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 (exit price). 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, 2015 and 2014 were as follows (in thousands):
| Quoted Prices in Active Markets |  | Significant Other Observable Inputs |  | Significant Unobservable Inputs |  |

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. The derivative financial instruments are included in accounts receivable, net in our consolidated balance sheets. Our investments associated with our deferred compensation plan consist of marketable securities that are held in the form of investments in mutual funds within insurance contracts. 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. Other marketable securities and investments are included in other assets on the consolidated balance sheets. Our valuation technique used to estimate the fair value of contingent consideration payable in connection with our acquisition of Timco (as described in Note 4) is the Monte Carlo simulation lattice option-pricing model which uses weekly rig count forecasts through June 30, 2017 as a basis for the simulation. The contingent consideration is included in other non-current liabilities on the balance sheet. We used the following assumptions in the Monte Carlo simulation lattice option-pricing model:
| December 31, 2015
Assumptions: |
Rig count volatility | 1.85 | %
Cost of debt | 5.31 | %
Date of first contingent consideration payment | December 31, 2016 |
Date of second contingent consideration payment | June 30, 2017 |
The following table sets forth a reconciliation of the changes in the fair value of the contingent consideration payable, which changed as a result of the significant reduction in the rig count forecast. The contingent consideration is classified as Level 3 in the fair value hierarchy (in thousands):
| Significant

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 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 utilize a discounted cash flow model in evaluating impairment considerations related to goodwill and long-lived assets. Given the unobservable nature of the inputs, the discounted cash flow models are deemed to use Level 3 inputs. There were no non-recurring measurements during the periods presented. Other Fair Value Considerations The carrying values on our consolidated balance sheet of our cash and cash equivalents, trade accounts receivable, other current assets, accounts payable, accrued and other current liabilities and lines of credit approximate fair values due to their short maturities.
