By Sinead Carew NEW YORK (Reuters) – Vodafone Group Plc could have the capacity to spend $30 billion to $40 billion on acquisitions in coming years and no deal should be too big if it makes strategic sense, Chief Executive Vittorio Colao said on Monday. Colao told reporters he was exploring possibilities for big acquisitions on top of investments in Vodafones existing business after a $130 billion windfall it will get from an asset sale to Verizon Communications later this month. We are looking at acquisitions that are sizeable and could transform the company, said the executive at a media roundtable in New York where he laid out his strategy for the worlds second-largest mobile operator. The theory is that if an acquisition makes sense you should not be worried by the size because shareholders should approve it, he added.
