What Ramesh said that is correct.
I am going to give one example for Revenue Recognition
Contract Value - 100 Rupees
Planned Cost - 80 Rupees and Planned Revenue - 100 Rupees
Jan Month Cost - 20 Rupees.
Jan Month Revenue - 20 Rupees
POC = Actual Cost / Palnned Cost
POC = 20 / 80
POC = 25%
Actual Revenue is 20 Rupees. But As per the POC Method revenue should be 25 Rupees.
Difference Amount also we need consider as revenue (25 - 20 ) = 05.
So'We need to Recognition the Revenue as per the POC Method (100X25%)=25
