TETRA Technologies, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
(Unaudited)
NOTE A – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, water management, frac flowback, production well testing and offshore rig cooling services, and compression services and equipment. We were incorporated in Delaware in 1981. Following the acquisition and disposition transactions that closed during the three month period ended March 31, 2018, we reorganized our reporting segments and are now composed of three divisions – Completion Fluids & Products, Water & Flowback Services, and Compression. Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis.
Our consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The information furnished reflects all normal recurring adjustments, which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. Operating results for the period ended June 30, 2018 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2018.
We consolidate the financial statements of CSI Compressco LP and its subsidiaries ("CCLP") as part of our Compression Division, as we determined that CCLP is a variable interest entity and we are the primary beneficiary. We control the financial interests of CCLP and have the ability to direct the activities of CCLP that most significantly impact its economic performance through our ownership of its general partner. The share of CCLP net assets and earnings that is not owned by us is presented as noncontrolling interest in our consolidated financial statements. Our cash flows from our investment in CCLP are limited to the quarterly distributions we receive on our CCLP common units and general partner interest (including incentive distribution rights) and the amounts collected for services we perform on behalf of CCLP, as TETRA's capital structure and CCLP's capital structure are separate, and do not include cross default provisions, cross collateralization provisions, or cross guarantees.
The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission ("SEC") and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. These financial statements should be read in connection with the financial statements for the year ended December 31, 2017, and notes thereto included in our Annual Report on Form 10-K, which we filed with the SEC on March 5, 2018.
Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material.
Reclassifications
Certain previously reported financial information has been reclassified to conform to the current period’s presentation. For a discussion of the reclassification of the financial presentation of our Offshore Division as discontinued operations, see Note C - "Discontinued Operations."
Cash Equivalents
We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents.
6

Restricted Cash
Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve month period. Restricted cash as of June 30, 2018 consists of cash used to secure outstanding letters of credit of our Compression Division.
Inventories
Inventories are stated at the lower of cost or net realizable value. Except for work in progress inventory discussed below, cost is determined using the weighted average method. Components of inventories as of June 30, 2018 and December 31, 2017 are as follows:

| June 30, 2018 |  | December 31, 2017
| (In Thousands)
Finished goods | $ | 60,011 |  |  | $ | 66,377 |
Raw materials | 3,934 |  |  | 4,027 |
Parts and supplies | 44,585 |  |  | 33,632 |
Work in progress | 24,837 |  |  | 11,402 |
Total inventories | $ | 133,367 |  |  | $ | 115,438 |

Finished goods inventories include newly manufactured clear brine fluids as well as used brines that are repurchased from certain customers for recycling. Recycled brines are recorded at cost, using the weighted average method. Work in progress inventory consists primarily of new compressor packages located in the CCLP fabrication facility in Midland, Texas. The cost of work in progress is determined using the specific identification method. We write down the value of inventory by an amount equal to the difference between its cost and its estimated net realizable value.
Net Income (Loss) per Share
The following is a reconciliation of the weighted average number of common shares outstanding with the number of shares used in the computations of net income (loss) per common and common equivalent share:

| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2018 |  | 2017 |  | 2018 |  | 2017
| (In Thousands)
Number of weighted average common shares outstanding | 122,474 |  |  | 114,534 |  |  | 125,553 |  |  | 114,375 |
Assumed exercise of equity awards and warrants | — |  |  | — |  |  | — |  |  | — |
Average diluted shares outstanding | 122,474 |  |  | 114,534 |  |  | 125,553 |  |  | 114,375 |

For the three and six month periods ended June 30, 2018 and June 30, 2017, the average diluted shares outstanding excludes the impact of all outstanding equity awards and warrants, as the inclusion of these shares would have been anti-dilutive due to the net losses recorded during the periods. In addition, for the three and six month periods ended June 30, 2018 and June 30, 2017, the calculation of diluted earnings per common share excludes the impact of the CCLP Preferred Units, as the inclusion of the impact from conversion of the CCLP Preferred Units into CCLP common units would have been anti-dilutive.
Foreign Currency Translation
We have designated the euro, the British pound, the Norwegian krone, the Canadian dollar, the Brazilian real, the Argentine peso, and the Mexican peso, as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Norway, Canada, Brazil, Argentina, and certain of our operations in Mexico, respectively. The U.S. dollar is the designated functional currency for all of our other foreign operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled $0.6 million and $(0.3) million during the
7

three and six month periods ended June 30, 2018 and $0.6 million and $1.2 million during the three and six month periods ended June 30, 2017, respectively.
On June 30, 2018, we determined the economy in Argentina to be highly inflationary. As a result of this determination, beginning July 1, 2018, our reporting of our operations in Argentina will reflect the remeasurement of the functional currency from the Argentine peso to the U.S. dollar.
Income Taxes
Our consolidated provision for income taxes during the first six months of 2017 and 2018 is primarily attributable to taxes in certain foreign jurisdictions and Texas gross margin taxes. Our consolidated effective tax rate for the six month period ended June 30, 2018 of negative 12.1% was primarily the result of losses generated in entities for which no related tax benefit has been recorded. The losses generated by these entities do not result in tax benefits due to offsetting valuation allowances being recorded against the related net deferred tax assets. We establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.
The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. At June 30, 2018 and December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we made reasonable estimates of the effects and recorded provisional amounts. We will continue to make and refine our calculations as additional analysis is completed. The accounting for the tax effects of the Act will be completed in 2018 as provided by the U.S. Securities and Exchange Commission’s SAB No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act. We recognized an income tax expense of $54.1 million in the fourth quarter of 2017 associated with the impact of the Act, which was fully offset by a decrease in the valuation allowance previously recorded on our net deferred tax assets. As such, the Act resulted in no net tax expense in the fourth quarter of 2017. We have considered in our estimated annual effective tax rate for 2018, the impact of the statutory changes enacted by the Act, including reasonable estimates of those provisions effective for the 2018 tax year. Our estimate on Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), and IRC Section 163(j) interest limitation do not impact our effective tax rate for the three and six month periods ended June 30, 2018.
Asset Retirement Obligations
We operate facilities in various U.S. and foreign locations that are used in the manufacture, storage, and sale of our products, inventories, and equipment. These facilities are a combination of owned and leased assets. We are required to take certain actions in connection with the retirement of these assets. The values of our asset retirement obligations for these properties were $12.1 million and $11.7 million as of June 30, 2018 and December 31, 2017, respectively. Asset retirement obligations are recorded in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 410, "Asset Retirement and Environmental Obligations," whereby the estimated fair value of a liability for asset retirement obligations is recognized in the period in which it is incurred and in which a reasonable estimate can be made. Such estimates are based on relevant assumptions that we believe are reasonable. We have reviewed our obligations in this regard in detail and estimated the cost of these actions. The associated asset retirement costs are capitalized as part of the carrying amount of these long-lived assets and are depreciated on a straight-line basis over the life of the assets.
The changes in the values of our asset retirement obligations during the three and six month period ended June 30, 2018, are as follows:

Beginning balance for the period, as reported | $ | 11,929 |  |  | $ | 11,738 |
Activity in the period: |  |  |

Revisions in estimated cash flows | (6 | ) |  | 26 |
Ending balance | $ | 12,073 |  |  | $ | 12,073 |

We review the adequacy of our asset retirement obligation liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed.
Fair Value Measurements
Fair value is defined as “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” within an entity’s principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.
Under U.S. generally accepted accounting principles ("GAAP"), the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which could include the reporting entity’s own judgments about the assumptions market participants would utilize in pricing the asset or liability.
We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized on a recurring basis in the determination of the carrying values of the liabilities for the warrants to purchase 11.2 million shares of our common stock (the "Warrants") and the CCLP Preferred Units (as herein defined). We also utilize fair value measurements on a recurring basis in the accounting for our foreign currency derivative contracts. For these fair value measurements, we utilize the quoted value as determined by our counterparty financial institution (a level 2 fair value measurement). Fair value measurements are also utilized on a nonrecurring basis in certain circumstances, such as in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill (a level 3 fair value measurement), the initial recording of our asset retirement obligations, and for the impairment of long-lived assets, including goodwill (a level 3 fair value measurement). The fair values of certain of our financial instruments, which include cash, restricted cash, accounts receivable, accounts payable, short-term borrowings, and long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The aggregate fair values of our long-term 11% Senior Note at June 30, 2018 and December 31, 2017, were approximately $128.2 million and $130.8 million, respectively, based on current interest rates on those dates, which were different from the stated interest rate on the 11% Senior Note. Those fair values compare to the face amount of the 11% Senior Note of $125.0 million both at June 30, 2018 and December 31, 2017. The fair values of the publicly traded CCLP 7.25% Senior Notes (as herein defined) at June 30, 2018 and December 31, 2017, were approximately $271.5 million and $279.7 million, respectively. Those fair values compare to the face amount of $295.9 million both at June 30, 2018 and December 31, 2017. The fair value of the publicly traded CCLP 7.50% Senior Secured Notes at June 30, 2018 was approximately $351.8 million. This fair value compares to aggregate principal amount of such notes at June 30, 2018 of $350.0 million. We calculated the fair values of our 11% Senior Note as of June 30, 2018 and December 31, 2017 internally, using current market conditions and average cost of debt (a level 2 fair value measurement). We based the fair values of the CCLP 7.25% Senior Notes and the CCLP 7.50% Senior Secured Notes as of June 30, 2018 on recent trades for these notes (a level 1 fair value measurement). See Note D - "Long-Term Debt and Other Borrowings," for further discussion.

The CCLP Preferred Units are valued using a lattice modeling technique that, among a number of lattice structures, includes significant unobservable items (a Level 3 fair value measurement). These unobservable items include (i) the volatility of the trading price of CCLP's common units compared to a volatility analysis of equity prices of CCLP's comparable peer companies, (ii) a yield analysis that utilizes market information related to the debt yields of comparable peer companies, and (iii) a future conversion price analysis. The fair valuation of the CCLP Preferred Units liability is increased by, among other factors, projected increases in CCLP's common unit price and by increases in the volatility and decreases in the debt yields of CCLP's comparable peer companies. Increases (or decreases) in the fair value of CCLP Preferred Units will increase (decrease) the associated liability and result in future adjustments to earnings for the associated valuation losses (gains). During the three and six month periods ended June 30, 2018, the changes in the fair value of the CCLP Preferred Units resulted in $0.5 million being credited to earnings and $0.8 million charged to earnings, respectively, in the consolidated statement of operations.
The Warrants are valued either by using their traded market prices (a level 1 fair value measurement) or, for periods when market prices are not available, by using the Black Scholes option valuation model that includes estimates of the volatility of the Warrants implied by their trading prices (a level 3 fair value measurement). As of June 30, 2018 and December 31, 2017, the fair valuation methodology utilized for the Warrants was a level 3 fair value measurement, as there were no available traded market prices to value the Warrants. The fair valuation of the Warrants liability is increased by, among other factors, increases in our common stock price, and by increases in the volatility of our common stock price. Increases (or decreases) in the fair value of the Warrants will increase (decrease) the associated liability and result in future adjustments to earnings for the associated valuation losses (gains). During the three and six month periods ended June 30, 2018, the changes in the fair value of the Warrants liability resulted in $2.2 million being charged to earnings and $0.2 million being charged to earnings, respectively, in the consolidated statement of operations.
During the third quarter of 2017 and the first quarter of 2018, we issued stand-alone, cash-settled stock appreciation rights awards to an executive officer. These awards are valued by using the Black Scholes option valuation model and such fair value is recognized based on the portion of the requisite service period satisfied as of each valuation date. The fair valuation of the stock appreciation rights liability is increased by, among other factors, increases in our common stock price, and by increases in the volatility of our common stock price. These stock appreciation rights awards are reflected as an accrued liability in our consolidated balance sheet. Increases (or decreases) in the fair value of the stock appreciation rights awards will increase (decrease) the associated liability and result in future adjustments to earnings for the associated valuation losses (gains). During the six months ended June 30, 2018, the fair value of the stock appreciation rights increased $0.2 million, which was charged to earnings in the consolidated statement of operations.
A summary of these fair value measurements as of June 30, 2018 and December 31, 2017, is as follows:

New Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers." This ASU supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") 605, "Revenue Recognition," and most industry-specific guidance. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those years, under either full or modified retrospective adoption.
On January 1, 2018, we adopted ASU 2014-09 and all related amendments ("ASU 2014-09"). We utilized the modified retrospective method of adoption. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.
The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also provides a five-step model for determining revenue recognition for arrangements that are within the scope of the standard: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of ASU 2014-09, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. For a complete discussion of accounting for revenues, see Note J - Revenue from Contracts with Customers.
The impact from the adoption of ASU 2014-09 to our January 1, 2018 consolidated balance sheet, our June 30, 2018 consolidated balance sheet, and our consolidated results of operations for the three and six month periods ended June 30, 2018 was immaterial. The adoption of ASU 2014-09 had no impact to cash provided by operating, financing, or investing activities in our consolidated statement of cash flows. We do not expect the adoption of the new revenue standard to have a material impact to our net income on an ongoing basis.
In February 2016, the FASB issued ASU 2016-02, "Leases" (Topic 842) to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities on the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, the ASU will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We are currently assessing the potential effects of these changes to our consolidated financial statements. Our current operating lease portfolio consists primarily of real estate, vehicles, and equipment leases. Based on our preliminary assessment, upon adoption of the ASU, we will record significant right-to-use assets and lease obligations pursuant to the new requirements. We
11

are evaluating our portfolio of existing leases for consideration of the accounting impact of each lease. We are also evaluating and are developing internal policies to address the requirements under this ASU.
In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses. ASU 2016-13, which has an effective date of the first quarter of fiscal 2022, also applies to employee benefit plan accounting. We are currently assessing the potential effects of these changes to our consolidated financial statements and employee benefit plan accounting.
In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" to reduce diversity in practice in classification of certain transactions in the statement of cash flows. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a retrospective transition adoption. We adopted this ASU during the three month period ended March 31, 2018, with no material impact to our consolidated financial statements.
In November 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. We adopted this ASU during the three month period ended March 31, 2018. The adoption of this standard did not have a material impact to our consolidated financial statements due to a previously recorded valuation allowance on our net deferred tax assets.
Additionally, in November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" to reduce diversity in the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. We adopted this ASU during the three month period ended March 31, 2018, resulting in restricted cash being classified with cash and cash equivalents in our consolidated statement of cash flows.
In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for annual periods beginning after December 15, 2020, and interim periods within those annual periods, with early adoption permitted, under a prospective adoption. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. We adopted this ASU during the three month period ended March 31, 2018, with no material impact to our consolidated financial statements.
In July 2017, the FASB issued ASU 2017-11, "Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception" to consider “down round” features when determining whether certain equity-linked financial instruments or embedded features are indexed to an entity’s own stock. Entities that present EPS under ASC 260 will recognize the effect of a down round feature in a freestanding equity-classified financial instrument only when it is triggered. The effect of triggering such a feature will be recognized as a dividend and a reduction to income available to common shareholders in basic EPS. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements.
In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" to change how companies account for and disclose hedges. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements.
In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods
12

within those annual periods, with early adoption permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.
NOTE B – ACQUISITIONS AND DISPOSITIONS
Acquisition of SwiftWater Energy Services
On February 28, 2018, pursuant to a purchase agreement dated February 13, 2018 (the "SwiftWater Purchase Agreement"), we purchased all of the equity interests in SwiftWater Energy Services, LLC ("SwiftWater"), which is engaged in the business of providing water management and water solutions to oil and gas operators in the Permian Basin market of Texas. Strategically, the acquisition of SwiftWater enhances our position as one of the leading integrated water management companies, providing water transfer, storage, and treatment services, along with proprietary automation technology and numerous other water-related services.
Under the terms of the SwiftWater Purchase Agreement, consideration of $42.0 million of cash, subject to a working capital adjustment, and 7,772,021 shares of our common stock (valued at $28.2 million) were paid at closing. Subsequent to closing, in August 2018, a working capital adjustment of approximately $1.0 million was paid. The sellers will also have the right to receive contingent consideration payments, in an aggregate amount of up to $15.0 million, calculated on EBITDA and revenue (each as defined in the SwiftWater Purchase Agreement) of the water management business of SwiftWater and all of our pre-existing operations in the Permian Basin in respect of the period from January 1, 2018 through December 31, 2019. The contingent consideration may be paid in cash or shares of our common stock, at our election.
As of June 30, 2018, our preliminary allocation of the SwiftWater purchase price is as follows (in thousands):

Current assets | $ | 16,880 |
Property and equipment | 11,631 |
Intangible assets | 41,960 |
Goodwill | 15,560 |
Total assets acquired | 86,031 |
Current liabilities | 7,189 |
Total liabilities assumed | 7,189 |
Net assets acquired | $ | 78,842 |

The above allocation of the purchase price to the SwiftWater net tangible assets and liabilities considers approximately $7.6 million of the initial estimated fair value for the liabilities associated with the contingent purchase price consideration. The fair value of the obligation to pay the contingent purchase price consideration was calculated based on the anticipated EBITDA and revenue as of the closing date for the operations of SwiftWater and our pre-existing operations in the Permian Basin and could increase (to $15.0 million) or decrease (to $0) depending on the actual earnings from these operations going forward. Increases or decreases in the value of the anticipated contingent purchase price consideration liability due to changes in the amounts paid or expected to be paid will be charged or credited to earnings in the period in which such changes occur. During the period from the closing date to June 30, 2018, the estimated fair value for the liabilities associated with the contingent purchase price consideration increased to $11.9 million, resulting in $4.3 million being charged to other expense during the three month period ended June 30, 2018.
The allocation of the purchase price to the SwiftWater net tangible assets and liabilities and identifiable intangible assets, as well as the contingent consideration liabilities, as of February 28, 2018, is preliminary and subject to revisions to the fair value calculations for certain of the tangible and identified intangible assets as well as the fair value calculation of the contingent purchase price consideration liability. The final purchase price allocation could differ materially from the preliminary allocation noted in the summary above. The preliminary allocation of purchase price includes approximately $15.6 million of deductible goodwill allocated to our Water & Flowback Services segment, and is supported by the strategic benefits discussed above and expected to be generated from
13

the acquisition. The acquired property and equipment is stated at fair value, and depreciation on the acquired property and equipment is computed using the straight-line method over the estimated useful lives of each asset. Machinery and equipment is depreciated using useful lives of 3 to 15 years; and automobiles and trucks are depreciated using useful lives of 3 to 4 years. The acquired intangible assets include $3.3 million for the trademark/tradename, $37.2 million for customer relationships, and $1.5 million of other intangible assets that are stated at estimated fair value and are amortized on a straight-line basis over their estimated useful lives, ranging from 5 to 16 years. These identified intangible assets are recorded net of $1.0 million of accumulated amortization as of June 30, 2018.
For the six month period ended June 30, 2018, our revenues, depreciation and amortization, and pretax earnings included $36.6 million, $2.1 million, and $7.0 million, respectively, associated with the SwiftWater acquisition after the closing on February 28, 2018. In addition, SwiftWater acquisition-related costs of approximately $0.4 million were incurred during the six month period ended June 30, 2018, consisting of external legal fees, transaction consulting fees, and due diligence costs. These costs have been recognized in general and administrative expenses in the consolidated statement of operations.
The pro forma information presented below has been prepared to give effect to the SwiftWater acquisition as if the transaction had occurred at the beginning of the periods presented. The pro forma information includes the impact from the allocation of the acquisition purchase price on depreciation and amortization. The pro forma information also excludes the SwiftWater acquisition-related costs charged to earnings during the 2018 period. The pro forma information is presented for illustrative purposes only and is based on estimates and assumptions we deemed appropriate. The following pro forma information is not necessarily indicative of the historical results that would have been achieved if the acquisition transaction had occurred in the past, and our operating results may have been different from those reflected in the pro forma information below. Therefore, the pro forma information should not be relied upon as an indication of the operating results that we would have achieved if the transaction had occurred at the beginning of the periods presented or the future results that we will achieve after the transaction.

Sale of Offshore Division
On March 1, 2018, we closed a series of related transactions that resulted in the disposition of our Offshore Division. Pursuant to an Asset Purchase and Sale Agreement (the "Maritech Asset Purchase Agreement") with Orinoco Natural Resources, LLC ("Orinoco"), Orinoco purchased certain remaining offshore oil, gas and mineral leases and related assets of Maritech (the "Maritech Properties"). Immediately thereafter, we closed the transactions contemplated by a Membership Interest Purchase and Sale Agreement (the "Maritech Equity Purchase Agreement") with Orinoco, whereby Orinoco purchased all of the equity interests of Maritech (the "Maritech Equity Interests"). Immediately thereafter, we closed the transactions contemplated by an Equity Interest Purchase Agreement (the "Offshore Services Purchase Agreement") with Epic Offshore Specialty, LLC, an affiliate of Orinoco ("Epic Offshore"), whereby Epic Offshore (the "Offshore Services Sale") purchased all of the equity interests in the wholly owned subsidiaries that comprised our Offshore Services segment operations (the "Offshore Services Equity Interests").
Under the terms of the Maritech Asset Purchase Agreement, the Maritech Equity Purchase Agreement, and the Offshore Services Purchase Agreement, the consideration delivered by Orinoco and Epic Offshore for the Maritech Properties, the Maritech Equity Interests and the Offshore Services Equity Interests consisted of (i) the assumption by Orinoco of substantially all of the liabilities and obligations relating to the ownership, operation and
14

condition of the Maritech Properties and the provision of certain indemnities by Orinoco to us under the Maritech Asset Purchase Agreement, (ii) the assumption by Orinoco of substantially all of the liabilities of Maritech and the provision of certain indemnities by Orinoco under the Maritech Equity Purchase Agreement, (iii) the assumption by Epic Offshore of substantially all of the liabilities of the Offshore Services Equity Interests relating to the periods following the closing of the Offshore Services Sale and the provision of certain indemnities by Epic Offshore under the Offshore Services Purchase Agreement, (iv) cash in the amount $3.1 million, (v) a promissory note in the original principal amount of $7.5 million payable by Epic Offshore to us in full, together with interest at a rate of 1.52% per annum, on December 31, 2019, (vi) performance by Orinoco under a Bonding Agreement executed in connection with the Maritech Asset Purchase Agreement and the Maritech Equity Purchase Agreement whereby Orinoco provided at closing non-revocable performance bonds in an amount equal to $46.8 million to cover the performance by Orinoco and Maritech of the asset retirement obligations of Maritech, and (vii) the delivery of a personal guaranty agreement from Thomas M. Clarke and Ana M. Clarke guaranteeing the payment obligations of Orinoco under the Bonding Agreement (collectively, the "Transaction Consideration"). Pursuant to the Bonding Agreement, Orinoco is required to replace, within 90 days following the closing, the initial bonds delivered at closing with non-revocable performance bonds, meeting certain requirements, in the aggregate sum of $47.0 million. Orinoco has not delivered such replacement bonds and we are seeking to enforce the terms of the Bonding Agreement. The non-revocable performance bonds delivered at the closing remain in effect.
As a result of these transactions, we have effectively exited the businesses of our Offshore Services and Maritech segments, and these operations are reflected as discontinued operations in our consolidated financial statements. See Note C - "Discontinued Operations" for further discussion. Our consolidated pre-tax results of operations for the six month period ending June 30, 2018 included a loss on the disposal of our Offshore Division of $33.8 million, net of tax, including transaction costs of $1.4 million.
NOTE C – DISCONTINUED OPERATIONS
As discussed in Note B - "Acquisitions and Dispositions," on March 1, 2018, we closed a series of related transactions that resulted in the disposition of our Offshore Division. As a result, we have accounted for our Offshore Division, consisting of our Offshore Services and Maritech segments, as discontinued operations and have revised prior period financial statements to exclude these businesses from continuing operations. A summary of financial information related to our discontinued operations is as follows:

NOTE D – LONG-TERM DEBT AND OTHER BORROWINGS
We believe TETRA's capital structure and CCLP's capital structure should be considered separately, as there are no cross default provisions, cross collateralization provisions, or cross guarantees between CCLP's debt and TETRA's debt.
Consolidated long-term debt as of June 30, 2018 and December 31, 2017, consists of the following:

As of June 30, 2018, TETRA (excluding CCLP) had a $61.0 million outstanding balance and $6.8 million in letters of credit against its Credit Agreement, leaving a net availability of $132.2 million. There was no balance outstanding under the CCLP New Credit Agreement (as defined below) as of June 30, 2018.
As described below, we and CCLP are in compliance with all covenants of our respective debt and senior note agreements as of June 30, 2018.
Our Long-Term Debt
Our Credit Agreement.
17

At June 30, 2018, our consolidated leverage ratio was 2.18 to 1 (compared to a 4.75 to 1 maximum allowed under the Credit Agreement) and our fixed charge coverage ratio was 2.87 to 1 (compared to a 1.25 to 1 minimum required under the Credit Agreement).
CCLP Long-Term Debt
CCLP Senior Secured Notes. On March 8, 2018, CCLP, and its wholly owned subsidiary, CSI Compressco Finance Inc. (together with CCLP, the "CCLP Issuers") entered into the Purchase Agreement (the “Purchase Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated as representative of the initial purchasers listed in Schedule A thereto (collectively, the “Initial Purchasers”), pursuant to which the CCLP Issuers agreed to issue and sell to the Initial Purchasers $350 million aggregate principal amount of the CCLP Issuers’ 7.50% Senior Secured First Lien Notes due 2025 (the "CCLP Senior Secured Notes") (the "CCLP Offering") pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act").
The CCLP Issuers closed the Offering on March 22, 2018. The CCLP Senior Secured Notes were issued at par for net proceeds of approximately $343.8 million, after deducting certain financing costs. CCLP used a portion of the net proceeds to repay in full and terminate its existing bank Credit Agreement and plans to use the remainder for general partnership purposes, including the expansion of its compression fleet. The CCLP Senior Secured Notes are jointly and severally, and fully and unconditionally, guaranteed (the "Guarantees" and, together with the CCLP Senior Secured Notes, the "CCLP Senior Secured Note Securities") on a senior secured basis initially by each of CCLP's domestic restricted subsidiaries (other than CSI Compressco Finance Inc., certain immaterial subsidiaries and certain other excluded domestic subsidiaries) and are secured by a first-priority security interest in substantially all of the CCLP Issuers' and the Guarantors' assets (other than certain excluded assets) (the "Collateral") as collateral security for their obligations under the CCLP Senior Secured Notes, subject to certain permitted encumbrances and exceptions. On the closing date, CCLP entered into an indenture (the "Indenture") by and among the Obligors and U.S. Bank National Association, as trustee with respect to the Securities. The CCLP Senior Secured Notes accrue interest at a rate of 7.50% per annum. Interest on the CCLP Senior Secured Notes is payable semi-annually in arrears on April 1 and October 1 of each year, beginning October 1, 2018. The CCLP Senior Secured Notes are scheduled to mature on April 1, 2025. During the six months ended June 30, 2018, CCLP incurred total financing costs of $6.7 million related to the CCLP Senior Secured Notes. These costs are deferred, netting against the carrying value of the amount outstanding.
On and after April 1, 2021, CCLP may redeem all or a part of the CCLP Senior Secured Notes, from time to time, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest thereon to, but not including, the applicable redemption date, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the 12-month period beginning on April 1 of the years indicated below:

Date |  | Price
2021 |  | 105.625 | %
2022 |  | 103.750 | %
2023 |  | 101.875 | %
2024 |  | 100.000 | %

