The total amount outstanding under the Revolving Credit Facility in the form of direct borrowings at September 29, 2017 was $235.0 million. The Company issued $2.5 million in letters of credit leaving $1.363 billion of available borrowing capacity under the Revolving Credit Facility at September 29, 2017. In addition, the Company had $259.6 million issued under separate, committed and uncommitted letter-of-credit facilities for total issued letters of credit of $262.1 million at September 29, 2017.

The Revolving Credit Facility expires in February 2020 and permits the Company to borrow under two separate tranches in U.S. dollars, certain specified foreign currencies, and any other currency that may be approved in accordance with the terms of the Revolving Credit Facility. Depending on the Company's Consolidated Leverage Ratio, borrowings under the Revolving Credit Facility will bear interest at either a euro rate plus a margin of between 1.0% and 1.5% or a base rate plus a margin of between 0% and 0.5%. The Revolving Credit Facility also provides for a financial letter of credit subfacility of $300.0 million, permits performance letters of credit, and provides for a $50.0 million subfacility for swingline loans. Letters of credit are subject to fees based on the Company's Consolidated Leverage Ratio at the time any such letter of credit is issued. The Revolving Credit Facility also provides an accordion feature that allows the Company and the lenders to increase the facility amount to $2.1 billion. The Company pays a facility fee of between 0.100% and 0.25% per annum depending on the Company's Consolidated Leverage Ratio. Amounts outstanding under the Revolving Credit Facility may be prepaid at the option of the Company without premium or penalty, subject to customary breakage fees in connection with the prepayment of eurocurrency loans. The Revolving Credit Facility contains affirmative, negative, and financial covenants customary for financings of this type including, among other things, limitations on certain other indebtedness, loans and investments, liens, mergers, asset sales and transactions with affiliates. In addition, the Revolving Credit Facility contains customary events of default. We were in compliance with these debt covenants at September 29, 2017.

On September 28, 2017, the Company entered into a Second Amendment to the Revolving Credit Facility, which provides for, among other things, an amendment to certain financial definitions used in the Revolving Credit Facility, including “Consolidated EBITDA”. These amendments are effective upon the consummation of the acquisition of CH2M.

On September 28, 2017, the Company entered into a $1.5 billion unsecured delayed-draw term loan facility (the “Term Loan Facility”) with a syndicate of financial institutions as lenders and letter of credit issuers and BNP Paribas as administrative agent, TD Bank, N.A. and U.S. Bank National Association as co-documentation agent, BNP Paribas Securities Corp., The Bank of Nova Scotia and Wells Fargo Securities, LLC as joint book runners, and as joint arrangers.

Subject to certain terms and conditions set forth therein, loans under the Term Loan Facility may be incurred on the day the CH2M acquisition is consummated in order to pay cash consideration for the acquisition, and to pay fees and expenses related to the acquisition and the Term Loan Facility. The Term Loan Facility has a three year maturity from the date of initial funding and permits the Company to borrow in U.S. dollars at a base rate or a eurocurrency rate. Depending on the Company’s consolidated leverage ratio, borrowings under the Term Loan Facility will bear interest at either a eurocurrency rate plus a margin of between 1.00% and 1.50% or a base rate plus a margin of between 0.00% and 0.50%. In addition, prior to the date the acquisition is consummated, the Company must pay a ticking fee of between 0.10% and 0.25% of unused commitments under the Term Loan Facility. Amounts outstanding under the Term Loan Facility may be prepaid at the option of the Company without premium or penalty, subject to customary breakage fees in connection with the prepayment of eurocurrency loans.

The Term Loan Facility contains affirmative, negative and financial covenants customary for financings of this type, including, among other things, limitations on certain other indebtedness, investments, liens, mergers, asset sales and transactions with affiliates. In addition, the Term Loan Facility contains customary events of default. We were in compliance with these covenants at September 29, 2017.
