The Dutch Finance Ministry expects the European Union's Commission to extend temporary approval for a EUR22 billion guarantee on ING Group NV's (ING) Alt-A mortgage securities.

"We are still in constructive talks with the (commission) and we expect them to extend the temporary approval for the deal later Tuesday," a spokeperson for the Finance Ministry said. She added the talks take longer because of the complex nature of the deal.

In January, ING announced an agreement with the Dutch government on an Illiquid Assets Back-up Facility covering 80% of ING's Alt-A mortgage securities. ING will remain the legal owner of 100% of the securities and will remain exposed to 20% of any results on the portfolio.

The European Commission earlier said it will make a statement on the Dutch government's state aid to troubled bancassurer ING later in the day. "There will be a statement later today," said the commission's competition spokesman Jonathan Todd.
