9. Cost of Operating Expenses
2Q09/2Q08 main changes:
The increase in personnel expenses in 2Q09 against the same period in 2008 is due to the annual wage
bargain agreement of 6.8% in June 2008, the increase in CESP Foundation expenses and the lower income
expected from the retirement plans (CVM Decision 371);
The increase in third party IT services and outsourced transmission line maintenance;
In 2Q09, expenses relating to allowances for contingencies fell by 75.8% as compared with 2Q08;
The positive value for expenditures with materials in 2Q09 is due to a reclassification for permanent
assets in progress of a expense of R$ 2,357 thousand booked in 1Q09.
