General Information | 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, 2015 (File No. 1-13926). As of October 26, 2016, Loews Corporation owned approximately 53% 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 of normal recurring accruals) necessary for a fair presentation of Diamond Offshore’s consolidated balance sheets, statements of operations, statements of comprehensive income 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. Assets Held For Sale At December 31, 2015, we reported the $14.2 million carrying value of five marketed-for-sale jack-up rigs as “Assets held for sale” in our Consolidated Balance Sheets. One of these rigs was sold for $8.0 million in February 2016. At September 30, 2016, we reported “Assets held for sale” of $7.6 million in our Consolidated Balance Sheets, consisting of $6.2 million for our four marketed-for-sale jack-up rigs and $1.4 million for two of our semisubmersible rigs, which we expect to sell as scrap in the fourth quarter of 2016. Drilling and Other Property and Equipment We carry our drilling and other property and equipment at cost, less accumulated depreciation. Maintenance and routine repairs are charged to income currently while replacements and betterments that upgrade or increase the functionality of our existing equipment and that significantly extend the useful life of an existing asset are capitalized. During the nine-month period ended September 30, 2016 and the year ended December 31, 2015, we capitalized $154.8 million and $262.4 million, respectively, in replacements and betterments of our drilling fleet. See Notes 2 and 8. Capitalized Interest We capitalize interest cost for qualifying construction and upgrade projects. See Note 8. A reconciliation of our total interest cost to “Interest expense, net of amounts capitalized” as reported in our Consolidated Statements of Operations is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands) Total interest cost, including amortization of debt issuance costs $ 27,016 $ 23,830 $ 83,888 $ 84,254 Capitalized interest (7,984 ) (2,480 ) (15,184 ) (13,454 ) Total interest expense as reported $ 19,032 $ 21,350 $ 68,704 $ 70,800 Impairment of Long-Lived Assets 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, but not limited to, cold stacking a rig, the expectation of cold stacking a rig in the near term, contracted backlog of less than one year for a rig, a decision to retire or scrap a rig, or excess spending over budget on a newbuild, construction project or major rig upgrade). We utilize an undiscounted 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 if active, warm stacked or cold stacked (expressed as the actual percentage of time per year that the rig would be used at certain dayrates); • the per day operating cost for each rig if active, warm stacked or cold stacked; • the estimated annual cost for rig replacements and/or enhancement programs; • the estimated maintenance, inspection or other reactivation costs associated with a rig returning to work; • salvage value for each rig; and • estimated proceeds that may be received on disposition of each rig. Based on these assumptions, we develop a matrix for each rig under evaluation using multiple utilization/dayrate scenarios, to each of which we have assigned a probability of occurrence. We arrive at a projected probability- weighted cash flow for each rig based on the respective matrix and compare such amount to the carrying value of the asset to assess recoverability. The underlying assumptions and assigned probabilities of occurrence for utilization and dayrate scenarios are developed using a methodology that examines historical data for each rig, which considers the rig’s age, rated water depth and other attributes, and then assesses the rig’s future marketability in light of the current and projected market environment at the time of assessment. Other assumptions, such as operating, maintenance, inspection and reactivation costs, are estimated using historical data adjusted for known developments, cost projections for re-entry of rigs into the market and future events that are anticipated by management at the time of the assessment. Management’s assumptions are necessarily subjective and are an inherent part of our asset impairment evaluation, and the use of different assumptions could produce results that differ from those reported. Our methodology generally involves the use of significant unobservable inputs, representative of a Level 3 fair value measurement, which may include assumptions related to future dayrate revenue, costs and rig utilization, quotes from rig brokers, the long-term future performance of our rigs and future market conditions. Management’s assumptions involve uncertainties about future demand for our services, dayrates, expenses and other future events, and management’s expectations may not be indicative of future outcomes. Significant unanticipated changes to these assumptions could materially alter our analysis in testing an asset for potential impairment. For example, changes in market conditions that exist at the measurement date or that are projected by management could affect our key assumptions. Other events or circumstances that could affect our assumptions may include, but are not limited to, a further sustained decline in oil and gas prices, cancelations of our drilling contracts or contracts of our competitors, contract modifications, costs to comply with new governmental regulations, growth in the global oversupply of oil and geopolitical events, such as lifting sanctions on oil-producing nations. Should actual market conditions in the future vary significantly from market conditions used in our projections, our assessment of impairment would likely be different. See Note 2. Debt Issuance Costs Historically, we have presented deferred costs associated with the issuance of long-term debt as “Other Assets” in our unaudited consolidated balance sheets and have amortized such costs over the respective terms of the related debt. In April 2015, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30); Simplifying the Presentation of Debt Issuance Costs Other Assets Long-term (In thousands) Amount as previously presented, before adoption of ASU 2015-03 $ 116,480 $ 1,994,773 Deferred debt issuance costs (14,995 ) (14,995 ) Amount as restated, after adoption of ASU 2015-03 $ 101,485 $ 1,979,778 Recent Accounting Pronouncements In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ASU 2016-15 In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ASU 2016-02, ASU 2014-09.
