Short-term debt

The Company previously had a $375 million secured revolving credit facility (the "Cash Flow Revolver") that was originally set to expire on May 20, 2020.

On February 1, 2018, the Company entered into an amended Cash Flow Revolver (the "Amended Cash Flow Revolver") that increased the amount available under the facility to $500 million and extended the term to February 1, 2023 provided the Company’s available liquidity is at least equal to the outstanding balance of the Company’s senior secured notes due 2019 during the six month period prior to the maturity date of such notes, which is June 1, 2019. Subject to satisfaction of certain conditions, including obtaining additional commitments from existing and/or new lenders, the Company may increase the revolver commitments under the Amended Cash Flow Revolver by up to an additional $200 million and/or add new term loan commitments of up to $375 million.

The Company and certain subsidiary guarantors’ obligations under the Amended Cash Flow Revolver are secured by property of the Company and such guarantors, including, but not limited to cash, accounts receivables, inventory and the shares of the Company's subsidiaries, subject to limited exceptions.

The Amended Cash Flow Revolver requires the Company to comply with a minimum consolidated interest coverage ratio, measured at the end of each fiscal quarter, and at all times a maximum consolidated leverage ratio. The Amended Cash Flow Revolver contains customary affirmative covenants, including covenants regarding the payment of taxes and other obligations, maintenance of insurance, reporting requirements and compliance with applicable laws and regulations.

As of June 30, 2018, there were $233 million of borrowings and $9 million of letters of credit outstanding under the Amended Cash Flow Revolver.

As of June 30, 2018, certain foreign subsidiaries of the Company had a total of $69 million of short-term borrowing facilities, under which no borrowings were outstanding.

Debt covenants

The Company's Amended Cash Flow Revolver requires the Company to comply with certain financial covenants. In addition, the Company's debt agreements contain a number of restrictive covenants, including restrictions on incurring additional debt, making investments and other restricted payments, selling assets, paying dividends and redeeming or repurchasing capital stock and debt, subject to certain exceptions. The Company was in compliance with these covenants as of June 30, 2018.
