Interim Financial Information	Sep. 30, 2020
Accounting Policies [Abstract]
Interim Financial Information	Interim Financial Information These unaudited consolidated financial statements include the accounts of ICD and its subsidiary, and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). These consolidated financial statements should be read along with our audited consolidated financial statements for the year ended December 31, 2019, included in our Annual Report on Form 10-K for the year ended December 31, 2019. In management’s opinion, these financial statements contain all adjustments necessary to fairly present our financial position, results of operations, cash flows and changes in stockholders’ equity for all periods presented. As we had no items of other comprehensive income in any period presented, no other components of comprehensive income is presented. Interim results for the three and nine months ended September 30, 2020 may not be indicative of results that will be realized for the full year ending December 31, 2020. Segment and Geographical Information Our operations consist of one reportable segment because all of our drilling operations are located in the United States and have similar economic characteristics. Corporate management administers all properties as a whole rather than as discrete operating segments. Operational data is tracked by rig; however, financial performance is measured as a single enterprise and not on a rig-by-rig basis. Further, the allocation of capital resources is employed on a project-by-project basis across our entire asset base to maximize profitability without regard to individual geographic areas. Asset Impairment As a result of the rapidly deteriorating market conditions described in "COVID-19 Pandemic and Market Conditions Update", we concluded that a triggering event occurred as of March 31, 2020 and, accordingly, an interim asset impairment test was performed. As a result, we recognized impairment of $3.3 million associated with the decline in the market value of our assets held for sale based upon the market approach method and $13.3 million related to the remaining assets on rigs removed from our marketed fleet, as well as certain other component equipment and inventory; all of which was deemed to be unsaleable and of zero value based upon the current macroeconomic conditions and uncertainties surrounding COVID-19. We have not identified any additional triggering event and did not record any asset impairment during the three months ended June 30, 2020 or September 30, 2020. Due to the uncertainty around COVID-19 and current market conditions, we may have to make further impairment charges in future periods relating to, among other things, fixed assets and inventory. We performed an impairment test during the quarter ended September 30, 2019 and recorded an impairment charge of $2.3 million, which represented the impairment of 100% of our previously recorded goodwill. In June 2019, we reduced property, plant and equipment on our consolidated balance sheet by $3.1 million and recorded $3.1 million of asset impairment expense for certain drilling equipment on our silicon-controlled rectifier (“SCR”) rigs. Additionally, in the first and second quarters of 2019, we reduced property, plant and equipment on our consolidated balance sheet by $2.3 million and $1.7 million, respectively, and recorded $2.0 million and $1.1 million, respectively, of asset impairment expense in conjunction with the sale of miscellaneous drilling equipment and reduced assets held for sale on our consolidated balance sheet by $1.2 million and recorded $1.2 million of asset impairment expense related to miscellaneous drilling equipment previously held for sale, but deemed unsalable in the current market environment. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, as additional guidance on the measurement of credit losses on financial instruments. The new guidance requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. In addition, the guidance amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The new guidance is effective for public companies for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. In October 2019, the FASB approved a proposal which grants smaller reporting companies additional time to implement FASB standards on current expected credit losses (CECL) to January 2023. As a smaller reporting company, we will defer adoption of ASU 2016-13 until January 2023. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, to simplify the accounting for income taxes. The amendments in the update are effective for public companies for interim and annual periods beginning after December 15, 2020, with early adoption permitted. We plan to adopt this guidance on January 1, 2021 and are currently evaluating the impact of adoption on our consolidated financial statements. On April 1, 2020, we adopted the new standard, ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform (e.g., discontinuation of LIBOR) if certain criteria are met. As of September 30, 2020, we have not yet elected any optional expedients provided in the standard. We will apply the accounting relief as relevant contract and hedge accounting relationship modifications are made during the reference rate reform transition period. We do not expect the standard to have a material impact on our consolidated financial statements.
