Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments | Fair Value of Financial Instruments, Assets and Other Assets Financial Instruments and Other Assets Measured and Recognized at Fair Value We estimate fair value at a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market for the asset or liability. Our valuation techniques require inputs that we categorize using a three level hierarchy, from highest to lowest level of observable inputs. Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices or other market data for similar assets and liabilities in active markets, or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based upon our own judgment and assumptions used to measure assets and liabilities at fair value. Classification of a financial asset or liability within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. Other than the derivative instruments discussed in “Note 11 – Derivative Instruments” and held for sale assets and liabilities described in “Note 5 – Business Combinations and Divestitures,” we had no other material assets or liabilities measured and recognized at fair value on a recurring basis at March 31, 2019 and December 31, 2018. Fair Value of Other Financial Instruments Our other financial instruments include cash and cash equivalents, accounts receivable, accounts payable, held-to-maturity investments, short-term borrowings and long-term debt. The carrying value of our cash and cash equivalents, accounts receivable, accounts payable, and short-term borrowings approximates their fair value due to their short maturities. These short-term borrowings are classified as Level 2 in the fair value hierarchy. The fair value of our short-term and long-term borrowings are discussed in “Note 9 – Short-term Borrowings and Other Debt Obligations.” As of March 31, 2019 and December 31, 2018, we have $50 million of held-to-maturity Angolan government bonds maturing in 2020. The carrying value of $50 million in both periods approximate their fair value as of March 31, 2019 and December 31, 2018. We assess whether an other-than-temporary impairment loss on the investment has occurred due to a decline in fair value or other market conditions. If the fair value of the security is below amortized cost and it is more likely than not that we will not be able to recover its amortized cost basis before its stated maturity, we will record an other-than-temporary impairment charge in the Consolidated Statements of Operations. Non-recurring Fair Value Measurements - Impairments In the first quarter of 2019, our interim goodwill impairment tests indicated that our goodwill was impaired and as a result one of our reporting units was written down to its estimated fair value. The Level 3 fair values of our reporting units were determined using a combination of the income and market approach. The unobservable inputs to the income approach included each reporting unit’s estimated future cash flows and estimates of discount rates commensurate with the reporting unit’s risks. The market approach considered market multiples of comparable publicly traded companies to estimate fair value as a multiple of each reporting unit’s actual and forecasted earnings. |
