PACIFIC DRILLING S.A. AND SUBSIDIARIES
Notes to Condensed Consolidated Financial Statements (Unaudited)
Note 1 — Nature of Business
Pacific Drilling S.A. and its subsidiaries (“Pacific Drilling,” the “Company,” “we,” “us” or “our”) is an international offshore drilling contractor committed to becoming the preferred provider of ultra-deepwater drilling services to the oil and natural gas industry through the use of high-specification rigs. Our primary business is to contract our ultra-deepwater rigs, related equipment and work crews, primarily on a dayrate basis, to drill wells for our clients. As of March 31, 2013, the Company operates four drillships under client contract and has four drillships under construction at Samsung Heavy Industries (“SHI”), two of which are under client contract.
Note 2 — Significant Accounting Policies
Basis of Presentation — Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission. Pursuant to such rules and regulations, these financial statements do not include all disclosures required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation of financial position, results of operations and cash flows for the presented interim periods. Such adjustments are considered to be of a normal recurring nature unless otherwise identified. Operating results for the three months ended March 31, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any future period. The accompanying unaudited condensed consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and notes of the Company for the year ended December 31, 2012.
Principles of Consolidation — The unaudited condensed consolidated financial statements include the accounts of Pacific Drilling S.A. and consolidated subsidiaries that we control by ownership of a majority voting interest. We eliminate all intercompany transactions and balances in consolidation.
We currently are party to a Nigerian joint venture, Pacific International Drilling West Africa Limited (“PIDWAL”), which is fully controlled and 90% owned by us with 10% owned by Derotech Offshore Services Limited (“Derotech”), a privately-held Nigerian registered limited liability company. Derotech will not accrue the economic benefits of its interest in PIDWAL unless and until it satisfies certain outstanding obligations to us and a certain pledge is cancelled by us. Accordingly, we consolidate all PIDWAL interests and no portion of PIDWAL’s operating results is allocated to the noncontrolling interests. In addition to the joint venture agreement, we currently have marketing and logistic services agreements with Derotech and an affiliated company of Derotech. During the three months ended March 31, 2013 and 2012, we incurred fees of $2.1 million and $1.0 million, respectively, under the marketing and logistic services agreements.
Recently Issued Accounting Standards
Presentation of Comprehensive Income —In February 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update on the reporting of amounts reclassified out of accumulated other comprehensive income. This guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. We adopted the accounting standards update effective January 1, 2013. The adoption of the accounting standards update concerns presentation and disclosure only and did not have an impact on our consolidated financial position or results of operations.
Balance Sheet Offsetting —In December 2011, the FASB issued an accounting standards update that expands the disclosure requirements for the offsetting of assets and liabilities related to certain financial instruments and derivative instruments. The update requires disclosures of gross and net information for financial instruments and derivative instruments that are eligible for net presentation due to a right of offset, an enforceable master netting arrangement or similar agreement. We adopted the accounting standards update effective January 1, 2013. The adoption of the accounting standards update concerns presentation and disclosure only and did not have an impact on our consolidated financial position or results of operations.

On March 15, 2011, we entered into two contracts with SHI for the construction of the Pacific Khamsin and the Pacific Sharav , which are expected to be delivered to us at the shipyard in the second quarter of 2013 and fourth quarter of 2013, respectively. On March 16, 2012 and January 25, 2013, we entered into additional contracts for the construction of the Pacific Meltem and the Pacific Zonda , which are expected to be delivered to us at the shipyard in the second quarter of 2014 and the first quarter of 2015, respectively.
The SHI contracts for the Pacific Khamsin , the Pacific Sharav , the Pacific Meltem and the Pacific Zonda provide for an aggregate purchase price of approximately $2.0 billion for the acquisition of these four vessels, payable in installments during the construction process, of which we have made payments of $449.9 million through March 31, 2013. We anticipate making payments of approximately $799.3 million during the remainder of 2013, approximately $433.3 million in 2014 and approximately $336.4 million in 2015.
During the three months ended March 31, 2013 and 2012, we capitalized interest costs of $18.2 million and $10.1 million, respectively, on assets under construction.

(collectively, the “PFA Borrowers”), and Pacific Drilling Limited (the “Guarantor”) (collectively, the “PFA Borrowing Group”) entered into a project facilities agreement with a group of lenders to finance the construction, operation and other costs associated with the Pacific Bora , the Pacific Mistral , the Pacific Scirocco and the Pacific Santa Ana , (as amended on November 16, 2010, as amended and restated on March 30, 2011 and as further amended and restated on March 30, 2012, the “Original Project Facilities Agreement”). On April 19, 2012, in connection with the Temporary Import Bond Facilities described below, the PFA Borrowing Group amended and restated the Original Project Facilities Agreement by entering into the Third Amended and Restated Project Facilities Agreement (the “Project Facilities Agreement” or “PFA”). On December 28, 2012, the PFA Borrowing Group entered into the Second Amendment Agreement in respect of the Project Facilities Agreement, which changed the frequency of amortization payments from every six months to every three months.
The Project Facilities Agreement includes a term loan with respect to the Pacific Bora , a term loan with respect to the Pacific Mistral , a term loan with respect to the Pacific Scirocco and a term loan with respect to the Pacific Santa Ana (each, a “PFA Term Loan” and, collectively, the “PFA Term Loans” or the “PFA Term Loan Facility”). Each PFA Term Loan consists of three tranches: one provided by a syndicate of ten commercial banks (the “PFA Commercial Tranche”), one provided by the Ministry of Trade and Industry of the Norwegian government (and guaranteed by the Norwegian Guarantee Institute for Export Credits) (the “PFA GIEK Tranche”) and one provided by The Export-Import Bank of Korea (the “PFA KEXIM Tranche”).
In November 2010, we borrowed $450 million under the Bora Term Loan. During 2011, we borrowed $450 million, $375 million and $450 million under the Mistral Term Loan, the Scirocco Term Loan and the Santa Ana Term Loan, respectively. Under the Scirocco Term Loan, $75 million of the aggregated amount available was cancelled, resulting in our collective final borrowings equaling $1.725 billion under the Project Facilities Agreement.
Borrowings under the PFA Term Loans bear interest at the London Interbank Offered Rate (“LIBOR”) plus an applicable margin. Prior to the effective date of the first drilling contract in respect of a PFA Borrower’s drillship, the applicable margin under the relevant PFA Term Loan is 4% per annum. Subsequent to the effective date of the first drilling contract in respect of such PFA Borrower’s drillship and until 12 months after delivery of all four drillships, the applicable margin is 3.5% per annum. Subsequent to

