Danske Bank has said it expects to write down around 9 billion Danish crowns ($1.5 billion) of the value of its businesses in Finland, Northern Ireland and Estonia.
Denmark's largest bank by market capitalisation has had to cut staff and branches to recover from the financial crisis.
It has been hit hard by its exposure to Ireland and weakness in Finland, which has been weighed down by Europe's standoff with Russia.
The writedown follows a stress-test by the Danish Financial Services Authority conducted alongside the European-wide checks.
"The goodwill impairments are of a purely technical nature and do not affect our strategy or business. The impairments also will not affect our regulatory capital or liquidity," Danske's chief financial officer Henrik Ramlau-Hansen said in a statement.
The bank confirmed its guidance for a 2014 full-year net profit of between 11.5 billion and 13.5 billion crowns - excluding the write down.
The goodwill impairment will not affect Danske Bank's plan to pay a dividend of 40% of net profit for the year, it added.
