Description of nature of entity's relationship with associate | The Group held one associate investment at 31 December 2022 which had a material impact on profit for the year, a 19.9% interest in 111 East 48th Street Holdings, LLC (the ‘Barclay associate’) which owns InterContinental New York Barclay, a hotel managed by the Group. The investment is classified as an associate and equity accounted. While the Group has the ability to exercise significant influence through certain decision rights, approval rights relating to the hotel’s operating and capital budgets rest solely with the 80.1% majority member. The Group’s ability to receive cash dividends is dependent on the hotel generating sufficient income to satisfy specified owner returns. $18m was provided in 2021 in relation to settlement of a commercial dispute regarding owner returns during the pandemic. |  |  |  |