In addition, at any time and from time to time before April 1, 2021, CCLP may, at its option, redeem all or a portion of the CCLP Senior Secured Notes at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium (as defined in the Indenture) with respect to the CCLP Senior Secured Notes plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date, subject to the rights of holders of the CCLP Senior Secured Notes on the relevant record date to receive interest due on the relevant interest payment date.
Prior to April 1, 2021, CCLP may on one or more occasions redeem up to 35% of the principal amount of the CCLP Senior Secured Notes with an amount of cash not greater than the amount of the net cash proceeds from one or more equity offerings at a redemption price equal to 107.500% of the principal amount of the CCLP Senior Secured Notes to be redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the right of holders of record on the relevant record date to receive interest due on the
18

relevant interest payment date, provided that (a) at least 65% of the aggregate principal amount of the CCLP Senior Secured Notes originally issued on the issue date (excluding notes held by CCLP and its subsidiaries) remains outstanding after each such redemption; and (b) the redemption occurs within 180 days after the date of the closing of the equity offering.
If CCLP experiences certain kinds of changes of control, each holder of the CCLP Senior Secured Notes will be entitled to require CCLP to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that holder’s CCLP Senior Secured Notes pursuant to an offer on the terms set forth in the Indenture. CCLP will offer to make a cash payment equal to 101% of the aggregate principal amount of the CCLP Senior Secured Notes repurchased plus accrued and unpaid interest, if any, on the CCLP Senior Secured Notes repurchased to the date of repurchase, subject to the rights of holders of the CCLP Senior Secured Notes on the relevant record date to receive interest due on the relevant interest payment date.
The Indenture contains customary covenants restricting CCLP's ability and the ability of CCLP restricted subsidiaries to: (i) pay distributions on, purchase or redeem CCLP common units or purchase or redeem any CCLP subordinated debt; (ii) incur or guarantee additional indebtedness or issue certain kinds of preferred equity securities; (iii) create or incur certain liens securing indebtedness; (iv) sell assets, including dispositions of the Collateral; (v) consolidate, merge or transfer all or substantially all of its assets; (vi) enter into transactions with affiliates; and (vii) enter into agreements that restrict distributions or other payments from its restricted subsidiaries to CCLP. These covenants are subject to a number of important limitations and exceptions, including certain provisions permitting CCLP, subject to the satisfaction of certain conditions, to transfer assets to certain of CCLP's unrestricted subsidiaries. Moreover, if the CCLP Senior Secured Notes receive an investment grade rating from at least two rating agencies and no default has occurred and is continuing under the Indenture, many of the restrictive covenants in the Indenture will be terminated. The Indenture also contains customary events of default and acceleration provisions relating to such events of default, which provide that upon an event of default under the Indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding CCLP Senior Secured Notes may declare all of the CCLP Senior Secured Notes to be due and payable immediately.
On March 22, 2018, CCLP, the grantors named therein, the Trustee and U.S. Bank National Association, as the collateral trustee (the “Collateral Trustee”), entered into a collateral trust agreement (the “Collateral Trust Agreement”) pursuant to which the Collateral Trustee will receive, hold, administer, maintain, enforce and distribute the proceeds of all of its liens upon the collateral for the benefit of the current and future holders of the CCLP Senior Secured Notes and any future priority lien obligations, if any.
CCLP Bank Credit Facilities.
On March 22, 2018, in connection with the closing of the CCLP Offering, CCLP repaid all outstanding borrowings and obligations under its existing CCLP Credit Agreement with a portion of the net proceeds from the CCLP Offering, and terminated the CCLP Credit Agreement. As a result of the termination of the CCLP Credit Agreement, associated unamortized deferred financing costs of $3.5 million were charged to other (income) expense, net, during the three month period ended March 31, 2018.
On June 29, 2018, CCLP and two of its wholly owned subsidiaries (collectively the "CCLP Borrowers"), and certain of its wholly owned subsidiaries named therein as guarantors (the "CCLP New Credit Agreement Guarantors"), entered into a Loan and Security Agreement (the "CCLP New Credit Agreement") with the lenders thereto (the "Lenders"), and Bank of America, N.A., in its capacity as administrative agent, collateral agent, letter of credit issuer, and swing line lender. All of the CCLP Borrowers' obligations under the CCLP New Credit Agreement are guaranteed by certain of their existing and future domestic subsidiaries. The CCLP New Credit Agreement includes a maximum credit commitment of $50.0 million available for loans, letters of credit (with a sublimit of $25.0 million) and swingline loans (with a sublimit of $5.0 million). Such maximum credit commitment may be increased by $25.0 million in accordance with the terms and conditions of the CCLP New Credit Agreement.
The CCLP Borrowers may borrow funds under the CCLP New Credit Agreement to pay fees and expenses related to the CCLP New Credit Agreement and for the Borrower's ongoing working capital needs and for general business purposes. The revolving loans under the CCLP New Credit Agreement may be voluntarily prepaid, in whole or in part, without premium or penalty, subject to breakage or similar costs. The maturity date of the CCLP New Credit Agreement is June 29, 2023. As of June 30, 2018, no balance was outstanding under the CCLP New Credit Agreement. Because there was no outstanding balance on the CCLP New Credit Agreement, associated
19

deferred financing costs of $1.3 million as of June 30, 2018, were classified as other assets on the accompanying consolidated balance sheet.
Borrowings under the CCLP New Credit Agreement will bear interest at a rate per annum equal to, at the option of the CCLP Borrowers, either (i) London InterBank Offered Rate (“LIBOR”) (adjusted to reflect any required bank reserves) for an interest period equal to 30, 60, 90, 180 or 360 days (as selected by the CCLP Borrowers, subject to availability and with the consent of the Lenders for 360 days) plus a margin based on average daily excess availability or (ii) a base rate plus a margin based on average daily excess availability; such base rate shall be determined by reference to the highest of (a) the prime rate of interest announced from time to time by Bank of America, N.A., (b) the Federal Funds Rate (as defined in the CCLP New Credit Agreement) rate plus 0.5% per annum and (c) LIBOR (adjusted to reflect any required bank reserves) for a 30-day interest period on such day plus 1.0% per annum. Initially, from June 29, 2018 until the delivery of the financial statements for the fiscal quarter ending December 31, 2018, LIBOR-based loans will have an applicable margin of 2.00% per annum and base-rate loans will have an applicable margin of 1.00% per annum; thereafter, the applicable margin will range between 1.75% and 2.25% per annum for LIBOR-based loans and 0.75% and 1.25% per annum for base-rate loans, according to average daily excess availability when financial statements are delivered. In addition to paying interest on outstanding principal under the CCLP New Credit Agreement, the CCLP Borrowers will be required to pay a commitment fee in respect of the unutilized commitments thereunder, initially at the rate of 0.375% per annum until the delivery of the financial statements for the fiscal quarter ending September 30, 2018 and thereafter at the applicable rate ranging from 0.250% to 0.375% per annum, paid quarterly in arrears based on utilization of the commitments under the CCLP New Credit Agreement. The CCLP Borrowers will also be required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans and fronting fees.
The CCLP New Credit Agreement contains certain affirmative and negative covenants, including covenants that restrict the ability of the CCLP Borrowers, the CCLP New Credit Agreement Guarantors and certain of their subsidiaries to take certain actions including, among other things and subject to certain significant exceptions, the incurrence of debt, the granting of liens, the making of investments, entering into transactions with affiliates, the payment of dividends and the sale of assets. The CCLP New Credit Agreement also contains a requirement that the CCLP Borrowers comply, during certain periods, with a fixed charge coverage ratio of 1.0 to 1.0.
All obligations under the CCLP New Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first priority security interest for the benefit of the Lenders in the CCLP Borrowers’ and the CCLP New Credit Agreement Guarantors’ present and future accounts receivable, inventory and related assets and proceeds of the foregoing (the “CCLP ABL Collateral”).
NOTE E – CCLP SERIES A CONVERTIBLE PREFERRED UNITS
During 2016, CCLP entered into Series A Preferred Unit Purchase Agreements (the “CCLP Unit Purchase Agreements”) with certain purchasers to issue and sell in two private placements (the "Initial Private Placement" and "Subsequent Private Placement," respectively) an aggregate of 6,999,126 of CSI Compressco LP Series A Convertible Preferred Units representing limited partner interests in CCLP (the “CCLP Preferred Units”) for a cash purchase price of $11.43 per CCLP Preferred Unit (the “Issue Price”), resulting in total 2016 net proceeds to CCLP, after deducting certain offering expenses, of $77.3 million. We purchased 874,891 of the CCLP Preferred Units in the Initial Private Placement at the aggregate Issue Price of $10.0 million.
We and the other holders of CCLP Preferred Units (each, a “CCLP Preferred Unitholder”) receive quarterly distributions, which are paid in kind in additional CCLP Preferred Units, equal to an annual rate of 11.00% of the Issue Price ($1.2573 per unit annualized), subject to certain adjustments. The rights of the CCLP Preferred Units include certain anti-dilution adjustments, including adjustments for economic dilution resulting from the issuance of CCLP common units in the future below a set price.
A ratable portion of the CCLP Preferred Units has been, and will continue to be, converted into CCLP common units on the eighth day of each month over a period of thirty months that began in March 2017 (each, a “Conversion Date”), subject to certain provisions of the Second Amended and Restated CCLP Partnership Agreement that may delay or accelerate all or a portion of such monthly conversions. On each Conversion Date, a portion of the CCLP Preferred Units will convert into CCLP common units representing limited partner interests in CCLP in an amount equal to, with respect to each CCLP Preferred Unitholder, the number of CCLP Preferred Units held by such CCLP Preferred Unitholder divided by the number of Conversion Dates remaining, subject to
20

adjustment described in the Second Amended and Restated CCLP Partnership Agreement, with the conversion price (the "Conversion Price") determined by the trading prices of the common units over the prior month, among other factors, and as otherwise impacted by the existence of certain conditions related to the CCLP common units. Based on the number of CCLP Preferred Units outstanding as of June 30, 2018, the maximum aggregate number of CCLP common units that could be required to be issued pursuant to the conversion provisions of the CCLP Preferred Units is approximately 25.5 million CCLP common units; however, CCLP may, at its option, pay cash, or a combination of cash and common units, to the CCLP Preferred Unitholders instead of issuing common units on any Conversion Date, subject to certain restrictions as described in the Second Amended and Restated CCLP Partnership Agreement. The total number of CCLP Preferred Units outstanding as of June 30, 2018 was 4,458,803, of which we held 559,975.
Because the CCLP Preferred Units may be settled using a variable number of CCLP common units, the fair value of the CCLP Preferred Units, net of the units we purchased, is classified as long-term liabilities on our consolidated balance sheet in accordance with ASC 480 "Distinguishing Liabilities and Equity." The fair value of the CCLP Preferred Units as of June 30, 2018 was $45.6 million. During the three and six month period ended June 30, 2018, changes in the fair value during each period, resulted in $0.5 million being credited to earnings and $0.8 million being charged to earnings, respectively, in the accompanying consolidated statements of operations. During the three and six month period ended June 30, 2017, changes in the fair value resulted in $4.8 million being credited to earnings and $3.2 million being credited to earnings, respectively, in the accompanying consolidated statements of operations.
Based on the conversion provisions of the CCLP Preferred Units, and using the Conversion Price calculated as of June 30, 2018, the theoretical number of CCLP common units that would be issued if all of the outstanding CCLP Preferred Units were converted on June 30, 2018 on the same basis as the monthly conversions would be approximately 9.9 million CCLP common units, with an aggregate market value of $55.2 million. A $1 decrease in the Conversion Price would result in the issuance of 2.4 million additional CCLP common units pursuant to these conversion provisions.
NOTE F – MARKET RISKS AND DERIVATIVE 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 foreign currencies as well as to investments in certain of our international operations. As a result of our variable rate bank credit facility, 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
Foreign Currency Derivative Contracts. We and CCLP each enter into 30-day foreign currency forward derivative contracts with third parties as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries. As of June 30, 2018, we and CCLP had the following foreign currency derivative contracts outstanding relating to portions of our foreign operations:

Derivative Contracts |  | US Dollar Notional Amount |  | Traded Exchange Rate |  | Settlement Date
|  | (In Thousands) |  |  |  |
Forward purchase Euro |  | $ | 464 |  |  | 1.16 |  | 7/19/2018

|  | (In Thousands) |  |  |  |
Forward purchase Euro |  | 27,437 |  |  | 10.16 |  | 7/19/2018

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 values 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 and CCLP's foreign currency derivative instruments as of June 30, 2018 and December 31, 2017, are as follows:

Foreign currency derivative instruments | Balance Sheet Location |  | Fair Value at June 30, 2018 |  | Fair Value at December 31, 2017
|  |  |  | (In Thousands)
Forward purchase contracts |  | Current assets |  | $ | 158 |  |  | $ | 111 |
Forward sale contracts |  | Current assets |  | 22 |  |  | 130 |
Forward sale contracts |  | Current liabilities |  | (241 | ) |  | (255 | )
Forward purchase contracts |  | Current liabilities |  | — |  |  | (113 | )
Net asset (liability) |  |  |  | $ | (61 | ) |  | $ | (127 | )

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 three and six month periods ended June 30, 2018, we recognized $0.7 million and $0.8 million of net gains (losses), respectively, reflected in other (income) expense, net, associated with our foreign currency derivative program. During the three and six month periods ended June 30, 2017, we recognized $0.4 million and $1.1 million of net gains (losses), respectively, reflected in other (income) expense, net, associated with our foreign currency derivative program.

