Credit Suisse Group sold an office complex in Zurich to Norway’s $660 billion sovereign-wealth fund for $1.08 billion as the Swiss lender tries to boost its capital.

Norges Bank Investment Management acted as the buyer on behalf of the Norway Government Pension Fund Global, the Zurich- based bank said in a statement Thursday. The Uetlihof office complex is about 1.9 miles southwest of Zurich’s center, according to Credit Suisse.
