Slim's America Movil might not face tough penalties if it doesn't sell assets

• If America Movil (NYSE:AMX) doesn't sell off assets -- as it said it planned to, to address competitive concerns -- it may not necessarily face tougher regulation after all, Mexico's chief telecom regulator says.
• The Federal Telecommunications Institute plans a March 2016 rule revision -- and after Mexico's congress passed telecom reform last summer to reduce the dominance of Carlos Slim's telecom giant, the company has planned asset sales to comply.
• But "The problem of the market is not the size of the operator; this is a market with economies of scale, it's capital intensive; the problem is having that power and abusing it," says IFT President Gabriel Contreras.
• AT&T and SoftBank were said to be looking at AMX's assets, which should draw more than $10B and maybe more than $15B in a sale.
