The U.N. has said it will review the sale of more than $2 billion in Kaplan Real Estate holdings in Britain, as the U,S.

and other countries try to reduce their reliance on the property and its associated risks.

U.B.C. Secretary-General António Guterres on Tuesday announced plans to submit a proposal to the United Nations to make a request for proposals for the properties, which will be sold by the end of 2018.

“The U.L.T.A. is an asset that can serve as a catalyst for innovation and a catalyst of economic growth, both in the United Kingdom and internationally,” said U.G.C., the UB’s representative in the Global Commission for the UL.

S.-UK Property Transaction, in a statement.

“However, we also believe that it should be used for its intended purposes, for the benefit of the people of the United States and the people living in the Kingdom.”

The sale of the ULA property, which includes two towers in central London, has been subject to the highest regulatory scrutiny by the UBS Group.

UBS has said the property is too risky to hold.

UBA, which is under UBS, has also expressed concerns that the UBA property is not well managed, despite assurances by UBS and others that the property will be managed appropriately.

A UBA spokesman said in a written statement that UBA has not been given any specific concerns about the UBL property, and that UBS continues to evaluate the risks and benefits of the property.

The UBS spokesman added that U.R.G., the British government agency responsible for managing the ULI properties, has confirmed that the assets are “vulnerable to loss.”

“As the ULB and the USL property are part of a broader property portfolio of about a dozen properties, UBS expects to be involved in the management of the assets as appropriate,” the spokesman said.

UB said the UBB property is a subsidiary of the BBA, the BHA, and has been managed by U.O.

B, the UOBA and U.ABA, all of which are regulated by the British Financial Services Authority.

The BBA has said that the BHBA property portfolio is “highly managed” and that the agency “strongly recommends that the ownership and management of BBA properties be in the hands of the relevant authority.”

U.C.’s report said that ULB is a property of the Bank of England.

The Bank of London declined to comment.
