  1. Formation of Interregional Distribution Grid Company JSC IDGC of the Center December 20,2007

  2. Strategy of cost evaluation of IDGC/DGC and main proposals

  3. Evaluation Strategy Date of evaluation – June 30, 2007 . Termination of prognostic period – 2015 DCF 100 % Switch during 2010-2012 to RAB regulation Main proposals - - - Restriction of transfer tariff growth in 2010-2014 Payment for connection is taken into account in proceeds, capital - , investments but is not considered in the capital base , Calculation is based on the net asset method . Expense approach 0 % Market value RCN (full replacement cost) = t Physical depreciation – External depreciation – External depreciation is defined as correlation between the existing capital investments and the required ones. Expense approach was not used because it is impossible to define the amount of external Depreciation during absence of the technical audit and detailed information ( load, transfer volume, etc) on each center of the distribution grid. , . Comparative approach Method of similar companies was not applied because the selected companies that render services on Transfer of electric energy do not possess characteristics necessary for applying the comparative approach – there is considerable difference in the scale, maturity, level of diversity and organisation models of their business. The transition method was not applied because the data on Purchase contracts of distribution grid assets is absent due to the business monopoly. - , 0 % – .

  4. Main propositions of DCF evaluation Macroeconomic indicators Deloitte Regulation RAB regulation Expenses + Transition period Fixed assets 1H2007 (re-estimated according to Russian Accounting Standards) + investments (without payment for Connection) + circulating capital Capital base Electric energy Business plans of DGC Growth rates included (Deloitte)* supply Volume of losses Business plans of DGC By 2015 is to enter the target level г Payment of losses Business plans of DGC According to day-ahead prices (Deloitte) Operational expenses Business plans of DGC - Inflation growth rate included Capital investments At the amortization level of the previous year Business plans of DGC - Restriction of Tariff growth Business plans of DGC - At inflation growth rate of + 4%** 2 H 2007 2008 2009 2010 201 1 2011 2012 2013 2014 2015 * * Plan of organic growth** On the basis of average historical exceeding of the tariff growth over inflation.

  5. Profit of the capital base Capital basex WACC (regulatory) = + + Return on the capital base Necessary gross returnby RAB method Operational expenses Calculation of tariffs according to the method of the investment capital profitability (RAB) It is supposed that from 2010 to 2012 Expenses+ strategy of tariff regulation on transfer of e/energy through distribution grids will be replaced by the method of profitability of the invested capital ( RAB –return on Regulatory Asset Base). The essence of RAB strategy is guarantee of full return of the means invested into the assets of the company during the fixed period that corresponds to the terms of validity of the assets and reception of the stable income the level of which is defined by the regulator that must conform to the risk profile of DGC and guarantee attractiveness of the branch for the investors. Operational expenses include all the field costs of the company except for amortization of the fixed assets, intangible assets. Return on the capital base must guarantee reproduction of the assets that are effectively used at transfer of electric energy through DGC’s grids. Profit of the capital baseis defined by the norm of profitability (regulatory WACC) fixed by the regulator the stake of which will be fixed for the long-term period of regulation equal to all DGC.

  6. Calculation of the capital base for tariff calculation by RAB method For the purpose of correct prognosis of indicators of the operational activity of the distribution grid companies after switch to the system of regulation of their tariffs on the basis of RAB method, calculation of the regulator capital base for the moment of the planned introduction of new rules of tariff design (beginning of 2010) was realised. Regulatory capital base (as of the beginning of 2010) + Cost of capital investments for 2H2007-2009. + = Circulating capital as of the beginning of 2010 Initial capital as of the beginning of 2010 Investments on the level of amortization of the previous year - + + = Change of the circulating capital Regulatory capital base of the previous year Regulatory capital base Amortization The initial capital is defined as the cost of the fixed assets that are on the balance of the company as of June 30,2007 and that were re-estimated according to Russian Accounting Standardsfor the end of 2009. Capital investments for 2H2007-2009from business plans of the companies Circulating capitalis defined on the basis of the existing circulation factors and their correspondence to average branch indicators during the accounting period. In the following years of the regulation period the regulatory capital base is calculated by the following way:

  7. Calculation of the capital base for tariff calculation by RAB method • The initial capital used for defining of the regulatory capital baseas ofthe beginning of 2010is defined as the full cost of asset replacement with regard of their physical depreciation: • The initial capital is defined proceeding from the current legislation concerning estimation of cost of the fixed assets for the purpose of book keeping • Only the industrial assets are included into initial base of the invested capital (OL, substations, transformer substations), non-profile assets are not considered at calculation of the capital base • The investments that were realised at the expense of payment for technical connection are not included into the capital base in order to avoid double calculation. • Full cost of replacement is defined as cost of production or construction under the current conditions of the similar new object that by its functional characteristics is as much as possible similar to the estimated object. • Physical depreciation is price decrease due to depreciation, dilapidation and aging, and also deterioration of properties that cannot be eliminated at the expense of the current service.

  8. Calculation of WACC rates Cost of the owned capital Risk-free rate (nominal) 5.21% Market premium 5.50% Beta (unlevered) 0.87 Corrected Beta ratio 0.60 Country risk 0.01 Specific risk for the reformation period 0.00% Final cost of the owned capital of the company 10.95% Premium for small-cap 2.28% – 6.27% Debt capital cost Cost of debt funds (before taxation) 10.32% Tax profit rate 24.00% Cost of debt funds (after taxation) 7.84% Structure of the capital Target correspondence of debt to owned capital 61.00% WACC for discounting 11.18% – 13.67% Regulatory WACC before taxation 9.78% Regulatory WACC after taxation 12.86% Discount rate and regulatory norm of profitability
