Finance written down internally (5)

I believe the answer is:

endow

'finance' is the definition.
(I've seen this in another clue)

'written down internally' is the wordplay.
'internally' says the answer is hidden in the clue.
'ENDOW' is hidden within 'written down'.

(Other definitions for endow that I've seen before include "Woden (anag.)" , "Provide capital to ensure an income for an institution" , "Give permanent income to" , "Attribute abilities to" , "Bequeath estate to" .)

I've seen this clue in The Independent.
