'It was pointed out to us that the uncertainty of the assessment of the value (of our UK property portfolio) by external assessors has increased,' deputy chief executive Trond Grande told a news conference.

At the end of July, Norges Bank RE Management purchased an asset from Aberdeen Asset Management in the UK, buying the long leasehold interest in 355-361 Oxford Street in an all-equity deal worth £124 mln (€148 mln).

355 Oxford Street, a 5,500 m2 retail and office building, has a long leasehold from the City of London Corporation with an 139-year unexpired term. The asset is mainly let to Boots, which occupies 2,926 m2 of retail space and 1,347 m2 of offices.

It also owns a 50% stake in the Meadowhall shopping centre in Sheffield, a share of Regent Street and is also invested in the Pollen Estate. Currently about 25% of the fund's real estate holdings are in the UK, with 16% in London.

Norway's state wealth fund, Government Pension Fund Global, which has a market value of NOK 7297 bn (€669 bn) is the largest sovereign wealth fund in the world and is currently invested in 78 countries, which cannot include Norway. 3.1% of the fund is in real estate, as of 30 June 2016.