NOTE H – COMMITMENTS AND CONTINGENCIES
Litigation
We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.
On March 18, 2011, we filed a lawsuit in the Circuit Court of Union County, Arkansas, asserting claims of professional negligence, breach of contract and other claims against the engineering firm we hired for engineering design, equipment, procurement, advisory, testing and startup services for our El Dorado, Arkansas chemical production facility. The engineering firm disputed our claims and promptly filed a motion to compel the matter to
23

arbitration. After a lengthy procedural dispute in Arkansas state court, arbitration proceedings were initiated on November 15, 2013. Ultimately, on December 16, 2016, the arbitration panel ruled in our favor, declared us as the prevailing party, and awarded us a total net amount of $12.8 million. We received full payment of the $12.8 million final award on January 5, 2017, and this amount was credited to earnings in the accompanying consolidated statement of operations for the six months ended June 30, 2017.
Other Contingencies
During 2011, in connection with the sale of a significant majority of Maritech's oil and gas producing properties, the buyers of the properties assumed the associated decommissioning liabilities pursuant to the purchase and sale agreements. In March 2018, we closed the Maritech Asset Purchase Agreement with Orinoco that provided for the purchase by Orinoco of the Maritech Properties. Also in March 2018, we finalized the Maritech Equity Purchase Agreement with Orinoco that provided for the purchase by Orinoco of the Maritech Equity Interests. As a result of these transactions, we have effectively exited the businesses of our Offshore Services and Maritech segments and Orinoco has assumed all of Maritech's remaining abandonment and decommissioning obligations. For further discussion of the sale of the Maritech Properties, see Note B - "Acquisitions and Dispositions."
NOTE I – INDUSTRY SEGMENTS
Following the transactions closed during the three month period ended March 31, 2018, we reorganized our reporting segments and now manage our operations through three Divisions: Completion Fluids & Products, Water & Flowback Services, and Compression. Our Completion Fluids & Products Division was previously reported as our Fluids Division, and included our water management services operations. Following the acquisition of SwiftWater in February 2018, our expanded water management operations are now included with our production testing operations as part of our Water & Flowback Services Division. The operations of our previous Offshore Division, consisting of our previous Offshore Services and Maritech segments, are now reported as discontinued operations following their disposal in March 2018.
Our Completion Fluids & Products Division manufactures and markets clear brine fluids, additives, and associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations in the United States and in certain countries in Latin America, Europe, Asia, the Middle East, and Africa. The division also markets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry.
Our Water & Flowback Services Division provides domestic onshore oil and gas operators with comprehensive water management services. The division also provides frac flowback, production well testing, offshore rig cooling, and other associated services in many of the major oil and gas producing regions in the United States, Mexico, and Canada, as well as in basins in certain regions in South America, Africa, Europe, the Middle East, and Australia.
The Compression Division is a provider of compression services and equipment for natural gas and oil production, gathering, transportation, processing, and storage. The Compression Division's equipment sales business includes the fabrication and sale of standard compressor packages, custom-designed compressor packages, and oilfield pump systems designed and fabricated at the division's facilities. The Compression Division's aftermarket services business provides compressor package reconfiguration and maintenance services as well as providing compressor package parts and components manufactured by third-party suppliers. The Compression Division provides its services and equipment to a broad base of natural gas and oil exploration and production, midstream, transmission, and storage companies operating throughout many of the onshore producing regions of the United States as well as in a number of foreign countries, including Mexico, Canada, and Argentina.
We generally evaluate the performance of and allocate resources to our segments based on profit or loss from their operations before income taxes and nonrecurring charges, return on investment, and other criteria. Transfers between segments and geographic areas are priced at the estimated fair value of the products or services as negotiated between the operating units. “Corporate overhead” includes corporate general and administrative expenses, corporate depreciation and amortization, interest income and expense, and other income and expense.

NOTE J – REVENUE FROM CONTRACTS WITH CUSTOMERS
Performance Obligations. Revenue is recognized when performance obligations under the terms of a contract with our customer are satisfied. Generally this occurs with the transfer of control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. For a general discussion of the nature of the goods and services that we provide, see Note I - "Industry Segments."
Product Sales. Product sales revenues are recognized at a point in time when we transfer control of our product offerings to our customers, generally when we ship products from our facility to our customer. The product sales for our Completion Fluid & Products Division consist primarily of clear brine fluids, additives, and associated manufactured products. Product sales for our Water & Flowback Services Division are typically attributed to specific performance obligations within certain production testing service arrangements. Parts and equipment sales comprise the product sales for the Compression Division.
Services. Service revenues represent revenue recognized over time, as our customer arrangements typically provide agreed upon day-rates (monthly service rates for compression services) and we recognize service revenue based upon the number of days services have been performed. Service revenue recognized over time is associated with a majority of our Water & Flowback Services Division arrangements, compression service and aftermarket service contracts within our Compression Division, and a small portion of Completion Fluids & Products Division revenue that is associated with completion fluid service arrangements. With the exception of the initial terms of the compression services contracts for medium- and high-horsepower compressor packages of our Compression Division, our customer contracts are generally for terms of one year or less. The majority of the service arrangements in the Water & Flowback Services Division are for a period of 90 days or less. Within our Compression Division service revenue, most aftermarket service revenues are recognized at a point in time when we transfer control of our products and complete the delivery of services to our customers.
We receive cash equal to the invoice price for most product sales and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. Since the period between when we deliver products or services and when the customer pays for products or services are not expected to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts.
Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation. For example, consideration received from customers during the fabrication of new compressor packages is typically deferred until control of the compressor package is transferred to our customer. For any arrangements with multiple performance obligations, we use management's estimated selling price to determine the stand-alone selling price for separate performance obligations. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period. As of June 30, 2018, we had $6.4 million of remaining performance obligations related to our compression service contracts. As a practical expedient, this amount does not reflect revenue for compression service contracts whose original expected duration is less than 12 months an d does not consider the effects of the time value of money. The remaining performance obligations are expected to be recognized through 2022 as follows (in thousands):

| 2018 |  | 2019 |  | 2020 |  | 2021 |  | 2022 |  | Total
| (In Thousands)
Compression service contracts remaining performance obligations | $ | 1,791 |  |  | $ | 3,209 |  |  | $ | 1,027 |  |  | $ | 253 |  |  | $ | 77 |  |  | $ | 6,357 |

Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We have elected to recognize the cost for freight and shipping costs as part of cost of product sales when control over our products (i.e. delivery) has transferred to the customer.
Use of Estimates. C ontracts where the amount of revenue that will ultimately be realized is subject to uncertainties not fully known as of the time revenue is recognized are known as variable consideration arrangements. In recognizing revenue for these arrangements, the amount of variable consideration recognized is limited so that it is probable that significant amounts of revenues will not be reversed in future periods when the
27

uncertainty is resolved. For products returned by the customer, we estimate the expected returns based on an analysis of historical experience. For volume discounts earned by the customer, we estimate the discount (if any) based on our estimate of the total expected volume of products sold or services to be provided to the customer during the discount period. In certain contracts for the sale of clear brine fluids, we may agree to issue credits for the repurchase of reclaimable used fluids from certain customers at an agreed price that is based on the condition of the fluids. For sales of clear brine fluids, we adjust the revenue recognized in the period of shipment by the estimated amount of the credit expected to be issued to the customer, and this estimate is based on historical experience. As of June 30, 2018, the amount of remaining credits expected to be issued for the repurchase of reclaimable used fluids was $1.1 million tha t were recorded in inventory (right of return asset) and accounts payable. T here were no material differences between amounts recognized during the three month period ended June 30, 2018, compared to estimates made in a prior period from these variable consideration arrangements.
Contract Assets and Liabilities. Contract assets arise when we transfer products or perform services in fulfillment of a contract obligation but must perform other performance obligations before being entitled to payment. Generally, once we have transferred products or performed services for the customer pursuant to a contract, we recognize revenue and trade accounts receivable, as we are entitled to payment that is unconditional. Any contract assets, along with billed and unbilled accounts receivable, are included in Trade Accounts Receivable in our consolidated balance sheets. Contract liabilities arise when we receive consideration, or consideration is unconditionally due, from a customer prior to transferring products or services to the customer under the terms of a sales contract. We classify contract liabilities as Unearned Income in our consolidated balance sheets. Such deferred revenue typically results from advance payments received on sales of compressor equipment prior to when it is completed and transferred to the customer in accordance with the customer contract.
As of June 30, 2018 and December 31, 2017, contract assets were immaterial. The following table reflects the changes in our contract liabilities during the six month period ended June 30, 2018:

| June 30, 2018
| (In Thousands)
Unearned Income, beginning of period | $ | 17,050 |
Additional unearned income | 59,360 |
Revenue recognized | (47,276 | )
Unearned income, end of period | $ | 29,134 |

Bad debt expense on accounts receivables and contract assets was $0.1 million and $0.3 million du ring the three and six month periods ended June 30, 2018, respectively, and $0.3 million and $0.9 million during the three and six month periods ended June 30, 2017, respectively. During the three month period ended June 30, 2018, contract liabilities increased due to unearned income for consideration received on new compressor equipment being fabricated. During the six month period ended June 30, 2018, $47.3 million of unearned income was recognized as product sales revenue, primarily associated w ith deliveries of compression equipment.
Contract Costs. When costs are incurred to obtain contracts, such as professional fees and sales bonuses, such costs are deferred and amortized over the expected period of benefit. Costs of mobilizing service equipment necessary to perform under service contracts, if significant, are deferred and amortized over the estimated service period, which is generally a few weeks. As of June 30, 2018, such contract costs were immaterial. Where applicable, we establish provisions for estimated obligations pursuant to product warranties by accruing for estimated future product warranty cost in the period of the product sale. Such estimates are based on historical warranty loss experience. Major components of fabricated compressor packages have manufacturer warranties that we pass through to the customer.
Disaggregation of Revenue. We disaggregate revenue from contracts with customers into Product Sales and Services within each segment, as noted in our three reportable segments in Note I. In addition, we disaggregate revenue from contracts with customers by geography based on the following table below.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and accompanying notes included in this Quarterly Report. In addition, the following discussion and analysis also should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on March 5, 2018. This discussion includes forward-looking statements that involve certain risks and uncertainties.
Business Overview
Our consolidated results of operations during the three month period ended June 30, 2018, reflect the increased demand for many of our products and services compared to the corresponding prior year period. Consolidated revenues increased by 44.5% compared to the corresponding prior year quarter, improving for each of our divisions. This increase was led by a significant increase in Water & Flowback Services revenues, which included the impact of our February 2018 acquisition of SwiftWater Energy Services, LLC ("SwiftWater") along with strong growth in our existing operations. Increased domestic onshore rig count and activity levels in key markets has driven the improved operating results. The contribution from SwiftWater on Water & Flowback Services Division revenues and earnings is expected to continue going forward as we capture additional operating and administrative efficiencies with the acquired operations. Our Compression Division also reported increased revenues, as increased demand for compression services has resulted in increased utilization and customer contract pricing. New compressor equipment sales have also increased, and new orders for equipment have maintained the existing new equipment sales backlog. Our Completion Fluids & Products Division also reported a modest increase in revenues, as offshore activity levels remain challenged, although earnings decreased compared to the prior year quarter due to the completion of a TETRA CS Neptune(R) completion fluid project during 2017. In July 2018, we announced that we have entered into a global joint marketing and development agreement with Halliburton Energy Services, Inc. ("Halliburton") for the sale and distribution of TETRA CS Neptune completion fluids. Through this collaborative agreement with Halliburton, we expect to expand sales and jointly develop new oil and gas completion fluid product offerings based on our respective technologies and resource capabilities. Despite increased consolidated operating and administrative expenses and the working capital challenges accompanying our growing
29

operations, we anticipate continuing improved revenues and increasing operating cash flows during the remainder of 2018.
Following the strategic transactions that closed during the first quarter of 2018, we have continued to grow our core businesses to capitalize on the improving demand for our products and services. While continuing to consider suitable acquisition opportunities, we have grown organically through an increased capital expenditure program for our core businesses in selected markets. Our Compression Division increased its growth capital expenditure levels during the first six months of 2018 compared to the corresponding prior year period, as it continues to increase its compression equipment fleet to meet the increasing customer demand for compression services. In addition, we have also increased capital expenditure levels for our Water & Flowback Services Division, as we selectively grow our capacity in certain markets. As a result, growth capital expenditures have increased significantly during the first half of 2018 compared to the prior year period. To fund its growth, our CSI Compressco LP ("CCLP") subsidiary enhanced its long-term debt structure. Following the March 2018 repayment of its previous bank credit facility and the issuance of the 7.50% Senior Secured First Lien Notes due 2025 (the "CCLP Senior Secured Notes"), in June 2018, CCLP entered into that certain Loan and Security Agreement (the "CCLP New Credit Agreement"), which provides up to $50.0 million to fund ongoing working capital and letter of credit needs and for general business purposes. CCLP also had $51.4 million of available cash as of June 30, 2018, which is available to fund additional Compression Division growth capital expenditures. We also are pursuing opportunities to enhance our long-term debt structure in order to position us to support further strategic growth in the current market environment.
Approximately $632.5 million of our consolidated debt balance carrying value is owed by CCLP, serviced by CCLP's existing cash balances and cash provided by CCLP's operations (less its capital expenditures), and $343.5 million of which is secured by certain assets of CCLP. The following table provides condensed consolidating balance sheet information reflecting our net assets and CCLP's net assets that service and secure our and CCLP's respective capital structures.

Consolidated cash used by operating activities for the six months ended June 30, 2018 was $12.1 million compared to $0.6 million for the six months ended June 30, 2017, an increase of $11.6 million, despite improved operating profitability, primarily due to cash utilized due to timing of payments of accounts payable. Consolidated capital expenditures, net of sales proceeds, were $67.1 million during the six months ended June 30, 2018, and included $47.3 million of capital expenditures by our Compression Division, primarily for growth capital expenditures. Corresponding prior year period consolidated capital expenditures, net of sales proceeds, were $16.3 million, including $11.5 million by our Compression Division. Although our capital expenditure levels are expected to continue to be increased going forward, we defer or reduce capital expenditure projects where possible in order to conserve cash. Key objectives associated with our capital structure (excluding the capital structure of CCLP) include the ongoing management of amounts outstanding and available under our bank revolving credit facility and repayment of our 11% Senior Note. CCLP also continues to carefully monitor its 2018 capital expenditure program
30

in order to conserve its cash. During the first six months of 2018, we received $5.9 million from CCLP as our share of CCLP common unit and general partner distributions.
Critical Accounting Policies
In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. We base these estimates on historical experience, available information, and various other assumptions that we believe are reasonable. We periodically evaluate these estimates and judgments, including those related to potential impairments of long-lived assets (including goodwill), the collectability of accounts receivable, the current cost of future asset retirement obligations, and the allocation of acquisition purchase price. The fair values of portions of our total assets and liabilities are measured using significant unobservable inputs. The combination of these factors forms the basis for judgments made about the carrying values of assets and liabilities that are not readily apparent from other sources. These judgments and estimates may change as new events occur, as new information is acquired, and as changes in our operating environments are encountered. Actual results are likely to differ from our current estimates, and those differences may be material.
Acquisition Purchase Price Allocations
We account for acquisitions of businesses using the purchase method, which requires the allocation of the purchase price based on the fair values of the assets and liabilities acquired. We estimate the fair values of the assets and liabilities acquired using accepted valuation methods, and, in many cases, such estimates are based on our judgments as to the future operating cash flows expected to be generated from the acquired assets throughout their estimated useful lives. Following the February 28, 2018 acquisition of SwiftWater, we have accounted for the various assets (including intangible assets) and liabilities acquired based on our estimate of their fair values. Goodwill represents the excess of acquisition purchase price over the estimated fair values of the net assets acquired. Our estimates and judgments of the fair value of acquired businesses are imprecise, and the use of inaccurate fair value estimates could result in the improper allocation of the acquisition purchase price to acquired assets and liabilities, which could result in asset impairments, the recording of previously unrecorded liabilities, and other financial statement adjustments. The difficulty in estimating the fair values of acquired assets and liabilities is increased during periods of economic uncertainty.

