I have been the chief marketing officer for a prominent luxury brand for six years now. Though I am happy in the job, I was recently approached by a foreign retail company to head up the marketing division of its new Hong Kong subsidiary. The pay and benefits, not to mention the challenge, are all appealing, but there is one hitch. The company recently went through a transnational merger and, given the high failure rates of M&As, I am worried that if this goes wrong, my own reputation might suffer. Is it worth the risk?
