JPMorgan Chase & Co is arranging the 1-billion-euro ($1.34 billion) loan that SAP AG is taking on to help pay for its $3.4 billion takeover of SuccessFactors, SAP co-Chief Executive Bill McDermott told Reuters.

The 1 billion will probably be paid down within about a year. That's how we usually like to do it, McDermott said in an interview on Sunday, a day after announcing the takeover.

The deal, in which SAP is paying a premium of 52 percent over Friday's closing price of SuccessFactors shares, is a major push into cloud-computing services for the German business software company.

McDermott also said the deal could help the company beat its 2015 revenues target of 20 billion euros by as much as 1 billion.

We had cloud figured out in our 20 billion. We are now upping that 20 billion. It could easily go to 21 billion,

he said.
