following factors:
-application of smoothing mechanism under the
RAB procedure, which involves the removal of
economically viable revenue of the organization
in the current period and its recovery in
subsequent years;
- incomplete accounting of the fees for
reimbursement of costs of regulated
organizations in tariffs (service fee of JSC "FGC
UES", the cost of electricity losses).

20. Low liquidity of the Company's ordinary shares
A large proportion of income from technological connection,
which investors prefer to null in the forecasts due to its
instability
The unfair dividend policy, entailing redistribution of value
from holders of ordinary shares to holders of preferred
shares
A low investor interest in the distribution grid complex due
to the uncertainty regarding the tariff regulation and
prospects for RAB
Concerns and comments
To build a financial model of the Company for a five-year period it is necessary to
wait for a policy decision of regulators regarding the rates of growth and the future
of RAB-regulation
Following the implementation of the additional issues of ordinary shares in 2011-
2013 by public subscription, the amount of shares in free float will increase, thus
resulting in the increase of securities' liquidity
In accordance with the approved Business plan of the Company for 2011-2015, the
share of revenue from the services of technological connection is reduced, reaching
9% in 2015 (in 2011 the plan is 22%). It is assumed that starting from 2014, profit
from electricity transmission services will be positive
Feasibility of financing the Investment program by the funds
received from the additional issues of ordinary shares
Funds received from the additional issues of ordinary shares in 2011-2013 will be
directed to the implementation of the target program – renovation of the cable
network in St.-Petersburg. The program is federal in nature, therefore for its
implementation the funds are sent from the federal budget (through the
participation of JSC"IDGC Holding"), as well as the funds of the city budget (through
participation of the CPMC, SPb). Funding for the target program is carried out by
means of additional shares as a direct budget subsidies for a JSC is impossible
Factors, limiting the investment demand Comment of the management of JSC "Lenenergo"
| 17
Key factors to address this issue is the approval by the Russian government of the
strategy of JSC "IDGC Holding" and the distribution-grid complex of Russia, as well as
achieving by the Company a sufficient level of profits for distribution between
shareholders. The Company is planning to decide the issue of the existing imbalance
in the dividend policy while respecting the legitimate rights of all shareholders
