Auditors cite a limited share (5)
I believe the answer is:
quota
'share' is the definition.
(I know that quota is a type of allocation)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for quota that I've seen before include "Designated amount" , "Regulated number" , "Proportional share" , "Share, allowance" , "certain allowance" .)
