[1] | The Company incurred costs on Improvements comprising expenses for building interiors, electrical work, etc, which become an integral part of the building. These expenses are incurred to make the civil structure of the building ready for the intended use. These expenses on improvement are capitalized and depreciated over its estimated useful life of 5 years in accordance with the accounting policy consistently applied by the Company. The Company believes that it is more appropriate to disclose such improvements as a part of Buildings rather than as part of Furniture and Fittings. Hence the cost of such Improvements and the accumulated depreciation thereon, as on April 1, 2023 has been transferred as part of Building for a better presentation.
