French cable operator Numericable Group SA will on Wednesday raise almost EUR8 billion ($11 billion) in the biggest junk-bond sale on record.

Bankers say the company will pay investors yields ranging from 4.875% to 6.25% for the various chunks of bonds on offer, which are split between euros and dollars. That is a slightly lower price tag for the borrower than expected, with initial talk suggesting yields ranging from about 5% to a little more than 6.5%.

At the same time, Numericable's parent company Altice SA will raise an equivalent of EUR4.15 billion from an eight-year dual-currency bond, yielding 7.25% in euros and 7.75% in dollars.

That takes the combined financing package, which includes EUR1.9 billion of Numericable loans, to almost EUR14 billion. The cash is being used to help fund Altice's EUR17 billion acquisition of Vivendi SA's telecoms business SFR.

The Numericable bond is expected to be rated Ba3 by Moody's Investors Service, three notches below investment grade. The Altice bond is expected to be rated B by Standard & Poor's Corp., five levels into junk territory.

Deutsche Bank AG, Goldman Sachs Group Inc. and J.P. Morgan Chase are coordinating the bond sales.
