'pending' not localised?

After applying my own translation I came accross 'pending' in the pull down select box in admin/store/transaction/create. When I created the pot files for the store module I did not come across 'pending', so I am wondering where I can find it in the code. When I go to admin/locale/string/search to search for it, it does not indicate a module and line number, it only says: /admin/store
