FRANKFURT, May 11 (Reuters) - Around half of Thyssenkrupp's 5.7 billion euros ($6.27 billion) in pension liabilities are tied to the group's steel division, which is up for sale, the company's finance chief Klaus Keysberg told journalists on Thursday.
The size of steel-related pension liabilities, which have come down from 4 billion euros a few years ago, have been a hurdle to any deal to sell or hive off the business.
