HELSINKI – Nokia Corp. plans to streamline operations, as its first-quarter net profit dove 90% and sales fell 27%. As part of the cost-saving measures, the company will cut up to 450 jobs worldwide. 

In March, the company announced plans to eliminate 1,700 positions in the devices and markets units, corporate development office and global support functions. It will also lay off 320 workers and temporarily lay off 2,500 workers when it closes a research center in Finland.

The company’s goal is to reduce annual costs of its handset unit by $920 million, and some mobile services will be outsourced. The measures are part of a previously announced plan for adjusting operations and costs.