Consolidated revenues during the current year quarter increased compared to the prior year quarter primarily due to a $52.6 million increase in Water & Flowback Services Division revenues. The increase in Water & Flowback Services Division revenues was primarily driven by increased activity in certain domestic and international markets and the February 28, 2018 acquisition of SwiftWater. Our Compression Division reported increased revenues of $24.6 million, primarily due to increased compressor equipment sales activity. See Divisional Comparisons section below for additional discussion.
Consolidated gross profit increased compared to the prior year quarter primarily due to the increased revenues of our Water & Flowback Services Division and Compression Division. Despite the improvement in the activity levels of certain of our businesses, the impact of pricing pressures continues to impact profitability in certain markets. Operating expenses reflect the increase in consolidated revenues, although we remain aggressive in managing operating costs and minimizing increased headcount, despite the increased operations.
Consolidated general and administrative expenses increased during the second quarter of 2018 compared to the prior year quarter, primarily due to increased salary and employee expenses of $1.7 million, increased insurance and other general expenses of $1.4 million, as well as increased professional services fees of $0.9 million. Increased general and administrative expenses were driven primarily by our Compression and Water & Flowback Services Division s. Due to the increased consolidated revenues discussed above, general and administrative expense as a percentage of revenues decreased compared to the prior year quarter.
Consolidated interest expense, net, increased during the second quarter of 2018 compared to the prior year quarter, primarily due to Compression Division interest expense. Compression Division interest expense increased due to the higher interest rate on the CCLP Senior Secured Notes, a portion of the proceeds of which were used to repay the balance outstanding under the CCLP Credit Agreement, and is expected to remain increased compared
32

to prior year periods. Interest expense during the 2018 and 2017 periods includes $0.9 million and $1.2 million, respectively, of finance cost amortization.
The Warrants are accounted for as a derivative liability in accordance with Accounting Standards Codification ("ASC") 815 and therefore they are classified as a long-term liability on our consolidated balance sheet at their fair value. Increases (or decreases) in the fair value of the Warrants are generally associated with increases (or decreases) in the trading price of our common stock, resulting in adjustments to earnings for the associated valuation losses (gains), and resulting in future volatility of our earnings during the period the Warrants are outstanding.
The CCLP Preferred Units may be settled using a variable number of CCLP common units, and therefore the fair value of the CCLP Preferred Units is classified as a long-term liability on our consolidated balance sheet in accordance with ASC 480. Because the CCLP Preferred Units are convertible into CCLP common units at the option of the holder, the fair value of the CCLP Preferred Units will generally increase or decrease with the trading price of the CCLP common units, and this increase (decrease) in CCLP Preferred Unit fair value will be charged (credited) to earnings, as appropriate, resulting in future volatility of our earnings during the period the CCLP Preferred Units are outstanding.
Consolidated other (income) expense, net, was $3.8 million of other expense during the current year quarter compared to $0.8 million of other expense during the prior year quarter, primarily due to $4.3 million of increased expense associated with the remeasurement of the contingent purchase price consideration for SwiftWater. This increase was offset by decreased other bank fees of $0.3 million and increased miscellaneous income of $0.4 million.
Our consolidated provision for income taxes during the second quarter of 2018 is primarily attributable to taxes in certain foreign jurisdictions and Texas gross margin taxes. Our consolidated effective tax rate for the three month period ended June 30, 2018 of negative 25.3% was primarily the result of losses generated in entities for which no related tax benefit has been recorded. The losses generated by these entities do not result in tax benefits due to offsetting valuation allowances being recorded against the related net deferred tax assets. We establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.
The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. At June 30, 2018 and December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we made reasonable estimates of the effects and recorded provisional amounts. We will continue to make and refine our calculations as additional analysis is completed. The accounting for the tax effects of the Act will be completed in 2018 as provided by the U.S. Securities and Exchange Commission’s SAB No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act. We recognized an income tax expense of $54.1 million in the fourth quarter of 2017 associated with the impact of the Act, which was fully offset by a decrease in the valuation allowance previously recorded on our net deferred tax assets. As such, the Act resulted in no net tax expense in the fourth quarter of 2017. We have considered in our estimated annual effective tax rate for 2018 the impact of the statutory changes enacted by the Act, including reasonable estimates of those provisions effective for the 2018 tax year. Our estimate on Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), and IRC Section 163(j) interest limitation do not impact our effective tax rate for the three months ended June 30, 2018.

The increase in Completion Fluids & Products Division revenues during the current year quarter compared to the prior year quarter was primarily due to $5.0 million of increased product sales revenue, attributed to increased manufactured product sales revenue. This increase more than offset a decrease in clear brine fluids ("CBF") and associated product sales revenues in the U.S. Gulf of Mexico as a result of a TETRA CS Neptune completion fluid project that was completed during 2017. Service revenues decreased $2.4 million primarily due to a reduction in completion services activity associated with the 2017 TETRA CS Neptune completion fluid project.
Completion Fluids & Products Division gross profit during the current year quarter decreased compared to the prior year quarter primarily due to the decreased revenues and profitability associated with the mix of CBF products and services, including the prior year impact of the TETRA CS Neptune completion fluid project discussed above. Completion Fluids & Products Division profitability in future periods will continue to be affected by the mix of its products and services, including the timing of TETRA CS Neptune completion fluid projects.
The Completion Fluids & Products Division reported a decrease in pretax earnings during the current year quarter compared to the prior year quarter primarily due to decreased gross profit discussed above. Completion Fluids & Products Division administrative cost levels decreased compared to the prior year quarter, as $0.7 million of decreased salary and employee related expenses and $0.3 million of decreased bad debt expense were offset by $0.1 million of increased legal and professional fees and $0.1 million of increased general expenses. The Completion Fluids & Products Division continues to review opportunities to further reduce its administrative costs. Other expense decreased primarily due to $0.2 million of increased miscellaneous income and increased foreign currency gains.

Water & Flowback Services Division revenues increased during the current year quarter compared to the prior year quarter, primarily due to increased water management services. Water management and flowback services activity increased $52.7 million resulting from the impact of increased demand, reflecting the growth in domestic onshore rig count. Approximately $28.6 million of the water management increase was generated from the operations of SwiftWater, which was acquired on February 28, 2018.
The Water & Flowback Services Division reflected increased gross profit during the current year quarter compared to the prior year quarter, due to the increase in revenues and improving customer pricing levels. However, customer pricing continues to be challenging due to excess availability of equipment in certain markets. The Water & Flowback Services Division continues to monitor its cost structure, minimizing increased costs despite increasing activity levels, and looking to capture additional synergies following the SwiftWater acquisition.
The Water & Flowback Services Division reported pretax income during the current year quarter compared to a pretax loss during the prior year quarter, primarily due to the improvement in gross profit described above. General and administrative expenses levels increased compared to the prior year quarter, primarily due to the acquisition of SwiftWater, increased salary and employee related expenses of $2.0 million, increased professional fees of $0.3 million, and increased insurance and other general expenses of $0.1 million. Other (income) expense increased primarily due to $4.3 million of increased expense associated with the remeasurement of the contingent purchase price consideration for SwiftWater offset by increased foreign currency gains of $0.3 million.

Compression Division revenues increased during the current year quarter compared to the prior year quarter, primarily due to a $16.7 million increase in product sales revenues, due to a higher number of new compressor equipment sales compared to the prior year quarter. Demand for new compressor equipment continues to improve, and the current new equipment sales backlog has increased significantly compared to the prior year quarter. In addition, current year revenues reflect a $7.9 million increase in service revenues from compression and aftermarket services operations. This increase in service revenues was primarily due to increasing demand for compression services, as reflected by increased compressor fleet utilization rates. Overall utilization of the Compression Division's compressor fleet has improved sequentially for seven consecutive quarterly periods, led by increased utilization of the high- and medium-horsepower fleet.
Compression Division gross profit increased during the current year quarter compared to the prior year quarter due to increased revenues discussed above. Higher compressor fleet utilization rates have led to increases in customer contract pricing.
The Compression Division recorded an increased pretax loss during the current year quarter compared to the prior year quarter despite increased gross profit discussed above. Interest expense increased compared to the prior year period, due to the higher interest rate on the CCLP Senior Secured Notes, which were issued in March 2018, compared to the interest rate on the previous CCLP Credit Agreement. Increased interest expense is expected to continue compared to the prior year periods. General and administrative expense levels increased
35

compared to the prior year quarter, due to increased salary and employee-related expenses, including equity compensation, of $1.6 million, increased other general expenses of $0.8 million and decreased bad debt expense of $0.1 million. Series A fair value adjustment resulted in $4.3 million decreased credit to earnings in the current year quarter compared to the prior year period. Other (income) expense, net, reflected income primarily due to increased foreign currency gains.

Corporate Overhead pretax loss increased during the current year quarter compared to the prior year quarter, primarily due to the Warrants fair value adjustment. The fair value of the outstanding Warrants liability resulted in a $2.2 million charge to earnings during 2018 compared to a $5.5 million credit to earnings in the prior year quarter. In addition, interest expense increased due to increased borrowings. Corporate general and administrative expense decreased due to $1.2 million of decreased salary, incentives and employee related expenses, which was partially offset by $0.5 million of increased professional service fees, $0.4 million of increased other general expenses, and $0.1 million of increased consulting marketing fees.

Consolidated revenues for 2018 increased compared to the prior year period, primarily due to increased Water & Flowback Services Division revenues, which increased by $75.5 million. The increase in Water & Flowback Services Division revenues was primarily driven by increased activity in certain domestic and international markets and the February 28, 2018 acquisition of SwiftWater. Our Compression Division reported increased revenues of $44.5 million, primarily due to increased compressor equipment sales activity. See Divisional Comparisons section below for additional discussion.
Consolidated gross profit increased during the current year period compared to the prior year period primarily due to the increased revenues of our Water & Flowback Services Division and Compression Division. Despite the improvement in activity levels of certain of our businesses, the impact of pricing pressures continues to challenge profitability in certain markets. Operating expenses reflect the increase in consolidated revenues, although we remain aggressive in managing operating costs and minimizing increased headcount, despite the increased operations.
Consolidated general and administrative expenses increased during the current year period compared to the prior year period, primarily due to $3.1 million of increased professional services fees, $2.7 million of increased salary related expenses and $2.3 million of insurance and other general expenses. Increased general and administrative expenses were driven primarily by our Compression and Water & Flowback Services Division s. Due to the increased consolidated revenues discussed above, general and administrative expense as a percentage of revenues decreased compared to the prior year period.

Consolidated interest expense, net, increased in the current year period primarily due to Compression Division interest expense. Compression Division interest expense increased due to the higher interest rate on the CCLP Senior Secured Notes, a portion of the proceeds of which were used to repay the balance outstanding under the CCLP Credit Agreement, and is expected to remain increased compared to prior year periods. Interest expense during 2018 and 2017 includes $2.1 million and $2.3 million, respectively, of finance cost amortization.
The Warrants are accounted for as a derivative liability in accordance with ASC 815 and therefore they are classified as a long-term liability on our consolidated balance sheet at their fair value. Increases (or decreases) in the fair value of the Warrants are generally associated with increases (or decreases) in the trading price of our common stock, resulting in adjustments to earnings for the associated valuation losses (gains), and resulting in future volatility of our earnings during the period the Warrants are outstanding.
The CCLP Preferred Units may be settled using a variable number of CCLP common units, and therefore the fair value of the CCLP Preferred Units is classified as a long-term liability on our consolidated balance sheet in accordance with ASC 480. Because the CCLP Preferred Units are convertible into CCLP common units at the option of the holder, the fair value of the CCLP Preferred Units will generally increase or decrease with the trading price of the CCLP common units, and this increase (decrease) in CCLP Preferred Unit fair value will be charged (credited) to earnings, as appropriate, resulting in future volatility of our earnings during the period the CCLP Preferred Units are outstanding.
In January 2017, our Completion Fluids & Products Division collected $12.8 million from a legal arbitration award, resulting in a credit to earnings. See Commitments and Contingencies - Litigation section below for additional discussion.
Consolidated other (income) expense, net, was $6.6 million of expense during the current year period compared to $1.2 million of expense during the prior year period, primarily due to $4.3 million of increased expense associated with the remeasurement of the contingent purchase price consideration for SwiftWater and
$3.5 million of increased expense related to the unamortized deferred financing costs charged to earnings as a result of the termination of the CCLP Credit Agreement. Partially offsetting these increases in expense were $1.4 million of increased foreign currency gains, $0.6 million of miscellaneous income, and $0.5 million of decreased other bank fees.
Our consolidated provision for income taxes during the first six months of 2018 is primarily attributable to taxes in certain foreign jurisdictions and Texas gross margin taxes. Our consolidated effective tax rate for the six month period ended June 30, 2018 of negative 12.1% was primarily the result of losses generated in entities for which no related tax benefit has been recorded. The losses generated by these entities do not result in tax benefits due to offsetting valuation allowances being recorded against the related net deferred tax assets. We establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.
The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. At June 30, 2018 and December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we made reasonable estimates of the effects and recorded provisional amounts. We will continue to make and refine our calculations as additional analysis is completed. The accounting for the tax effects of the Act will be completed in 2018 as provided by the U.S. Securities and Exchange Commission’s SAB No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act. We recognized an income tax expense of $54.1 million in the fourth quarter of 2017 associated with the impact of the Act, which was fully offset by a decrease in the valuation allowance previously recorded on our net deferred tax assets. As such, the Act resulted in no net tax expense in the fourth quarter of 2017. We have considered in our estimated annual effective tax rate for 2018 the impact of the statutory changes enacted by the Act, including reasonable estimates of those provisions effective for the 2018 tax year. Our estimate on Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), and IRC Section 163(j) interest limitation do not impact our effective tax rate for the six months ended June 30, 2018.

