DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. General Information

     The unaudited consolidated financial statements of Diamond Offshore Drilling, Inc. and subsidiaries, which we refer to as “Diamond Offshore,” “we,” “us” or “our,” should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2010 (File No. 1-13926).

     As of October 20, 2011, Loews Corporation, or Loews, owned 50.4% of the outstanding shares of our common stock.

Interim Financial Information

     The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S., or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, pursuant to such rules and regulations, they do not include all disclosures required by GAAP for complete financial statements. The consolidated financial information has not been audited but, in the opinion of management, includes all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation of the consolidated balance sheets, statements of operations and statements of cash flows at the dates and for the periods indicated. Results of operations for interim periods are not necessarily indicative of results of operations for the respective full years.

Use of Estimates in the Preparation of Financial Statements

     The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated.

Reclassifications

     Certain amounts applicable to the prior periods have been reclassified to conform to the classifications currently followed. Such reclassifications do not affect earnings.

Cash and Cash Equivalents, Marketable Securities

     We consider short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash to be cash equivalents. See Note 6.

     We classify our investments in marketable securities as available for sale, and they are stated at fair value in our Consolidated Balance Sheets. Accordingly, any unrealized gains and losses, net of taxes, are reported in our Consolidated Balance Sheets in “Accumulated other comprehensive gain” until realized. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity and such adjustments are included in our Consolidated Statements of Operations in “Interest income.” The sale and purchase of securities are recorded on the date of the trade. The cost of debt securities sold is based on the specific identification method. Realized gains or losses, as well as any declines in value that are judged to be other than temporary, are reported in our Consolidated Statements of Operations in “Other income (expense) — Other, net.”

     The effect of exchange rate changes on cash balances held in foreign currencies was not material for the nine months ended September 30, 2011 and 2010.

Provision for Bad Debts

     We record a provision for bad debts on a case-by-case basis when facts and circumstances indicate that a customer receivable may not be collectible. In establishing these reserves, we consider historical and other factors that predict collectability, including write-offs, recoveries and the monitoring of credit quality. Such provision is reported as a component of “Operating expenses” in our Consolidated Statements of Operations. See Note 2.

Derivative Financial Instruments

     Our derivative financial instruments consist of foreign currency forward exchange, or FOREX, contracts which we may designate as cash flow hedges. In accordance with GAAP, each derivative contract is stated in the balance sheet at its fair value with gains and losses reflected in the income statement except that, to the extent the derivative qualifies for and is designated as an accounting hedge, the gains and losses are reflected in income in the same period as offsetting gains and losses on the qualifying hedged positions. We report such realized gains and losses as a component of “Contract drilling, excluding depreciation” expense in our Consolidated Statements of Operations to offset the impact of foreign currency fluctuations in our expenditures in local foreign currencies in the countries in which we operate.

     Realized gains or losses upon settlement of derivative contracts not designated as cash flow hedges are reported as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations. For the three-month and nine-month periods ended September 30, 2011 and 2010, we recognized no foreign currency transaction gain (loss) attributable to FOREX contracts not designated as cash flow hedges. See Notes 5 and 6.

Capitalized Interest

     We capitalize interest cost for the construction and upgrade of qualifying assets. Commencing in August 2011, we began capitalizing interest on qualifying expenditures related to the construction of three drillships with expected deliveries in 2013 and 2014. There were no qualifying expenditures during the nine months ended September 30, 2010. See Note 7.

     A reconciliation of our total interest cost to “Interest expense” as reported in our Consolidated Statements of Operations is as follows:

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
		2011				2010				2011				2010
		(In thousands)
Total interest cost including amortization of debt issuance costs		$	20,364			$	22,567			$	64,634			$	66,221
Capitalized interest			(4,490	)			—				(4,490	)			—
Total interest expense as reported		$	15,874			$	22,567			$	60,144			$	66,221

Property, Plant and Equipment

     We carry our drilling and other property and equipment at cost. Maintenance and routine repairs are charged to income currently while replacements and betterments, which upgrade or increase the functionality of our existing equipment and that significantly extend the useful life of an existing asset, are capitalized. Significant judgments, assumptions and estimates may be required in determining whether or not such replacements and betterments meet the criteria for capitalization and in determining useful lives and salvage values of such assets. Changes in these judgments, assumptions and estimates could produce results that differ from those reported. Historically, the amount of capital additions requiring significant judgments, assumptions or estimates has not been significant. Depreciation is amortized up to applicable salvage values by applying the straight-line method over the remaining estimated useful lives. During the nine months ended September 30, 2011 and the year ended December 31, 2010, we capitalized $136.3 million and $379.8 million, respectively, in replacements and betterments of our drilling fleet, resulting from numerous projects ranging from $25,000 to $50 million per project.

