Lone Star Global Acquisitions Ltd. is handing over to lenders the remaining assets in a U.K. shopping center portfolio that it acquired from Rockspring in 2014 for £260 million using a £200 million loan from Citi, Property Week reported.

Austrian lender BAWAG Group AG, which provided the senior mezzanine loan for the acquisition of the portfolio, is set to receive the properties, including the Mercury Mall in Romford and Marlands in Southampton in the U.K., according to the publication, citing Debtwire. The debt market intelligence platform also mentioned Citi and Oz Real Estate as the other lenders.

The shopping centers are being surrendered amid the declining values of retail properties, the March 12 report added. The U.S.-based private equity firm has been selling the retail portfolio, codenamed Project Tiger, in the past year and was able to find buyers for the Grays and Blaydon shopping centers in Essex and Newcastle, respectively. However, divestment of the other properties was unsuccessful.

The sales process for the remaining assets in the portfolio is still ongoing, the publication added.
