*Level of weather resistance refers to the percentage of medium-voltage network which either has been cabled or is located in an environment where trees do not compromise electricity distribution.
**The investment figure for 2017 is not completely comparable to earlier years due to different calculation methods.

*Safety walks carried out by Caruna’s employees on worksites and offices. The results for 2016 and 2017 are not comparable with those for 2015 because Caruna outsourced project supervision in August 2015 and since then the Safety Walks carried out by the project supervision have been reported as site inspections.
**The TRIF (Total Recordable Injury Frequency) reflects the ratio of occupational accidents to Caruna’s employees, leading to absences from work or requiring medical treatment visits, in relation to working hours (incidents/million realised working hours).
***The LWIF (Lost Workday Injury Frequency) reflects the ratio of work-related injuries to contractors or subcontractors, including trainees and temporary workers, while they work for Caruna or are within Caruna’s work sites, leading to a disability of at least one working day, in relation to working hours (incidents/million realised working hours).
****An injury leading to a disability of over 30 days or a permanent disability.

 

No occupational diseases were diagnosed among Caruna’s employees in 2017.
