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, offshore rig cooling, compression services and equipment, and selected offshore services including well plugging and abandonment, decommissioning, and diving. We also have a limited domestic oil and gas production business. We were incorporated in Delaware in 1981 and are composed of five reporting segments organized into four divisions – Fluids, Production Testing, Compression, and Offshore. 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.
The consolidated financial statements include the accounts of our wholly owned subsidiaries. We consolidate the financial statements of CSI Compressco LP and its subsidiaries ("CCLP") as part of our Compression segment. We control CCLP through our ownership of its general partner. The public ownership share of CCLP's net assets and earnings is presented as noncontrolling interest in our consolidated financial statements. Our interests in oil and gas properties are proportionately consolidated. 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 September 30, 2015 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2015.
As a result of CCLP's acquisition of Compressor Systems, Inc. ("CSI") on August 4, 2014, our Compression Division's operations have significantly expanded. See Note B - Acquisitions for further discussion.
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, 2014, and notes thereto included in our Annual Report on Form 10-K, which we filed with the SEC on March 2, 2015.
Certain previously reported financial information has been reclassified to conform to the current year period’s presentation. The impact of such reclassifications was not significant to the prior year period’s overall presentation. These reclassifications include the final allocation of the purchase price of CSI. See Note B - Acquisitions for further discussion.
Beginning in 2014, and continuing into late-2015, significant decreases in oil and natural gas commodity prices lowered the capital expenditure and operating plans of many of our customers, creating uncertainty regarding the expected demand for many of our products and services and the resulting cash flows from operating activities for the foreseeable future. In addition, the availability of new borrowings in the current capital markets is more limited and costly. Accordingly, we continue to implement cost reduction measures designed to lower our cost structure in the current market environment, and have taken other steps to improve our operating cash flows. As a result of the steps taken to improve operating cash flows, we believe that despite the current industry environment and activity levels we will have adequate liquidity to fund our operations and debt obligations and maintain compliance with debt covenants through September 30, 2016. In addition, as further discussed in Note C - Long-Term Debt and Other Borrowings, on November 5, 2015, we entered into a Note Purchase Agreement (the “2015 Senior Note Purchase Agreement”) with GSO Tetra Holdings LP, an unrelated third party. Pursuant to the 2015 Senior Note Purchase Agreement, we agreed to issue and sell $125.0 million in aggregate principal amount of our 11.0% Senior Notes due November 5, 2022 (the “Series 2015 Senior Notes”). In addition, on November 5, 2015, we announced the commencement of a tender offer (the “Tender Offer”) to purchase for cash up to $25.0 million aggregate principal amount of the outstanding Series 2010-A Senior Notes and Series 2010-B Senior Notes (collectively, the “2010 Senior Notes”). Also on November 5, 2015, we entered into an amendment to the Note Purchase Agreement, conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, that provides for the extension of the maturity date of our $50.0 million Senior Secured Notes from April 1, 2017 to
6

April 1, 2019. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. Thereafter, we are to apply any remaining portion of the proceeds, together with other funds (to the extent necessary) to (i) pay the purchase price for 2010 Senior Notes accepted for purchase pursuant to the Tender Offer (defined above), (ii) prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016 and (iii) pay fees and expenses associated with the transactions contemplated under the 2015 Senior Note Purchase Agreement. Following the completion of these transactions, we will have repaid and extended the maturity dates of a significant amount of TETRA's total long-term debt. In addition, we are considering certain additional financing transactions with a view of generating additional cash to reduce the amount of our outstanding borrowings under our Credit Agreement, repay or refinance additional amounts of our senior notes, and generate additional liquidity.
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires us 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 and expenses during the reporting period. For further discussion of fair value measurements in connection with the allocation of the purchase price of the CSI acquisition, see Note B - Acquisitions. Actual results could differ from those estimates, and such differences could be material.
Cash Equivalents
We consider all highly liquid cash investments, with a maturity of three months or less when purchased, to be cash equivalents.
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 reported on our balance sheet as of September 30, 2015 consists primarily of escrowed cash associated with our July 2011 purchase of a heavy lift derrick barge. The escrowed cash will be released to the sellers or us in accordance with the terms of the escrow agreement.
Inventories
Inventories are stated at the lower of cost or market value. The cost of finished goods, raw materials, and parts and supplies are determined using the weighted average method. The cost of work in progress is determined using the specific identification method.
Significant components of inventories as of September 30, 2015, and December 31, 2014, are as follows:

| September 30, 2015 |  | December 31, 2014
| (In Thousands)
Finished goods | $ | 59,261 |  |  | $ | 62,188 |
Raw materials | 3,528 |  |  | 5,005 |
Parts and supplies | 42,031 |  |  | 51,229 |
Work in progress | 40,637 |  |  | 70,935 |
Total inventories | $ | 145,457 |  |  | $ | 189,357 |

Finished goods inventories include newly manufactured clear brine fluids as well as recycled brines that are repurchased from certain customers. 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. We provide a reserve for estimated unrealizable inventory equal to the difference between the cost of inventory and its estimated 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 September 30, |  | Nine Months Ended September 30,
| 2015 |  | 2014 |  | 2015 |  | 2014
| (In Thousands)
Number of weighted average common shares outstanding | 79,219 |  |  | 78,683 |  |  | 79,098 |  |  | 78,506 |
Assumed exercise of stock awards | 573 |  |  | — |  |  | 357 |  |  | — |
Average diluted shares outstanding | 79,792 |  |  | 78,683 |  |  | 79,455 |  |  | 78,506 |

For the three and nine month periods ended September 30, 2015, the average diluted shares outstanding excludes the impact of 3,752,879 and 3,581,111, respectively, of average outstanding stock awards that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive. For the three and nine month periods ended September 30, 2014, the average diluted shares outstanding excludes the impact of all outstanding stock awards, as the inclusion of these shares would have been antidilutive due to the net losses recorded during the periods.
Services and Rentals Revenues and Costs
A portion of our services and rentals revenues consist of lease rental income pursuant to operating lease arrangements for compressors and other equipment assets. For the three and nine month periods ended September 30, 2015 and 2014, the following operating lease revenues and associated costs were included in services and rentals revenues and cost of services and rentals, respectively, in the accompanying consolidated statements of operations.

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2015 |  | 2014 |  | 2015 |  | 2014
| (In Thousands)
Rental revenue | $ | 31,978 |  |  | $ | 31,842 |  |  | $ | 115,476 |  |  | $ | 42,686 |
Cost of rental revenue | $ | 10,981 |  |  | $ | 15,692 |  |  | $ | 53,417 |  |  | $ | 20,955 |

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 currency 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 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 Expense and totaled $(0.5) million and $(2.7) million during the three and nine month periods ended September 30, 2015, respectively, and $(0.6) million and $(1.5) million during the three and nine months ended September 30, 2014 , respectively.
Income Taxes
Our consolidated effective tax rates for the three and nine month periods ended September 30, 2015, include the effects of changes in our expected valuation allowance at the end of 2015 related to our deferred tax assets, such as our U.S. net operating loss carryforward. In 2014, we increased our valuation allowance, primarily on our U.S. deferred tax assets after considering all available positive and negative evidence related to the realizability of our deferred tax assets. Similarly, after considering updated evidence related to the deferred tax assets of one of our international operations, during the third quarter of 2015 we also increased our valuation allowance for this international deferred tax asset. Included in our deferred tax assets are net operating loss
8

carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.
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 generally accepted accounting principles, 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 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). In addition, we utilize fair value measurements in the initial recording of our decommissioning and other asset retirement obligations. Fair value measurements may also be utilized on a nonrecurring basis, such as for the impairment of long-lived assets, including goodwill (a level 3 fair value measurement). The fair value of our financial instruments, which include cash, restricted cash, accounts receivable, short-term borrowings, and long-term debt pursuant to our bank credit agreements, approximate their carrying amounts. The aggregate fair values of our long-term Senior Notes and Senior Secured Notes (as such terms are herein defined) at September 30, 2015 and December 31, 2014, were approximately $242.6 million and $310.7 million, respectively, compared to carrying amounts of $265.0 million and $305.0 million, respectively, as current interest rates on those dates were different than the stated interest rates on the Senior Notes and Senior Secured Notes. The fair values of the publicly tradable CCLP Senior Notes (as herein defined) at September 30, 2015 were approximately $287.0 million (a level 2 fair value measurement). Prior to the closing of a public exchange offer on July 20, 2015, and as of December 31, 2014, the fair value of the CCLP Senior Notes was approximately $354.9 million. The fair values of the CCLP Senior Notes compared to a face amount of approximately $350.0 million (See Note C - Long-Term Debt and Other Borrowings, for further discussion), as current rates on those dates were different from the stated interest rates on the CCLP Senior Notes. We calculate the fair values of our Senior Notes, our Senior Secured Notes and the CCLP Senior Notes as of September 30, 2015 and December 31, 2014 (excluding the CCLP Senior Notes as of September 30, 2015, which are publicly tradable) internally, using current market conditions and average cost of debt (a level 2 fair value measurement).
We calculate the fair value of the liability for our contingent purchase price consideration obligation in accordance with the WIT Water Transfer, LLC (acquired in January 2014 and doing business as TD Water Transfer) share purchase agreement based upon a probability weighted calculation using the actual and anticipated earnings of the acquired operations (a level 3 fair value measurement). The fair value of the liability for the TD Water Transfer contingent purchase price consideration at September 30, 2015, was $0. We also utilize fair value measurements on a recurring basis in the accounting for our foreign currency forward sale 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). A summary of these fair value measurements as of September 30, 2015 and December 31, 2014, is as follows:

New Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance 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. This ASU was originally scheduled to be effective for the first quarter in fiscal 2017, however, in July 2015, the FASB voted to approve a one year deferral of effectiveness of the ASU, to annual periods beginning after December 15, 2017, and interim periods within those years, under either full or modified retrospective adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements - Going Concern” (Topic 250). The ASU provides guidance on management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and in certain circumstances to provide related footnote disclosures. The ASU is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
In January 2015, the FASB issued ASU No. 2015-01, “Income Statements - Extraordinary and Unusual Items” (Sub-Topic 225-20), which eliminates from U.S. GAAP the concept of extraordinary items. The guidance eliminates the separate presentation of extraordinary items on the income statement, net of tax and the related earnings per share, but does not affect the requirement to disclose material items that are unusual in nature or occurring infrequently. The ASU is effective for the annual period beginning after December 15, 2015 and interim periods within those annual periods, with early adoption permitted, and may be applied prospectively or retrospectively. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
10

In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs”. The ASU requires entities that have historically presented debt issuance costs as an asset to present those costs as a direct deduction from the carrying amount of the related debt liability. This presentation will result in the debt issuance costs being presented the same way debt discounts have historically been handled. The ASU does not change the recognition, measurement, or subsequent measurement guidance for debt issuance costs. The ASU is effective for the annual period beginning after December 15, 2015 and interim periods within those annual periods and is to be applied retrospectively. Early adoption is permitted. We plan to adopt this change retrospectively, and do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory” (Topic 330), which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. The ASU requires entities to compare the cost of inventory to one measure - net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The ASU is effective for the annual period beginning after December 15, 2015 and interim periods within those annual periods, with early adoption permitted, and is to be applied prospectively. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
In September 2015, the FASB issued ASU No. 2015-16, “Simplifying the Accounting for Measurement Period Adjustments” (Topic 805), which requires that adjustments to provisional amounts identified during the measurement period of a business combination be recognized in the reporting period in which those adjustments are determined, including the effect on earnings, if any, calculated as if the accounting had been completed at the acquisition date. The ASU eliminates the previous requirement to retrospectively account for such adjustments and requires additional disclosures related to the income statement effects of adjustments to provisional amounts identified during the measurement period. The ASU is effective for the annual period beginning after December 15, 2015 and interim periods within those annual periods, with early adoption permitted, and is to be applied prospectively. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
NOTE B – ACQUISITIONS
Acquisition of Compressor Systems, Inc.
On August 4, 2014, a subsidiary of CCLP acquired all of the outstanding capital stock of CSI for $825.0 million cash (the "CSI Acquisition"). Prior to the acquisition, CSI owned one of the largest fleets of natural gas compressor packages in the United States. Headquartered in Midland, Texas, CSI fabricates, sells, and maintains natural gas compressors and provides a full range of compression products and services that covers compression needs throughout the entire natural gas production and transportation cycle to natural gas and oil producing clients. CSI derives revenues through three primary business lines: compression and related services, equipment and parts sales, and aftermarket services. Strategically, the acquisition affords the Compression Division the opportunity to capture significant synergies associated with its product and service offerings and its fabrication operations, to further penetrate new and existing markets, and to achieve administrative efficiencies and other strategic benefits.
Our allocation of the purchase price to the estimated fair value of CSI's net assets is as follows (in thousands):
11

Current assets | $ | 101,411 |
Property and equipment | 571,706 |
Intangible assets | 68,000 |
Goodwill | 161,387 |
Total assets acquired | 902,504 |
Current liabilities | 77,504 |
Total liabilities assumed | 77,504 |
Net assets acquired | $ | 825,000 |

The allocation of purchase price includes approximately $161.4 million allocated to deductible goodwill recorded, and is supported by the strategic benefits discussed above that are expected to be generated from the acquisition. Adjustments to the allocation of purchase price affecting inventory, property, plant, and equipment, intangible assets, and other current assets and liabilities have been reflected in the accompanying consolidated balance sheets as of September 30, 2015 and December 31, 2014. The adjustment to the previously presented goodwill balance as of December 31, 2014 was $0.1 million. These adjustments to the allocation of purchase price for long-lived assets did not have a material impact on the depreciation and amortization of these assets. The acquired property, plant, and equipment is stated at fair value, and depreciation of the acquired property, plant, and equipment is computed using the straight-line method over the estimated useful lives of each asset. Buildings are depreciated using useful lives of 15 to 30 years. Machinery and equipment is depreciated using useful lives of 2 to 20 years. Automobiles and trucks are depreciated using useful lives of 3 to 4 years. The acquired intangible assets represent approximately $33.7 million for the trademark/trade name, approximately $21.4 million for customer relationships, and approximately $12.9 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 2 to 15 years. These identified intangible assets are recorded net of approximately $9.7 million of accumulated amortization as of September 30, 2015.
For the three and nine month periods ended September 30, 2014, our revenues, depreciation and amortization, and pretax earnings included $61.0 million, $9.6 million, and $6.4 million, respectively, associated with the CSI Acquisition after the closing on August 4, 2014. In addition, CSI Acquisition-related costs of approximately $2.1 million and $3.0 million were incurred during the three and nine month periods ended September 30, 2014, respectively, consisting of external legal fees and due diligence costs. These costs have been recognized in general and administrative expenses in the consolidated statements of operations. Approximately $16.6 million of deferred financing costs related to the CSI Acquisition were incurred as of the acquisition date and included in Other Assets and is being amortized over the term of the related debt. An additional $9.3 million of interim financing costs related to the CSI Acquisition were incurred and reflected in other expense during the nine months ended September 30, 2014.
Pro Forma Financial Information
The pro forma information presented below has been prepared to give effect to the acquisition of CSI 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 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 transactions 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 period presented or the future results that we will achieve after the transaction.

NOTE C – LONG-TERM DEBT AND OTHER BORROWINGS
Our consolidated capital structure changed significantly during 2014 as a result of the CSI Acquisition. Because of the increased level of consolidated debt, it is increasingly important to consider TETRA's capital structure and CCLP's capital structure separately, as we have no cross default provisions, cross collateralization provisions, or cross guarantees with CCLP's debt, nor does CCLP with TETRA's debt.
Long-term debt consists of the following:

