tax exemption on settlement amount after job loss

I lost my job in November (company asked me to resign immediately) and was given a lump-sum amount as settlement amount (2 months salary,i.e dec & jan, but my job terminated in nov) in April (next financial year). I want to know whether I have to add this settlement amount as income in next financial year or there is some clause in income tax rule for getting tax exemption on this amount. After termination I was jobless for almost 11 months.
