The telecoms group is trying to raise funds to reduce a 57billion euro debt pile and preserve a coveted investment gradecredit rating, at a time when its crisis-hit home country facespressure to seek an international bailout.

The deal includes a 110-million-euro deferred payment byBain, which was co-founded by U.S. Republican presidentialcandidate Mitt Romney, as well as 110 million euros in financingprovided by Telefonica, the Spanish group said on Friday.

Telefonica has been looking for a buyer of Spanish-basedAtento ever since it shelved a stock market listing of the unit,which has over 152,000 employees, last year after failing tofetch enough interest.

Telefonica expects to close the Atento sale, which issubject to regulatory approval, before the end of the year. Thedeal also includes a nine-year agreement for the call centre tocontinue providing services to Telefonica.

Atento had 1.8 billion euros in 2011 revenue. It is theleading customer relationship management company in LatinAmerica and the second largest in the world, according toTelefonica.