We and CCLP are in compliance with all covenants and conditions of our respective debt agreements as of September 30, 2015.
Our Senior Notes
On November 5, 2015, we entered into the 2015 Senior Note Purchase Agreement with GSO Tetra Holdings LP, an unrelated third party. Pursuant to the 2015 Senior Note Purchase Agreement, we agreed to issue and sell $125.0 million in aggregate principal amount of our Series 2015 Senior Notes. The Series 2015 Senior Notes will be sold in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended. Closing of the transaction is expected to occur on or before November 20, 2015. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. Thereafter, we are to apply any remaining portion of the proceeds, together with other funds (to the extent necessary), to (i) pay the purchase price for 2010 Senior Notes accepted for purchase pursuant to the Tender Offer, (ii) prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016 and (iii) pay fees and expenses associated with the transactions contemplated under the 2015 Senior Note Purchase Agreement.
The Series 2015 Senior Notes will bear interest at the fixed rate of 11.0% and mature on November 5, 2022. Interest on the Series 2015 Senior Notes will be due quarterly on March 15, June 15, September 15 and December 15 of each year, commencing on March 15, 2016. We may prepay the Series 2015 Senior Notes, in whole or in part (though not in an amount less than $1,000,000 in the aggregate in the case of a partial prepayment) at a prepayment price equal to (i) prior to the third anniversary of the date of the closing of the issuance and sale of the Series 2015 Senior Notes (the “Closing”), 100% of the principal amount so prepaid, plus accrued and unpaid interest and a “make-whole” prepayment amount, (ii) during the period commencing on the third anniversary of the Closing and ending on the day prior to the fourth anniversary of the Closing, 104% of the principal amount so prepaid, plus accrued and unpaid interest, (iii) during the period commencing on the fourth anniversary of the Closing and ending on the day prior to the fifth anniversary of the Closing, 102% of the principal amount so prepaid, plus accrued and unpaid interest, (iv) during the period commencing on the fifth anniversary of the Closing and ending on the day prior to the sixth anniversary of the Closing, 101% of the principal amount so prepaid, plus accrued and unpaid interest, and (v) from the sixth anniversary of Closing, 100% of the principal amount so prepaid, plus accrued and unpaid interest.
Pursuant to the 2015 Senior Note Purchase Agreement, the Series 2015 Senior Notes will be unsecured and guaranteed by certain of our material wholly owned U.S. subsidiaries. The 2015 Senior Note Purchase Agreement contains customary covenants that will 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 as set forth in the 2015 Senior Note Purchase Agreement. In addition, the 2015 Senior Note Purchase Agreement requires us to maintain certain consolidated financial ratios. The 2015 Senior Note Purchase Agreement contains customary default provisions, as well as the following cross-default provision. An event of default will occur if we or any of our restricted subsidiaries (i) fails to make any payment when due beyond any applicable grace period under any indebtedness of at least $20.0 million, (ii) defaults in the performance of or compliance with any term of any indebtedness in an aggregate outstanding principal amount of at least $20.0 million or of any mortgage, indenture or other agreement relating to such indebtedness or any other condition exists, and as a result of such default or condition such indebtedness is accelerated and declared due and payable before its stated maturity or before its regularly scheduled dates for payment, or (iii) we or any of our restricted subsidiaries become obligated to purchase or repay indebtedness before its regular maturity or before its regularly scheduled dates of payment in an aggregate outstanding principal amount of at least $20.0 million or one or more persons have the right to require us or any of our subsidiaries to purchase or repay such indebtedness. Upon the occurrence and during the continuation of an event of default under the 2015 Senior Note Purchase Agreement, the Series 2015 Senior Notes may become immediately due and payable, either automatically or by declaration of holders of more than 50% in principal amount of the Series 2015 Senior Notes at the time outstanding.
As discussed above, immediately after closing and funding of the Series 2015 Senior Notes, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness outstanding under our Credit Agreement. In December 2015, and not later than forty-five days following the settlement of the Series 2015 Senior Notes, we are to prepay in full all amounts owed in respect of the
14

outstanding Series 2006-A Senior Notes, due April 30, 2016, including an estimated $1.7 million "make-whole" prepayment premium in accordance with the Master Note Purchase Agreement.
On November 5, 2015, we announced the commencement of the Tender Offer to purchase for cash up to $25.0 million aggregate principal amount of the outstanding 2010 Senior Notes. The Tender Offer is scheduled to expire immediately after 11:59 p.m., Eastern Time, on December 4, 2015, unless extended by us in our sole discretion or if we terminate the Tender Offer earlier (the "Expiration Time"). The offered consideration for 2010 Senior Notes of either series to be purchased in the Tender Offer is an amount, payable in cash, equal to $100,000 per $100,000 principal amount of 2010 Senior Notes validly tendered by registered holders of 2010 Senior Notes prior to the Expiration Time, and accepted for purchase by us pursuant to the Tender Offer, plus accrued and unpaid interest on such 2010 Senior Notes up to, but not including, the date of payment for such Notes.
Our Senior Secured Notes
On March 18, 2015, we entered into a Note Purchase Agreement (the "Note Purchase Agreement") with Wells Fargo Energy Capital, Inc., in its capacity as noteholder representative for the noteholders (the "Noteholder Representative"), and Wells Fargo Energy Capital, Inc., in its capacity as the sole initial purchaser. The Note Purchase Agreement relates to our issuance and sale of $50.0 million aggregate principal amount of Senior Secured Notes due April 1, 2017 (the "Senior Secured Notes"). On April 30, 2015, we completed the issuance and sale of the Senior Secured Notes in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The proceeds from these Senior Secured Notes were used to provide a portion of the funds necessary to repay the $90.0 million principal amount of the Series 2008-B Senior Notes that matured on April 30, 2015. The Senior Secured Notes are secured by our accounts receivable (excluding CCLP accounts receivable) and our common units in CCLP, and the related Note Purchase Agreement includes financial covenants consistent with those applicable to our existing bank revolving credit facility.
On November 5, 2015, we entered into the Second Amendment (the “Second Amendment”) to the Note Purchase Agreement that, conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, (i) provides for the extension of the maturity date of the Senior Secured Notes from April 1, 2017 to April 1, 2019, (ii) amends certain definitions in the Note Purchase Agreement and (iii) requires us to pay an extension fee for the ratable account of the noteholders under the Note Purchase Agreement.
The principal portion of each of the Senior Secured Notes consists of tranches that bear interest at LIBOR, as defined in the Note Purchase Agreement, plus an applicable margin ("LIBOR Tranches") and tranches that bear interest at the Base Rate plus an applicable margin ("Base Rate Tranches"), as we may request in accordance with the Note Purchase Agreement. The initial Senior Secured Note consists of a LIBOR Tranche and the interest rate at closing and as of September 30, 2015 is 3.95% per annum. We may convert the LIBOR Tranche into a Base Rate Tranche in accordance with the Note Purchase Agreement. The Note Purchase Agreement contains customary covenants and default and cross default provisions consistent with the agreements governing our other TETRA indebtedness.
NOTE D – DECOMMISSIONING AND OTHER ASSET RETIREMENT OBLIGATIONS
The large majority of our asset retirement obligations consists of the remaining future well abandonment and decommissioning costs for offshore oil and gas properties and platforms owned by our Maritech subsidiary, including the decommissioning and debris removal costs associated with its remaining offshore platforms previously destroyed by hurricanes. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners. We also 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.
The values of our asset retirement obligations for non-Maritech properties were approximately $8.8 million and $8.4 million as of September 30, 2015 and December 31, 2014, respectively. We are required to take certain actions in connection with the retirement of these assets. We have reviewed our obligations in this regard in detail and estimated the cost of these actions. The original estimates are the fair values that have been recorded for retiring these long-lived assets. The associated asset retirement costs are capitalized as part of the carrying amount of these long-lived assets. The costs for non-oil and gas assets are depreciated on a straight-line basis over the life of the assets.
15

The changes in the values of our asset retirement obligations during the three and nine month periods ended September 30, 2015, are as follows:

| Three Months Ended September 30, 2015 |  | Nine Months Ended September 30, 2015
| (In Thousands)
Beginning balance for the period, as reported | $ | 59,408 |  |  | $ | 62,741 |
Activity in the period: |  |  |
Accretion of liability | 571 |  |  | 1,413 |
Retirement obligations incurred | — |  |  | — |
Revisions in estimated cash flows | 1,110 |  |  | 1,347 |
Settlement of retirement obligations | (1,113 | ) |  | (5,525 | )
Ending balance | $ | 59,976 |  |  | $ | 59,976 |

We review the adequacy of our asset retirement obligation liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed. For our Maritech segment, the timing and amounts of these cash flows are subject to changes in the energy industry environment and other factors and may result in additional liabilities and charges to cost of product sales to be recorded.
Asset retirement obligations are recorded in accordance with FASB ASC 410, which requires that the estimated fair value of a liability for asset retirement obligations be recorded 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. The cost estimates for our Maritech asset retirement obligations are considered reasonable estimates consistent with current market conditions, and we believe reflect the amount of work legally required to be performed in accordance with Bureau of Safety and Environmental Enforcement ("BSEE") standards, as revised from time to time.
NOTE E – 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. Our policy is to evaluate, prior to providing goods or services, each customer's financial condition and to determine the amount of open credit to be extended. We generally require appropriate additional collateral as security for credit amounts in excess of approved limits. Our customers consist primarily of major, well-established oil and gas producers and independent oil and gas companies. The risk of loss from the inability to collect trade receivables, including certain long-term contractual receivables of our Maritech Division, is heightened during prolonged periods of low oil and natural gas commodity prices.
We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. As a result of our variable rate bank credit facilities, including the variable rate credit facility of CCLP, we face market risk exposure related to changes in applicable interest rates. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures.

