Birmingham City Council has completed a£215m bond exchange deal to finance the refurbishment of its National Exhibition Centre.
Refinancing the bonds has released£40m cash up front to improve the NEC, plus£40m revenue savings over the next five years for the council.
The council's acting head of local planning Peter Wright said: 'The NEC brings to Birmingham and the wider West Midlands a market of activity that wouldn't be there if that fantastic facility wasn't there.'
Chairman of the NEC Group Roger Dickens said the refinancing would enable the business to compete internationally.
Council leader Mike Whitby (Con) said: 'The acceptance of this offer by investors demonstrates a continuing enthusiasm by the financial community to invest in Birmingham.'
Birmingham's finance manager Martin Easton said this refinancing of an existing debt was unusual, and was made possible by the prudential borrowing framework.
'Local authorities in the 1980s and 1990s financed a lot of developments off balance sheet. We are now bringing an off balance sheet liability on to the council's balance sheet.'
