7 Petroleum and alcohol accounts - STN
In order to settle accounts with the Federal Government pursuant to Provisional Measure 2181, of August 24, 2001, after providing all the information required by the National Treasury Department (STN), Petrobras is seeking to settle the remaining differences between the parties.
At September 30, 2009, the balance of the account was R$ 816.714 thousand (R$ 815.172 thousand at June 30, 2009) and this can be settled up by the Federal Government by issuing National Treasury Notes in an amount equal to the final balance for the settling of accounts or through offsetting against other amounts that Petrobras may be owing the Federal Government at the time, including tax related amounts or a combination of the foregoing operations.
