SUBSEQUENT EVENT	SUBSEQUENT EVENT On May 2, 2017, we entered into the Fourth Amendment to the Credit Facility Agreement (the "Fourth Amendment"). The Fourth Amendment increased the total financing capacity available under the Credit Facility Agreement to $5.2 billion, consisting of (i) the $1.2 billion Revolving Credit Facility; (ii) the $1.5 billion Term A Loan; (iii) the $1.3 billion Term A-2 Loan; and (iv) a $1.2 billion term loan facility, which replaced the Term B Loan (the "Term B-2 Loan"). The aggregate outstanding debt under the Credit Facility Agreement did not change because we repaid certain outstanding amounts under the Term A Loan, the Term A-2 Loan and the Revolving Credit Facility in connection with the Fourth Amendment. As amended by the Fourth Amendment, the Credit Facility Agreement provides for an interest rate with respect to borrowings under the Term A Loan, the Term A-2 Loan and the Revolving Credit Facility of (a) in the case of Base Rate Loans (as defined in the Credit Facility Agreement), a base rate plus a margin ranging from 0.25% to 1.00%, in each case depending on our leverage ratio and (b) in the case of Eurocurrency Loans (as defined in the Credit Facility Agreement), a base rate plus a margin ranging from 1.25% to 2.00%, in each case depending on our leverage ratio. As amended by the Fourth Amendment, the Credit Facility Agreement provides for an interest rate with respect to the borrowings under the Term B-2 Loan of a base rate plus a margin of 1.00% in the case of Base Rate Loans and a base rate plus a margin of 2.00% in the case of Eurocurrency Loans. With respect to the Base Rate Loans, the base rate is the highest of (a) the Federal Funds Effective Rate (as defined in the Credit Facility Agreement) plus 0.50%, (b) the Bank of America prime rate and (c) the applicable Eurocurrency Base Rate (as defined in the Credit Facility Agreement) plus 1.00%. The Credit Facility Agreement also provides for a commitment fee with respect to borrowings under the Revolving Credit Facility at an applicable rate per annum ranging from 0.20% to 0.30% depending on our leverage ratio. Pursuant to the Fourth Amendment, the Term A Loan and the Term A-2 Loan mature, and the Revolving Credit Facility Agreement expires, on May 2, 2022. The Term B-2 Loan matures on April 22, 2023. The Term A Loan principal must be repaid in quarterly installments in the amount of 1.25% of principal through June 2019, increasing to 1.875% of principal through June 2021, and increasing to 2.50% of principal through March 2022, with the remaining principal balance due upon maturity in May 2022. The Term A-2 Loan principal must be repaid in quarterly installments of $1.7 million through June 2018, increasing to quarterly installments of $8.6 million through March 2022, with the remaining balance due upon maturity in May 2022. The Term B-2 Loan principal must be repaid in quarterly installments in the amount of 0.25% of principal through March 2023, with the remaining principal balance due upon maturity in April 2023. The Credit Facility Agreement contains customary affirmative and restrictive covenants, including, among others, financial covenants based on our leverage and fixed charge coverage ratios. The Credit Facility Agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations to be immediately due and payable. Pursuant to the Fourth Amendment, financial covenants require a leverage ratio for the period beginning May 2, 2017 no greater than: (i) 4.75 to 1.00 as of the end of any fiscal quarter ending during the period from May 2, 2017 through June 30, 2017; (ii) 4.50 to 1.00 as of the end of any fiscal quarter ending during the period from July 1, 2017 through June 30, 2018; (iii) 4.25 to 1.00 as of the end of any fiscal quarter ending during the period from July 1, 2018 through June 30, 2019; and (iv) 4.00 to 1.00 as of the end of any fiscal quarter ending thereafter. The fixed charge coverage ratio is required to be no less than 2.25 to 1.00.

On May 2, 2017, we entered into the Fourth Amendment to the Credit Facility Agreement (the "Fourth Amendment").

The aggregate outstanding debt under the Credit Facility Agreement did not change because we repaid certain outstanding amounts under the Term A Loan, the Term A-2 Loan and the Revolving Credit Facility in connection with the Fourth Amendment.

As amended by the Fourth Amendment, the Credit Facility Agreement provides for an interest rate with respect to borrowings under the Term A Loan, the Term A-2 Loan and the Revolving Credit Facility of (a) in the case of Base Rate Loans (as defined in the Credit Facility Agreement), a base rate plus a margin ranging from 0.25% to 1.00%, in each case depending on our leverage ratio and (b) in the case of Eurocurrency Loans (as defined in the Credit Facility Agreement), a base rate plus a margin ranging from 1.25% to 2.00%, in each case depending on our leverage ratio. As amended by the Fourth Amendment, the Credit Facility Agreement provides for an interest rate with respect to the borrowings under the Term B-2 Loan of a base rate plus a margin of 1.00% in the case of Base Rate Loans and a base rate plus a margin of 2.00% in the case of Eurocurrency Loans. With respect to the Base Rate Loans, the base rate is the highest of (a) the Federal Funds Effective Rate (as defined in the Credit Facility Agreement) plus 0.50%, (b) the Bank of America prime rate and (c) the applicable Eurocurrency Base Rate (as defined in the Credit Facility Agreement) plus 1.00%. The Credit Facility Agreement also provides for a commitment fee with respect to borrowings under the Revolving Credit Facility at an applicable rate per annum ranging from 0.20% to 0.30% depending on our leverage ratio.

Pursuant to the Fourth Amendment, the Term A Loan and the Term A-2 Loan mature, and the Revolving Credit Facility Agreement expires, on May 2, 2022. The Term B-2 Loan matures on April 22, 2023.

The Credit Facility Agreement contains customary affirmative and restrictive covenants, including, among others, financial covenants based on our leverage and fixed charge coverage ratios. The Credit Facility Agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations to be immediately due and payable.