     We evaluate our property and equipment for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable (such as cold stacking a rig or excess spending over budget on a new-build or major rig upgrade). We utilize a probability-weighted cash flow analysis in testing an asset for potential impairment. Our assumptions and estimates underlying this analysis include the following:

•

dayrate by rig;

	•		utilization rate by rig (expressed as the actual percentage of time per year that the rig would be used);
	•		the per day operating cost for each rig if active, ready-stacked or cold-stacked;
	•		the estimated annual cost for rig replacements and/or enhancement programs;
	•		the estimated maintenance, inspection or other costs associated with a rig returning to work;
	•		salvage value for each rig; and
	•		estimated proceeds that may be received on disposition of the rig.

     Based on these assumptions and estimates, we develop a matrix using several different utilization/dayrate scenarios, to each of which we have assigned a probability of occurrence. The sum of our utilization scenarios (which include active, warm stacked and cold stacked) and probability of occurrence scenarios both equal 100% in the aggregate. We reevaluate our cold-stacked rigs annually, and we update the matrices for each of our cold stacked rigs at each year end and modify our assumptions giving consideration to the length of time the rig has been cold stacked, the current and expected market for the type of rig and expectations of future oil and gas prices. Further, to test sensitivity, we consider the impact of a 5% reduction in assumed dayrates for the cold-stacked rigs (holding all other assumptions and estimates in the model constant). We would not necessarily record an impairment if the sensitivity analysis indicated potential cash flows would be insufficient to recover our carrying value. We would assess other qualitative factors including industry, regulatory and other relevant conditions to determine whether an impairment or further disclosure is warranted.

     As of September 30, 2011, we had eight cold stacked rigs with an aggregate net book value of approximately $87.6 million. Of our cold stacked rigs, four were jack-up rigs, consisting of three mat-supported rigs and one independent-leg, cantilevered rig (all in the U.S. Gulf of Mexico, or GOM), and four were intermediate semisubmersible rigs (two in the GOM and two in Malaysia), including the Ocean Epoch, which was cold stacked in the first quarter of 2011. As of December 31, 2010, we had seven cold stacked rigs with an aggregate net book value of approximately $78.0 million. We performed an impairment review for each of these rigs using the methodology described above. Based on our analyses, we have concluded that these rigs were not subject to impairment at September 30, 2011 and December 31, 2010, respectively.

     Management’s assumptions are an inherent part of our asset impairment evaluation and the use of different assumptions could produce results that differ from those reported.

Comprehensive Income

     A reconciliation of net income to comprehensive income is as follows:

		Three Months Ended								Nine Months Ended
		September 30,								September 30,
		2011				2010				2011				2010
		(In thousands)
Net income		$	256,854			$	198,524			$	774,052			$	713,770
Other comprehensive gains (losses), net of tax:

Unrealized holding (loss) gain			(11,221	)			3,608				(3,538	)			348
Reclassification adjustment for loss (gain) included in net income			(3,115	)			(116	)			(8,064	)			(845	)

Comprehensive income		$	242,464			$	202,020			$	762,018			$	713,256

Foreign Currency

     Our functional currency is the U.S. dollar. Foreign currency transaction gains and losses are reported as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations. For the three-month and nine-month periods ended September 30, 2011, we recognized net foreign currency transaction (losses) of $(1.4) million and $(4.6) million, respectively. For the three-month and nine-month periods ended September 30, 2010, we recognized net foreign currency transaction gains of $3.7 million and $0.2 million, respectively. See Note 5.

Revenue Recognition

     Revenue from our dayrate drilling contracts is recognized as services are performed. In connection with such drilling contracts, we may receive fees (either lump-sum or dayrate) for the mobilization of equipment. These fees are earned as services are performed over the initial term of the related drilling contracts. We defer mobilization fees received, as well as direct and incremental mobilization costs incurred, and amortize each, on a straight line basis, over the term of the related drilling contracts (which is the period we estimate to be benefited from the mobilization activity). Straight line amortization of mobilization revenues and related costs over the initial term of the related drilling contracts (which generally range from 2 to 60 months) is consistent with the timing of net cash flows generated from the actual drilling services performed. Absent a contract, mobilization costs are recognized as incurred.

     From time to time, we may receive fees from our customers for capital improvements to our rigs (either lump-sum or dayrate). We defer such fees received in “Accrued liabilities” and “Other liabilities” in our Consolidated Balance Sheets and recognize these fees into income on a straight-line basis over the period of the related drilling contract. We capitalize the costs of such capital improvements and depreciate them over the estimated useful life of the asset.

     We record reimbursements received for the purchase of supplies, equipment, personnel services and other services provided at the request of our customers in accordance with a contract or agreement, for the gross amount billed to the customer, as “Revenues related to reimbursable expenses” in our Consolidated Statements of Operations.