12 months after the delivery of all four drillships, the applicable margin is based on the PFA Borrowing Group’s historical debt service coverage ratio. If the ratio is not greater than 125%, the applicable margin is 3.5% per annum. If the ratio is greater than 125%, the applicable margin is 3% per annum. Interest is payable every three months. As of March 31, 2013, each PFA Term Loan bore interest at LIBOR plus 3.0% per annum.
During the three months ended March 31, 2013 and 2012, we incurred $11.8 million and $17.7 million, respectively, of interest expense on the PFA Term Loans of which $0 and $7.1 million, respectively, was recorded to property and equipment as capitalized interest.
The PFA Commercial Tranche under the PFA Term Loan Facility matures on October 31, 2015, and the PFA GIEK Tranche and the PFA KEXIM Tranche each mature on October 31, 2019. Each PFA Term Loan requires a residual debt payment of $200 million at maturity of the PFA Commercial Tranche. The PFA GIEK Tranche and the PFA KEXIM Tranche each contain put options exercisable if the PFA Commercial Tranche is not refinanced on terms acceptable to GIEK and/or KEXIM, respectively. If the PFA GIEK Tranche put option or the PFA KEXIM Tranche put option is exercised, each PFA Borrower must prepay, in full, the portion of all outstanding loans that relate to the PFA GIEK Tranche and/or the PFA KEXIM Tranche, as applicable, on the maturity date of the PFA Commercial Tranche, without any premium, penalty or fees of any kind.
Borrowings under the PFA Commercial Tranche may be prepaid in whole or in part with a 1% penalty on the amount prepaid if such prepayment takes place within one year after the delivery of the fourth drillship, and no penalty thereafter. Borrowings under the PFA GIEK Tranche and the PFA KEXIM Tranche may be prepaid in whole or in part with a 0.5% penalty.
With respect to the term loans relating to the Pacific Bora , the Pacific Mistral , the Pacific Scirocco and the Pacific Santa Ana , we are required to make amortization payments of $12.5 million, $15.6 million, $10.9 million and $15.6 million, respectively, every three months, with the residual debt payment of $200 million each due in October 2015.
The Project Facilities Agreement contains events of default that are usual and customary for a financing of this type, size and purpose. Upon the occurrence of an event of default, borrowings under the Project Facilities Agreement are subject to acceleration.
As of March 31, 2013, we were in compliance with all Project Facilities Agreement covenants.
2015 Senior Unsecured Bonds
In February 2012, we completed a private placement of 8.25% senior unsecured U.S. dollar denominated bonds due 2015 (the “2015 Senior Unsecured Bonds”) in aggregate principal amount of $300 million to eligible purchasers. The bonds bear interest at 8.25% per annum, payable semiannually on February 23 and August 23, and mature on February 23, 2015.
During the three months ended March 31, 2013 and 2012, we incurred $6.2 million and $2.5 million, respectively, of interest expense on the 2015 Senior Unsecured Bonds of which $5.9 million and $1.1 million, respectively, was recorded to property and equipment as capitalized interest.
As of March 31, 2013, we were in compliance with all 2015 Senior Unsecured Bonds covenants.
2017 Senior Secured Notes
In November 2012, Pacific Drilling V Limited (“PDV”), an indirect, wholly-owned subsidiary of the Company, completed a private placement of $500 million (the “2017 Senior Secured Notes”) in aggregate principal amount of 7.25% senior secured U.S. dollar denominated notes due 2017 to eligible purchasers. The 2017 Senior Secured Notes are fully and unconditionally guaranteed by Pacific Drilling S.A. on a senior unsecured basis. The 2017 Senior Secured Notes constituted a new series of debt securities under an indenture dated as of November 28, 2012, among PDV, the Company and each subsidiary guarantor from time to time party thereto, as guarantors, and Deutsche Bank Trust Company Americas, as Trustee and Collateral Agent.
The 2017 Senior Secured Notes were sold at 99.483% of par. The 2017 Senior Secured Notes bear interest at 7.25% per annum, payable semiannually on June 1 and December 1, commencing on June 1, 2013, and mature on December 1, 2017.
During the three months ended March 31, 2013, we incurred and capitalized interest expense of $9.2 million on the 2017 Senior Secured Notes. We did not incur interest expense on the 2017 Senior Secured Notes during the three months ended March 31, 2012.
As of March 31, 2013, we were in compliance with all 2017 Senior Secured Notes covenants.

Senior Secured Credit Facility Agreement
On February 19, 2013, Pacific Sharav S.à r.l. and Pacific Drilling VII Limited (collectively, the “SSCF Borrowers”), and the Company, as guarantor entered into a senior secured credit facility agreement with a group of lenders to finance the construction, operation and other costs associated with the Pacific Sharav and the Pacific Meltem (the “Senior Secured Credit Facility Agreement” or “SSCF”).
The SSCF includes a term loan (the “SSCF Term Loan”) which consists of two tranches: (i) a tranche of $500.0 million provided by a syndicate of nine commercial banks (the “SSCF Commercial Tranche”) and (ii) a tranche of $500.0 million provided by Eksportkreditt Norge AS (and guaranteed by the Norwegian Guarantee Institute for Export Credits) (the “SSCF GIEK Tranche”). The SSCF Term Loan will become available upon the satisfaction of customary conditions precedent, as described therein.
Borrowings under the SSCF Commercial Tranche bear interest at LIBOR plus a margin of 3.5%. Borrowings under the SSCF GIEK Tranche bear interest, at the SSCF Borrower’s option, at (i) LIBOR plus a margin of 1.50% (which margin may be reset 60 months after the first borrowing under the SSCF Term Loan) or (ii) at a Commercial Interest Reference Rate of (a) 3.96% for borrowings relating to the Pacific Sharav and (b) 2.37% for borrowings relating to the Pacific Meltem . Borrowings under the GIEK Tranche will also be subject to a guarantee fee of 2.00% per annum (the “SSCF GIEK Premium”). Undrawn commitments for the SSCF Term Loan shall bear a fee equal to (i) in the case of the SSCF Commercial Tranche, 40% of the margin for such tranche and (ii) in the case of the SSCF GIEK Tranche, 40% of the applicable margin for such tranche. In addition, the SSCF GIEK Tranche shall bear a commitment fee equal to 40% of the SSCF GIEK Premium.
The SSCF Commercial Tranche matures on the earlier of (i) five years following the delivery of the second vessel under the SSCF and (ii) May 31, 2019. Loans made with respect to each vessel under the SSCF GIEK Tranche matures twelve years following the delivery of the applicable vessel. The SSCF GIEK Tranche contains a put option exercisable if the SSCF Commercial Tranche is not refinanced or renewed on or before February 28, 2019. If the SSCF GIEK Tranche put option is exercised, each SSCF Borrower must prepay, in full, the portion of all outstanding loans that relate to the SSCF GIEK Tranche, on or before May 31, 2019, without any premium, penalty or fees of any kind. Amortization payments under the SSCF Term Loan are calculated on a 12 year repayment schedule and must be made every six months following the delivery of the relevant vessel.
During the three months ended March 31, 2013, we incurred and capitalized interest expense, including guarantee and commitment fees, of $1.6 million on the SSCF. We did not incur interest expense on the SSCF during the three months ended March 31, 2012.
As of March 31, 2013, we were in compliance with all SSCF covenants.
Temporary Import Bond Facilities
As part of the standard Nigerian importation requirements for equipment, we are required to either import the vessel into Nigeria on a permanent basis and pay import duties or apply for a Temporary Importation (“TI”) permit and put up a bond for the value of the import duties instead. In 2011, we entered into a temporary Standby Letter of Credit (“SBLC”) facility with Citibank, N.A. to support a TI bond for the Pacific Bora and into a separate temporary SBLC facilities with each of Citibank, N.A. and Standard Charter Bank to support a TI bond for the Pacific Scirocco .
Under the SBLC facility for the Pacific Bora , Citibank, N.A., as issuing bank, issued a letter of credit for the benefit of Citibank Nigeria denominated in the Nigerian currency, Naira, in the amount of approximately $99.8 million. This letter of credit provided credit support for the Bora TI Bond that was issued by Citibank Nigeria in favor of the Government of Nigeria Customs Service for the Pacific Bora .
Under the temporary SBLC facilities for the Pacific Scirocco , Citibank, N.A. and Standard Charter Bank, as issuing banks, each issued a letter of credit for the benefit of Citibank Nigeria and Standard Charter Bank Nigeria, respectively, denominated in Naira in the collective amount of approximately $109.5 million. These letters of credit provided credit support for the Scirocco TI Bond that was issued by Citibank Nigeria and Standard Charter Bank Nigeria, respectively, in favor of the Government of Nigeria Customs Service for the Pacific Scirocco .
On April 19, 2012, the temporary SBLC facilities for the Pacific Bora and the Pacific Scirocco were each replaced by a Letter of Credit Facility and Guaranty Agreement. Under the Letter of Credit Facility and Guaranty Agreement for the Bora TI Bond (the “Bora TI Facility”), Citibank, N.A., as administrative agent, issuing bank and arranger, has issued a letter of credit for the benefit of Citibank Nigeria in the amount of 14,884,342,426 Naira or approximately $94.5 million as of April 19, 2012. This letter of credit provides credit support for the Bora TI Bond that was issued by Citibank Nigeria in favor of the Government of Nigeria Customs Service for the Pacific Bora .

