Five-Year Revolving Credit Facility—In June 2014, we entered into an amended and restated bank credit agreement, which established a $3.0 billion unsecured five-year revolving credit facility, that is scheduled to expire on June 28, 2019 (the “Five-Year Revolving Credit Facility”). Among other things, the Five-Year Revolving Credit Facility includes limitations on creating liens, incurring subsidiary debt, transactions with affiliates, sale/leaseback transactions, mergers and the sale of substantially all assets. The Five-Year Revolving Credit Facility also includes a covenant imposing a maximum debt to tangible capitalization ratio of 0.6 to 1.0. Borrowings under the Five-Year Revolving Credit Facility are subject to acceleration upon the occurrence of an event of default, borrowings are guaranteed by Transocean Ltd. and may be prepaid in whole or in part without premium or penalty.

We may borrow under the Five-Year Revolving Credit Facility at either (1) the adjusted London Interbank Offered Rate (“LIBOR”) plus a margin (the “Five-Year Revolving Credit Facility Margin”), which ranges from 1.125 percent to 2.0 percent based on the credit rating of our non-credit enhanced senior unsecured long-term debt (“Debt Rating”), or (2) the base rate specified in the credit agreement plus the Five-Year Revolving Credit Facility Margin, less one percent per annum. Throughout the term of the Five-Year Revolving Credit Facility, we pay a facility fee on the daily unused amount of the underlying commitment which ranges from 0.15 percent to 0.35 percent depending on our Debt Rating. In the three months ended March 31, 2015, our Debt Rating was reduced, and as a result, effective March 19, 2015, the Five-Year Revolving Credit Facility Margin increased to 1.75 percent from 1.5 percent and the facility fee increased to 0.275 percent from 0.225 percent. At March 31, 2015, we had no borrowings outstanding or letters of credit issued, and we had $3.0 billion of available borrowing capacity under the Five-Year Revolving Credit Facility.

5.05% Senior Notes, 6.375% Senior Notes and 7.35% Senior Notes—In December 2011, we issued $1.0 billion aggregate principal amount of 5.05% Senior Notes due December 2016 (the “5.05% Senior Notes”), $1.2 billion aggregate principal amount of 6.375% Senior Notes due December 2021 (the “6.375% Senior Notes”) and $300 million aggregate principal amount of 7.35% Senior Notes due December 2041 (the “7.35% Senior Notes”). The interest rates for the notes are subject to adjustment from time to time upon a change to our Debt Rating. In the three months ended March 31, 2015, our Debt Rating was reduced and, as a result, effective June 15, 2015, the interest rates on the 5.05% Senior Notes, the 6.375% Senior Notes and the 7.35% Senior Notes will increase 0.5 percent from the stated rate to 5.55 percent, 6.875 percent and 7.85 percent, respectively. At March 31, 2015, the aggregate outstanding principal amount of the 5.05% Senior Notes, the 6.375% Senior Notes and the 7.35% Senior Notes was $1.0 billion, $1.2 billion and $300 million, respectively.

2.5% Senior Notes and 3.8% Senior Notes—In September 2012, we issued $750 million aggregate principal amount of 2.5% Senior Notes due October 2017 (the “2.5% Senior Notes”) and $750 million aggregate principal amount of 3.8% Senior Notes due October 2022 (the “3.8% Senior Notes”). The interest rates for the notes are subject to adjustment from time to time upon a change to our Debt Rating. In the three months ended March 31, 2015, our Debt Rating was reduced and, as a result, effective April 15, 2015, the interest rates on the 2.5% Senior Notes and the 3.8% Senior Notes will increase 0.5 percent from the stated rate to 3.0 percent and 4.3 percent, respectively. At March 31, 2015, the aggregate outstanding principal amount of the 2.5% Senior Notes and the 3.8% Senior Notes was $750 million each.

Eksportfinans Loans—We have borrowings under the Loan Agreement dated September 12, 2008 and the Loan Agreement dated November 18, 2008, between one of our subsidiaries and Eksportfinans ASA (together, the “Eksportfinans Loans”).

The Eksportfinans Loans require collateral to be held by a financial institution through expiration (the “Aker Restricted Cash Investments”). At March 31, 2015 and December 31, 2014, the aggregate principal amount of the Aker Restricted Cash Investments was NOK 2.3 billion and NOK 2.8 billion, respectively, equivalent to approximately $290 million and $370 million, respectively.