Derivative Contracts
Foreign Currency Derivative Contracts. As of September 30, 2015, 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 |  | $ | 2,869 |  |  | 1.13 |  | 10/16/2015
Forward purchase pounds sterling |  | $ | 9,035 |  |  | 1.53 |  | 10/16/2015
Forward sale Mexican peso |  | $ | 7,455 |  |  | 17.06 |  | 10/16/2015
Forward sale Saudi Arabia riyal |  | $ | 6,397 |  |  | 3.75 |  | 10/16/2015
Forward sale Mexican peso |  | $ | 3,936 |  |  | 17.06 |  | 10/16/2015

Under a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries, we and CCLP may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as economic hedges of the cash flow of our currency exchange risk exposure, they will not be formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period.
The fair value of foreign currency derivative instruments are based on quoted market values as reported to us by our counterparty (a level 2 fair value measurement). The fair values of our and CCLP's foreign currency derivative instruments as of September 30, 2015 and December 31, 2014, are as follows:

Foreign currency derivative instruments | Balance Sheet Location |  | Fair Value at September 30, 2015 |  | Fair Value at December 31, 2014
|  |  |  | (In Thousands)
Forward sale contracts |  | Current assets |  | $ | 3 |  |  | $ | — |
Forward purchase contracts |  | Current assets |  | $ | 41 |  |  | $ | — |
Forward sale contracts |  | Current liabilities |  | (77 | ) |  | (91 | )
Forward purchase contracts |  | Current liabilities |  | (135 | ) |  | (83 | )
Net liability |  |  |  | $ | (168 | ) |  | $ | (174 | )

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 nine month periods ended September 30, 2015, we recognized approximately $(0.2) million and $(0.5) million, respectively, of net losses in other income (expense) associated with our foreign currency derivative program. During the three and nine month periods ended September 30, 2014, we recognized approximately $(0.8) million and $(0.8) million, respectively, of net losses in other income (expense) associated with our foreign currency derivative program.

NOTE G – 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.
Environmental
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.
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. For those oil and gas properties Maritech previously operated, the buyers of the properties assumed the financial responsibilities associated with the properties' operations, including abandonment and decommissioning, and generally became the successor operator. Some buyers of these Maritech properties subsequently sold certain of these properties to other buyers who also assumed these financial responsibilities associated with the properties' operations, and these buyers also typically became the successor operator of the properties. To the extent that a buyer of these properties fails to perform the abandonment and decommissioning work required, the previous owner, including Maritech, may be required to perform the abandonment and decommissioning obligation. A significant portion of the decommissioning liabilities that were assumed by the buyers of the Maritech properties in 2011 remains unperformed and we believe the amounts of these remaining liabilities are significant. We monitor the financial condition of the buyers of these properties from Maritech, and if current oil and natural gas pricing levels continue, we expect that one or more of these buyers may be unable to perform the decommissioning work required on the properties acquired from Maritech.
During the nine months ended September 30, 2015, continued low oil and natural gas prices have resulted in reduced revenues and cash flows for all oil and gas producing companies, including those companies that bought Maritech properties in the past. Certain of these oil and gas producing companies that bought Maritech properties are currently experiencing severe financial difficulties. With regard to certain of these properties, Maritech has security in the form of bonds or cash escrows intended to secure the buyers' obligations to perform the decommissioning work. One company that bought, and subsequently sold, Maritech properties filed for Chapter 11 bankruptcy protection in August 2015. Maritech and its legal counsel monitor the status of these companies. As of September 30, 2015, we do not consider the likelihood of Maritech becoming liable for decommissioning liabilities on sold properties to be probable.
NOTE H – INDUSTRY SEGMENTS
We manage our operations through five reporting segments organized into four divisions: Fluids, Production Testing, Compression, and Offshore.
Our Fluids 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
19

a variety of markets outside the energy industry. The Fluids Division also provides domestic onshore oil and gas operators with comprehensive water management services.
Our Production Testing Division 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 and parts 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 as well as the sale of compressor package parts and components manufactured by third-party suppliers. The Compression Division's aftermarket services business provides compressor package reconfiguration and maintenance services. 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. As a result of the August 4, 2014 acquisition of CSI, we have significantly expanded the scope of our Compression Division.
Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea services such as well plugging and abandonment and workover services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturation diving services.
The Maritech segment is a limited oil and gas production operation. During 2011 and the first quarter of 2012, Maritech sold substantially all of its oil and gas producing property interests. Maritech’s operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells and production platforms. Maritech intends to acquire a portion of these services from the Offshore Division’s Offshore Services segment.
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.
Summarized financial information concerning the business segments is as follows:

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 filed with the SEC on March 2, 2015. This discussion includes forward-looking statements that involve certain risks and uncertainties.
Business Overview
The continued strong performance of our Fluids Division and the August 2014 acquisition by our Compression Division of Compressor Systems, Inc. ("CSI") resulted in growth in consolidated revenues and gross profit during the third quarter of 2015 compared to the prior year period. Increased offshore clear brine fluids ("CBF") and completion services activity, including from a customer project associated with a new completion fluids technology that was introduced during the first half of 2015, more than offset the decreased demand for onshore water management services and resulted in improved performance by the Fluids Division. Our Compression Division, through CSI Compressco LP ("CCLP"), also reflected growth in revenues and gross profit during the third quarter of 2015 compared to the prior year period, as the August 4, 2014 acquisition of CSI (the "CSI Acquisition") resulted in a full three months of activity during the current year quarterly period compared to approximately two months of the prior year quarter. The growth in these two divisions' results occurred despite the continuing overall industry market challenges as a result of lower oil and natural gas commodity prices compared to early 2014. Throughout the industry, drilling and completion activity continues to decrease, putting increased competitive pressure on several of our businesses. In addition to the decreased activity levels of the water management business of our Fluids Division, the current market environment has also negatively impacted our Production Testing and Offshore Services segments, as well as the low-horsepower production enhancement operations of our Compression Division. We continue to respond aggressively to the current environment with cost reduction actions, which have included reductions in headcount, deferral of salary increases, renegotiation of vendor contracts, and other cost restructuring measures. These steps have resulted in improved profitability for certain of our businesses, particularly for our Offshore Services segment, which reported increased profitability compared to the prior year period despite a significant decrease in revenues. As a result of the above factors, as well as from decreased Maritech excess decommissioning costs compared to the prior year period, our third quarter 2015 consolidated gross profit increased 103.0% compared to the corresponding prior year period, without an increase in revenues.
Given the lower demand for certain of our products and services in the current oil and natural gas services market environment, the expected level of future consolidated operating cash flows, which we have historically used to fund our growth and liquidity needs, has become more uncertain. While remaining committed to a long-term growth strategy, our near-term focus during this period of reduced demand is to preserve and enhance liquidity through strategic operating and financial measures. In addition to cost structure rationalization and working capital management, we have also focused on capital structure enhancements designed to strengthen our consolidated balance sheet. On November 5, 2015, we entered into a Note Purchase Agreement (the “2015 Senior Note Purchase Agreement”) with GSO Tetra Holdings LP, an unrelated third party. Pursuant to the 2015 Senior Note Purchase Agreement, we agreed to issue and sell $125.0 million in aggregate principal amount of our 11.0% Senior Notes due November 5, 2022 (the “Series 2015 Senior Notes”). Closing of the transaction is expected to occur on or before November 20, 2015. In addition, on November 5, 2015, we announced the commencement of a tender offer (the “Tender Offer”) to purchase for cash up to $25.0 million aggregate principal amount of the outstanding Series 2010-A Senior Notes and Series 2010-B Senior Notes (collectively, the “2010 Senior Notes”). Also on November 5, 2015, we entered into an amendment to the Note Purchase Agreement, conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, that provides for the extension of the maturity date of our $50.0 million Senior Secured Notes from April 2017 to April 2019. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. Thereafter, we are to apply any remaining portion of the proceeds, together with other funds (to the extent necessary) to (i) pay the purchase price for 2010 Senior Notes accepted for purchase pursuant to the Tender Offer (defined above), (ii) prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016 and (iii) pay fees and expenses associated with the transactions contemplated under the 2015 Senior Note Purchase Agreement. Following the completion of these transactions, we will have repaid and extended the maturity dates of a significant amount of TETRA's total long-term debt. In addition, we are considering certain additional financing transactions with a view of generating additional cash to reduce the amount of our outstanding borrowings under our credit agreement, repay or refinance additional amounts of our Senior Notes, and generate additional liquidity.

The August 2014 issuance of the CCLP 7.25% Senior Notes (the "CCLP Senior Notes") and borrowings under the CCLP Credit Agreement resulted in increased levels of our consolidated debt. However, we do not analyze or manage our capital structure on a consolidated basis, as there are no cross default provisions, cross collateralization provisions, or cross guarantees between CCLP's debt and TETRA's debt. Approximately $588.3 million of our consolidated debt balance is owed by CCLP, and is to be serviced by CCLP's existing cash balances and the future cash provided by CCLP's operations (less its capital expenditures) and is secured by the assets of CCLP.
The following table provides condensed consolidating balance sheet information reflecting our net assets and CCLP's net assets that service our and its respective capital structures.

