Paragraphs:
Financial review
2019 was a challenging year for the retail property sector with the ongoing structural changes and low consumer confidence impacting some weaker retailers and leading to a higher level of CVAs and administrations. This impacted our revenue, net rental income and property valuations, with like-for-like net rental income down 9.1 per cent and the property revaluation deficit was £1,979.7 million.
Fixing the balance sheet is our top strategic priority and although the notes accompanying these financial statements indicate a material uncertainty in relation to intu’s ability to continue as a going concern we have options including alternative capital structures and further disposals to put us on a stronger financial footing.
1 A reconciliation from the IFRS consolidated income statement to the underlying earnings amounts presented above is provided in presentation of information on page 161.
2 Other underlying amounts includes net other income, share of underlying profit in associates and any underlying amounts attributable to non-controlling interests.
3 Other non-underlying amounts includes losses on disposal of subsidiaries, gains on sale of investment and development property, write-down on recognition of joint ventures and other assets classified as held for sale, impairment of goodwill, impairment of investment in associates, impairment of loan to associate, exceptional administration expenses, exceptional tax, and any non-underlying amounts attributable to non-controlling interests.
The IFRS loss for the year attributable to owners of intu properties plc increased by £818.7 million to £1,950.9 million, with the IFRS basic loss per share increasing by 60.8 pence. Underlying earnings decreased by £65.9 million to £127.2 million, with a corresponding reduction in underlying EPS of 4.9 pence. The key drivers of these variances are discussed below.
