| Note 1—Nature of Business | |
| On June 30, 2014, Paragon Offshore Limited was an indirect wholly owned subsidiary of Noble Corporation plc (“Noble”) incorporated under the laws of England and Wales. On July 17, 2014, Paragon Offshore Limited re-registered under the Companies Act 2006 as a public limited company under the name of Paragon Offshore plc (together with its subsidiaries, “Paragon,” the “Company,” “we,” “us” or “our”). | |
| Subsequent to June 30, 2014, Noble transferred to us the assets and liabilities (the “Separation”) constituting most of Noble’s standard specification drilling units and related assets, liabilities and business. On August 1, 2014, Noble made a pro rata distribution to its shareholders of all of our issued and outstanding ordinary shares (the “Distribution” and, collectively with the Separation, the “Spin-Off”). In connection with the Distribution, Noble shareholders received one ordinary share of Paragon for every three ordinary shares of Noble owned. Noble owned 84.8 million ordinary shares of Paragon as of July 23, 2014, Noble’s record date for the Distribution. | |
| We are a pure-play global provider of standard specification offshore drilling rigs which includes 34 jackups and eight floaters (five drillships and three semisubmersibles), and one floating production storage and offloading unit (“FPSO”). We refer to our semisubmersibles and drillships collectively as “floaters.” We also operate the Hibernia platform offshore of Canada. Our primary business is to contract our drilling rigs, related equipment and work crews to conduct oil and gas drilling and workover operations for our exploration and production customers on a dayrate basis around the world. |

| Note 2—Significant Accounting Policies | |
| Management Estimates | |
| The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates and assumptions used in preparation of these consolidated financial statements. |

| Note 3—Related Party Accounts Payable | |
| Prior to the Distribution on August 1, 2014, Noble paid for certain administrative functions on our behalf. As of June 30, 2014, Noble had incurred $1.3 million of such expenses related to rating agency fees in connection with our debt issuance, discussed below, and $0.5 million related to registration fees. These costs are accumulated within “Other assets” and “Related party accounts payable.” |

| Note 4—Debt | |
| On June 17, 2014, we entered into a senior secured revolving credit agreement with lenders that provided commitments in the amount of $800 million (the “Revolving Credit Facility”). Subject to the satisfaction of certain conditions, we may obtain up to $800 million of letters of credit and up to $80 million of swingline loans under the Revolving Credit Facility. The Revolving Credit Facility has a term of five years after the funding date. Borrowings under the Revolving Credit Facility bear interest, at our option, at either (i) an adjusted LIBOR, plus a margin ranging between 1.50% to 2.50%, depending on our leverage ratio, or (ii) the Base Rate, which is calculated as the greatest of (1) a fluctuating rate of interest publicly announced by JPMorgan Chase Bank, N.A., as its “prime rate,” (2) the U.S. federal funds effective rate plus 0.50% and (3) the one month LIBOR Rate plus 1.00%, plus a margin ranging between 0.50% to 1.50%, depending on our leverage ratio. Issuance of Letters of Credit reduces availability to borrow under the Revolving Credit Facility. | |
| On July 18, 2014, we issued $1.08 billion of senior notes (the “Senior Notes”) and also borrowed $650 million under a term loan facility (the “Term Loan Facility”). The Term Loan Facility is secured by all of our rigs except three, which are currently cold-stacked. The proceeds from the Term Loan Facility and the Senior Notes were used to repay $1.7 billion of intercompany indebtedness to Noble incurred as partial consideration for the Separation. The Senior Notes consisted of $500 million of 6.75% senior notes and $580 million of 7.25% senior notes, which mature on July 15, 2022 and August 15, 2024, respectively. The Senior Notes were issued without an original issue discount. Borrowings under the term loan facility bear interest at an adjusted LIBOR rate plus 2.75%, subject to a minimum LIBOR rate of 1% or a base rate plus 1.75%, at our option. The Term Loan Facility matures in July 2021. The loans under the Term Loan Facility were issued with 0.5% original issue discount. | |
| The covenants and events of default under our Revolving Credit Facility, Senior Notes, and Term Loan Facility are substantially similar. The agreements governing these obligations contain covenants that place restrictions on certain merger and consolidation transactions; our ability to sell or transfer certain assets; payment of dividends; making distributions; redemption of stock; incurrence or guarantee of debt; issuance of loans; prepayment, redemption of certain debt, as well as incurrence or assumption of certain liens. In addition to these covenants, the Revolving Credit Facility includes a covenant requiring us to maintain a net leverage ratio, defined as total debt net of cash and cash equivalents, divided by earnings excluding interest, taxes, depreciation and amortization charges, not greater than 4.00 to 1.00 and a covenant requiring us to maintain a minimum interest coverage ratio, defined as interest expense divided by earnings excluding interest, taxes, depreciation and amortization charges, of 3.00 to 1.00. |
