Roles on a trio of huge takeovers announced in a single day have boosted Bank of America Merrill Lynch and Evercore Partners in the second most valuable week of the year for mergers and acquisitions – albeit one of the quietest by number of deals.

Dealogic weekly figures show that from April 24 to April 29, M&A deals worth more than $97 billion have been announced, making it the biggest week for global M&A value since early February, when $118 billion-worth of activity was announced between January 31 and February 6.