Income Taxes

     Certain of our international rigs are owned and operated, directly or indirectly, by Diamond Offshore International Limited, or DOIL, a Cayman Islands subsidiary which we wholly own. Since forming this subsidiary in 2002, it has been our intention to indefinitely reinvest the earnings of the subsidiary to finance foreign activities. Consequently, no U.S. federal income taxes have been provided on these earnings except to the extent that such earnings were immediately subject to U.S. federal income taxes and except for the earnings of Diamond East Asia Limited, or DEAL, a wholly-owned subsidiary of DOIL. It had been our intention to repatriate the earnings of DEAL to the U.S. and, accordingly, we provided U.S. income taxes on its earnings. However, a tax law provision that expired at the end of 2009, but was subsequently signed back into law by the President of the United States on December 17, 2010, in conjunction with our decisions in late 2010 and the first half of 2011 to build three new drillships overseas, caused us to reassess our intent to repatriate the earnings of DEAL to the U.S. We now plan to reinvest the earnings of DEAL internationally through another of our foreign companies, and consequently, we are no longer providing U.S. income taxes on its earnings. During the nine months ended September 30, 2011, we reversed approximately $15.0 million of U.S. income taxes that had been provided in prior periods for the earnings of DEAL.

Recently Issued Accounting Pronouncements

     In June 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income,” or ASU 2011-05, which eliminates the option to present components of other comprehensive income, or OCI, as part of the statement of changes in stockholders’ equity, requires the presentation of each component of net income and each component of OCI either in a single continuous statement or in two separate but consecutive statements and also requires presentation of reclassification adjustments on the face of the financial statement. ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011; however, early adoption is permitted. The adoption of ASU 2011-05 will not have an effect on our financial position, results of operations or cash flows.

     In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” or ASU 2011-04. ASU 2011-04 clarifies existing fair value measurement and disclosure requirements, amends certain fair value measurement principles and requires additional disclosures about fair value measurements. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. We will incorporate any additional disclosures in our annual financial statements for the year ending December 31, 2012.

Recoveries during the first nine months of 2011 included $8.5 million in final payments from a previous customer in the North Sea and $2.6 million from another customer in Egypt for whom we no longer work. In addition, during 2011, we offset $18.4 million in previously reserved trade receivables against the allowance for bad debts as we had exhausted all methods of recovery against the North Sea customer.

     During the three-month and nine-month periods ended September 30, 2010, we recovered $2.0 million and $5.9 million, respectively, in previously reserved bad debts. Recoveries during the first nine months of 2010 included $1.0 million from a previous customer in the North Sea and $4.9 million from a previous customer in Egypt. No allowances were deemed necessary for the three-month and nine-month periods ended September 30, 2010.

5. Derivative Financial Instruments

Foreign Currency Forward Exchange Contracts

     Our international operations expose us to foreign exchange risk associated with our costs payable in foreign currencies for employee compensation, foreign income tax payments and purchases from foreign suppliers. We may utilize FOREX contracts to manage our foreign exchange risk. Our FOREX contracts may obligate us to exchange predetermined amounts of foreign currencies on specified dates or to net settle the spread between the contracted foreign currency exchange rate and the spot rate on the contract settlement date, which, for most of our contracts, is the average spot rate for the contract period.

     We enter into FOREX contracts when we believe market conditions are favorable to purchase contracts for future settlement with the expectation that such contracts, when settled, will reduce our exposure to foreign currency gains/losses on foreign currency expenditures in the future. The amount and duration of such contracts is based on our monthly forecast of expenditures in the significant currencies in which we do business and for which there is a financial market (i.e., Australian dollars, Brazilian reais, British pounds sterling, Mexican pesos and Norwegian kroner). These forward contracts are derivatives as defined by GAAP.

     We have adopted a hedging strategy whereby certain of our qualifying FOREX contracts are designated as cash flow hedges based on our expected future foreign currency requirements. These hedges are expected to be highly effective, and therefore, adjustments to record the carrying value of the effective portion of our derivative financial instruments to their fair value are recorded as a component of “Accumulated other comprehensive gain (loss),” or AOCGL, in our Consolidated Financial Statements. The effective portion of the cash flow hedge will remain in AOCGL until it is reclassified into earnings in the period or periods during which the hedged transaction affects earnings or it is determined that the hedged transaction will not occur. Adjustments to record the carrying value of

the ineffective portion of our derivative financial instruments to fair value are recorded as “Foreign currency transaction gain (loss)” in our Consolidated Statements of Operations.

     During the nine months ended September 30, 2011 and 2010, we settled FOREX contracts with an aggregate notional value of approximately $224.8 million and $251.1 million, respectively, all of which were designated as accounting hedges. During the nine-month periods ended September 30, 2011 and 2010, we did not enter into or settle any FOREX contracts that were not designated as accounting hedges.

