 notified for the purpose of recovery of tariff, by CERC.
 
 MoP has issued tariff policy which provides that rates of depreciation
 notified by CERC would be applicable for the purpose of tariff as well
 as accounting.
 
 In accordance with the Tariff Policy, CERC has notified norms for the
 block period 2009-14 which provides for specified depreciation rates in
 first 12 years and thereafter amortisation of residual value over the
 residual life. Accordingly, depreciation on the transmission assets for
 the year has been provided as per rates and methodology notified under
 CERC Regulations.  b) Depreciation charge for the year is lower by
 Rs.64.82 crore (previous year Rs.50.69 crore) as compared to the
 depreciation as per rates provided in the Schedule XIv of the Companies
 Act, 1956.
 
 12. Effects due to changes in accounting policies during the year
 
 a) In view of an opinion of the expert advisory committee (EAC) of the
 Institute of Chartered Accountants of India, capital expenditure on
 assets not owned by the company, which was hitherto amortized over a
 period of four years, is now charged off to revenue as and when
 incurred. The unamortized balance as on 01/04/2010 under Fixed Assets
 and CwIP Schedule has been written off as prior period expenditure.
 This has resulted in decrease in profit by Rs.3.56 crore (including prior
 period impact of Rs.4.22 crore) with corresponding decrease in CwIP/Fixed
 Asset. The matter has been referred to EAC for reconsideration.
 
 b) Leasehold land, which was hitherto depreciated over the tenure of
 the lease, is now depreciated in 25 years or tenure of the lease
 whichever is less in accordance with the rate and methodology specified
 in CERC (Terms & Conditions of Tariff) Regulations, 2009 with
 retrospective effect from 01/04/2009. This has resulted in decrease in
 profit by Rs.5.21 Crore (including prior period impact of Rs.2.10 Crore).
 
 c) Liabilities for price variation/ exchange rate variation in case of
 contracts which were hitherto accounted for on acceptance/receipt of
 claims are now being accounted for on estimated basis as per terms of
 the contracts. The above change has resulted in increase in liability
 by Rs.191.26 Crore with corresponding increase in CwIP/Fixed Assets. The
 above has also resulted in decrease in Profit by Rs.10.49 crore.
 
 d) Liquidated damages / warranty claims which were hitherto being
 accounted for on receipt / certainty of receipt, are now recognized
 when no significant uncertainty as to measurability and collectability
 exists. The above has resulted in Decrease in liability by Rs.59.70 crore
 with corresponding decrease in CwIP/Fixed Assets. The above has also
 resulted in decrease in Profit by Rs.2.98 Crore.
 
 e) CERC Tariff Regulations 2009 for block period 2009-14 provide that
 tariff for additional capital expenditure incurred after the date of
 commercial operation shall be allowed based on the projected
 expenditure. In view of the above, Transmission income in respect of
 additional capitalization, which was hitherto accounted for on the
 basis of specific order by the CERC, is now being accounted for on
 accrual basis based on actual expenditure incurred from year to year
 after date of commercial operation. This has resulted in increase in
 transmission income amounting to Rs.57.17 crore (including Rs.17.47 crore
 for financial year 2009-10).
 
 f) The expenditure on Corporate Social Responsibility (CSR) which was,
 hitherto, incurred / appropriated out of profit to the extent of 0.75%
 of net profit of the preceding financial year, is now being incurred /
 appropriated to the extent of 1.00% of such profit. This has resulted
 in additional expenditure/appropriation of Rs.5.10 crore for the year.
 
 g) Surcharge, which was, hitherto, accounted for on receipt / certainty
 of receipt, is now being accounted for when no significant uncertainty
 as to measurability and collectability exists. The above change has
 resulted in increase in profit due to accounting of additional
 surcharge of Rs.5.14 crore for the year.

 a) The Company has billed and recognized transmission income as per
 tariff orders issued by CERC applicable for the block period 2009-14.

 notification dated 02.05.2011 to the effect that Commission may

 annual fixed cost of the project claimed in the application subject to
 adjustment after the final tariff order has been issued.