TETRA’s debt is serviced by its existing cash balances and cash provided from operating activities (excluding CCLP), supplemented by the distributions we receive from CCLP and less cash capital expenditures (excluding CCLP). During the nine months ended September 30, 2015, consolidated cash provided from operating activities was $118.2 million, which included approximately $63.5 million generated by CCLP. Our cash provided from operating activities is reduced by the amount we spend for Maritech decommissioning liabilities, which was $5.2 million during the nine months ended September 30, 2015. During the first nine months of 2015, consolidated cash capital expenditures were $96.1 million, which included $76.0 million expended by CCLP. In addition, during the first nine months of 2015 we received $22.7 million from CCLP as our share of CCLP distributions.
Our consolidated operating cash flows during the nine months ended September 30, 2015, increased to $118.2 million, an increase of $66.3 million, or 127.6%, over the prior year period. Our consolidated operating cash flows not only reflect the acquisition of CSI, but also the impact of the fiscal management steps noted above and the growth of certain of our businesses. Consolidated capital expenditures were $96.1 million during the nine months ended September 30, 2015, and included approximately $76.0 million of capital expenditures by our Compression Division, compared to $84.1 million of consolidated capital expenditures during the corresponding prior year period. Compression Division capital expenditures primarily relate to its over 100-horsepower fleet, as the demand for lower horsepower compressor packages has decreased in the current market environment. Excluding the growth in Compression Division capital expenditures, which totaled $76.4 million during the nine months ended September 30, 2015, our capital expenditure levels reflect our efforts to defer or reduce capital expenditure projects in the current market environment. Key objectives associated with our separate 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 Senior Notes. CCLP plans to continue its 2015 capital expenditure program, while monitoring demand levels for its compression products and services in the current environment, by using its cash and available capacity under its revolving bank credit facility (the "CCLP Credit Agreement"). TETRA's future consolidated operating cash flows are also affected by the continuing challenges associated with extinguishing the remaining Maritech asset retirement obligations. The amount of recorded liability for these
24

remaining obligations is approximately $51.2 million as of September 30, 2015. Approximately $17.9 million of this amount is expected to be performed during the twelve month period ending September 30, 2016, with the timing of a portion of this work being discretionary.
Critical Accounting Policies
There have been no material changes or developments in the evaluation of the accounting estimates and the underlying assumptions or methodologies pertaining to our Critical Accounting Policies and Estimates disclosed in our Form 10-K for the year ended December 31, 2014, except as discussed below. In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. We periodically evaluate these estimates and judgments, including those related to potential impairments of long-lived assets (including goodwill), the collectability of accounts receivable, and the cost of future abandonment and decommissioning obligations. Our estimates are based on historical experience and on future expectations that we believe are reasonable. The fair values of large 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.
Goodwill Impairment Testing - Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired in purchase transactions. We perform a goodwill impairment test on an annual basis or whenever indicators of impairment are present. We perform the annual test of goodwill impairment following the fourth quarter of each year. Our annual assessment for goodwill impairment begins with a qualitative assessment of whether it is “more likely than not” that the fair values of our reporting units are less than their carrying values. If based on the events and circumstances we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform a two-step goodwill impairment test, where the first step compares the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value is in excess of the reporting unit carrying amount, no additional steps are necessary. However, if the carrying amount of the reporting unit exceeds its estimated fair value, a second step is performed, using a hypothetical purchase price methodology to allocate total fair value to the reporting unit's balance sheet, including its long-lived property, plant and equipment assets, and identified intangible assets. The resulting allocation of fair value to goodwill is then compared to the reporting units' goodwill balance, and any excess to fair value is then recorded in our statement of operations as an impairment. Our estimates of our reporting units' fair values, if required, are based on a combination of an income approach and a market approach. These estimates are imprecise and subject to our estimates of the future cash flows of our reporting units and our judgment as to how these estimated cash flows translate into our reporting units’ estimated fair value. These estimates and judgments are affected by numerous factors, including the general economic environment at the time of our assessment, which affects our overall market capitalization. If we overestimate the fair value of our reporting units, the balance of our goodwill assets may be overstated. Alternatively, if our estimated fair values are understated, an impairment might be recognized unnecessarily or in excess of the appropriate amount.
In our most recent annual goodwill impairment assessment as of December 31, 2014, based on our qualitative assessment, we determined that it was "more likely than not" that the fair values of one or more of our reporting units were less than their respective carrying values. As a result of the goodwill assessment analysis described above, as of December 31, 2014, we recorded an impairment of the entire $3.9 million of recorded goodwill for our Offshore Services reporting unit and a partial impairment of $60.4 million of the goodwill of our Production Testing reporting unit. As of September 30, 2015, our Fluids, Production Testing, and Compression reporting units reflect goodwill in the amounts of $6.6 million, $51.9 million, and $233.6 million, respectively. During the first nine months of 2015, global oil and natural gas commodity prices continued to be decreased compared to the prior year period. The decreased levels of commodity prices have had, and are expected to continue to have, a negative impact on industry drilling and capital expenditure activity, which affects the demand for products and services of each of our reporting units. As of September 30, 2015, our stock price had decreased compared to December 31, 2014, resulting in an overall reduction in our market capitalization. As part of the first step of our third quarter 2015 goodwill impairment testing, we updated our assessment of the future cash flows for each of our reporting units as of September 30, 2015, applying expected long-term growth rates, discount rates, and terminal values that we consider reasonable. Our Maritech and Offshore Services reporting units are excluded because they have no recorded goodwill. We calculated a present value of the respective cash flows for each of our other reporting units to arrive at an estimate of fair value under the income approach, and then used the market approach
25

to corroborate these values. Based on these updated assumptions, we determined that the fair value of our Fluids reporting unit was significantly in excess of its carrying value. Because the fair values of our Production Testing and Compression reporting units exceeded their respective carrying values by approximately 10% and 4% as of September 30, 2015, there is a reasonable possibility that the $51.9 million and $233.6 million, respectively, of goodwill for these reporting units may be impaired in a future period as a non-cash charge to earnings, and the amount of such impairments may be material. Specific uncertainties affecting the estimated fair value of our Production Testing and Compression reporting units include the impact of competition, prices of oil and natural gas, future overall activity levels in the regions in which we operate, the activity levels of our significant customers, and other factors affecting the rate of future growth of these reporting units. These factors will continue to be reviewed and assessed going forward. Negative developments with regard to these factors could have a further negative effect on the fair values of our Production Testing and Compression reporting units.

Consolidated revenues for the current quarter decreased compared to the prior year quarter, despite increased revenues for the Compression Division as a result of the August 4, 2014 acquisition of CSI, and the inclusion of CSI revenues for the complete current year period. The acquisition of CSI, which generated increased revenues of approximately $39.6 million for the current year quarter compared to the prior year quarter, greatly expands the operations of our Compression Division, allowing it to participate in the compression market at a broader level. In addition, the Fluids Division also reflected increased revenues, primarily due to increased offshore CBF sales and related services, and despite decreased water management services revenues. These increases in Compression and Fluids Division revenues were offset by decreased revenues in our Production Testing and Offshore Services segments. The decreased revenues in these segments were primarily due to the impact of decreased industry demand and activity levels in many of the domestic and international markets we serve, largely caused by decreased oil and natural gas pricing. See Divisional Comparisons section below for additional discussion.
Consolidated gross profit increased during the current year quarter compared to the prior year quarter primarily due to the impact of our Fluids Division's increased offshore activity. In addition, Compression Division gross profit increased as a result of reflecting the impact from the CSI Acquisition for the complete current year quarter. Despite decreased revenues for our Production Testing and Offshore Services businesses, the negative impact on gross profit from these businesses was minimized by cost reduction efforts. Notably, gross profit from our Offshore Services business increased, despite a significant decrease in revenues, largely as a result of cost
26

reductions implemented in response to decreased activity levels. Maritech gross profit also increased compared to the prior year quarter, due to decreased excess decommissioning costs during the current year quarter.
Consolidated general and administrative expenses increased during the current year quarter compared to the prior year quarter, primarily due to the increase in the Compression Division administrative costs following the CSI Acquisition. During the prior year quarter, Compression Division general and administrative costs also included approximately $2.1 million of transaction costs related to the CSI Acquisition. Corporate Overhead general and administrative costs also increased compared to the prior year quarter primarily due to increased incentive and equity compensation costs. The increase in the Compression Division and Corporate Overhead general and administrative expenses was partially offset by decreased administrative costs for our Fluids, Production Testing, and Offshore Divisions, primarily as a result of administrative cost reduction efforts by these segments. Decreases in general and administrative expenses for the Production Testing and Offshore Divisions were accomplished despite an aggregate of approximately $2.2 million of increased bad debt expense compared to the prior year period. Consolidated general and administrative expense increased as a percentage of consolidated revenues despite the administrative cost reductions implemented by each of the above divisions.
Consolidated interest expense increased in the current year quarter due to increased borrowings, primarily from the increased borrowings by the Compression Division, through CCLP, to finance the CSI Acquisition and to fund its capital expenditures. Consolidated interest expense levels going forward are expected to continue to be increased compared to prior periods primarily due to the increased interest rate applicable to the Series 2015 Senior Notes and additional borrowings to fund the Compression Division capital expenditures.
Consolidated other expense was $2.0 million during the three months ended September 30, 2015 compared to $12.6 million during the prior year period, primarily due to the interim financing costs that were incurred during the prior year period by the Compression Division in connection with the CSI Acquisition.
Our consolidated effective tax rate for the current year quarter includes the effect of changes in our expected valuation allowance at the end of 2015 related to our deferred tax assets, such as our U.S. net operating loss carryforward. At December 31, 2014, we increased our valuation allowance primarily on our U.S. deferred tax assets after considering all available positive and negative evidence related to the realizability of our deferred tax assets. Similarly, after considering updated evidence related to the deferred tax assets of one of our international operations, during the third quarter of 2015 we also increased our valuation allowance for this international deferred tax asset. 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 increase in Fluids Division revenues during the current year quarter compared to the prior year quarter was primarily due to approximately $7.2 million of increased product sales revenues, primarily due to increased CBF and associated products sales revenues in the U.S. Gulf of Mexico. A large increase in product sales revenues was related to a single customer well completion project associated with a new completion fluid technology that was
27

