As everyone knows, there is nothing more precious to a banker than a league table. So they make great efforts to see they are composed properly. Thats why Asias top M&A bankers were glad to meet with Securities Datas M&A database manager James Susmann when he made a consultative trip to Asia yesterday. The New York-based Susmann was making his first trip to Asia to consult with local professionals on how the Asian M&A league tables could be improved.
