Nokia on Thursday finalized the layoffs of 1,000 employees, which will be implemented throughout 2012, according to a reportfrom Reuters.

The jobs will be mainly culled from a manufacturing plant in Western Europe.

The remaining staff at the plant will focus on tailoring models for European operators.

The layoffs are part of a complete overhaul orchestrated by CEO Stephen Elop. Under Elop, Nokia has reorganized its smartphone business around Microsoft Windows Phone mobile operating system.

The company has had a rough year so far. Earlier this month, the S&P downgraded Nokia’s long-term credit rating to BBB, dropping the smartphone maker to the lowest investment grade rating.
