The company name will be accompanied by CP alongwith date/year of maturity as a part of the standard descriptor. This will enable both Investors and the Depository Participants to easily identify these instruments. e.g. RIL 90D CP 10NV00 indicates 90 day (duration of the paper) CP issued by Reliance Industries with maturity date as November 10, 2000.
If the CP is allotted on different days say for 89 days to one investor, 88 days for another investor, the number of days in the descriptor will indicate the number of days the Issuer has provided NSDL at the time of the activation of the ISIN. Also, if the CP has been provided a backstop facility then the descriptor changes to RIL 90D CP 10NV00-BS.
