Fiber infrastructure and colocation provider Zayo Group LLC plans to issue a $650 million term loan and $800 million in senior unsecured notes to fund the $1.42 billion acquisition of Electric Lightwave Inc. (formerly Integra). We are raising the corporate credit rating on Zayo to 'B+' from 'B' and removing all ratings from CreditWatch. We are assigning our 'BB' issue-level rating and '1' recovery rating to the company's proposed $650 million term loan and our 'B' issue-level rating and '5' recovery rating to its proposed $800 million senior unsecured notes. The stable outlook reflects our expectation that the company's high leverage and aggressive expansion policies will be balanced by the company's good growth prospects. On Jan. 6, 2017, S&P Global
