According to Xinhua newspaper, Spain will take formal offers from potential buyers for Spain's nationalized lender Novagalicia Banco from Tuesday.

Local media reported on Tuesday that those potential buyers, which have already shown their interest in buying the bank, are Spanish banks Santander, BBVA and Caixabank, and Venezuela's Banesco.

Meanwhile, the funds of investments Guggenheim, WL Ross, J.C. Flowers and Anchorage are also interested in buying Novagalicia Banco.

Novagalicia Banco is based on the northwestern region of Galicia and its EVO Banco unit that operated outside the region has already been sold to the U.S. firm Apollo Global Management in September.

The Spanish Minister of Economy Luis de Guindos said in an interview on Monday that "in three or four weeks" Novagalicia Banco would be sold. However, the sale of Catalunya Banc (also nationalized) has been delayed after two failed attempts.

Asked about how much money Spain will end up losing after the bailout, de Guindos said it remained unknown as the largest nationalized entity, Bankia, would not be privatized yet.

Novagalicia Banco received 5.425 billion euros (7.338 billion U.S. dollars) from the European Union's bailout in December 2012, after Spain had injected 3.627 billion euros into the lender.

It reported 61 million euros of net profit from January to September as opposed to the losses of more than 7.9 billion euros the entity registered in 2012.
