(REUTERS) -- Greece's private sector creditors could take a loss of more than 70 percent in a planned debt swap, Finance Minister Evangelos Venizelos said on Tuesday.

There is a very serious discussion based on new facts. We are talking about a PSI much greater than the original, he told lawmakers, referring to private sector involvement in the deal.

We are talking about a haircut on the net present value exceeding 70 percent, he said.