     The following table presents the amounts recognized in our Consolidated Statements of Operations related to our FOREX contracts designated as accounting hedges for the three-month and nine-month periods ended September 30, 2011 and 2010.

     As of September 30, 2011, we had FOREX contracts outstanding in the aggregate notional amount of $191.0 million, consisting of $30.7 million in Australian dollars, $102.9 million in Brazilian reais, $33.6 million in British pounds sterling, $10.9 million in Mexican pesos and $12.9 million in Norwegian kroner. These contracts generally settle monthly through March 2012. As of September 30, 2011, all outstanding derivative contracts had been designated as cash flow hedges. See Note 6.

     The following table presents the fair values of our derivative FOREX contracts designated as hedging instruments at September 30, 2011 and December 31, 2010.

     As of September 30, 2011, the estimated amount of net unrealized gains associated with our FOREX contracts that will be reclassified to earnings during the next twelve months was $13.6 million. The net unrealized gains associated with these derivative financial instruments will be reclassified to contract drilling expense.

6. Financial Instruments and Fair Value Disclosures

Concentrations of Credit and Market Risk

     Financial instruments which potentially subject us to significant concentrations of credit or market risk consist primarily of periodic temporary investments of excess cash, trade accounts receivable and investments in debt securities, including residential mortgage-backed securities. We place our excess cash investments in high quality short-term money market instruments through several financial institutions. At times, such investments may be in excess of the insurable limit. We periodically evaluate the relative credit standing of these financial institutions as part of our investment strategy.

     Most of our investments in debt securities are U.S. government securities with minimal credit risk. However, we are exposed to market risk due to price volatility associated with interest rate fluctuations.

     Concentrations of credit risk with respect to our trade accounts receivable are limited primarily due to the entities comprising our customer base. Since the market for our services is the offshore oil and gas industry, this customer base consists primarily of major and independent oil and gas companies and government-owned oil companies. Our two customers in Brazil, Petróleo Brasileiro S.A. (a Brazilian multinational energy company that is majority-owned by the Brazilian government) and OGX Petróleo e Gás Ltda. (a privately owned Brazilian oil and natural gas company), accounted for $143.6 million and $62.4 million, or 23% and 10%, respectively, of our total consolidated gross trade accounts receivable balances as of September 30, 2011, and $180.8 million and $52.4 million, or 29% and 8%, respectively, as of December 31, 2010.

     In general, before working for a customer with whom we have not had a prior business relationship and/or whose financial stability may be uncertain to us, we perform a credit review on that company. Based on that analysis, we may require that the customer present a letter of credit, prepay or provide other credit enhancements. Historically, we have not experienced significant losses on our trade receivables. We record a provision for bad debts on a case-by-case basis when facts and circumstances indicate that a customer receivable may not be collectible. Our allowance for bad debts was $8.2 million and $31.9 million at September 30, 2011 and December 31, 2010, respectively. See Note 2.

     One of our drilling contracts obligates our customer to pay us, over the term of the drilling program, an aggregate drilling rate of $560,000 per day, consisting of $75,000 per day payable in accordance with our normal credit terms (due 30 days after receipt of invoice) and the remainder of the contractual dayrate, $485,000 per day, payable through the conveyance of a 27% net profits interest, or NPI, in certain developmental oil-and-gas producing properties.

     At September 30, 2011, $102.7 million was payable to us from the NPI. Based on current production payout estimates, we expect to collect the entire $102.7 million receivable within the next twelve months and have presented this amount in “Accounts receivable, net of allowance for bad debts” in our Consolidated Balance Sheets. At September 30, 2011, we believe that collectability of the amount owed pursuant to the NPI arrangement was reasonably assured.

     At December 31, 2010, $85.0 million was payable to us from the NPI, of which $49.6 million and $35.4 million are presented as “Accounts receivable, net of allowance for bad debts” and “Long-term receivable,” respectively, in our Consolidated Balance Sheets.

Fair Values

     The amounts reported in our Consolidated Balance Sheets for cash and cash equivalents, marketable securities, accounts receivable, forward exchange contracts and accounts payable approximate fair value. Fair values and related carrying values of our debt instruments are shown below.

