Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE INSTRUMENTS

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. These transactions are remeasured in U.S. dollars based on a combination of both current and historical exchange rates. We previously used derivatives to reduce our exposure to various market risks, primarily foreign currency exchange rate risk.

The commencement of the Chapter 11 Cases constituted a termination event with respect to the Company’s derivative instruments, which permitted the counterparties of our derivative instruments to terminate their outstanding contracts. The exercise of these termination rights are not stayed under the Bankruptcy Code and the counterparties elected to terminate their outstanding derivatives with us in September 2020 for an aggregate settlement of $3.6 million which was recorded as a gain in Contract drilling expense in our Consolidated Statements of Operations for the year ended December 31, 2020 (Predecessor). As a result, we no longer had derivative assets or liabilities on our Consolidated Balance Sheet as of December 31, 2020 (Predecessor). During the four months ended April 30, 2021 (Predecessor) and eight months ended December 31, 2021 (Successor), we did not enter into derivative contracts; therefore, we do not have derivative assets or liabilities on our Consolidated Balance Sheet as of December 31, 2021(Successor).

Historically we have utilized cash flow hedges to hedge forecasted foreign currency denominated transactions, primarily to reduce our exposure to foreign currency exchange rate risk associated with contract drilling expenses and capital expenditures denominated in various currencies. Gains and losses, net of tax, on derivatives designated as cash flow hedges included in our Consolidated Statements of Operations and comprehensive loss were as follows (in millions):


	Gain (Loss) Recognized in Other Comprehensive Income ("OCI") on Derivatives (Effective Portion)

(1)Changes in the fair value of cash flow hedges are recorded in AOCI. Amounts recorded in AOCI associated with cash flow hedges are subsequently reclassified into contract drilling expense, depreciation or interest expense as earnings are affected by the underlying hedged forecasted transaction.

(2)Losses on interest rate lock derivatives reclassified from AOCI into income were included in Interest expense, net, in our Consolidated Statements of Operations.

(3)During the four months ended April 30, 2021 (Predecessor), $5.6 million of gains were reclassified from AOCI into Loss on impairment in our Consolidated Statements of Operations in connection with the impairment of certain rigs. During the year ended December 31, 2020 (Predecessor), $2.0 million of losses were reclassified from AOCI into Contract drilling expense and $13.6 million of gains were reclassified from AOCI into Depreciation expense in our Consolidated Statements of Operations. During the year ended December 31, 2019 (Predecessor), $7.3 million of losses were reclassified from AOCI into Contract drilling expense and $0.9 million of gains were reclassified from AOCI into Depreciation expense in our Consolidated Statements of Operations.

We have net assets and liabilities denominated in numerous foreign currencies and use various methods to manage our exposure to foreign currency exchange rate risk. We predominantly structure our drilling contracts in U.S. dollars, which significantly reduces the portion of our cash flows and assets denominated in foreign currencies. Historically, we have occasionally entered into derivatives that hedged the fair value of recognized foreign currency denominated assets or liabilities but did not designate such derivatives as hedging instruments. In these situations, a natural hedging relationship generally existed whereby changes in the fair value of the derivatives offset changes in the fair value of the underlying hedged items. As of December 31, 2021 (Successor) and December 31, 2020 (Predecessor) we did not have open derivative contracts to hedge against this risk.

Net losses of $0.2 million and $6.4 million associated with our derivatives not designated as hedging instruments were included in Other, net, in our Consolidated Statements of Operations for the years ended December 31, 2020 and 2019 (Predecessor), respectively.
