Signatures and link to series

I have a 20 dirham 1996 series note. The signatures are the same as for the next series. Am I correct to say it is one of the last ones in the 1996 series? How do I classify it when recording it?

Classifying your note has nothing to do with the issue date (1996) but the various signature versions. 

Compare your note's signatures with the ones shown on this BNM site (it should help you input yours in the correct P67a to e slot). Numista hasn't gotten around to photoshopping & identifying the various signature variations.