The decrease in Completion Fluids & Products Division revenues during the current year period compared to the prior year period was primarily due to $4.4 million of decreased service revenues, primarily due to a reduction in completion services activity associated with a 2017 TETRA CS Neptune completion fluid project. This decrease was offset by $3.8 million of increased product sales revenue, attributed to increased manufactured products sales, which were partially offset by reduced clear brine fluids ("CBF") and associated product sales revenues in the U.S. Gulf of Mexico. This decrease in CBF product sales was primarily due to the completion of the TETRA CS Neptune project during the prior year.
Completion Fluids & Products Division gross profit during the current year period decreased significantly compared to the prior year period primarily due to the profitability associated with the mix of CBF products and services, particularly for offshore completion fluids products. Completion Fluids & Products Division profitability in future periods will continue to be affected by the mix of its products and services, including the timing of TETRA CS Neptune completion fluid projects.
The Completion Fluids & Products Division reported a significant decrease in pretax earnings during the current year period compared to the prior year period due to the reduction in gross profit discussed above and due to the collection of an arbitration award of $12.8 million during January 2017 that was credited to earnings. Completion Fluids & Products Division administrative cost levels decreased compared to the prior year period, as $1.0 million of decreased salary and employee related expenses, $0.2 million of decreased bad debt expense, and $0.1 million of decreased general expenses were partially offset by $0.3 million of increased legal and professional fees. The Completion Fluids & Products Division continues to review opportunities to further reduce its administrative costs.

Water & Flowback Services Division revenues increased during the current year period compared to the prior year period primarily due to increased water management services activity. Water management and flowback services revenues increased $81.0 million during the current year period compared to the prior year period resulting from the impact of increased demand, reflecting the growth in the domestic onshore rig count. Approximately $36.6 million of the water management increase was generated from the operations of SwiftWater, which was acquired on February 28, 2018. Product sales revenue decreased by $5.6 million, due to an international equipment sale in the prior period.
The Water & Flowback Services Division reflected increased gross profit during the current year period compared to the prior year period, due to the increase in revenues and improving customer pricing levels. However, customer pricing continues to be challenging due to excess availability of equipment in certain markets. The Water & Flowback Services Division continues to monitor its cost structure, minimizing increased costs despite increasing activity levels, and looking to capture additional synergies following the SwiftWater acquisition.
The Water & Flowback Services Division reported pretax income compared to a pretax loss during the prior year period, primarily due to the improvement in gross profit described above. General and administrative expenses increased primarily due to the acquired SwiftWater operations, with increased wage and benefit related expenses of $3.3 million, increased professional fees of $0.3 million, and increased general expenses of $0.3 million. Other expense, net, was recorded during the current year period primarily due to $4.3 million of increased expense associated with the remeasurement of the contingent purchase price consideration for SwiftWater offset by increased foreign currency gains of $0.5 million.

Compression Division revenues increased during the current year period compared to the prior year period, primarily due to a $30.7 million increase in product sales revenues, due to a higher number of new compressor equipment sales compared to the prior year period. Demand for new compressor equipment continues to improve, and the current equipment sales backlog has increased significantly compared to the prior year period. In addition, current year revenues reflect a $13.8 million increase in service revenues from compression and aftermarket services operations. This increase in service revenues was primarily due to increasing demand for compression services, as reflected by increased compressor fleet utilization rates. Overall utilization of the Compression Division's compressor fleet has improved sequentially for seven consecutive quarterly periods, led by increased utilization of the high- and medium-horsepower fleet.
Compression Division gross profit increased during the current year period compared to the prior year due to increased revenues discussed above. The increased compressor fleet utilization rates have led to increases in customer contract pricing.
The Compression Division recorded an increased pretax loss despite increased gross profit discussed above. Interest expense increased compared to the prior year period, due to the higher interest rate from the CCLP Senior Secured Notes, which were issued in March 2018, compared to the previous CCLP Credit Agreement. Increased interest expense is expected to continue compared to the prior year periods. In addition, other (income) expense, net, reflected an increased expense primarily due to $3.5 million of unamortized deferred financing costs charged to earnings as a result of the termination of the CCLP Credit Agreement. In addition, the Series A Preferred fair value adjustment resulted in a charge to earnings during the current year period compared to a credit to earnings in the prior year period. General and administrative expense levels increased compared to the prior year period, due to increased salary and employee-related expenses, including equity compensation, of $1.0 million, increased other general expenses of $1.1 million, and increased professional fees of $0.3 million, partially offset by $0.2 million of decreased bad debt expense.

Loss before taxes | $ | (34,239 | ) |  | $ | (19,041 | ) |  | $ | (15,198 | ) |  | (79.8 | )%

Corporate Overhead pretax loss increased during the current year period compared to the prior year period, primarily due to the adjustment of the fair value of the outstanding Warrants liability that resulted in a $0.2 million charge to earnings compared to an $11.5 million credit to earnings during the prior year period. Corporate general and administrative expense increased primarily due to $2.2 million of increased professional fees, including $0.9 million of transaction costs, $0.8 million of increased general expenses, and $0.5 million of increased consulting fees. These increases were offset by $0.6 million of decreased salary and employee-related expenses, including equity compensation. In addition, interest expense increased due to increased borrowings. Other expense decreased due to reduced commitment and bank fees.
Liquidity and Capital Resources
We reported an increase in consolidated cash flows used in operating activities during the first six months of 2018 compared to the corresponding prior year period. This increase occurred despite the improved profitability of our operations, due to increased working capital needs largely due to the timing of payments of accounts payable. CCLP used $4.3 million of our consolidated operating cash flows during the six months ended June 30, 2018. We received $5.9 million of cash distributions from CCLP during the six months ended June 30, 2018 compared to $8.4 million during the corresponding prior year period. We believe that the capital structure steps we have taken during the past three years continue to support our ability to meet our financial obligations and fund
41

future growth as needed, despite current uncertain operating and financial markets. We and CCLP are in compliance with all covenants of our respective debt agreements as of June 30, 2018.
Our consolidated sources and uses of cash during the six months ended June 30, 2018 and 2017 are as follows:

| Six months ended June 30,
| 2018 |  | 2017
| (In Thousands)
Operating activities | $ | (12,127 | ) |  | $ | (561 | )
Investing activities | (106,347 | ) |  | (16,028 | )
Financing activities | 165,494 |  |  | 9,508 |

Because of the level of consolidated debt, we believe it is important to consider our capital structure and CCLP's capital structure separately, as there are no cross default provisions, cross collateralization provisions, or cross guarantees between CCLP's debt and TETRA's debt. (See Financing Activities section below for a discussion of the terms of our and CCLP's respective debt arrangements.) Our consolidated debt outstanding has a carrying value of approximately $810.7 million as of June 30, 2018. However, approximately $632.5 million of this consolidated debt balance is owed by CCLP and is serviced from the existing cash balances and cash flows of CCLP, $343.5 million of which is secured by certain of CCLP's assets. Through our common unit ownership interest in CCLP, which was approximately 37% as of June 30, 2018, and ownership of an approximately 1.6% general partner interest, we receive our share of the distributable cash flows of CCLP through its quarterly cash distributions. Approximately $51.4 million of the $70.2 million of the cash balance reflected on our consolidated balance sheet is owned by CCLP and is not accessible by us. As of June 30, 2018, and subject to compliance with the covenants and other provisions of the agreements that may limit borrowings under our Credit Agreement, we had availability of $132.2 million under our Credit Agreement. Following the issuance of the CCLP Senior Secured Notes, CCLP used a portion of the proceeds to repay the borrowings outstanding under CCLP's bank revolving credit facility, which was then terminated. In June 2018, CCLP entered into the CCLP New Credit Agreement. See CCLP Financing Activities below for further discussion.
Operating Activities
Consolidated cash flows used by operating activities totaled $12.1 million during the first six months of 2018 compared to $0.6 million during the corresponding prior year period, an increase of $11.6 million. Operating cash flows decrease d despite improved operating profitability due to the use of cash for working capital changes, particularly related to the timing of payments of accounts payable. We have taken steps to aggressively manage working capital, including increased collection efforts. We continue to monitor customer credit risk in the current environment and have historically focused on serving larger capitalized oil and gas operators and national oil companies.
Demand for the vast majority of our products and services is driven by oil and gas industry activity, which is impacted by oil and natural gas commodity prices. With the increase in crude oil prices in early 2018, operating plans and capital expenditure levels of many of our oil and natural gas customers have increased, benefiting certain of our operating segments with improved revenues and cash flows. The acquisition of SwiftWater during the six months ended June 30, 2018 is providing additional revenues and operating cash flows and is expected to continue to do so going forward. Domestic onshore rig counts have improved compared to early 2017, and this has resulted in improved cash provided by operating activities of our Water & Flowback Services Division. However, offshore and international rig count levels remain relatively unchanged. The increased capital expenditure activity of our Compression Division customers has resulted in increased demand for compression services and equipment, and increased revenues of our Compression Division. However, oil and natural gas prices are expected to continue to be volatile in the future, and if oil and gas industry activity levels decrease in the future, we expect that our levels of operating cash flows will be negatively affected. During early 2018, and despite increasing activity levels, our goal has been to minimize growth to our operating and administrative headcount and continue to maintain a low cost structure for our businesses.
42

As part of the sale of our Offshore Division in March 2018, Orinoco assumed all liabilities and obligations currently associated with our former Maritech subsidiary, including but not limited to all currently identified and any future identified Maritech decommissioning obligations.
Investing Activities
During the first six months of 2018, the total amount of our net cash utilized for investing activities was $106.3 million. The acquisition of SwiftWater included initial cash purchase consideration of $42.0 million, plus $1.0 million which was subsequently paid in August 2018 as a working capital adjustment. Total cash capital expenditures during the first six months of 2018 were $67.4 million. Our Completion Fluids & Products Division spent $1.8 million on capital expenditures during the first six months of 2018, the majority of which related to plant and facility additions. Our Water & Flowback Services Division spent $16.0 million on capital expenditures, primarily to add to its water management equipment fleet. Our Compression Division spent $47.4 million, primarily for growth capital expenditure projects to increase its compression fleet.
Generally, a majority of our planned capital expenditures has been related to identified opportunities to grow and expand certain of our existing businesses. However, certain of these planned expenditures have been, and may continue to be, postponed or canceled as we are reviewing all capital expenditure plans carefully in an effort to conserve cash. We currently have no long-term capital expenditure commitments. The deferral of capital projects could affect our ability to compete in the future. Excluding our Compression Division, we expect to spend approximately $45 to $55 million during 2018 on capital expenditures, primarily to expand our water management services equipment fleet. Our Compression Division expects to spend approximately $110 to $120 million on capital expenditures during 2018 to expand its compressor fleet in response to increased demand for compression services. The level of future growth capital expenditures depends on forecasted demand for our products and services. If the forecasted demand for our products and services during 2018 increases or decreases, the amount of planned expenditures on growth and expansion may be adjusted.
Financing Activities
During the first six months of 2018, the total amount of consolidated cash provided by financing activities was $165.5 million, primarily consisting of the proceeds from the issuance of the CCLP Senior Secured Notes, a portion of which was used to repay the CCLP Credit Agreement and provide additional funding for future capital expenditures, and borrowings under our Credit Agreement that were primarily used to fund the purchase of SwiftWater. To fund future capital and working capital requirements, we may supplement our existing cash balances and cash flow from operating activities with short-term borrowings, long-term borrowings, leases, equity issuances, and other sources of capital. We and CCLP are in compliance with all covenants of our respective credit and debt agreements as of June 30, 2018.
See CCLP Financing Activities below for discussion of the CCLP Preferred Units and CCLP's long-term debt.
Our Long-Term Debt
Our Bank Credit Facility. As of August 9, 2018, TETRA (excluding CCLP) had an outstanding balance on its revolving credit facility (as amended, the "Credit Agreement"), of $90.1 million, and had $6.8 million in letters of credit against the revolving credit facility, leaving a net availability, subject to compliance with our covenants and other provisions of the Credit Agreement that limit borrowings under the Credit Facility, of $103.1 million. The Credit Agreement, as amended, matures on September 30, 2019 and limits aggregate lender commitments to $200 million. Borrowings generally bear interest at the British Bankers Association LIBOR rate plus 2.50% to 4.25%, depending on one of our financial ratios. We pay a commitment fee ranging from 0.35% to 1.00% on unused portions of the facility. All obligations under the Credit Agreement and the guarantees of such obligations are secured by first-lien security interests in substantially all of our assets and the assets of our subsidiaries other than CCLP and its subsidiaries (limited, in the case of foreign subsidiaries, to 66% of the voting stock or equity interests of first-tier foreign subsidiaries). Such security interests are for the benefit of the lenders under the Credit Agreement as well as the holder of our 11% Senior Note on a pari passu basis. In addition, the Credit Agreement includes limitations on aggregate asset sales, individual acquisitions, and aggregate annual acquisitions, dispositions, and capital expenditures.
43

