I'm a little stuck... Click here to teach me more about this clue!

'charge?' is the definition.
(premium is a kind of charge)

I don't understand how the rest of the clue works.

(Other definitions for premium that I've seen before include "best quality" , "Extra cost of something in short supply" , "cash needed for cover charge" , "Great value - bonus" , "What may be paid" .)

I've seen this clue in The Hindu.