introduced earlier in 2015. These increased CBF product sales revenues were partially offset by decreased sales of other manufactured products compared to the prior year period. Service revenues decreased approximately $1.9 million, as increased activity in the U.S. Gulf of Mexico was more than offset by decreased onshore water management services activity. The increased offshore completion service revenue was also associated with the new fluid technology completion project discussed above. Revenues from onshore water management services were decreased from the prior year quarter due to the impact of lower oil and natural gas commodity prices.
Fluids Division gross profit during the current year quarter increased compared to the prior year quarter primarily due to increased profitability associated with the mix of CBF products and services, particularly for offshore completion fluids products and services and the new fluid technology completion project discussed above. These increases in Fluids Division gross profit more than offset the reduced profitability of onshore water management services activity during the current year quarter. Operating cost reduction efforts also contributed to the improved gross profit compared to the prior year quarter.
Fluids Division income before taxes increased compared to the prior year quarter primarily due to the increased gross profit discussed above. In addition, the Fluids Division reduced its administrative cost levels compared to the prior year quarter, particularly for its onshore water management services operations, in light of current activity levels. The Fluids Division continues to review opportunities to further reduce its administrative costs.

Production Testing Division revenues decreased during the current year quarter compared to the prior year quarter due to decreased overall market activity. Industry activity levels have decreased compared to the prior year period due to decreased oil and natural gas commodity pricing. The impact of increased competition for decreased industry activity negatively affected our pricing and activity levels, although the Division has successfully expanded its domestic customer base compared to the prior year quarter.
Production Testing Division gross profit decreased during the current year quarter compared to the prior year quarter due to the decreased industry activity and increased competition as discussed above. The Production Testing Division also reflected an approximately $0.6 million charge related to a Brazilian Value Added Tax audit. This decrease in gross profit occurred despite cost reduction efforts, which have included headcount reductions and other steps to adjust the Production Testing Division's cost structure in light of current market conditions.
The Production Testing Division reported a pretax loss compared to pretax earnings during the prior year quarter, primarily due to decreased revenues and gross profit. General and administrative expenses increased due to approximately $2.1 million of increased bad debt expense, which more than offset administrative cost reductions, primarily from reduced headcount and other employee related cost reductions. The Division continues to review additional opportunities to further reduce its operating and administrative cost levels in light of current market conditions.

Compression Division revenues increased significantly during the current year quarter compared to the prior year quarter due to the CSI Acquisition. Approximately $20.2 million of the $14.9 million increase in service revenues were generated by the compression services and aftermarket services revenues of CSI. This increase in CSI revenue is attributable to a full three month period of activity being included in the current year quarter compared to approximately two months of activity in the prior year quarter, due to the August 4, 2014 CSI Acquisition date. This increase in revenue was offset by decreased non-CSI service revenues of approximately $5.3 million, primarily due to decreased demand for low-horsepower production enhancement compression services as a result of lower oil and natural gas commodity prices. Revenues from sales of compressor packages and parts during the current year quarter increased $18.1 million compared to the prior year quarter, with $19.4 million of the increase related to sales of compressors and parts by CSI, which was partially offset by decreased sales of non-CSI compressors and parts.
Compression Division gross profit increased during the current year quarter compared to the prior year quarter, also primarily due to the impact of the CSI Acquisition, which generated approximately $5.2 million of increased gross profit during the current year quarter. This increase in gross profit was partially offset by the decreased activity level of our non-CSI operations as discussed above. CSI gross profit includes approximately $16.6 million of depreciation and amortization expense, which reflects the allocation of the CSI Acquisition purchase price. CCLP is continuing to capture additional synergies anticipated as part of the integration of CSI's operations. These efforts will continue going forward and are expected to result in additional cost efficiencies in future periods.
The Compression Division reflected pretax earnings during the current year quarter compared to a pretax loss during the prior year quarter primarily due to decreased other expense, which included $9.3 million of interim financing costs associated with the CSI Acquisition and $0.6 million of decreased amortization costs in the prior year quarter. Interest expense increased as a result of the CCLP Senior Notes and the increased borrowings by CCLP under the CCLP Credit Agreement being outstanding for the full three month period during the current year quarter. These borrowings were used to finance a portion of the August 4, 2014 purchase price of the CSI Acquisition. Increased interest expense levels compared to the prior periods are expected to continue going forward, due to increased borrowings associated with the funding of ongoing capital expenditures. General and administrative expense levels increased compared to the prior year period, also due to a full three month period of CSI administrative expenses. In addition, general and administrative costs increased due to increased corporate allocated costs. These increases in administrative costs were partially offset by decreased professional services costs, as the prior year quarter included approximately $2.1 million of CSI Acquisition transaction costs.

Revenues for the Offshore Services segment decreased during the current year quarter compared to the prior year quarter primarily due to decreased revenues from its heavy lift and diving services businesses. Decreased heavy lift and diving services activity levels in the U.S. Gulf of Mexico during the current quarter reflected an overall decrease in demand in this market, partly due to property acquisitions by key customers that have resulted in a postponement of certain well abandonment projects. Given the current decreased oil and natural gas commodity price environment, Offshore Services anticipates a continued decrease in demand for its services for the foreseeable future. Offshore Services revenues during the current year quarter were also negatively impacted by the reduction in work performed for our Maritech segment compared to the prior year quarter, with $0.4 million of such work being performed during the current year quarter compared to $6.3 million of revenues during the prior year quarter. Revenues for work performed for Maritech, which are eliminated in consolidation, are expected to continue to be lower in future periods.
Gross profit for the Offshore Services segment increased compared to the prior year period despite the impact of decreased activity levels for heavy lift and diving services as discussed above, as a result of cost reduction measures and process efficiencies that have been implemented, including reducing the size of the segment's vessel and equipment fleets. As a result of these cost reductions and process efficiencies, gross profit as a percentage of revenue increased compared to the prior year quarter. The Offshore Services segment continues to consider additional opportunities to optimize its operating cost structure.
Offshore Services segment income before taxes increased compared to the prior year quarter primarily due to the increased gross profit and due to decreased general and administrative expenses, primarily from reduced salary and employee related expenses, and despite increased bad debt expense. The Offshore Services segment continues to review its administrative cost structure for additional cost reductions and process efficiency actions in response to current market conditions.

As a result of the sale of almost all of its producing properties during 2011 and 2012, Maritech revenues were negligible and are expected to continue to be negligible going forward.
Maritech gross loss decreased during the current year quarter compared to the prior year quarter, due to $22.9 million of increased excess decommissioning costs charged to earnings during the prior year quarter. Maritech charged $1.1 million of excess decommissioning costs to expense during the current year quarter.
Maritech’s pretax loss during the current year quarter decreased compared to the prior year quarter primarily due to decreased gross loss as discussed above.

Corporate Overhead pretax loss increased during the current year quarter compared to the prior year quarter, primarily due to increased general and administrative expense. Corporate general and administrative expenses increased due to approximately $4.8 million of increased employee-related expenses, primarily for incentive and equity compensation expense, and $0.5 million of increased professional service fees. These increased administrative expenses were offset by increased costs allocated to other segments of approximately $0.7 million. Corporate other expenses decreased compared to the prior year quarter due to increased gains associated with foreign currency derivative instruments of approximately $0.8 million. Interest expense decreased due to decreased TETRA borrowings outstanding during the current year quarter, but is expected to increase going forward following the issuance of the Series 2015 Senior Notes.