Under the Letter of Credit Facility and Guaranty Agreement for the Scirocco TI Bond (the “Scirocco TI Facility,” and, together with the Bora TI Facility, the “TI Facilities”), Citibank, N.A., as administrative agent, issuing bank and arranger, has issued letters of credit for the benefit of Citibank Nigeria and Standard Charter Bank Nigeria in the collective amount of 17,280,837,923 Naira or approximately $109.7 million as of April 19, 2012. These letters of credit provide credit support for the TI bonds that were issued by Citibank Nigeria and Standard Charter Bank Nigeria, respectively, in favor of the Government of Nigeria Customs Service for the Pacific Scirocco .
The TI Facilities require the Company to pay fees, in addition to customary fronting fees, calculated based on outstanding balances of the TI Bonds and each outstanding letter of credit. Fees on the TI Facilities are primarily based on 2.5% of the U.S. dollar equivalent of outstanding balances of the Bora TI Facility and the Scirocco TI Facility. During the three months ended March 31, 2013 and 2012, we incurred $1.7 million and $0.7 million, respectively, in interest expense on the TI Facilities.
As of March 31, 2013, we were in compliance with all TI Facilities covenants.
Note 5 — Share-Based Compensation
During the three months ended March 31, 2013 and 2012, we recorded share-based compensation expense of $1.8 million and $0.9 million in general and administrative expenses in our consolidated statements of operations, respectively. During the three months ended March 31, 2013 and 2012, we recorded share-based compensation expense of $0.3 million and $0 in contract drilling costs in our consolidated statements of operations, respectively.
Stock Options
The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model utilizing the assumptions noted in the table below. Given the insufficient historical data available regarding the volatility of the Company’s traded share price, expected volatility of the Company’s share price does not solely provide a reasonable basis for estimating volatility. Instead, the expected volatility utilized in our Black-Scholes valuation model is based on the volatility of the Company’s traded share price and the implied volatilities from the expected volatility of a representative group of our publicly listed industry peer group. Additionally, given the lack of historical data available, the expected terms of the options is calculated using the simplified method because the historical option exercise experience of the Company does not provide a reasonable basis for estimating expected term. Options granted by the Company generally vest 25% annually over four years, have a 10-year contractual term and will be settled in shares of our stock. The risk free interest rates are determined using the implied yield currently available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options.
During the three months ended March 31, 2013, the fair value of the options granted was calculated using the following weighted average assumptions:

 	  	2013 Stock
Options	 	
Expected volatility	  	 	47.3	% 	
Expected term (in years)	  	 	6.25	 	
Expected dividends	  	 	—

Note 6 — Derivatives
We are currently exposed to market risk from changes in interest rates. From time to time, we may enter into a variety of derivative financial instruments in connection with the management of our exposure to fluctuations in interest rates and to meet our debt covenant requirements. We do not enter into derivative transactions for speculative purposes; however, for accounting purposes, certain transactions may not meet the criteria for hedge accounting.
We entered into four interest rate swaps to reduce the variability of future cash flows in the interest payments for the variable-rate debt under the Project Facilities Agreement. We designated the interest rate swaps as cash flow hedges for accounting purposes. The interest rate swaps pay a fixed rate of interest and receive LIBOR. The fixed interest rate swap rates are 1.83%, 1.87%, 1.6% and

2.39% for the Bora Term Loan, Scirocco Term Loan, Mistral Term Loan and Santa Ana Term Loan, respectively. As of March 31, 2013 and December 31, 2012, the notional amounts of the Bora, Scirocco, Mistral and Santa Ana interest rate swaps were $350.0 million, $316.7 million, $331.3 million and $387.5 million, respectively. The notional amounts of the interest rate swaps amortize quarterly and will expire on October 31, 2015.
On December 28, 2012, management de-designated a portion of the Bora, Scirocco, Mistral and Santa Ana interest rate swaps from hedge accounting due to the change in payment frequency of principal payments resulting from the Second Amendment Agreement to the Project Facilities Agreement. Subsequent to de-designation, we account for the de-designated portion of the interest rate swaps on a mark-to-market basis, with both realized and unrealized gains and losses on the de-designated portion recorded currently in earnings in interest expense in our consolidated statements of operations.
The table below provides data about the fair values of derivatives that are designated as hedge instruments as of March 31, 2013 and December 31, 2012:

As of March 31, 2013, the estimated amount of net losses associated with derivative instruments that would be reclassified to earnings during the next twelve months is $17.7 million. During the three months ended March 31, 2013, we reclassified $5.3 million to interest expense and $0.2 million to depreciation from accumulated other comprehensive income.

Note 7 — Fair Value Measurements
We have estimated fair value by using appropriate valuation methodologies and information available to management as of March 31, 2013 and December 31, 2012. Considerable judgment is required in developing these estimates, and accordingly, estimated values may differ from actual results.
The estimated fair value of accounts receivable, accounts payable and accrued expenses approximates their carrying value due to their short-term nature. Additionally, the estimated fair value of current and noncurrent restricted cash approximates its carrying value as it consists of cash and cash equivalent balances. The estimated fair value of our PFA and SSCF debt approximates carrying value because the variable rates approximate current market rates. As of March 31, 2013, we estimated the fair value of our 2015 Senior Unsecured Bonds and our 2017 Senior Secured Notes to be approximately $310.9 million and $531.3 million compared to their carrying value of $300.0 million and $497.6 million. As of December 31, 2012, we estimated the fair value of our 2015 Senior Unsecured Bonds and our 2017 Senior Secured Notes to be approximately $308.9 million and $512.5 million, respectively, compared to their carrying values of $300.0 million and $497.5 million, respectively. We estimate the fair values of our variable-rate and fixed-rate debts using significant other observable inputs, which represent Level 2 fair value measurements.
The following table presents the carrying value and estimated fair value of our financial instruments recognized at fair value on a recurring basis:

Interest rate swaps	  	$	47,006	 	  	 	—  	  	  	 	47,006	 	  	 	—  	  	
We use an income approach to value assets and liabilities for outstanding interest rate swaps. These contracts are valued using a discounted cash flow model that calculates the present value of future cash flows under the terms of the contracts using market information as of the reporting date, such as prevailing interest rates. The determination of the fair values above incorporates various factors, including the impact of the counterparty’s non-performance risk with respect to the Company’s financial assets and the Company’s non-performance risk with respect to the Company’s financial liabilities. The Company has not elected to offset the fair value amounts recognized for multiple derivative instruments with master netting arrangements executed with the same counterparty, but report them gross on its consolidated balance sheets.
Refer to Note 6 for further discussion of the Company’s use of derivative instruments and their fair values.
Note 8—Commitments and Contingencies
Commitments —As of March 31, 2013, Pacific Drilling had no material commitments other than commitments related to deepwater drillship construction purchase commitments discussed in Note 3. Funding of the construction of the Pacific Zonda will require additional financing, which is uncommitted at this time.
Our ability to meet these commitments and ongoing working capital needs will depend in part on our future operating and financial performance, which is dependent on cash flow generated from operating and financing activities and available cash balances. Our liquidity fluctuates depending on a number of factors, including, among others, our revenue efficiency and the timing of collecting accounts receivable as well as amounts paid for operating costs. We believe that our cash on hand and cash flows generated from operating and financing activities will provide sufficient liquidity over the next twelve months to fund our working capital needs, amortization payments on our long-term debt and anticipated capital expenditures for the Company’s ultra-deepwater drillship construction projects.

Contingencies — It is to be expected that we and our subsidiaries will be routinely involved in litigation and disputes arising in the ordinary course of our business. On April 16, 2013, Transocean filed a complaint against us in the United States District Court for the Southern District of Texas alleging infringement of their dual activity patents. Transocean seeks relief in the form of a permanent injunction, compensatory damages, enhanced damages, court costs and fees. We do not believe that ultimate liability, if any, resulting from any such pending litigation will have a material adverse effect on our financial condition or results of operations. Dual activity drilling is not to be confused with dual gradient drilling.
We maintain loss of hire insurance that becomes effective 45 days after an accident or major equipment failure covered by hull and machinery insurance, resulting in a downtime event and extends for 180 days. In the third quarter 2011, the Pacific Scirocco underwent repairs and upgrades to ensure engine reliability, which was a covered event under our loss of hire policy that resulted in the $23.7 million of loss of hire insurance recovery recognized during the three months ended March 31, 2012.

Note 10 — Supplemental Cash Flow Information
Capital expenditures in our consolidated statements of cash flows include the effect of changes in accrued capital expenditures, which are capital expenditures that were accrued but unpaid at period end. We have included these amounts in accounts payable, accrued expenses and accrued interest in our consolidated balance sheets as of March 31, 2013 and 2012. During the three months ended March 31, 2013 and 2012, capital expenditures includes the increase in accrued capital expenditures of $4.1 million and the decrease in accrued capital expenditures of $9.1 million in our consolidated statements of cash flows, respectively.
During the three months ended March 31, 2013 and 2012, non-cash amortization of deferred financing costs and accretion of debt discount totaling $1.5 million, were capitalized to property and equipment. Accordingly, these amounts are excluded from capital expenditures in our consolidated statements of cash flows for the three months ended March 31, 2013 and 2012.

 Item 2 — Operating and Financial Review and Prospects
Overview
We are an international offshore drilling contractor committed to becoming the preferred provider of ultra-deepwater drilling services to the oil and natural gas industry through the use of high-specification drilling rigs. Our primary business is to contract our ultra-deepwater drilling rigs, related equipment and work crews, primarily on a dayrate basis, to drill wells for our clients. Led by a team of seasoned professionals with significant experience in the oil services and ultra-deepwater drilling sectors, we specialize in the technically demanding segments of the offshore drilling business.
We are primarily focused on the ultra-deepwater segment of the rig market. The term “ultra-deepwater,” as used in the drilling industry to denote a particular segment of the market, can vary and continues to evolve with technological improvements. We generally consider ultra-deepwater to begin at water depths of more than 7,500 feet and to extend to the maximum water depths in which rigs are capable of drilling, which is currently approximately 12,000 feet. Although we are primarily focused on the ultra-deepwater segment, our drillships can and do operate effectively in water depths as shallow as 2,000 feet, and as such we also compete to provide services at shallower depths than ultra-deepwater. While not currently a core focus for our business, our drillships are also capable of operating in harsh environment areas, where there are typically rougher sea conditions.
Drilling Contracts for our Fleet
We currently operate four drillships and have four drillships under construction, two of which are under client contract. The current status of our contracted drillships is as follows:
 
 	•	 	The Pacific Bora entered service in Nigeria on August 26, 2011 under a three-year contract with a subsidiary of Chevron Corporation (“Chevron”).	
 
 	•	 	The Pacific Scirocco entered service in Nigeria on December 31, 2011 under a one-year contract with a subsidiary of Total S.A. (“Total”). In April 2012, Total exercised an initial one-year option, and in April 2013, Total exercised a subsequent one-year option extending the contract term to January 2015.	
 
 	•	 	The Pacific Mistral entered service in Brazil on February 6, 2012 under a three-year contract with Petróleo Brasileiro S.A. (“Petrobras”).	
 
 	•	 	The Pacific Santa Ana entered service in the U.S. Gulf of Mexico on May 4, 2012 under a five-year contract with a subsidiary of Chevron.	
 
 	•	 	Upon delivery, the Pacific Khamsin is expected to enter service in Nigeria in the fourth quarter of 2013 under a two-year contract with a subsidiary of Chevron. Chevron also has the right to deploy the drillship in one of several additional countries, including Liberia and certain countries in Asia.	
 
 	•	 	Upon delivery, the Pacific Sharav is expected to enter service in the U.S. Gulf of Mexico in the second quarter of 2014 under a five-year contract with a subsidiary of Chevron.	
Newbuild Drillships
The Pacific Khamsin and the Pacific Sharav are currently under construction by SHI, and are scheduled for delivery in the second and fourth quarters of 2013, respectively. In March 2012, we entered into a contract with SHI for the construction of the Pacific Meltem , which is expected to be delivered in the second quarter of 2014. In January 2013, we entered into an additional contract with SHI for the construction of the Pacific Zonda , which is expected to be delivered in the first quarter of 2015.
Significant Developments
In January 2013, we entered into an additional contract with SHI for the construction of the Pacific Zonda , which is expected to be delivered in the first quarter of 2015.
On February 19, 2013, the SSCF Borrowing Group entered into a senior secured credit facility agreement with a group of lenders to finance the construction, operation and other costs associated with the Pacific Sharav and the Pacific Meltem . See Note 4 to the unaudited condensed consolidated financial statements.
On April 4, 2013, Total elected to exercise a one-year option to extend the firm contract term for the Pacific Scirocco to January 2015. The additional one-year term increased our contract backlog upon exercise by approximately $180 million.
General Industry Trends and Outlook
Historically, operating results in the offshore contract drilling industry have been cyclical and directly related to the demand for and the available supply of drilling rigs. However, since factors that impact offshore exploration and development spending are beyond our control, and rig demand dynamics can shift quickly, it is difficult for us to predict future industry conditions, demand trends or operating results.

