In the second chapter I examine how diversifying away from traditional lending activity into noninterest income has affected banks efficiency and value. Does this activity or product diversification affect the bank’s production efficiency and excess value? How does this efficiency translate into excess value for the firm or how excess value increase is related to diversification and efficiency? I find that diversifications significantly reduce the value of banks measured in excess value and vice versa regardless of which measures diversification or excess value I use. Both revenue and asset diversification also significantly reduce all measures of efficiency scores. But the impact of efficiency on diversification is mixed. Only efficiency scores computed based on variable return to scale have negative on revenue diversification and other efficiency scores have no impact on diversifications. I also find that increasing efficiency will increase the excess value of the banks significantly and vice versa. So increasing diversification will reduce the excess value and hence will lower the excess value or BHC with lower diversification will have lower excess value and are more efficient.