Our Credit Agreement contains customary covenants and other restrictions, including certain financial ratio covenants based on our levels of debt and interest cost compared to a defined measure of our operating cash flows over a twelve month period. The Credit Agreement requires us to maintain (i) a fixed charge coverage ratio that may not be less than 1.25 to 1 as of the end of any fiscal quarter; and (ii) a consolidated leverage ratio that may not exceed (a) 5.00 to 1 at the end of fiscal quarters ending during the period from and including March 31, 2017 through and including December 31, 2017, (b) 4.75 to 1 at the end of fiscal quarters ending March 31, 2018 and June 30, 2018, (c) 4.50 to 1 at the end of fiscal quarters ending September 30, 2018 and December 31, 2018, and (d) 4.00 to 1 at the end of each of the fiscal quarters thereafter. At June 30, 2018, our consolidated leverage ratio was 2.18 to 1 (compared to a 4.75 to 1 maximum allowed under the Credit Agreement). At June 30, 2018, our fixed charge coverage ratio was 2.87 to 1 (compared to a 1.25 to 1 minimum required under the Credit Agreement). Deterioration of these financial ratios could result in a default by us under the Credit Agreement that, if not remedied, could result in termination of the Credit Agreement and acceleration of any outstanding balances. Any such default could also result in a cross-default under our 11% Senior Note.
CCLP is an unrestricted subsidiary and is not a borrower or a guarantor under our Credit Agreement. Our Credit Agreement includes cross-default provisions relating to any other indebtedness (excluding indebtedness of CCLP) greater than a defined amount. Our Credit Agreement also contains a covenant that restricts us from paying dividends in the event of a default or if such payment would result in an event of default.
Our Senior Notes
Our Senior Note. Our 11% Senior Note is governed by the Note Purchase Agreement dated November 2015, as amended (the "Amended and Restated 11% Senior Note Agreement"), whereby we issued and sold $125.0 million in principal amount of our 11% Senior Note (the "11% Senior Note"). As of August 9, 2018, the aggregate principal amount outstanding of the 11% Senior Note is $125.0 million.
The 11% Senior Note bears interest at a fixed rate of 11.0% and matures on November 5, 2022. Interest on the 11% Senior Note is due quarterly on March 15, June 15, September 15, and December 15 of each year. We may prepay the 11% Senior Note, in whole or in part at a prepayment price equal to (i) prior to November 20, 2018, 100% of the principal amount so prepaid, plus accrued and unpaid interest and a “make-whole” prepayment amount, (ii) during the period commencing on November 20, 2018, and ending on November 19, 2019, 104% of the principal amount so prepaid, plus accrued and unpaid interest, (iii) during the period commencing on November 20, 2019 and ending on November 19, 2020, 102% of the principal amount so prepaid, plus accrued and unpaid interest, (iv) during the period commencing on November 20, 2020, and ending on November 19, 2021, 101% of the principal amount so prepaid, plus accrued and unpaid interest, and (v) on or after November 20, 2021, 100% of the principal amount so prepaid, plus accrued and unpaid interest.
The 11% Senior Note is guaranteed by substantially all of our wholly owned U.S. subsidiaries. The Amended and Restated 11% Senior Note Agreement contains customary covenants that limit our ability and the ability of certain of our restricted subsidiaries to, among other things: incur or guarantee additional indebtedness; incur or create liens; merge or consolidate or sell substantially all of our assets; engage in a different business; enter into transactions with affiliates; and make certain payments. In addition, the Amended and Restated 11% Senior Note Agreement requires us to maintain certain financial ratios, including a maximum leverage ratio (ratio of debt and letters of credit outstanding to a defined measure of earnings). The maximum leverage ratio is further defined in the Amended and Restated 11% Senior Note Agreement. Consolidated net earnings under the Amended and Restated 11% Senior Note Agreement is the aggregate of our net income (or loss) of our consolidated restricted subsidiaries, including cash dividends and distributions (not the return of capital) received from persons other than our consolidated restricted subsidiaries (such as CCLP) and after allowances for taxes for such period determined on a consolidated basis in accordance with U.S. generally accepted accounting principles ("GAAP"), excluding certain items more specifically described therein. CCLP and its subsidiaries are unrestricted subsidiaries and are not borrowers or guarantors under the Amended and Restated 11% Senior Note Agreement.

The Amended and Restated 11% Senior Note Agreement includes customary default provisions, as well as cross-default provisions relating to other indebtedness (excluding indebtedness of CCLP) greater than a defined amount. In addition, the Amended and Restated 11% Senior Note Agreement requires a minimum fixed charge coverage ratio at the end of any fiscal quarter of 1.25 to 1 and allows a maximum ratio of consolidated funded indebtedness at the end of any fiscal quarter of a defined measure of earnings ("EBITDA") of (a) 5.00 to 1 as of the end of any fiscal quarter ending during the period commencing March 31, 2017 and ending December 31, 2017, (b) 4.75 to 1 as of the end of any fiscal quarter ending March 31, 2018 and June 30, 2018 and (c) 4.50 to 1 as of the end of any fiscal quarter ending September 30, 2018 and December 31, 2018, and (d) 4.00 to 1 at the end of fiscal quarters ending thereafter. Pursuant to the Amended and Restated 11% Senior Note Agreement, the 11% Senior Note is secured by first-lien security interests in substantially all of our assets and the assets of our subsidiaries other than CCLP and its subsidiaries on a pari passu basis with the lenders under the Credit Agreement. See the above discussion of our Credit Agreement for a description of these security interests. The 11% Senior Note is pari passu in right of payment with all borrowings under the Credit Agreement and ranks at least pari passu in right of payment with all other outstanding indebtedness. We are in compliance with all covenants of the Amended and Restated 11% Senior Note Purchase Agreement as of June 30, 2018. At June 30, 2018, our ratio of consolidated funded indebtedness to EBITDA was 2.18 to 1 (compared to 4.75 to 1 maximum allowed under the Amended and Restated 11% Senior Note Agreement) and our fixed charge coverage ratio was 2.87 to 1 (compared to a 1.25 to 1 minimum required under the Amended and Restated 11% Senior Note Purchase Agreement). CCLP and its subsidiaries are unrestricted subsidiaries and are not borrowers or guarantors under our Amended and Restated 11% Senior Note Purchase Agreement.
CCLP Financing Activities
In March 2018, CCLP issued an aggregate $350.0 million of its CCLP Senior Secured Notes, and the net proceeds of $343.8 million were partially used to repay the remaining outstanding balance of $258.0 million under the CCLP Credit Agreement, which was then terminated. See below for a further discussion of the CCLP Senior Secured Notes. The remaining proceeds are being used to fund CCLP capital expenditures, including the increasing capital expenditures mentioned above that are needed in order to grow and maintain the capacity of CCLP's compressor and equipment fleet, as well as for general partnership needs.
CCLP Preferred Units. On August 8, 2016 and September 20, 2016, CCLP entered into Series A Preferred Unit Purchase Agreements (the “Unit Purchase Agreements”) with certain purchasers with regard to its issuance and sale in two private placements (the "Initial Private Placement" and "Subsequent Private Placement," respectively) of an aggregate of 6,999,126 of CSI Compressco LP Series A Convertible Preferred Units representing limited partner interests in CCLP (the “CCLP Preferred Units”) for a cash purchase price of $11.43 per CCLP Preferred Unit (the “Issue Price”), resulting in total 2016 net proceeds, after deducting certain offering expenses, of approximately $77.3 million. We purchased 874,891 of the CCLP Preferred Units at the aggregate Issue Price of $10.0 million.
In connection with the closing of the Initial Private Placement, CSI Compressco GP Inc (our wholly owned subsidiary) executed the Second Amended and Restated CCLP Partnership Agreement to, among other things, authorize and establish the rights and preferences of the CCLP Preferred Units. The CCLP Preferred Units are a new class of equity security that rank senior to all classes or series of equity securities of CCLP with respect to distribution rights and rights upon liquidation. We and the other holders of CCLP Preferred Units (each, a “CCLP Preferred Unitholder”) receive quarterly distributions, which are paid in kind in additional CCLP Preferred Units, equal to an annual rate of 11.00% of the Issue Price ($1.2573 per unit annualized) of the outstanding CCLP Preferred Units, subject to certain adjustments. The rights of the CCLP Preferred Units include certain anti-dilution adjustments, including adjustments for economic dilution resulting from the issuance of common units in the future below a set price.
A ratable portion of the CCLP Preferred Units has been, and will continue to be, converted into CCLP common units on the eighth day of each month over a period of thirty months that began in March 2017 (each, a “Conversion Date”), subject to certain provisions of the Second Amended and Restated CCLP Partnership Agreement that may delay or accelerate all or a portion of such monthly conversions. On each Conversion Date, a portion of the CCLP Preferred Units will convert into CCLP common units representing limited partner interests in CCLP in an amount equal to, with respect to each CCLP Preferred Unitholder, the number of CCLP Preferred Units held by such CCLP Preferred Unitholder divided by the number of Conversion Dates remaining, subject to adjustment described in the Second Amended and Restated CCLP Partnership Agreement, with the conversion
45

price (the "Conversion Price") determined by the trading prices of the common units over the prior month, among other factors, and as otherwise impacted by the existence of certain conditions related to the CCLP common units. The maximum aggregate number of CCLP common units that could be required to be issued pursuant to the conversion provisions of the CCLP Preferred Units is potentially unlimited; however, CCLP may, at its option, pay cash, or a combination of cash and CCLP common units, to the CCLP Preferred Unitholders instead of issuing CCLP common units on any Conversion Date, subject to certain restrictions as described in the Second Amended and Restated CCLP Partnership Agreement and the CCLP New Credit Agreement (defined below). Including the impact of paid in kind distributions of CCLP Preferred Units and conversions of CCLP Preferred Units into CCLP common units, the total number of CCLP Preferred Units outstanding as of June 30, 2018 was 4,458,803, of which we held 559,975.
Because the CCLP Preferred Units may be settled using a variable number of CCLP common units, the fair value of the CCLP Preferred Units is classified as a long-term liability on our consolidated balance sheet in accordance with ASC 480 "Distinguishing Liabilities and Equity." The fair value of the CCLP Preferred Units as of June 30, 2018 was $45.6 million. Changes in the fair value during each quarterly period, if any, are charged or credited to earnings in the accompanying consolidated statements of operations. Charges or credits to earnings for changes in the fair value of the CCLP Preferred Units, along with the interest expense for the accrual and payment of paid-in-kind distributions associated with the CCLP Preferred Units, are non-cash charges and credits associated with the CCLP Preferred Units.
In addition, the CCLP Unit Purchase Agreements include certain provisions regarding change of control, transfer of CCLP Preferred Units, indemnities, and other matters. The CCLP Unit Purchase Agreements contain customary representations, warranties and covenants of CCLP and the purchasers.
CCLP Bank Credit Facilities. On June 29, 2018, CCLP and two of its wholly owned subsidiaries (collectively the "CCLP Borrowers"), and certain of its wholly owned subsidiaries named therein as guarantors (the "CCLP New Credit Agreement Guarantors"), entered into a Loan and Security Agreement (the "CCLP New Credit Agreement") with the lenders thereto (the "Lenders"), and Bank of America, N.A., in its capacity as administrative agent, collateral agent, letter of credit issuer, and swing line lender. All of the CCLP Borrowers' obligations under the CCLP New Credit Agreement are guaranteed by certain of their existing and future domestic subsidiaries. The CCLP New Credit Agreement includes a maximum credit commitment of $50.0 million available for loans, letters of credit (with a sublimit of $25.0 million) and swingline loans (with a sublimit of $5.0 million). Such maximum credit commitment may be increased by $25.0 million in accordance with the terms and conditions of the CCLP New Credit Agreement.
The CCLP Borrowers may borrow funds under the CCLP New Credit Agreement to pay fees and expenses related to the CCLP New Credit Agreement and for the Borrower's ongoing working capital needs and for general partnership purposes. The revolving loans under the CCLP New Credit Agreement may be voluntarily prepaid, in whole or in part, without premium or penalty, subject to breakage or similar costs. The maturity date of the CCLP New Credit Agreement is June 29, 2023. As of June 30, 2018, no balance was outstanding under the CCLP New Credit Agreement. As of August 8, 2018,CCLP has no balance outstanding under the CCLP New Credit Agreement and $5.7 million letters of credit, leaving availability under the CCLP New Credit Agreement of $44.3 million.
Borrowings under the CCLP New Credit Agreement will bear interest at a rate per annum equal to, at the option of the CCLP Borrowers, either (i) London InterBank Offered Rate (“LIBOR”) (adjusted to reflect any required bank reserves) for an interest period equal to 30, 60, 90, 180 or 360 days (as selected by the CCLP Borrowers, subject to availability and with the consent of the Lenders for 360 days) plus a margin based on average daily excess availability or (ii) a base rate plus a margin based on average daily excess availability; such base rate shall be determined by reference to the highest of (a) the prime rate of interest announced from time to time by Bank of America, N.A., (b) the Federal Funds Rate (as defined in the CCLP New Credit Agreement) rate plus 0.5% per annum and (c) LIBOR (adjusted to reflect any required bank reserves) for a 30-day interest period on such day plus 1.0% per annum. Initially, from June 29, 2018 until the delivery of the financial statements for the fiscal quarter ending December 31, 2018, LIBOR-based loans will have an applicable margin of 2.00% per annum and base-rate loans will have an applicable margin of 1.00% per annum; thereafter, the applicable margin will range between 1.75% and 2.25% per annum for LIBOR-based loans and 0.75% and 1.25% per annum for base-rate loans, according to average daily excess availability when financial statements are delivered. In addition to paying interest on outstanding principal under the CCLP New Credit Agreement, the CCLP Borrowers are required to pay a commitment fee in respect of the unutilized commitments thereunder, initially at the rate of 0.375% per annum until the delivery of the financial statements for the fiscal quarter ending September 30, 2018 and thereafter at the applicable rate ranging from 0.250% to 0.375% per annum, paid quarterly in arrears based on utilization of the
46

commitments under the CCLP New Credit Agreement. The CCLP Borrowers are also required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans and fronting fees.
The CCLP New Credit Agreement contains certain affirmative and negative covenants, including covenants that restrict the ability of the CCLP Borrowers, the CCLP New Credit Agreement Guarantors, and certain of their subsidiaries to take certain actions including, among other things and subject to certain significant exceptions, the incurrence of debt, the granting of liens, the making of investments, entering into transactions with affiliates, the payment of dividends, and the sale of assets. The CCLP New Credit Agreement also contains a requirement that the CCLP Borrowers comply, during certain periods, with a fixed charge coverage ratio of 1.0 to 1.0.
All obligations under the CCLP New Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first priority security interest for the benefit of the Lenders in the CCLP Borrowers’ and the CCLP New Credit Agreement Guarantors’ present and future accounts receivable, inventory and related assets, and proceeds of the foregoing (the “CCLP ABL Collateral”).
CCLP Senior Secured Notes. On March 8, 2018, CCLP entered into the Purchase Agreement (the “Purchase Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated as representative of the initial purchasers listed in Schedule A thereto (collectively, the “Initial Purchasers”), pursuant to which the CCLP Issuers agreed to issue and sell to the Initial Purchasers $350.0 million aggregate principal amount of the CCLP Issuers’ 7.50% Senior Secured First Lien Notes due 2025 (the "CCLP Senior Secured Notes") (the "CCLP Offering") pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). As of August 8, 2018, $350.0 million in aggregate principal amount of our 7.50% Senior Secured Notes are outstanding.
The CCLP Issuers closed the Offering on March 22, 2018. The CCLP Senior Secured Notes were issued at par for net proceeds of approximately $343.8 million, after deducting certain financing costs. CCLP used a portion of the net proceeds to repay in full and terminate CCLP's existing bank Credit Agreement and plans to use the remainder for general partnership purposes, including the expansion of its compression fleet. The CCLP Senior Secured Notes are jointly and severally, and fully and unconditionally, guaranteed (the "Guarantees" and, together with the CCLP Senior Secured Notes, the "CCLP Senior Secured Note Securities") on a senior secured basis initially by each of CCLP's domestic restricted subsidiaries (other than CSI Compressco Finance Inc., certain immaterial subsidiaries and certain other excluded domestic subsidiaries) and are secured by a first-priority security interest in substantially all of the CCLP Issuers' and the Guarantors' assets (other than certain excluded assets, including the CCLP ABL Collateral) (the "Collateral") as collateral security for their obligations under the CCLP Senior Secured Notes, subject to certain permitted encumbrances and exceptions. On the closing date, we entered into an indenture (the "Indenture") by and among the Obligors and U.S. Bank National Association, as trustee with respect to the CCLP Senior Secured Note Securities. The CCLP Senior Secured Notes accrue interest at a rate of 7.50% per annum. Interest on the CCLP Senior Secured Notes are payable semi-annually in arrears on April 1 and October 1 of each year, beginning October 1, 2018. The CCLP Senior Secured Notes are scheduled to mature on April 1, 2025. In connection with the CCLP Offering, CCLP incurred total financing costs of $6.7 million related to the CCLP Senior Secured Notes. These costs are deferred, netting against the carrying value of the amount outstanding.
On and after April 1, 2021, CCLP may redeem all or a part of the CCLP Senior Secured Notes, from time to time, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest thereon to, but not including, the applicable redemption date, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the 12-month period beginning on April 1 of the years indicated below:

Date |  | Price
2021 |  | 105.625%
2022 |  | 103.750%
2023 |  | 101.875%
2024 |  | 100.000%

47

In addition, at any time and from time to time before April 1, 2021, CCLP may, at its option, redeem all or a portion of the CCLP Senior Secured Notes at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium (as defined in the Indenture) with respect to the CCLP Senior Secured Notes plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date, subject to the rights of holders of the CCLP Senior Secured Notes on the relevant record date to receive interest due on the relevant interest payment date.
Prior to April 1, 2021, CCLP may on one or more occasions redeem up to 35% of the principal amount of the CCLP Senior Secured Notes with an amount of cash not greater than the amount of the net cash proceeds from one or more equity offerings at a redemption price equal to 107.500% of the principal amount of the CCLP Senior Secured Notes to be redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date, provided that (a) at least 65% of the aggregate principal amount of the CCLP Senior Secured Notes originally issued on the issue date (excluding notes held by CCLP and its subsidiaries) remains outstanding after each such redemption; and (b) the redemption occurs within 180 days after the date of the closing of the equity offering.
If CCLP experiences certain kinds of changes of control, each holder of CCLP Senior Secured Notes will be entitled to require us to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that holder’s CCLP Senior Secured Notes pursuant to an offer on the terms set forth in the Indenture. CCLP will offer to make a cash payment equal to 101% of the aggregate principal amount of the CCLP Senior Secured Notes repurchased plus accrued and unpaid interest, if any, on the CCLP Senior Secured Notes repurchased to the date of repurchase, subject to the rights of holders of the CCLP Senior Secured Notes on the relevant record date to receive interest due on the relevant interest payment date.
The Indenture contains customary covenants restricting CCLP ability and the ability of CCLP restricted subsidiaries to: (i) pay distributions on, purchase or redeem CCLP common units or purchase or redeem any CCLP subordinated debt; (ii) incur or guarantee additional indebtedness or issue certain kinds of preferred equity securities; (iii) create or incur certain liens securing indebtedness; (iv) sell assets, including dispositions of the Collateral; (v) consolidate, merge or transfer all or substantially all of its assets; (vi) enter into transactions with affiliates; and (vii) enter into agreements that restrict distributions or other payments from its restricted subsidiaries to CCLP. These covenants are subject to a number of important limitations and exceptions, including certain provisions permitting CCLP, subject to the satisfaction of certain conditions, to transfer assets to certain of CCLP unrestricted subsidiaries. Moreover, if the CCLP Senior Secured Notes receive an investment grade rating from at least two rating agencies and no default has occurred and is continuing under the Indenture, many of the restrictive covenants in the Indenture will be terminated. The Indenture also contains customary events of default and acceleration provisions relating to such events of default, which provide that upon an event of default under the Indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding CCLP Senior Secured Notes may declare all of the CCLP Senior Secured Notes to be due and payable immediately.
On March 22, 2018, CCLP, the grantors named therein, the Trustee and U.S. Bank National Association, as the collateral trustee (the “Collateral Trustee”), entered into a collateral trust agreement (the “Collateral Trust Agreement”) pursuant to which the Collateral Trustee will receive, hold, administer, maintain, enforce and distribute the proceeds of all of its liens upon the collateral for the benefit of the current and future holders of the CCLP Senior Secured Notes and any future priority lien obligations, if any.
CCLP Senior Notes. The obligations under the CCLP 7.25% Senior Notes (the "CCLP Senior Notes") are jointly and severally and fully and unconditionally, guaranteed on a senior unsecured basis by each of CCLP’s domestic restricted subsidiaries (other than CSI Compressco Finance) that guarantee CCLP’s other indebtedness (the "Guarantors" and together with the Issuers, the "Obligors"). The CCLP Senior Notes and the subsidiary guarantees thereof (together, the "CCLP Senior Note Securities") were issued pursuant to an indenture described below. As of August 8, 2018, $295.9 million in aggregate principal amount of the CCLP Senior Notes are outstanding.
The Obligors issued the CCLP Senior Note Securities pursuant to the Indenture dated as of August 4, 2014 (the "CCLP Senior Note Indenture") by and among the Obligors and U.S. Bank National Association, as trustee (the "Trustee"). The CCLP Senior Notes accrue interest at a rate of 7.25% per annum. Interest on the CCLP Senior Notes is payable semi-annually in arrears on February 15 and August 15 of each year. The CCLP Senior Notes are scheduled to mature on August 15, 2022.
48

The CCLP Senior Note Indenture contains customary covenants restricting CCLP’s ability and the ability of its restricted subsidiaries to: (i) pay dividends and make certain distributions, investments and other restricted payments; (ii) incur additional indebtedness or issue certain preferred shares; (iii) create certain liens; (iv) sell assets; (v) merge, consolidate, sell or otherwise dispose of all or substantially all of its assets; (vi) enter into transactions with affiliates; and (vii) designate its subsidiaries as unrestricted subsidiaries under the CCLP Senior Note Indenture. The CCLP Senior Note Indenture also contains customary events of default and acceleration provisions relating to such events of default, which provide that upon an event of default under the CCLP Senior Note Indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the CCLP Senior Notes then outstanding may declare all amounts owing under the CCLP Senior Notes to be due and payable. CCLP is in compliance with all covenants of the CCLP Senior Note Purchase Agreement as of June 30, 2018.
Other Sources and Uses
In addition to the aforementioned revolving credit facility, we and CCLP fund our respective short-term liquidity requirements from cash generated by our respective operations, leases, and from short-term vendor financing. Should additional capital be required, we believe that we have the ability to raise such capital through the issuance of additional debt or equity securities. However, instability or volatility in the capital markets at the times we need to access capital may affect the cost of capital and the ability to raise capital for an indeterminable length of time.
TETRA's Credit Agreement, as amended, matures in September 2019, TETRA's 11% Senior Note matures in November 2022, the CCLP Senior Notes mature in August 2022, the CCLP Senior Secured Notes mature in March 2025, and the CCLP New Credit Agreement matures in June 2023. The replacement of these capital sources at similar or more favorable terms is not certain. If it is necessary to issue additional equity to fund our capital needs, additional dilution to our common stockholders will occur.
Although near-term growth plans pursuant to our long-term growth strategy have resumed, they are being reviewed carefully and are subject to our continuing efforts to conserve cash. CCLP has also increased its growth capital expenditure activity in response to increased demand for compression services. CCLP's long-term growth objectives are funded from its available cash, other borrowings, and cash generated from the issuance of common or preferred units.
On March 23, 2016, we filed a universal shelf Registration Statement on Form S-3 with the Securities and Exchange Commission ("SEC"). On April 13, 2016, the Registration Statement on Form S-3 was declared effective by the SEC. Pursuant to this registration statement, we have the ability to sell debt or equity securities in one or more public offerings up to an aggregate public offering price of $164.4 million. This shelf registration statement currently provides us additional flexibility with regard to potential financings that we may undertake when market conditions permit or our financial condition may require.
As part of long-term strategic growth plans, we and CCLP evaluate opportunities to acquire businesses and assets that may require the payment of cash. Such acquisitions may be funded with existing cash balances, funds under credit facilities, or cash generated from the issuance of equity or debt securities.
The Second Amended and Restated Partnership Agreement of CCLP requires that within 45 days after the end of each quarter, CCLP distribute all of its available cash, as defined in the Second Amended and Restated Partnership Agreement, to its common unitholders of record on the applicable record date. During the six months ended June 30, 2018, CCLP distributed $14.9 million in cash, including $9.0 million to its public unitholders. The amount of quarterly distributions is determined based on a variety of factors, including estimates of CCLP's cash needs to fund its future operating, investing, and debt services requirements. There can be no assurance that quarterly distributions from CCLP will increase from this amount per unit, or that there will not be future decreases in the amount of distributions going forward.
Off Balance Sheet Arrangements
As of June 30, 2018, we had no “off balance sheet arrangements” that may have a current or future material effect on our consolidated financial condition or results of operations.
49

Commitments and Contingencies
Litigation
We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.
On March 18, 2011, we filed a lawsuit in the Circuit Court of Union County, Arkansas, asserting claims of professional negligence, breach of contract and other claims against the engineering firm we hired for engineering design, equipment, procurement, advisory, testing and startup services for our El Dorado, Arkansas chemical production facility. The engineering firm disputed our claims and promptly filed a motion to compel the matter to arbitration. After a lengthy procedural dispute in Arkansas state court, arbitration proceedings were initiated on November 15, 2013. Ultimately, on December 16, 2016, the arbitration panel ruled in our favor, declared us as the prevailing party, and awarded us a total net amount of $12.8 million. We received full payment of the $12.8 million final award on January 5, 2017.
Other Contingencies
During 2011, in connection with the sale of a significant majority of Maritech's oil and gas producing properties, the buyers of the properties assumed the associated decommissioning liabilities pursuant to the purchase and sale agreements. In March 2018, we closed the Maritech Asset Purchase Agreement with Orinoco that provided for the purchase by Orinoco of the Maritech Properties. Also in March 2018, we finalized the Maritech Equity Purchase Agreement with Orinoco that provided for the purchase by Orinoco of the Maritech Equity Interests. As a result of these transactions, we have effectively exited the businesses of our Offshore Services and Maritech segments and Orinoco assumed all of Maritech's remaining abandonment and decommissioning obligations.

These excluded amounts include approximately $1.2 million of liabilities under FASB Codification Topic 740, “Accounting for Uncertainty in Income Taxes,” as we are unable to reasonably estimate the ultimate amount or timing of tax settlements. These excluded amounts also include approximately $45.6 million of liabilities related to the CCLP Series A Convertible Preferred Units. The preferred units are expected to be serviced and satisfied with non-cash paid-in-kind distributions and conversions to CCLP common units. See "Note E – CCLP Series A Convertible Preferred Units," in the Notes to Consolidated Financial Statements for further discussion.

Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017, those set forth in Item 1A "Risk Factors" in Part II of this Quarterly Report on Form 10-Q, and as included in our other filings with the U.S. Securities and Exchange Commission (“SEC”), which are available free of charge on the SEC website at www.sec.gov.

The risks and uncertainties referred to above are generally beyond our ability to control and we cannot predict all the risks and uncertainties that could cause our actual results to differ from those indicated by the forward-looking statements. If any of these risks or uncertainties materialize, or if any of the underlying assumptions prove incorrect, actual results may vary from those indicated by the forward-looking statements, and such variances may be material.
All subsequent written and oral forward-looking statements made by or attributable to us or to persons acting on our behalf are expressly qualified in their entirety by reference to these risks and uncertainties. You should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to update or revise any forward-looking statements we may make, except as may be required by law.
Item 3. Quantitative and Qualitative Disclosures about Market Risk.
Market risk is the risk of loss arising from adverse changes in market rates and prices. For a discussion of our indirect exposure to fluctuating commodity prices, please read “Risk Factors — Certain Business Risks” in our Annual Report on Form 10-K filed with the SEC on March 5, 2018. We depend on U.S. and international demand for and production of oil and natural gas, and a reduction in this demand or production could adversely affect the demand or the prices we charge for our services, which could cause our revenues and operating cash flows to decrease in the future. We do not currently hedge, and do not intend to hedge, our indirect exposure to fluctuating commodity prices.

Exchange Rate Risk
As of June 30, 2018, there have been no material changes pertaining to our exchange rate exposures as disclosed in our Form 10-K for the year ended December 31, 2017.
Item 4. Controls and Procedures.
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2018, the end of the period covered by this quarterly report.
As discussed above in this Quarterly Report on Form 10-Q, on February 28, 2018, we completed the acquisition of SwiftWater. We are currently integrating SwiftWater into our internal control over financial reporting processes. In executing this integration, we are analyzing, evaluating, and, where necessary, making changes in controls and procedures related to the SwiftWater business, which we expect to be completed in fiscal year 2019. We expect to exclude SwiftWater from our assessment of internal control over financial reporting as of December 31, 2018. Total assets of SwiftWater represented approximately 6% of our consolidated total assets as of June 30, 2018, and SwiftWater's revenues following the February 28, 2018 acquisition date represented approximately 11% and 8% of our consolidated revenues for the three and six month period ended June 30, 2018, respectively.
Other than the changes described above, there were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended June 30, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II
OTHER INFORMATION
Item 1. Legal Proceedings.
We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.

Environmental Proceedings
One of our subsidiaries, TETRA Micronutrients, Inc. ("TMI"), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the "Consent Order"), with regard to the Fairbury facility. TMI is liable for ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility. While the outcome cannot be predicted with certainty, management does not consider it reasonably possible that a loss in excess of any amounts accrued has been incurred or is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.