Table of Contents
Drilling Rig Supply
During the first quarter of 2013, offshore drilling contractors placed 3 shipyard orders to build additional ultra-deepwater semi-submersibles and drillships. We estimate there are approximately 55 ultra-deepwater rigs delivered or scheduled for delivery from January 1, 2013 until the end of 2015, 24 of which have not yet been announced as contracted to clients. Due to the long lead times involved in rig construction, rigs to be delivered in this timeframe would need to have been ordered already and therefore supply of ultra-deepwater units through the end of 2015 can be calculated at 165 with some certainty at this time. Beyond this time frame, the supply is uncertain and any projections have diminished predictive value.
Drilling Rig Demand
Demand for our drillships is a function of the worldwide levels of offshore exploration and development spending by oil and gas companies, which is influenced by a number of factors. The type of projects that modern drillships undertake are generally located in deeper water, more capital intensive and longer lasting than those of older or less capable drilling rigs, which makes these projects less sensitive to short-term oil price fluctuations. Therefore, dayrates and utilization for modern drillships are typically less sensitive to short-term oil price movements than those of older or less capable drilling rigs. Furthermore, long-term expectations about future oil and natural gas prices have historically been a key driver for deepwater and ultra-deepwater exploration and development spending. Our clients’ drilling programs are also affected by the global economic and political climate, access to quality drilling prospects, exploration success, perceived future availability and lead time requirements for drilling equipment, emphasis on deepwater exploration and production versus other areas and advances in drilling technology.
The first quarter of 2013 saw oil and global non-U.S. natural gas prices exhibit considerable volatility while continuing above the levels needed for sufficient return on investment for our clients. While questions remain regarding global economic stability, GDP growth continued to be positive in key emerging markets and North America. Both tendering activity and deepwater exploratory success continued, most notably in the U.S. Gulf of Mexico, and there were no material adverse changes to access or regulations worldwide.
Supply and Demand Balance
These factors resulted in a tight supply-demand balance for modern drillships in the first quarter of 2013, with steady dayrates and near 100% utilization. While we believe that these trends will continue to benefit us and that the demand for these rigs will continue to meet or exceed supply, our markets may be adversely affected by industry conditions that are beyond our control. For more information on this and other risks to our business and our industry, please read “Risk Factors” in our 2012 Annual Report.
Contract Backlog
Our contract backlog includes firm commitments only, which are represented by signed drilling contracts. As of May 1, 2013, our contract backlog was approximately $3.3 billion and was attributable to revenues we expect to generate on the Pacific Bora , the Pacific Scirocco , the Pacific Mistral , the Pacific Santa Ana , the Pacific Khamsin and the Pacific Sharav under firm contracts with Chevron, Total and Petrobras. We calculate our contract backlog by multiplying the contractual dayrate by the minimum number of days committed under the contracts (excluding options to extend), assuming full utilization, and also include mobilization fees, upgrade reimbursements and other revenue sources, such as the standby rate during upgrades, as stipulated in the contract.
The actual amounts of revenues earned and the actual periods during which revenues are earned may differ from the amounts and periods shown in the table below due to various factors, including shipyard and maintenance projects, downtime and other factors. In addition, our contracts customarily provide for termination at the election of the client with an “early termination payment” to be paid to us if a contract is terminated prior to the expiration of the fixed term. However, under certain limited circumstances, such as destruction of a drilling rig, our bankruptcy, sustained unacceptable performance by us or delivery of a rig beyond certain grace and/or liquidated damages periods, no early termination payment would be paid. Accordingly, the actual amount of revenues earned may be substantially lower than the backlog reported.

(a)	Contract also provides for two successive un-priced one-year options.	
(b)	The contractual dayrate for the Pacific Scirocco is currently $474,750, which is the average contract backlog revenue per day through January 7, 2014. Starting on January 8, 2014, the average contract backlog revenue per day will be $494,950 based on the contractual dayrate for the one-year option period through January 7, 2015. The contract also provides for a further two-year option with a contractual dayrate of $498,990, which expires in April 2014.	
(c)	Rounded to the nearest $1,000. Based on signed drilling contracts.	
(d)	On March 21, 2012, the Pacific Santa Ana was accepted and commenced its five-year contract with Chevron while mobilizing to the United States Gulf of Mexico. On May 4, 2012, the Pacific Santa Ana completed all necessary activities for commencement of revenue recognition and placing the Pacific Santa Ana into service in the United States Gulf of Mexico.	
(e)	Revenues earned and incremental costs incurred directly related to contract preparation and mobilization are deferred and recognized over the primary term of the drilling contract. Average contract backlog revenue per day for the Pacific Khamsin is calculated by dividing the contract backlog revenue which is recognized over the primary term of the drilling contract by the remaining number of days committed under the two-year contract. The drilling contract also includes $10 million in demobilization fees that are deferred and will be recognized as revenue in a lump sum upon conclusion of the drilling contract; accordingly, this $10 million is not included in the average contract backlog revenue per day for the Pacific Khamsin .	
(f)	Client has the right to deploy the rig in one of several countries, including Nigeria, Liberia and certain countries in Asia. The indicated contractual dayrate is based on expected deployment in Nigeria. The contract provides for a make-whole adjustment to the contractual dayrate for change in drilling locale.	
(g)	Contract also provides for a one-year option to be exercised at the client’s discretion prior to shipyard delivery of the drillship. The contractual dayrate of the one-year option period is $680,000.

Revenues. Revenues were $175.0 million for the three months ended March 31, 2013, compared to $117.4 million for the three months ended March 31, 2012. The revenue for the three months ended March 31, 2012 reflected a full quarter of operations from only the Pacific Bora and the Pacific Scirocco and a partial quarter of operations from the Pacific Mistral , which commenced operations on February 6, 2012. The increase in revenues during the three months ended March 31, 2013 reflects a full quarter of operations from our four operating drillships, including the Pacific Santa Ana , which commenced earning revenues on May 4, 2012.
Contract drilling revenue for the three months ended March 31, 2013 and 2012 also included $16.9 million and $19.3 million, respectively, in amortization of deferred revenue. The decrease in the amortization of deferred revenue is due to the expiration of the initial one-year primary term of the Pacific Scirocco on January 7, 2013.
During the three months ended March 31, 2013, our operating fleet of drillships achieved an average revenue efficiency of 90.3% compared to 88.9% during the three months ended March 31, 2012. Revenue efficiency is defined as actual contractual dayrate revenue (excludes mobilization fees, upgrade reimbursements and other revenue sources) divided by the maximum amount of total contractual dayrate revenue that could have been earned during such period. Revenue efficiency for the Pacific Bora and the Pacific Scirocco was negatively impacted by downtime due to planned unpaid maintenance on their blowout preventers in the first quarter of 2013, which reduced our average revenue efficiency by approximately 5.5%. These impacts were partially offset by the Pacific Mistral and the Pacific Santa Ana with both rigs achieving their highest quarterly revenue efficiency levels to date.
Contract drilling costs. Contract drilling costs were $84.5 million for the three months ended March 31, 2013, compared to $64.9 million for the three months ended March 31, 2012. The increase in contract drilling costs was primarily due to a full quarter of operations from our four operating drillships for the three months ended March 31, 2013, as opposed to a full quarter of operations from the Pacific Bora and the Pacific Scirocco and a partial quarter of operations from the Pacific Mistral in the first quarter of 2012.
During the three months ended March 31, 2013, direct rig related operating expenses were approximately $69.3 million or $192,000 per operating rig per day and shore-based and other support costs were approximately $5.6 million. During the three months ended March 31, 2012, direct rig related operating expenses were approximately $45.0 million or $190,500 per operating rig per day and shore-based and other support costs were approximately $5.2 million. During the three months ended March 31, 2013, direct rig related operating expenses included $5.0 million of reimbursable costs. These represent costs for the purchase of supplies, equipment, personnel services and other services provided at the request of our clients that are beyond the initial scope of the drilling contract.