Consolidated revenues for the current year period increased compared to the prior year period primarily due to increased revenues for the Compression Division as a result of the CSI Acquisition. The CSI Acquisition, which resulted in increased revenues of approximately $207.2 million for the current year period, greatly expanded the operations of our Compression Division, allowing it to participate in the compression market at a broader level. Fluids Division revenues increased, as decreased onshore water management services and manufactured product sales revenues were more than offset by increased offshore completion services and CBF product sales revenues. These increases in Compression and Fluids Division revenues were partly offset by decreased revenues in our Offshore and Production Testing Divisions, primarily due to the impact of decreased industry demand and activity levels in many of the domestic and international markets we serve, largely caused by decreased oil and natural gas pricing. 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 results of our Fluids and Compression Divisions. The Fluids Division increase in gross profit was primarily due to the increased revenues and the mix of CBF products and services, particularly for U.S. Gulf of Mexico completion fluids products and services and increased profitability from our manufactured products operations. Compression Division gross profit increased as a result of the increased operations following the CSI Acquisition. In addition, our Offshore Services Division reflected increased gross profit, despite decreased revenues, largely as a result of cost reductions and efficiencies implemented in response to decreased activity levels. Maritech gross profit also increased compared to the prior year period, due to decreased excess decommissioning costs during the current year period. These increases in gross profit were partially offset by the decreased profitability of our Production Testing Division compared to the prior year period, as a result of a significant decrease in revenues and activity levels.
Consolidated general and administrative expenses increased during the current year period compared to the prior year period primarily due to the increase in the Compression Division administrative costs following the CSI Acquisition. Compression Division administrative expenses increased despite approximately $3.4 million of CSI Acquisition transaction costs in the prior year period. In addition, Corporate Overhead administrative expenses also increased, primarily due to increased incentive and equity compensation. The increase in the Compression Division and Corporate Overhead general and administrative expenses was partially offset by decreased administrative costs for our Fluids, Production Testing, and Offshore Divisions, primarily as a result of cost reduction efforts by
32

these segments. Consolidated general and administrative expense decreased as a percentage of consolidated revenues due to cost reductions and the increased revenues resulting from the CSI Acquisition.
Consolidated interest expense increased due to increased borrowings, primarily from the increased borrowings by the Compression Division, through CCLP. Consolidated interest expense levels going forward are expected to increase compared to the prior year periods as a result of the Series 2015 Senior Notes, which were issued in November 2015, and from CCLP borrowings associated with CCLP capital expenditure activity.
Consolidated other expense was $3.9 million during the current year period compared to $11.1 million during the prior year period. Included in net other expense during the prior year period was a $5.7 million gain associated with the acquisition of the interest in TETRA Arabia that we did not previously own. This gain during the 2014 period was partially offset by a $2.9 million charge associated with the settlement of the pre-existing relationship with the other shareholder during the prior year period. Other expense during the prior year period also includes $9.3 million of interim financing costs that were expensed in connection with the CSI Acquisition. Other expense during the current year period includes increased Compression Division financing cost amortization as a result of the financing for the CSI Acquisition.
Our consolidated effective tax rate for the current year period includes the effect of changes in our expected valuation allowance at the end of 2015 related to our deferred tax assets, such as our U.S. net operating loss carryforward. At December 31, 2014, we increased our valuation allowance primarily on our U.S. deferred tax assets after considering all available positive and negative evidence related to the realizability of our deferred tax assets. Similarly, after considering updated evidence related to the deferred tax assets of one of our international operations, during the third quarter of 2015 we also increased our valuation allowance for this international deferred tax asset. 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.

Revenues for the Fluids Division increased during the current year period compared to the prior year period, as approximately $19.8 million of increased product sales revenues were largely offset by $13.8 million of decreased services revenues. Product sales revenues increased primarily from increased CBF and associated product sales revenues from U.S. Gulf of Mexico product and services, including second and third quarter 2015 well completion projects for a single customer using new completion fluid technology introduced earlier in 2015. In addition, Fluids Division revenues increased from market share gains for domestic offshore CBF and associated products. This increase in domestic offshore CBF and associated product sales revenues more than offset decreased international sales of CBF products and manufactured products. Fluids Division service revenues decreased due to reduced onshore water management services revenues, reflecting the decreased activity levels as a result of lower oil and natural gas prices compared to the prior year period. Partially offsetting these decreased
33

service revenues, offshore U.S. Gulf of Mexico completion services revenues increased due to the new offshore completion fluids technology customer projects discussed above.
Fluids Division gross profit during the current year period increased compared to the prior year period primarily due to improved margins due to the mix of CBF products and services, including the increased U.S. Gulf of Mexico CBF and completion services revenues and the new completion fluid technology customer projects discussed above. Manufactured products gross profit also increased, partially due to $2.6 million of insurance claim proceeds received and credited to earnings during the current year period. Cost reduction efforts also contributed to the improved gross profit during the current year period compared to the prior year period.
Fluids Division income before taxes increased compared to the prior year period primarily due to the increased gross profit discussed above. Decreased Fluids Division other income was more than offset by decreased Fluids Division general and administrative costs, due to administrative cost reductions, primarily associated with the decreased water management operations. Other income decreased due to a $2.7 million allocated portion of the remeasurement gain recorded in the prior year period from our January 2014 acquisition of the remaining interest in TETRA Arabia. In connection with this acquisition, we recorded a $5.7 million consolidated gain from the fair value measurement of our previous investment in TETRA Arabia. No such gain was recorded in the current year period, resulting in the decrease in other income.

Production Testing Division revenues decreased during the current year period compared to the prior year period, due to decreased overall market activity. Increased competition for decreased industry activity negatively affected pricing levels for services, although the Division has successfully expanded its domestic customer base compared to the prior year period.
Production Testing Division gross profit decreased during the current year period compared to the prior year period, due to the market conditions discussed above, and despite the impact of cost reduction efforts, which have included headcount reductions and other steps to adjust the Production Testing Division's cost structure in light of the current market conditions.
Production Testing Division reported a pretax loss compared to pretax earnings during the prior year period, primarily due to the decrease in gross profit discussed above. The impact of administrative cost reductions was partially offset by $2.9 million of increased bad debt expense. In addition, other income increased due to increased gains on sales of assets, partly offset by increased foreign currency losses.

Compression Division revenues increased significantly during the current year period compared to the prior year period due to the CSI Acquisition, which generated aggregate revenues of approximately $268.2 million during the current year period. Approximately $122.1 million of the $119.2 million increase in compression service revenues were generated by the compression services and aftermarket services revenues of CSI. The increase in CSI revenue is primarily attributable to a full nine months of activity in the current year period compared to approximately two months of activity in the prior year period, due to the August 4, 2014 acquisition date. This increase in service revenue was partially offset by decreased non-CSI service revenue of approximately $2.9 million, primarily due to decreased demand for low-horsepower production enhancement compression services as a result of lower oil and natural gas commodity prices. Revenues from sales of compressor packages and parts during the current year period increased $81.4 million compared to the prior year period, with $85.1 million of increase related to sales of compressors and parts by CSI, partially offset by decreased sales of non-CSI compressors and parts.
Compression Division gross profit increased during the current year period compared to the prior year period, also primarily due to the impact of the CSI Acquisition, which generated approximately $29.2 million of increased gross profit during the current year period. This increase in gross profit was partially offset by the decreased activity level of our non-CSI operations as discussed above. CSI gross profit includes approximately $48.9 million of depreciation and amortization expense, which reflects the impact from the allocation of the CSI Acquisition purchase price. CCLP is continuing to capture additional synergies anticipated as part of the integration of CSI's operations. These efforts will continue going forward and are expected to result in additional cost efficiencies in future periods.
The Compression Division reflected an increase in pretax earnings during the current year period compared to the prior year period primarily due to the increased gross profit discussed above. Compression Division administrative expense levels increased compared to the prior year period, primarily due to the impact of the CSI Acquisition and the resulting increased corporate allocated costs, partly mitigated by certain administrative cost decreases and integration efficiencies. Interest expense increased significantly as a result of the issuance of the CCLP Senior Notes and the increased borrowings by CCLP under the CCLP Credit Agreement to finance a portion of the purchase price of the CSI Acquisition. Increased interest expense levels compared to the periods prior to the CSI Acquisition are expected to continue going forward, due to the borrowings associated with CSI Acquisition as well as the funding of ongoing capital expenditures. Other expense decreased primarily due to $9.3 million of interim financing commitment fees associated with the CSI Acquisition incurred in the prior year period, partially offset by $0.8 million of increased amortization of deferred finance costs of the current year period.

