 accepted accounting principles requires estimates and assumptions to be
 made that affect the reported amounts of assets and liabilities and

 reporting year.  Differences between actual results and estimates are
 recognised in the periods in which the results are known/materialise.
 
 (c) Fixed Assets
 
 Fixed assets are stated at their historical cost of acquisition or
 construction, less accumulated depreciation/amortization and impairment
 loss. Cost includes all costs incurred to bring the assets to their
 working condition and location (Also refer note 25) and Site
 Restoration cost obligations where outflow of resources is considered
 probable.