Table of Contents
These costs, which are specifically reimbursed by our clients, have increased significantly over the past year. Although reimbursable costs do not negatively affect our profitability, these costs have resulted in an increase to our operating expenses. During the three months ended March 31, 2013 and 2012, direct rig related operating expenses per operating rig per day were approximately $178,000 and $186,000 excluding the impacts of reimbursable costs, respectively. The decrease in direct rig related operating expenses per operating rig per day excluding reimbursable costs during the three months ended March 31, 2013 is attributable to lower equipment and maintenance costs as compared to the three months ended March 31, 2012, which included rig startup costs for the Pacific Bora , the Pacific Scirocco and the Pacific Mistral .
Contract drilling costs for the first quarter of 2013 and 2012 additionally included $9.6 million and $14.7 million in amortization of deferred mobilization costs, respectively. The decrease in the amortization of deferred mobilization costs in the first quarter of 2013 as compared to the first quarter of 2012 is due to the expiration of the initial one-year primary term of the Pacific Scirocco on January 7, 2013.
General and administrative expenses . General and administrative expenses were $11.0 million for the three months ended March 31, 2013, compared to $12.4 million for the three months ended March 31, 2012. The decrease in general and administrative expenses was primarily due to $2.1 million in legal fees incurred during the first quarter of 2012 to make amendments to the Project Facilities Agreement in order to facilitate improvements in our corporate structure.
Depreciation expense . Depreciation expense was $36.5 million for the three months ended March 31, 2013, compared to $22.6 million for the three months ended March 31, 2012. The increase in depreciation expense was primarily due to a full quarter of operations from our four operating drillships.
Loss of hire insurance recovery. Income from loss of hire insurance recovery was $0 for the three months ended March 31, 2013, compared to $23.7 million for the three months ended March 31, 2012. As part of our hull and machinery policy, we maintain loss of hire insurance which carries a 45-day waiting period and an annual aggregate limit of 180 days. In the third quarter of 2011, the Pacific Scirocco underwent repairs and upgrades to ensure engine reliability, which was a covered event under our loss of hire policy. During the three months ended March 31, 2012, we received proceeds under the policy of $23.7 million.
Interest expense . Interest expense was approximately $22.8 million for the three months ended March 31, 2013, compared to $19.3 million for the three months ended March 31, 2012. The increase in interest expense was primarily due to interest expense on borrowings under our Project Facilities Agreement after the Pacific Mistral and the Pacific Santa Ana were placed into service on February 6, 2012 and May 4, 2012, respectively, which was partially offset by decreases in outstanding debt due to PFA repayments of principal and a decrease to the applicable margin from 3.5% to 3.0%.
Other income . Other income was approximately $0.2 million for the three months ended March 31, 2013, compared to $3.0 million for the three months ended March 31, 2012. The decrease primarily relates to lower foreign currency exchange gains.
Income taxes . In accordance with GAAP, we estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual or infrequent items, if any. For the three months ended March 31, 2013 and 2012, our effective tax rate was 26.4% and 26.0%, respectively.
The relationship between our provision for or benefit from income taxes and our pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, (b) changes in the blend of income that is taxed based on gross revenues versus pre-tax book income, and (c) our rig operating structures. Consequently, our income tax expense does not change proportionally with our pre-tax book income. Significant decreases in our pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The increase in our effective tax rate for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily relates to a change in the blend of forecasted income that is taxed based on gross revenues versus pre-tax book income.
Liquidity and Capital Resources
Liquidity
As of March 31, 2013 and December 31, 2012, we had $467.7 million and $605.9 million, respectively, of cash and cash equivalents. Additionally, as of March 31, 2013 and December 31, 2012, we had $172.2 million of restricted cash that primarily consisted of restricted cash accounts held with financial institutions as security for the borrowings under the Project Facilities Agreement and TI Bond Facilities.
Our liquidity requirements include funding ongoing working capital needs, repaying our outstanding indebtedness and anticipated capital expenditures, which is largely comprised of our progress payments for our ultra-deepwater drillship construction projects, and maintaining adequate cash reserves to compensate the effects of fluctuations in operating cash flows. Our ability to meet
 
22

Table of Contents
these liquidity requirements will depend in large part on our future operating and financial performance. Primary sources of funds for our short-term liquidity needs will be cash flow generated from operating and financing activities and available cash balances. Our liquidity fluctuates depending on a number of factors, including, among others, our revenue efficiency and the timing of collecting accounts receivable as well as amounts paid for operating costs. We believe that our cash on hand and cash flows generated from operating and financing activities will provide sufficient liquidity over the next twelve months to fund our working capital needs, amortization payments on our long-term debt and anticipated capital expenditures for our ultra-deepwater drillship construction projects. Our ability to meet our long-term liquidity requirements will depend in part on our ability to secure additional financing, which is uncommitted at this time, in order to fund construction of the Pacific Zonda .
As the parent company of our operating subsidiaries, we are not a party to any drilling contracts directly and are therefore dependent on receiving cash distributions from our subsidiaries. Surplus cash held in our subsidiaries owning the Pacific Bora , the Pacific Scirocco , the Pacific Mistral and the Pacific Santa Ana , which act as borrowers under the Project Facilities Agreement, is restricted until January 1, 2014 by the Project Facilities Agreement from transfer by intercompany loans and/or dividend payments to us. After January 1, 2014, transfers from these subsidiaries to us are permitted assuming we are in compliance with the provisions of the Project Facilities Agreement. As of March 31, 2013 and December 31, 2012, our borrowing subsidiaries held $1.7 billion of restricted net assets. We do not believe these restrictions will prevent us and other non-borrowing subsidiaries from meeting our respective liquidity needs.
Capital Expenditures and Working Capital Funding
In March 2011, we entered into two contracts with SHI for the construction of our fifth and sixth advanced-capability, ultra-deepwater drillships, the Pacific Khamsin and the Pacific Sharav . In March 2012, we entered into a contract with SHI for the construction of the Pacific Meltem . In January 2013, we entered into an additional contract with SHI for the construction of the Pacific Zonda .
The SHI contracts for the Pacific Khamsin, the Pacific Sharav , the Pacific Meltem and the Pacific Zonda provide for an aggregate purchase price of approximately $2.0 billion for the acquisition of these four vessels, payable in installments during the construction process, of which we have made payments of approximately $449.9 million through May 1, 2013. We anticipate making payments of approximately $874.9 million in 2013, approximately $433.3 million in 2014 and approximately $336.4 million in 2015. We expect the project cost for the Pacific Khamsin , the Pacific Sharav , the Pacific Meltem and the Pacific Zonda under construction to be approximately $608.3 million, $662.9 million, $627.8 million and $634.1 million, respectively, or $2.5 billion in total. The estimate of the project costs includes commissioning and testing and other costs for the drillships, but excludes capitalized interest. As of March 31, 2013, there are approximately $2.0 billion of remaining project costs for the Pacific Khamsin , the Pacific Sharav , the Pacific Meltem and the Pacific Zonda of which approximately $1.6 billion is remaining contractual commitments to SHI. The remaining project costs of $384 million for the Pacific Khamsin will be financed with existing cash balances primarily from proceeds under the 2017 Senior Secured Notes. We intend to finance the approximately $1.0 billion remaining project costs for the Pacific Sharav and the Pacific Meltem with our Senior Secured Credit Facility and existing cash balances. Additionally, we intend to finance the $608 million in remaining project costs for the Pacific Zonda with our existing cash balances, operating cash flow generation and additional future indebtedness, which is uncommitted at this time.

