RESTRICTED CASH
We include in restricted cash on our consolidated balance sheets amounts representing a cash account for which the use of funds is restricted by a facilities connection agreement among us and Gibson Energy Partnership, or Gibson, that we entered into during 2014 in connection with the development of our Hardisty terminal. The collaborative arrangement is further discussed in Note 11. Collaborative Arrangement. As of December 31, 2015 and 2014, we had restricted cash balances of $4.6 million and $6.5 million, respectively, for undistributed amounts retained in our joint revenue collection bank account.
