Shareholders are taking a hard look at value across the board, says senior editor Suzanne Miller as we launch The Deal magazine's fourth annual Most Admired Corporate Dealmakers survey. Beginning April 1, we ask you to take a hard look too. Rate the M&A records of the top-performing companies in five sectors on overall strategy, deal team quality, value and execution of deals. Last year, you chose 3M Co., Abbott Laboratories, Coca-Cola Co., Hewlett-Packard Co. and J.P. Morgan Chase & Co.. Who will you pick this year? For more on the survey, see Miller's article, "Who's the best?" - Mary Kathleen Flynn