		September 30, 2011								December 31, 2010
		Fair Value				Carrying Value				Fair Value				Carrying Value
						(In millions)
4.875% Senior Notes		$	276.3			$	249.8			$	270.0			$	249.7
5.15% Senior Notes			272.8				249.8				271.1				249.7
5.70% Senior Notes			540.7				496.8				493.1				496.8
5.875% Senior Notes			579.2				499.4				550.9				499.4

     We have estimated the fair value amounts by using appropriate valuation methodologies and information available to management as of September 30, 2011 and December 31, 2010, respectively. Considerable judgment is required in developing these estimates, and accordingly, no assurance can be given that the estimated values are indicative of the amounts that would be realized in a free market exchange. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it was practicable to estimate that value:

	•		Cash and cash equivalents — The carrying amounts approximate fair value because of the short maturity of these instruments.
	•		Marketable securities — The fair values of the debt securities, including residential mortgage-backed securities, available for sale were based on the quoted closing market prices on September 30, 2011 and December 31, 2010, respectively.
	•		Accounts receivable and accounts payable — The carrying amounts approximate fair value based on the nature of the instruments.
	•		Forward exchange contracts — The fair value of our FOREX contracts is based on both quoted market prices and valuations derived from pricing models on September 30, 2011 and December 31, 2010, respectively.
	•		Long-term receivable — The carrying amount approximates fair value based on the nature of the instrument.
	•		Long-term debt — The fair value of our 5.70% Senior Notes due 2039, 5.875% Senior Notes due 2019, 4.875% Senior Notes due July 1, 2015, and 5.15% Senior Notes due September 1, 2014 is based on the quoted market prices from brokers of these instruments.

     Certain of our assets and liabilities are required to be measured at fair value in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy prescribed by GAAP requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1		Quoted prices for identical instruments in active markets. Level 1 assets include short-term investments such as money market funds, U.S. Treasury Bills and Treasury notes. Our Level 1 assets at September 30, 2011 consisted of cash held in money market funds of $327.2 million and investments in U.S. Treasury securities of $801.5 million. Our Level 1 assets at December 31, 2010 consisted of cash held in money market funds of $442.2 million and investments in U.S. Treasury Bills of $600.0 million.

Level 2		Quoted market prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 assets and liabilities include residential mortgage-backed securities and over-the-counter FOREX contracts. Our residential mortgage-backed securities were valued using a model-derived valuation technique based on the quoted closing market prices received from a financial institution. Our FOREX contracts are valued based on quoted market prices, which are derived from observable inputs including current spot and forward rates, less the contract rate multiplied by the notional amount. The inputs used in our valuation are obtained from a Bloomberg curve analysis which uses par coupon swap rates to calculate implied forward rates so that projected floating rate cash flows can be calculated. The valuation techniques underlying the models are widely accepted in the financial services industry and do not involve significant judgment.

Level 3		Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Level 3 assets and liabilities generally include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation or for which there is a lack of transparency as to the inputs used.

     Market conditions could cause an instrument to be reclassified among Levels 1, 2 and 3. Our policy regarding fair value measurements of financial instruments transferred into and out of levels is to reflect the transfers as having occurred at the beginning of the reporting period.

     Assets and liabilities measured at fair value on a recurring basis are summarized below:

     On October 12, 2011, we terminated our $285 million syndicated, senior unsecured revolving credit facility.

9. Commitments and Contingencies

     Various claims have been filed against us in the ordinary course of business, including claims by offshore workers alleging personal injuries. We have assessed each claim or exposure to determine the likelihood that the resolution of the matter might ultimately result in an adverse effect on our financial condition, results of operations and cash flows. When we determine that an unfavorable resolution of a matter is probable and such amount of loss can be determined, we record a reserve for the estimated loss at the time that both of these criteria are met. Our management believes that we have established adequate reserves for any liabilities that may reasonably be expected to result from these claims.

     Litigation. We are one of several unrelated defendants in 30 lawsuits filed in Louisiana and Mississippi state courts alleging that defendants manufactured, distributed or utilized drilling mud containing asbestos and, in our case, allowed such drilling mud to have been utilized aboard our offshore drilling rigs. The plaintiffs seek, among other things, an award of unspecified compensatory and punitive damages. The manufacture and use of asbestos-

containing drilling mud had already ceased before we acquired any of the drilling rigs addressed in these lawsuits. We believe that we are not liable for the damages asserted and we expect to receive complete defense and indemnity with respect to a majority of the lawsuits from Murphy Exploration & Production Company pursuant to the terms of our 1992 asset purchase agreement with them. We also believe that we are not liable for the damages asserted in the remaining lawsuits pursuant to the terms of our 1989 asset purchase agreement with Diamond M Corporation, and we have filed a declaratory judgment action in Texas state court against NuStar Energy LP, the successor to Diamond M Corporation, seeking a judicial determination that we did not assume liability for these claims. We are unable to estimate our potential exposure, if any, to these lawsuits at this time but do not believe that ultimate liability, if any, resulting from this litigation will have a material adverse effect on our financial condition, results of operations and cash flows.

     Various other claims have been filed against us in the ordinary course of business. In the opinion of our management, no pending or known threatened claims, actions or proceedings against us are expected to have a material adverse effect on our consolidated financial position, results of operations and cash flows.

     We intend to defend these matters vigorously; however, we cannot predict with certainty the outcome or effect of any litigation matters specifically described above or any other pending litigation or claims. There can be no assurance as to the ultimate outcome of these lawsuits.

