No TP commission given on new commercial vehicle GCCV. only OD commission received. why? 

No TP commission given on new long term (both 3yrs for private cars and 5 yrs for two wheelers) policy. why?

OD commission received for 1 year only in New long term Package Policy (where OD premium paid by customer for 3rs in pvt car and 5yrs in two wheeler) then why we received commission for only 1 year?

there is no latest circular on the above mentioned matter. no information available in D.O

Can anyone clarify the above matters?
