Accounting Standards Updates
Accounting Standards Updates	Note 3—Accounting Standards Updates Recently adopted accounting standards Leases—Effective January 1, 2019, we adopted the accounting standards update that requires lessees to recognize a right-of-use asset and lease liability for virtually all leases and updates previous accounting standards for lessors to align certain requirements with the updates to the revenue recognition accounting standards. We applied the transition method that required us to recognize right-of-use assets, recorded in other assets, and lease liabilities, recorded in other current liabilities and other long-term liabilities, as of the date of our adoption with no adjustment to prior periods. We applied the package of practical expedients that permitted us to carry forward historical lease classifications. For our drilling contracts, we recognize revenues based on the predominant component, which is the service component. As of January 1, 2019, for the finance leases under which we are the lessee, we reclassified to other assets $528 million, representing the unamortized right-of-use asset previously recorded in property and equipment, and we reclassified an aggregate remaining lease liability of $511 million, including $32 million and $479 million recorded in other current liabilities and other long-term liabilities, respectively, previously recorded in debt due within one year and debt. As of January 1, 2019, for operating leases under which we are the lessee, we recorded a non-cash adjustment to recognize an aggregate right-of-use asset of $95 million, recorded in other assets, and a corresponding aggregate remaining lease liability of $133 million, including $15 million and $118 million recorded in other current liabilities and other long-term liabilities, respectively. We have accounted for lease and non-lease components of our operating leases as a single component. We have not recognized right-of-use assets or lease liabilities for our short-term leases. Our adoption did not have and is not expected in the future to have a material effect on our consolidated statements of financial position, operations or cash flows. See Note 9—Leases. Other comprehensive income—Effective January 1, 2019, we adopted the accounting standards update that allows for a reclassification from accumulated other comprehensive loss to accumulated deficit for stranded tax effects resulting from legislation commonly referred to as the Tax Cuts and Jobs Act (the “2017 Tax Act”). As of January 1, 2019, as a result of our adoption, we recorded an increase of $24 million to accumulated deficit with a corresponding decrease to accumulated other comprehensive loss. Recently issued accounting standards Financial instruments – credit losses—Effective January 1, 2020, we will adopt the accounting standards update that requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings. The update is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual periods. We have established our approach to apply the requirements and do not expect our adoption to have a material effect on our consolidated statements of financial position, operations or cash flows or on the disclosures contained in our notes to consolidated financial statements.