     Personal Injury Claims. Our deductibles for marine liability coverage, including personal injury claims, which primarily result from Jones Act liability in the Gulf of Mexico, are currently $10.0 million per the first occurrence, with no aggregate deductible, and vary in amounts ranging between $5.0 million and, if aggregate claims exceed certain thresholds, up to $100.0 million for each subsequent occurrence, depending on the nature, severity and frequency of claims which might arise during the policy year. The Jones Act is a federal law that permits seamen to seek compensation for certain injuries during the course of their employment on a vessel and governs the liability of vessel operators and marine employers for the work-related injury or death of an employee. We engage outside consultants to assist us in estimating our aggregate reserve for personal injury claims based on our historical losses and utilizing various actuarial models. We allocate a portion of the aggregate reserve to “Accrued liabilities” based on an estimate of claims expected to be paid within the next twelve months with the residual recorded as “Other liabilities.” At September 30, 2011, our estimated liability for personal injury claims was $36.2 million, of which $8.4 million and $27.8 million were recorded in “Accrued liabilities” and “Other liabilities,” respectively, in our Consolidated Balance Sheets. At December 31, 2010, our estimated liability for personal injury claims was $35.0 million, of which $11.1 million and $23.9 million were recorded in “Accrued liabilities” and “Other liabilities,” respectively, in our Consolidated Balance Sheets. The eventual settlement or adjudication of these claims could differ materially from our estimated amounts due to uncertainties such as:

	•		the severity of personal injuries claimed;
	•		significant changes in the volume of personal injury claims;
	•		the unpredictability of legal jurisdictions where the claims will ultimately be litigated;
	•		inconsistent court decisions; and
	•		the risks and lack of predictability inherent in personal injury litigation.

     Purchase Obligations. Since December 2010, we have entered into three separate turnkey contracts with Hyundai for the construction of three dynamically positioned, ultra-deepwater drillships, with deliveries scheduled for late in the second and fourth quarters of 2013 and in the second quarter of 2014. The aggregate cost of the three drillships, including commissioning, spares and project management, is expected to be approximately $1.8 billion.

     The contracted price of each drillship is payable in two installments. The first installments, aggregating $478.3 million, were paid in the first and second quarters of 2011 and are reported in “Drilling and other property and equipment, net of accumulated depreciation” in our Consolidated Balance Sheets as construction work-in-progress. At September 30, 2011 and December 31, 2010, we had no other purchase obligations for major rig upgrades or any other significant obligations, except for those related to our direct rig operations, which arise during the normal course of business.

     Letters of Credit and Other. We were contingently liable as of September 30, 2011 in the amount of $65.1 million under certain performance, bid, supersedeas, tax appeal and custom bonds and letters of credit. At September 30, 2011, two of our outstanding bonds, totaling $19.6 million, had been purchased from a related party after obtaining competitive quotes. Agreements relating to approximately $51.6 million of performance bonds can require collateral at any time. As of September 30, 2011, we had not been required to make any collateral deposits with respect to these agreements. The remaining agreements cannot require collateral except in events of default. On our behalf, banks have issued letters of credit securing certain of these bonds.

10. Segments and Geographic Area Analysis

     Although we provide contract drilling services with different types of offshore drilling rigs and also provide such services in many geographic locations, we have aggregated these operations into one reportable segment based on the similarity of economic characteristics among all divisions and locations, including the nature of services provided and the type of customers of such services, in accordance with FASB Accounting Standards Codification Topic 280, Segment Reporting.

ITEM 2.		Management’s Discussion and Analysis of Financial Condition and Results of Operations.

     The following discussion should be read in conjunction with our unaudited consolidated financial statements (including the notes thereto) included elsewhere in this report and our audited consolidated financial statements and the notes thereto, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 1A, “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2010. References to “Diamond Offshore,” “we,” “us” or “our” mean Diamond Offshore Drilling, Inc., a Delaware corporation, and its subsidiaries.

     We provide contract drilling services to the energy industry around the globe and are a leader in offshore drilling. Our current fleet of 46 offshore drilling rigs consists of 32 semisubmersibles, 13 jack-ups and one drillship. We currently have three drillships on order. The Ocean BlackHawk and Ocean BlackHornet are expected to be delivered late in the second and fourth quarters of 2013, respectively. The third drillship, the Ocean BlackRhino, is expected to be delivered at the end of the second quarter of 2014.

     Of our fleet, eight rigs are currently cold stacked, consisting of four intermediate semisubmersibles (two in the U.S. Gulf of Mexico, or GOM, and two in Malaysia) and four jack-up rigs (all in the GOM). We are preparing to stack an additional jack-up rig, the Ocean Sovereign, in the fourth quarter of 2011.

