What do the designations PRN, CALL and PUT mean?
These are to segregate holdings by class. PRN indicates principal amount on convertible debt securities. If the holdings being reported are put or call options, then the designation "PUT" or "CALL" is used as appropriate.

I still don't understand PRN? Can someone explain what the 12 m shares are that Orbimed has,that has PRN after it?
