Contractors costs include expenses related to contractor staff not on the Company’s payroll. The increase in contractors’ costs compared with previous year reflects the general ramp-up of Turnkey activities and the Company’s strategy aiming to maintain flexibility in its workforce monitoring. Other employee benefits mainly include commuting, training, expatriate and other non-wage compensation costs.