Overview

Industry Conditions

     U.S. Gulf of Mexico — The drilling moratorium in the GOM was lifted in the fourth quarter of 2010; however, the return of deepwater drilling activity to pre-Macondo levels has been hampered by the continued slow issuance of oil and gas drilling permits despite improvements in the permit application process. Absent an increase in permitting activity, weakness in the GOM market is likely to continue throughout the remainder of 2011 and into 2012, with the possibility of additional rigs being cold stacked by us and others in the industry, as well as rigs leaving the GOM for international opportunities. We are unable to predict when or if the pace of permitting in the GOM will return to pre-Macondo levels.

     Since the Macondo well blowout, new rules for oil and gas operations on the Outer Continental Shelf have been implemented, including new standards for well design, casing and cementing and well control procedures, as well as rules requiring operators to systematically identify risks and establish safeguards against those risks through a comprehensive safety and environmental management system, or SEMS. New regulations continue to be announced, including recently proposed rules regarding employee training, engaging personnel in safety management and requiring third party audits of SEMS programs.

Our Fleet

     As of the date of this report, we are actively marketing three rigs in the GOM market, consisting of two semisubmersible rigs and one jack-up rig. Given the ongoing uncertainty with respect to drilling activity in the GOM, we are continuing to actively seek international opportunities to employ our rigs outside the GOM. However, we can provide no assurance that we will be successful in our efforts to employ our remaining impacted rigs in the GOM or elsewhere in the near term.

     As of October 17, 2011, our contract backlog was approximately $8.1 billion, of which our contracts in the GOM and Brazil represented approximately $2.0 billion, or 25%, and $4.6 billion, or 56%, respectively.

     Floaters

     Our intermediate and high-specification floater rigs, both domestic and international, accounted for approximately 95% of our contract drilling revenue during the third quarter of 2011. This market remains stable with industry floater utilization reportedly nearing 90%. Approximately 84% of the time for our intermediate and high-specification floater rigs is committed for the remainder of 2011. Additionally, 61% of the time on our floating rigs is committed in 2012.

     Jack-ups

     As a result of a recent increase in tender activity in the Mexican Gulf of Mexico, we received new term contracts, totaling 3.8 years and $163.0 million, on two jack-up units previously working offshore in the GOM and in Brazil, the Ocean Titan and Ocean Scepter, respectively. These rigs are scheduled to commence operations in the fourth quarter of 2011 and the first quarter of 2012, respectively. Additional tendering activity is ongoing.

Contract Drilling Backlog

     The following table reflects our contract drilling backlog as of October 17, 2011, February 1, 2011 (the date reported in our Annual Report on Form 10-K for the year ended December 31, 2010) and October 18, 2010 (the date reported in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2010). Contract drilling backlog is calculated by multiplying the contracted operating dayrate by the firm contract period and adding one-half of any potential rig performance bonuses. Our calculation also assumes full utilization of our drilling equipment for the contract period (excluding scheduled shipyard and survey days); however, the amount of actual revenue earned and the actual periods during which revenues are earned will be different than the amounts and periods shown in the tables below due to various factors. Utilization rates, which generally approach 95-98% during contracted periods, can be adversely impacted by downtime due to various operating factors including, but not limited to, weather conditions and unscheduled repairs and maintenance. Contract drilling backlog excludes revenues for mobilization, demobilization, contract preparation and customer reimbursables. No revenue is generally earned during periods of downtime for regulatory surveys. Changes in our contract drilling backlog between periods are a function of the performance of work on term contracts, as well as the extension or modification of existing term contracts and the execution of additional contracts.

General

     The two most significant variables affecting our revenues are dayrates for rigs and rig utilization rates, each of which is a function of rig supply and demand in the marketplace. Demand for drilling services is dependent upon the level of expenditures set by oil and gas companies for offshore exploration and development, as well as a variety of political, regulatory and economic factors. The availability of rigs in a particular geographical region also affects both dayrates and utilization rates. These factors are not within our control and are difficult to predict.

     Demand affects the number of days our fleet is utilized and the dayrates earned. As utilization rates increase, dayrates tend to increase as well, reflecting the lower supply of available rigs. Conversely, as utilization rates decrease, dayrates tend to decrease as well, reflecting the excess supply of rigs. When a rig is idle, no dayrate is earned and revenues will decrease as a result. Revenues can also be affected as a result of the acquisition or disposal of rigs, required surveys and shipyard upgrades. In order to improve utilization or realize higher dayrates, we may mobilize our rigs from one market to another. However, during periods of mobilization, revenues may be adversely affected. As a response to changes in demand, we may withdraw a rig from the market by stacking it or may reactivate a rig stacked previously, which may decrease or increase revenues, respectively.

