Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Hedge Contracts | MARKET RISKS AND DERIVATIVE AND HEDGE CONTRACTS We are exposed to financial and market risks that affect our businesses. We have concentrations of credit risk as a result of trade receivables owed to us by companies in the energy industry. We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. As a result of our variable rate bank credit facilities, including the variable rate credit facility of CCLP, we face market risk exposure related to changes in applicable interest rates. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures. Derivative Contracts Stock Warrants. In December 2016, we issued the Warrants in connection with an offering of our common stock. The warrants are exercisable into shares of our common stock at an exercise price of $5.75 per share. The fair value of the Warrants are calculated using the Black-Scholes valuation model, and totaled $13.2 million as of December 31, 2017, and is classified as Warrant Liability, a long-term liability, on the consolidated balance sheet. Warrant fair value (gains) and losses during 2017 and 2016 was $(5.3) million and $2.1 million, respectively, charged to Warrants fair value adjustment, in the accompanying consolidated statement of operations. Foreign Currency Derivative Contracts. We and CCLP enter into 30-day foreign currency forward derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries. As of December 31, 2017, we and CCLP had the following foreign currency derivative contracts outstanding relating to a portion of our foreign operations:
Derivative Contracts |  | U.S. Dollar Notional Amount |  | Traded Exchange Rate |  | Settlement Date
|  | (In Thousands) |  |  |  |
Forward purchase euro |  | $ | 1,743 |  |  | 1.19 |  |  | 1/18/2018
Forward purchase pounds sterling |  | $ | 5,998 |  |  | 1.33 |  |  | 1/18/2018
Forward sale Canadian dollar |  | $ | 3,756 |  |  | 1.29 |  | 1/18/2018
Forward purchase Mexican peso |  | $ | 6,974 |  |  | 19.28 |  |  | 1/18/2018
Forward sale Norwegian krone |  | $ | 4,131 |  |  | 8.40 |  |  | 1/18/2018
Forward sale Mexican peso |  | $ | 6,067 |  |  | 19.28 |  | 1/18/2018
As of December 31, 2016, we and CCLP had the following foreign currency derivative contracts outstanding relating to a portion of our foreign operations:
Derivative Contracts |  | US Dollar Notional Amount |  | Traded Exchange Rate |  | Settlement Date
|  | (In Thousands) |  |  |  |
Forward purchase euro |  | $ | 509 |  |  | 1.07 |  | 1/18/2017
Forward purchase pounds sterling |  | $ | 6,258 |  |  | 1.28 |  | 1/18/2017
Forward purchase Mexican peso |  | $ | 6,740 |  |  | 20.18 |  | 1/18/2017
Forward sale Norwegian krone |  | $ | 2,322 |  |  | 8.53 |  | 1/18/2017
Forward sale Mexican peso |  | $ | 2,483 |  |  | 20.18 |  | 1/18/2017
Under this program, we and CCLP may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as an economic hedge of the cash flow of our currency exchange risk exposure, they are not formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period. The fair value of foreign currency derivative instruments are based on quoted market values as reported to us by our counterparty (a level 2 fair value measurement). The fair values of our foreign currency derivative instruments as of December 31, 2017 and 2016, are as follows:
Foreign currency derivative instruments | Balance Sheet Location |  | Fair Value at December 31, 2017 | Fair Value at December 31, 2016
|  |  |  | (In Thousands)
Forward purchase contracts |  | Current assets |  | $ | 111 |  | $ | — |
Forward sale contracts |  | Current assets |  | 130 |  | 81 |
Forward purchase contracts |  | Current liabilities |  | (113 | ) | (371 | )
Total |  |  |  | $ | (127 | ) | $ | (290 | )
None of the foreign currency derivative contracts contain credit risk related contingent features that would require us to post assets or collateral for contracts that are classified as liabilities. During the year ended December 31, 2017, 2016, and 2015, we recognized approximately $(1.3) million, $2.0 million and $0.6 million of net (gains) losses reflected in other expense, net, associated with our foreign currency derivative program.
