Unilever is set to buy Finnish firm Ingman Ice Cream for an undisclosed sum.

Ingman Ice Cream has production facilities in Finland, Sweden, Lithuania and Belarus. In 2010, the company's brands generated annual sales of EUR70m (US$96.3m).

A spokesperson for Unilever said: "The Ingman brands enjoy strong consumer recognition, offer significant growth potential and have an excellent fit with our existing business."

He added: "Ice cream is a strategic category and a key growth driver for Unilever."

The acquisition is subject to regulatory approval but Unilever expects it to be complete at the beginning of 2012.

Ice cream is the remaining food interests of family-run investment company Ingman Group. The family sold its wider dairy operations in 2008 to Arla Foods.
