Finished plans for lending arrangements (10)

I believe the answer is:

overdrafts

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

'lending arrangements' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.

'finished plans' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'plans' becomes 'drafts' (drafting is a kind of planning).
'over'+'drafts'='OVERDRAFTS'

'for' is the link.

Can you help me to learn more?
