Trending @Cognizant; How much increment we can expect for this year appraisal

Bro from PA-> A my friend got around 12% He was from genc next so assume highest percentage will be 6

Even My question is when can it be expected ?

May be 3% for 3 ratings

TCS ia not giving anything this year, wipro also told they will check till year end and infosys give 2-4% to most of the employees. Now by looking at the trend you can calculate what cognizant will give.
