Pair delivered speech, appropriately shared (8)

I believe the answer is:

prorated

'appropriately shared' is the definition.
(to prorate is to share proportionally or pro rata)

'pair delivered speech' is the wordplay.
'pair' becomes 'pr'.
'delivered speech' becomes 'orated'.
'pr'+'orated'='PRORATED'

(Another definition for prorated that I've seen is " Allocated in proportion".)

I've seen this clue in The Guardian.
