The unrecognised tax losses expire within eight years from the reporting date.
The aggregate amount of temporary differences associated with investment in subsidiaries at the reporting date is RUB 32,347 million (31 December 2011: RUB 18,970 million). The deferred tax liability for these temporary differences has not been recognised because the Parent can control the timing of reversal of the temporary difference and it is probable that temporary differences will not reverse in the foreseeable future.
The unrecognised temporary differences relating to investments in associates at the reporting date is RUB 5,167 million (31 December 2011: RUB 5,234 million).
