As the index obtained in 2023 is higher than 85 points, the Company is not obliged to set and publish targets for the progression of each of the indicators of the Index, nor is it obliged to publish, through external communication and within the company, the measures for correction. This score, which is in line with expectations, is the result of the measures implemented by GTT to maintain internal equity, in particular by monitoring the indicators of the gender equality agreement.
