At December 31, 2017, legal claims mainly comprise provisions for labor liabilities and tax claims for S/19.3 million (S/14.7 million at December 31, 2016). Claims with the tax authority have been accounted for based on management estimates of the amounts the Group would most likely be required to pay in regard of these current court actions. Due to the fact those amounts will depend on the tax authority, the Group does not have an estimated timing of when these cash outflows would be required.

This legal claim balance also includes court actions brought against the Group by the Peruvian energy regulator (OSINERGMIN) resulting from the storage of hydrocarbons and the applicable environmental laws and regulations for S/5.1 million (S/6.3 million at December 31, 2016).

The gross movement of other provisions is broken down as follows:
