My mind is on 3 things at once here, so bear with me...
The government may be forced into a subsidy situation should the private sector not be willing to accept the type of risk being sold here and/or not be able to agree on a deal structure, which in this case would be incredibly complex. What are the alternatives? Government once again investing in the SPV and guaranteeing bond issuances? No, thank you. Private sector absorbing total risk in this market? How would one even structure such a deal? All you'd be doing is enriching the corporate ambulance chasers because inevitably you will end up with an overly convoluted structure.
Would you, as a fixed income investor, for example, invest in an entity of such a magnitude without vested interest from the lawmakers? In order to reduce risk, there needs to be some sort of intervention on government's part. Investment in the SPV would allay some investor concerns but it opens up its own hornet's nest that might just see history repeating itself. One cannot ignore the risk averse nature of the capital markets in this deal. Especially if a subsidy can guarantee cashflow for the bond market, who will inevitably be funding this. I don't see this coming from investment coffers from the private market.
But then again, telecoms is not my area of expertise. I just see it from the risk side and it doesn't appeal without government-sanctioned intervention of the non-investment type...