The increase in net cash provided by operating activities is primarily due to a full quarter of operations from our four operating drillships for the three months ended March 31, 2013, as opposed to a full quarter of operations from the Pacific Bora and the Pacific Scirocco and a partial quarter of operations from the Pacific Mistral in the first quarter of 2012. The net cash used in operating activities during the three months ended March 31, 2012 primarily resulted from payments for mobilization and operating expenses and increases in our accounts receivable balance for billings not yet collected.
The following table provides an analysis of our cash flow from investing activities for the three months ended March 31, 2013 and March 31, 2012:

The increase in net cash used in investing activities primarily resulted from higher amounts of progress payments for our drillships under construction and more spent on capital equipment upgrades during the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The decrease in restricted cash during the three months ended March 31, 2012 resulted from a release of restricted cash that was collateral for a letter of credit that was cancelled during the first quarter of 2012.

The decrease in cash from financing activities primarily resulted from decreases in proceeds from long-term debt, payments on the PFA and deferred financing costs. During the three months ended March 31, 2013, we completed an initial drawdown of $1.0 million in conjunction with the process to close the SSCF for which we also paid $21.4 million in deferred financing costs. Additionally, we paid $54.7 million in principal repayments on the PFA. During the three months ended March 31, 2012, we borrowed $300 million under the 2015 Senior Unsecured Bonds for which we paid $6.3 million in deferred financing costs.
Letters of Credit
As of March 31, 2013, we were contingently liable under certain performance, bid and custom bonds and letters of credit totaling $203.4 million primarily related to our TI Bond Facilities.
Description of Indebtedness
Project Facilities Agreement . The Project Facilities Agreement includes a Bora Term Loan, a Mistral Term Loan, a Scirocco Term Loan and a Santa Ana Term Loan. See Note 4 to the unaudited condensed consolidated financial statements.
8.25% Senior Unsecured Bonds due 2015 . In February 2012, we completed a private placement of $300 million in aggregate principal amount of 8.25% senior unsecured U.S. dollar denominated bonds due 2015 to eligible purchasers. The 2015 Senior Unsecured Bonds bear interest at 8.25% per annum, payable semiannually on February 23 and August 23, and mature on February 23, 2015. See Note 4 to the unaudited condensed consolidated financial statements.
7.25% Senior Secured Notes due 2017 . In November 2012, Pacific Drilling V Limited, an indirect, wholly-owned subsidiary of the Company, completed a private placement of $500 million in aggregate principal amount of 7.25% senior secured U.S. dollar denominated notes due 2017 to eligible purchasers. The notes were sold at 99.483% of par. The 2017 Senior Secured Notes bear interest at 7.25% per annum, payable semiannually on June 1 and December 1, commencing on June 1, 2013, and mature on December 1, 2017. See Note 4 to the unaudited condensed consolidated financial statements.
Senior Secured Credit Facility Agreement. On February 19, 2013, Pacific Sharav S.à r.l. and Pacific Drilling VII Limited, and the Company, as guarantor, entered into a senior secured credit facility agreement with a group of lenders to finance the construction, operation and other costs associated with the Pacific Sharav and the Pacific Meltem . See Note 4 to the unaudited condensed consolidated financial statements.
Temporary Import Bond Facilities . As part of the standard Nigerian importation requirements for equipment, we are required to either import the vessel into Nigeria on a permanent basis and pay import duties or apply for a TI permit and put up a bond for the value of the import duties instead. We have entered into Letter of Credit Facility and Guaranty Agreements that provide credit support for the TI Bonds issued in favor of the Government of Nigeria Customs Service for the Pacific Bora and the Pacific Scirocco. See Note 4 to the unaudited condensed consolidated financial statements.
Derivative Instruments and Hedging Activities
We may enter into derivative instruments from time to time to manage our exposure to fluctuations in interest rates and to meet our debt covenant requirements. We do not enter into derivative transactions for speculative purposes; however, for accounting purposes, certain transactions may not meet the criteria for hedge accounting. See Note 6 to the unaudited condensed consolidated financial statements.

(a)	Includes current maturities of long-term debt. In preparing the scheduled maturities of our debt, we assume certain holders of debt under the Project Facilities Agreement will exercise their options to accelerate the maturity date to October 31, 2015.	
(b)	Interest payments are based on our existing outstanding borrowings. It is assumed there is not a refinancing of existing long-term debt and there are no prepayments. Interest has been calculated using the interest rate of 1.83% for the Bora Term Loan, 1.87% for the Scirocco Term Loan, 1.60% for the Mistral Term Loan and 2.39% for the Santa Ana Term Loan based on the interest rate swap notional values for each respective Term Loan plus an estimated applicable margin for each of the Term Loans of 3.0%. Interest on the 2015 Senior Unsecured Bonds and the 2017 Senior Secured Notes is calculated at the fixed rate of 8.25% and 7.25%, respectively. Interest on the SSCF is based on existing outstanding borrowings and applicable Commercial Tranche and GIEK Tranche rates.	
(c)	Purchase obligations are agreements to purchase goods and services that are enforceable and legally binding, that specify all significant terms, including the quantities to be purchased, price provisions and the approximate timing of the transactions, which includes our purchase orders for goods and services entered into in the normal course of business.	
(d)	Amounts for ultra-deepwater drillships include amounts due under construction contracts.	
(e)	The long-term payable is due to the client for reimbursements of certain capital equipment upon the termination of the drilling contract with Chevron for the Pacific Bora . For purposes of the contractual obligations table, we assume the contract will terminate after its initial three-year period.	
Some of the figures included in the table above are based on estimates and assumptions about these obligations, including their duration and other factors. The contractual obligations we will actually pay in future periods may vary from those reflected in the tables because the estimates and assumptions are subjective.
Critical Accounting Estimates and Policies
The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date and the amounts of revenues and expenses recognized during the reporting period. On an ongoing basis, we evaluate our estimates and assumptions, including those related to allowance for doubtful accounts, financial instruments, depreciation of property and equipment, impairment of long-lived assets, income taxes, share-based compensation and contingencies. We base our estimates and assumptions on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from such estimates.
Our critical accounting estimates are important to the portrayal of both our financial condition and results of operations and require us to make difficult, subjective or complex assumptions or estimates about matters that are uncertain. We would report different amounts in our consolidated financial statements, which could be material, if we used different assumptions or estimates. We have discussed the development and selection of our critical accounting estimates with our Board of Directors and the Board of Directors has reviewed the disclosure of our critical accounting estimates. During the three months ended March 31, 2013, we have not made any material changes in accounting methodology.
For a discussion of the critical accounting policies and estimates that we use in the preparation of our unaudited condensed consolidated financial statements, see Item 5, “Operating and Financial Review and Prospects—Critical Accounting Estimates and Policies” in our 2012 Annual Report. During the three months ended March 31, 2013, there have been no material changes to the judgments, assumptions and estimates, upon which our critical accounting estimates are based. Significant accounting policies and recently issued accounting standards are discussed in Note 2 to our unaudited condensed consolidated financial statements in this Quarterly Report and in Note 2 to our consolidated financial statements included in our 2012 Annual Report.

