Their pace of development is different, product portfolio also different, management skills and vision different.............so are we not likely to see (if sharing is implemented) antagonism as to the direction of infrastructure development (its pace, technologies wanted). Who will manage the infrastructure, is it all of them, are they going to have another company to do it. Is this going to lead to efficiency as envisaged or is it going to increase costs, bureaucracy and slowdown in infrastructure development. How will the change affect existing shareholders in terms of their return on equity, borrowings (debt) repayment plans and costs (may lead to company rating downgrades - etc). We need to distill whether this is a corporate decision or nationalistic - will it be voluntary or forced, all these questions cannot be satisfactorily be answered until we get all information. It will also be interesting to find how such proposals are being received by the operators themselves.
We also need to know what are the modalities of this sharing, will all the infrastructure pooled and sold to another company???? those in the know can help by explaining more
