I think that the expense of 3.1. is the same as "2014 Fee" of 3.3..
Therefore, I defined the expense of 3.1. as "2014 Fee".
In the contents of 3.5., I understood that
the payment of 2014 Fee becomes the amount of money depending on the days until December 31 since we made a contract.
Therefore, I added a postscript to understand so.