     Operating Income. Our operating income is primarily affected by revenue factors, but is also a function of varying levels of operating expenses. Our operating expenses represent all direct and indirect costs associated with the operation and maintenance of our drilling equipment. The principal components of our operating costs are,

among other things, direct and indirect costs of labor and benefits, repairs and maintenance, freight, regulatory inspections, boat and helicopter rentals and insurance. Labor and repair and maintenance costs represent the most significant components of our operating expenses. In general, our labor costs increase primarily due to higher salary levels, rig staffing requirements and costs associated with labor regulations in the geographic regions in which our rigs operate. Costs to repair and maintain our equipment fluctuate depending upon the type of activity the drilling unit is performing, as well as the age and condition of the equipment and the regions in which our rigs are working.

     Our operating income is negatively impacted when we perform certain regulatory inspections, which we refer to as a 5-year survey, or special survey, that are due every five years for each of our rigs. Operating revenue decreases because these special surveys are performed during scheduled downtime in a shipyard. Operating expenses increase as a result of these special surveys due to the cost to mobilize the rigs to a shipyard, inspection costs incurred and repair and maintenance costs. Repair and maintenance activities may result from the special survey or may have been previously planned to take place during this mandatory downtime. The number of rigs undergoing a 5-year survey will vary from year to year, as well as from quarter to quarter.

     In addition, operating income may be negatively impacted by intermediate surveys, which are performed at interim periods between 5-year surveys. Intermediate surveys are generally less extensive in duration and scope than a 5-year survey. Although an intermediate survey may require some downtime for the drilling rig, it normally does not require dry-docking or shipyard time, except for rigs located in the United Kingdom, or U.K., and Norwegian sectors of the North Sea.

     During the remainder of 2011, five of our rigs will require or complete 5-year surveys, and we expect that they will be out of service for approximately 120 rig days in the aggregate. We also expect to spend an additional approximately 430 rig days during 2011 for intermediate surveys, the mobilization of rigs, contract preparation activities and extended maintenance projects. We can provide no assurance as to the exact timing and/or duration of downtime associated with regulatory inspections, planned rig mobilizations and other shipyard projects. Fluctuations between periods in the number of surveys performed and the amount of downtime associated with those surveys could have a material impact on our results of operations. See “ — Overview — Contract Drilling Backlog.”

     We renewed our principal insurance policies effective May 1, 2011. Our coverage and policy limits for both physical damage and marine liability insurance are substantially similar to those of our previous policies. We believe that our current policy limit for our marine liability insurance is within the range that is customary for companies of our size in the offshore drilling industry and at levels appropriate for our business.

     Under our protection and indemnity policy, which expires on May 1, 2012, we carry marine liability insurance covering certain legal liabilities, including coverage for certain personal injury claims, with no exclusions for pollution and/or environmental risk. Our deductibles for marine liability coverage, including for personal injury claims, are $10.0 million for the first occurrence and vary in amounts ranging between $5.0 million and, if aggregate claims exceed certain thresholds, up to $100.0 million for each subsequent occurrence, depending on the nature, severity and frequency of claims which might arise during the policy year, which under our current policy commenced on May 1, 2011.

     We are self-insured for physical damage to rigs and equipment caused by named windstorms in the U.S. Gulf of Mexico. If a named windstorm in the U.S. Gulf of Mexico causes significant damage to our rigs or equipment, it could have a material adverse effect on our financial position, results of operations and cash flows. However, under our insurance policy that expires on May 1, 2012, we carry physical damage insurance for certain losses other than those caused by named windstorms in the U.S. Gulf of Mexico for which our deductible for physical damage is $25.0 million per occurrence. We do not typically retain loss-of-hire insurance policies to cover our rigs.

Critical Accounting Estimates

     Our significant accounting policies are discussed in Note 1 of our notes to unaudited consolidated financial statements included in Item 1 of Part I of this report and in Note 1 of our notes to audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2010. There were no material changes to these policies during the nine months ended September 30, 2011 except that we no longer expect to repatriate the earnings of Diamond East Asia Limited, or DEAL, to the U.S. Accordingly, we are no longer providing U.S. income taxes on its earnings and have reversed U.S. income taxes on its earnings provided in previous years. For further discussion, see Note 1 “General Information” to our Consolidated Financial Statements in Item 1 of Part I of this report.

Results of Operations

     Although we perform contract drilling services with different types of drilling rigs and in many geographic locations, there is a similarity of economic characteristics among all our divisions and locations, including the nature of services provided and the type of customers for our services. We believe that the combination of our drilling rigs into one reportable segment is the appropriate aggregation in accordance with applicable accounting standards on segment reporting. However, for purposes of this discussion and analysis of our results of operations, we provide greater detail with respect to the types of rigs in our fleet and the geographic regions in which they operate to enhance the reader’s understanding of our financial condition, changes in financial condition and results of operations.