FORWARD-LOOKING STATEMENTS
This Quarterly Report contains forward-looking statements that involve risks and uncertainties. Where any forward-looking statement includes a statement about the assumptions or bases underlying the forward-looking statement, we caution that, while we believe these assumptions or bases to be reasonable and made in good faith, assumed facts or bases almost always vary from the actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, our management expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and is believed to have a reasonable basis. We cannot assure you, however, that the statement of expectation or belief will result or be achieved or accomplished. These statements relate to analyses and other information that are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. Forward-looking statements are identified by their use of terms and phrases such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “will” and similar terms and phrases, including references to assumptions. Forward-looking statements involve risks and uncertainties that may cause actual future activities and results of operations to be materially different from those suggested or described in this Quarterly Report. These risks include the risks that are identified in the “Risk Factors” section of our 2012 Annual Report, and also include, among others, risks associated with the following:
 
 	•	 	the oil and gas market and its impact on demand for our services, including supply and demand for oil and gas and expectations regarding future energy prices;	
 
 	•	 	our substantial level of indebtedness;	
 
 	•	 	our need for cash to meet our debt service obligations;	
 
 	•	 	our limited number of assets and small number of clients;	
 
 	•	 	downtime of our drillships;	
 
 	•	 	competition within our industry;	
 
 	•	 	oversupply of rigs competing with our rigs;

 	•	 	our levels of operating and maintenance costs;	
 
 	•	 	availability of skilled workers and the related labor costs;	
 
 	•	 	compliance with governmental, tax, environmental and safety regulation;	
 
 	•	 	any non-compliance with the Foreign Corrupt Practices Act, the United Kingdom’s Anti-Bribery Act or any other anti bribery laws;	
 
 	•	 	reduced expenditures by oil and natural gas exploration and production companies;	
 
 	•	 	general economic conditions and conditions in the oil and natural gas industry;	
 
 	•	 	our dependence on key personnel;

Any forward-looking statements contained in this Quarterly Report should not be relied upon as predictions of future events. No assurance can be given that the expectations expressed in these forward-looking statements will prove to be correct. Actual results could differ materially from expectations expressed in the forward-looking statements if one or more of the underlying assumptions or expectations proves to be inaccurate or is not realized. You should thoroughly read this Quarterly Report with the understanding that our actual future results may be materially different from and worse than what we expect. Other sections of this Quarterly Report include additional factors that could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. Some important factors that could cause actual results to differ materially from those in the forward-looking statements are, in certain instances, included with such forward-looking statements and in “Risk Factors” in our 2012 Annual Report. Additionally, new risk factors and uncertainties emerge from time to time and it is not possible for our management to predict all risk factors and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of the forward-looking statements by these cautionary statements.
Readers are cautioned not to place undue reliance on the forward-looking statements contained in this Quarterly Report, which represent the best judgment of our management. Such statements, estimates and projections reflect various assumptions made by us concerning anticipated results, which are subject to business, economic and competitive uncertainties and contingencies, many of which are beyond our control and which may or may not prove to be correct. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

 Item 3 — Quantitative and Qualitative Disclosure about Market Risk
We are exposed to certain market risks arising from the use of financial instruments in the ordinary course of business. These risks arise primarily as a result of potential changes in the fair market value of financial instruments that would result from adverse fluctuations in interest rates and foreign currency exchange rates as discussed below. We have entered, and in the future may enter, into derivative financial instrument transactions to manage or reduce market risk, but we do not enter into derivative financial instrument transactions for speculative or trading purposes.
Interest Rate Risk . We are exposed to changes in interest rates through our variable rate long-term debt. We use interest rate swaps to manage our exposure to interest rate risks. Interest rate swaps are used to convert floating rate debt obligations to a fixed rate in order to achieve an overall desired position of fixed and floating rate debt. See Note 6 and Note 7 to the unaudited condensed consolidated financial statements. As of March 31, 2013, our net exposure to floating interest rate fluctuations on our outstanding debt was $17.1 million, based on floating rate debt of $1,403 million less the $1,385 million notional principal of our floating to fixed interest rate swaps. A 1% increase or decrease to the overall variable interest rate charged to us would thus increase or decrease our interest expense by approximately $0.1 million on an annual basis as of March 31, 2013.
Foreign Currency Exchange Rate Risk . We are exposed to foreign exchange risk associated with our international operations. For a discussion of our foreign exchange risk, see Item 11, “Quantitative and Qualitative Disclosures About Market Risk” in our 2012 Annual Report. There have been no material changes to these previously reported matters during the three months ended March 31, 2013.

 Item 1A — Risk Factors
Except as set forth below, information about material risks related to our business, financial condition and results of operations for the three months ended March 31, 2013 does not materially differ from that set out under Item 3, “Risk Factors” in our 2012 Annual Report. You should carefully consider the risk factors previously disclosed under Item 3, “Risk Factors” in our 2012 Annual Report, which could materially affect our business, financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.
We have been sued for patent infringement.
On April 16, 2013, Transocean filed a complaint against us alleging infringement of their dual activity patents. The patents in question are also the subject of pending actions in the United States against Maersk Drilling (“Maersk”) and Stena Drilling. Transocean sued Maersk for infringing two of Transocean’s U.S. patents involving dual activity on drilling assemblies. In April 2011, a jury determined that Maersk had not established that the asserted patent claims were invalid, that Maersk had infringed those claims, and awarded Transocean $15 million for Maersk’s infringement. On June 30, 2011, the judge presiding over the case entered a Final Judgment disregarding the jury award and entering judgment in Maersk’s favor, determining as a matter of law that the asserted patent claims were invalid for obviousness and lack of an enablement and that Maersk had not infringed. Transocean appealed this judgment and, in November 2012, prevailed on appeal. In January 2013, Maersk filed a petition for panel rehearing and rehearing en banc before the court of appeals. The motion was denied in February 2013. Maersk may now file a petition for certiorari with the U.S. Supreme Court. The Stena Drilling case has not yet gone to trial. If our lawsuit with Transocean is adversely determined, we could be forced to pay royalties to Transocean or make indemnity payments to our clients.
