The decision was outlined in an interview with production chief Michael Schiebe and labour director Britta Seeger published on the company's intranet Thursday, according to the newspaper.

Schiebe said the board jointly decided to suspend further investment because current cost structures prevented the company from investing in Germany, and intensive discussions had failed to produce a path toward agreement.
