Cognizant, which has a majority of its workforce in India, had a heacount of 2,56,800 people in the June quarter. This number stood at 2,61,200 employees at the end of March, 2017.
"Our attrition level was higher than normal given reductions resulting from performance evaluations and the voluntary separation programme," Cognizant CFO Karen McLoughlin said on an earnings call.
The annualised attrition rate stood at 23.6 per cent, including BPO and trainees, during the June quarter.
In May this year, Cognizant extended a "voluntary separation incentive" to some of its top-level executives, offering them up to nine months of salary.
