At start of year Fair value gain/(loss) Disposal Investment properties relate to three pieces of leasehold land (5,367 acres) held by the Group under long-term lease arrangements and a freehold parcel in Kikambala. The fair value of the investment property is based on the valuation carried out by Regent Valuers International (K) Limited independent valuers, on the basis of open market value (Level 3) as adjusted for the estimated cost of eviction of squatters as explained below. The valuer is a registered valuer and has recent experience in the location and the category of the investment property being valued. The Group assets have been charged to secure loan facilities as disclosed in Note 23. Approximately 40% of the investment properties are currently occupied by squatters. The Company continues to pursue several avenues to reclaim the occupied properties. The estimated costs of evicting squatters amounting to Shs 376,904,000 has been adjusted in arriving at the fair value of investment properties. Management has used significant judgement and assumptions in determining the appropriateness of classification of the encroached land as investment property and in arriving at the cost of evicting squatters. Given the subjective nature of the estimates it is possible that outcomes that are different from the assumption could require a material adjustment to the carrying amount of the asset. The main estimates and assumptions related to: - the period required to evict the squatters; - security resources required and their cost; - legal costs. Despite the encroachment, the Directors believe that the land occupied by squatters has an economic value to the Group based on the offers already received for it and a commitment from the Government to facilitate eviction as necessary. It is therefore appropriate to continue classifying the land as investmen property
