Taxation
   
   
  Current
  Charge for current taxation in the accounts is based on the higher of taxable income at the current rates of taxation or half percent of turnover.
   
   
  Deferred
 

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax base of assets and liabilities and their carrying amounts in the financial statements.

From the current year the company has recognised a deferred tax debit balance in these financial tatements by following IAS 12 - " Income Taxes (revised 2000)"
.

Upto the previous year the company accounted for deferred taxation using the liability method on all significant timing differences but did not account for any deferred tax debit balance. The change in accounting policy is made on adoption of IAS-12 (Revised) that is applicable from the current year. Had the policy not been changed the profit after taxation would have been lower by Rs. 31.5 million. The adjustment arising due to change in accounting policy has been accounted for in the current year profit and loss account. The comparative information has not been restated due to the applicability of pricing formula as explained in accounting policy 2.11 (c) below.
.

   
  Fixed assets and depreciation
  Fixed assets are stated at cost less accumulated depreciation except capital work-in-progress which is stated at cost. Depreciation is charged to income by applying the straight line method whereby the cost of an asset is written off over its estimated service life to the Company.

The formula was further amended, effective July 1, 2002, for certain refineries including the company. Under this tariff protection formula the concerned refineries have been allowed to charge a deemed duty on some of their products enabling them to run their operations on a self-financing basis.
