⁽¹⁾ LIBOR cannot be less than 1.00%. We have entered into interest rate swap agreements to mitigate the exposure to changes in LIBOR for $444.4million of the $674.9 million outstanding aggregate borrowings under our senior secured term loan facility at June 30, 2016. See Note 8, Accounting for derivative instruments and hedging activities for further details.

⁽²⁾ On a quarterly basis, we make a cash sweep payment to fund the principal balance, based on terms as defined in the credit agreement and disclosed below. The portion of the senior secured term loan facility classified as current is based on principal payments required to reduce the aggregate principal amount of New Term Loans outstanding to achieve a target principal amount that declines quarterly based on a pre-determined specified schedule.
