In my opinion, it depends on the stated accounting policy of your company regarding classification of refurbishing expense as capital expenditure or operating expense. It has less to do with the performance contract that you sign with the third party.
In terms of matching principle, you have to recognize expense in the year in which benefits are likely to accrue for such an expense. So, in the instant case you may not be able to calssify the entire refurbishing expense as operating expense for the year 2011.
