Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements We follow fair value measurement authoritative accounting guidance for measuring fair values of assets and liabilities in financial statements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We utilize market data or assumptions that market participants who are independent, knowledgeable, and willing and able to transact would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. We are able to classify fair value balances based on the observability of these inputs. The authoritative guidance for fair value measurements establishes three levels of the fair value hierarchy, defined as follows: •Level 1: Unadjusted, quoted prices for identical assets or liabilities in active markets. •Level 2: Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly for substantially the full term of the asset or liability. •Level 3: Significant, unobservable inputs for use when little or no market data exists, requiring a significant degree of judgment. The hierarchy gives the highest priority to Level 1 measurements and the lowest priority to Level 3 measurements. Depending on the particular asset or liability, input availability can vary depending on factors such as product type, longevity of a product in the market and other particular transaction conditions. In some cases, certain inputs used to measure fair value may be categorized into different levels of the fair value hierarchy. For disclosure purposes under the accounting guidance, the lowest level that contains significant inputs used in valuation should be chosen. Financial Assets and Liabilities A summary of financial assets and liabilities that are measured at fair value on a recurring basis, as of December 31, 2020 and 2019, were as follows (in thousands):

Our derivative financial instruments consist of short-duration foreign currency forward contracts. The fair value of derivative financial instruments is based on quoted market values including foreign exchange forward rates and interest rates. The fair value is computed by discounting the projected future cash flow amounts to present value. At December 31, 2019, derivative financial instruments are included in the financial statement line item accounts payable and accrued liabilities in our consolidated balance sheets. Our investments associated with our deferred compensation plan consist primarily of the cash surrender value of life insurance policies and is included in other assets on the consolidated balance sheets. The liability associated with our deferred compensation plan is included in other liabilities on the consolidated balance sheets. Our investments change as a result of contributions, payments, and fluctuations in the market. Assets and liabilities, measured using significant observable inputs, are reported at fair value based on third-party broker statements, which are derived from the fair value of the funds’ underlying investments. We also have marketable securities in publicly traded equity securities as an indirect result of strategic investments. They are reported at fair value based on the price of the stock and are included in other assets on the consolidated balance sheets. Assets and Liabilities Measured at Fair Value on a Non-recurring Basis We apply the provisions of the fair value measurement standard to our non-recurring, non-financial measurements including business combinations and assets identified as held for sale, as well as impairment related to goodwill and other long-lived assets. For business combinations, the purchase price is allocated to the assets acquired and liabilities assumed based on a discounted cash flow model for most intangibles as well as market assumptions for the valuation of equipment and other fixed assets. We perform our goodwill impairment assessment for each reporting unit by comparing the estimated fair value of each reporting unit to the reporting unit’s carrying value, including goodwill. We estimate the fair value for each reporting unit using a discounted cash flow analysis based on management’s short-term and long-term forecast of operating performance. This analysis includes significant assumptions regarding discount rates, revenue growth rates, terminal growth rates and the timing of expected future cash flows based on market conditions. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, an impairment loss is measured and recorded. When conducting an impairment test on long-lived assets, other than goodwill, we first compare estimated future undiscounted cash flows associated with the asset to the asset’s carrying amount. If the undiscounted cash flows are less than the asset’s carrying amount, we then determine the asset’s fair value by using a discounted cash flow analysis. These analyses are based on estimates such as management’s short-term and long-term forecast of operating performance, including revenue growth rates and expected profitability margins, estimates of the remaining useful life and service potential of the asset, and a discount rate based on our weighted average cost of capital. For assets that meet the criteria to be classified as held for sale, a market approach is used to determine fair value based on third-party appraisal reports. The impairment assessments discussed above incorporate inherent uncertainties, including projected commodity pricing, supply and demand for our services and future market conditions, which are difficult to predict in volatile economic environments and could result in impairment charges in future periods if actual results materially differ from the estimated assumptions utilized in our forecasts. If crude oil prices decline significantly and remain at low levels for a sustained period of time, we could be required to record an impairment of the carrying value of our long-lived assets in the future which could have a material adverse impact on our operating results. Given the unobservable nature of the inputs, the discounted cash flow models are deemed to use Level 3 inputs. Other Fair Value Considerations The carrying values on our consolidated balance sheets of our cash and cash equivalents, short-term investments, trade accounts receivable, other current assets, accounts payable and accrued liabilities and lines of credit approximate fair values due to their short maturities.
