Shortens more than one agreement (9)

I believe the answer is:

contracts

I believe this is a double definition.

'shortens' is the first definition.
('contract' can be a synonym of 'shorten')

'more than one agreement' is the second definition.
(contract is a kind of agreement)

(Another definition for contracts that I've seen is " Legal agreements".)

I've seen this clue in The Times.
