Derivative Instruments (Gains And Losses On Derivatives Designated As Cash Flow Hedges) (Details) - USD ($)

Losses on interest rate lock derivatives reclassified from AOCI into income (effective portion) were included in interest expense, net, in our condensed consolidated statements of operations.

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

Gains and losses recognized in income for ineffectiveness and amounts excluded from effectiveness testing were included in other, net, in our condensed consolidated statements of operations. As a result of our adoption of Update 2017-12, which we adopted effective January 1, 2019, ineffectiveness is no longer separately measured and recognized. See additional information in Note 1.
