Ja tam widzę wyraźnie "on".
Tak samo tutaj:
http://www.dictionary.com/browse/loan
a. borrowed for temporary use:
How many books can I have
on loan from the library at one time?
b. temporarily provided or released by one's regular employer, superior, or owner for use by another:
Our best actor is
on loan to another movie studio for two films.
Czyli z "on" to jest po prostu pożyczka, którą
ja zaciągam?
