Exchange Offers

In January 2017, we completed exchange offers (the "Exchange Offers") to exchange our outstanding 8.50% senior notes due 2019, 6.875% senior notes due 2020 and 4.70% senior notes due 2021 for 8.00% senior notes due 2024 and cash. The Exchange Offers resulted in the tender of $649.5 million aggregate principal amount of our outstanding senior notes that were settled and exchanged as follows (in millions):

Revolving Credit Facility

In October 2017, we amended our revolving credit facility ("Credit Facility") to extend the final maturity date by two years. Previously, our Credit Facility had a borrowing capacity of $2.25 billion through September 2019 that declined to $1.13 billion through September 2020. Subsequent to the amendment, our borrowing capacity is $2.0 billion through September 2019 and declines to $1.2 billion through September 2022. The credit agreement governing our revolving credit facility includes an accordion feature allowing us to increase the commitments expiring in September 2022 up to an aggregate amount not to exceed $1.5 billion.

Also in October, Moody's downgraded our credit rating from B1 to B2 and Standard & Poor's downgraded our credit rating from BB to B+. The Credit Facility amendment and the rating actions resulted in increases to the interest rates applicable to our borrowings. The applicable margin rates are 2.50% per annum for Base Rate advances and 3.50% per annum for LIBOR advances. In addition, our quarterly commitment fee increased as a result of the amendment and rating actions to 0.625% per annum on the undrawn portion of the $2.0 billion commitment.

The Credit Facility requires us to maintain a total debt to total capitalization ratio that is less than or equal to 60% and to provide guarantees from certain of our rig-owning subsidiaries sufficient to meet certain guarantee coverage ratios. The Credit Facility also contains customary restrictive covenants, including, among others, prohibitions on creating, incurring or assuming certain debt and liens (subject to customary exceptions, including a permitted lien basket that permits us to raise secured debt up to the lesser of $750 million or 10% of consolidated tangible net worth (as defined in the Credit Facility)); entering into certain merger arrangements; selling, leasing, transferring or otherwise disposing of all or substantially all of our assets; making a material change in the nature of the business; paying or distributing dividends on our ordinary shares (subject to certain exceptions, including the ability to continue paying a quarterly dividend of $0.01 per share); borrowings, if after giving effect to any such borrowings and the application of the proceeds thereof, the aggregate amount of available cash (as defined in the Credit Facility) would exceed $150 million; and entering into certain transactions with affiliates.

The Credit Facility also includes a covenant restricting our ability to repay indebtedness maturing after September 2022, which is the final maturity date of our Credit Facility. This covenant is subject to certain exceptions that permit us to manage our balance sheet, including the ability to make repayments of indebtedness (i) of acquired companies within 90 days of the completion of the acquisition or (ii) if, after giving effect to such repayments, available cash is greater than $250 million and there are no amounts outstanding under the Credit Facility.

As of September 30, 2017, we were in compliance in all material respects with our covenants under the Credit Facility. We had no amounts outstanding under the Credit Facility as of September 30, 2017 and December 31, 2016.

Our access to credit and capital markets depends on the credit ratings assigned to our debt. We no longer maintain an investment-grade status. Our current credit ratings, and any additional actual or anticipated downgrades in our credit ratings, could limit our available options when accessing credit and capital markets, or when restructuring or refinancing our debt. In addition, future financings or refinancings may result in higher borrowing costs and require more restrictive terms and covenants, which may further restrict our operations. With a credit rating below investment grade, we have no access to the commercial paper market.
