At the payment date, the present value of the IRU finance lease liability was $117.9 million and the remaining 31 monthly principal payments of $4.2 million each totaled $130.2 million. The prepayment resulted in a gain on lease termination of $3.3 million related to the difference between the book value of $117.9 million and the cash payment of $114.6 million.