Revenues for the Offshore Services segment decreased significantly during the current year period compared to the prior year period due to decreased revenues from its diving, heavy lift services, and well abandonment businesses. Decreased diving and well abandonment activity levels in the U.S. Gulf of Mexico reflected an overall decrease in demand in this market, partly due to property acquisitions by key customers that have resulted in a postponement of certain well abandonment projects. Given the current decreased oil and natural gas commodity price environment, the Offshore Services segment anticipates a continued decrease in demand for its services compared to the prior year period for the foreseeable future. Offshore Services revenues during the current year period were also negatively affected by the reduction in work performed for our Maritech segment compared to the prior year period, with $3.6 million of such work being performed during the current year period compared to $13.1 million of revenues during the prior year period. Revenues for work performed for Maritech, which are eliminated in consolidation, are expected to continue to be lower in future periods.
Gross profit for the Offshore Services segment increased compared to the prior year period despite the impact of decreased activity levels for diving, well abandonment, and heavy lift services as discussed above. Cost reduction measures and process efficiencies that were implemented during the current and prior year period, including reducing the size of the segment's vessel and equipment fleets, resulted in increased gross profit. The Offshore Services segment continues to consider additional opportunities to optimize its operating cost structure.
Offshore Services segment loss before taxes decreased compared to the prior year period due to the increased gross profit discussed above and due to decreased general and administrative expenses. The Offshore Services segment continues to review its administrative cost structure, and made additional headcount reductions and process efficiency actions during the current year period.

As a result of the sale of almost all of its producing properties during 2011 and 2012, Maritech revenues were negligible and are expected to continue to be negligible going forward.
Maritech recorded a decreased gross loss during the current year period compared to the prior year period due to $41.9 million of excess decommissioning costs charged to earnings during the prior year period. Maritech recorded $0.8 million of excess decommissioning costs to expense during the current year period.
Maritech’s pretax loss during the current year period decreased compared to the prior year period primarily due to the decreased gross loss discussed above.

Corporate Overhead pretax loss increased during the current year period compared to the prior year period, primarily due to increased general and administrative expense. Corporate general and administrative costs increased primarily due to $7.5 million of increased employee related expenses, primarily from increased incentive and equity compensation. This increase was partially offset by approximately $2.9 million of increased costs allocated to other segments and $0.9 million of decreased professional fees. Corporate other expenses decreased compared to the prior year period due to increased gains associated with foreign currency derivative instruments. Interest expense decreased due to decreased TETRA borrowings outstanding during the current period, however, is expected to increase going forward following the November 2015 issuance of the Series 2015 Senior Notes.
Liquidity and Capital Resources
On November 5, 2015, we entered into the 2015 Senior Note Purchase Agreement with GSO Tetra Holdings LP. Pursuant to the 2015 Senior Note Purchase Agreement, we agreed to issue and sell $125.0 million in aggregate principal amount of the Series 2015 Senior Notes. Closing of the transaction is expected to occur on or before November 20, 2015. In addition, on November 5, 2015 we announced the commencement of the Tender Offer to purchase for cash up to $25.0 million aggregate principal amount of the outstanding Series 2010-A Senior Notes and Series 2010-B Senior Notes. The total outstanding balance of the Series 2010-A Senior Notes and the
37

Series 2010-B Senior Notes is $65.0 million and $25.0 million, respectively. Also on November 5, 2015, and conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, we extended the maturity date of our $50.0 million Senior Secured Notes from April 2017 to April 2019. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. Thereafter, we are to apply any remaining portion of the proceeds, together with other funds (to the extent necessary) to (i) pay the purchase price for 2010 Senior Notes accepted for purchase pursuant to the Tender Offer, (ii) prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016 and (iii) pay fees and expenses associated with the transactions contemplated under the 2015 Senior Note Purchase Agreement. Following the completion of these transactions, we will have repaid and extended the maturity dates of a significant portion of TETRA's total long-term debt without significantly increasing the amount of TETRA's net borrowings. In addition, we are considering certain additional financing transactions with a view of generating additional cash to reduce the amount of our outstanding borrowings under our Credit Agreement, repay or refinance additional amounts of our Senior Notes, and generate additional liquidity.
Despite a challenging market environment for a number of our businesses, our consolidated cash flows from operating activities increased during the first nine months of 2015 compared to the corresponding prior year period. This increase was due to a number of factors, including the CSI Acquisition, the impact of cost reduction efforts, and from a reduction in Maritech abandonment and decommissioning activities compared to the corresponding prior year period. Approximately $63.5 million of our consolidated operating cash flows during the nine months ended September 30, 2015 were generated by CCLP, and we received approximately $22.7 million of distributions from CCLP during the nine months ended September 30, 2015 compared to $17.6 million during the corresponding prior year period. Excluding the cash flows from operating activities of CCLP, our cash flows from operating activities, together with the borrowings available under our Credit Agreement, and our share of distributions from CCLP are expected to be adequate to fund our capital expenditures and debt service requirements through September 30, 2016. A portion of the increased operating cash flows of CCLP following the CSI Acquisition are used by CCLP to pay the debt service requirements of the CCLP Senior Notes and CCLP Credit Agreement. The anticipated levels of distributable cash flows of CCLP, along with the impact of the incentive distribution rights owned by CSI Compressco GP Inc., our wholly owned subsidiary, are expected to continue to result in an increase in the quarterly distributions we receive from CCLP going forward compared to the prior year period. Our ability to meet our financial obligations and fund future growth is dependent on future levels of consolidated operating cash flows and the availability of capital resources in uncertain operating and financial markets. Our consolidated sources and uses of cash during the nine months ended September 30, 2015 are as follows:

| Nine Months Ended September 30, 2015
| (In Thousands)
Operating activities | $ | 118,227 |
Investing activities | (94,947 | )
Financing activities | (44,570 | )

Our consolidated capital structure changed significantly during 2014 as a result of the CSI Acquisition. Because of the increased level of consolidated debt, it is increasingly important to consider TETRA's capital structure and CCLP's capital structure separately, as we have no cross default provisions, cross collateralization provisions, or cross guarantees with CCLP's debt, nor does CCLP with TETRA's debt. (See Financing Activities section below for a complete discussion of the terms of TETRA's and CCLP's respective debt arrangements.) Our consolidated debt outstanding has a carrying value of approximately $919.5 million as of September 30, 2015. However, approximately $588.3 million of this consolidated debt balance is owed by CCLP and is serviced from the existing cash balances and cash flows of CCLP and secured by its assets. Through our 44% ownership interest in CCLP and ownership of incentive distribution rights, we receive our share of the distributable cash flows of CCLP through its quarterly distributions. Approximately $18.3 million of the $25.5 million of the cash balance reflected on our consolidated balance sheet is owned by CCLP and is not accessible by us. As of September 30, 2015, CCLP had availability of approximately $156.2 million under the CCLP Credit Agreement, and we had availability of approximately $149.9 million under our Credit Agreement.
Beginning in 2014, and continuing into late-2015, significant decreases in oil and natural gas commodity
38

prices have lowered the capital expenditure and operating plans of many of our customers, creating additional uncertainty regarding the expected demand for many of our products and services and the resulting cash flows from operating activities for the foreseeable future. In addition, the availability of new borrowings in the current capital markets is more limited and costly. Accordingly, we continue to implement strategic cost reduction measures designed to lower our cost structure in the current environment, and have taken other steps to improve our operating cash flows. In connection with the issuance of $125.0 million of Series 2015 Senior Notes and conditioned upon the repayment of our 2006-A Senior Notes, we will have extended the maturity dates of a significant amount of TETRA long-term debt. We believe the steps taken have enhanced our capital structure and operating cash flows and will continue to enhance our operating cash flows in the future. As a result, we believe that despite the current industry environment and activity levels, we will have adequate liquidity to fund our operations and debt obligations and maintain compliance with debt covenants through September 30, 2016. However, we cannot predict how an extended period of low commodity prices will affect our operations and liquidity levels.
Operating Activities
Cash flows generated by operating activities totaled $118.2 million during the first nine months of 2015 compared to $51.9 million during the corresponding prior year period, an increase of $66.3 million. This increase in operating cash flows was due to the increased cash impact of earnings compared to the prior year period, including the cash impact of the acquired CSI operations. In addition, operating cash flows also increased due to the decrease in the amount spent on Maritech decommissioning activity, as approximately $5.2 million of decommissioning activity was performed during the nine months ended September 30, 2015 compared to $40.3 million during the corresponding prior year period.
Demand for a large portion of our products and services is driven by oil and gas industry activity, which is affected by oil and natural gas commodity pricing. Oil and natural gas prices have been volatile in the past and are expected to continue to be volatile in the future. In addition, as a result of the continued decrease in worldwide oil and natural gas commodity prices compared to early 2014, drilling activity related to oil and natural gas wells has decreased. In particular, certain of our Production Testing Division, Compression Division, and Fluids Division operations are vulnerable to the impact of a sustained low natural gas price environment. In addition, decreased worldwide crude oil prices have affected, and are likely to continue to affect, overall industry drilling activity in certain of the other regions in which we operate. 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 the first nine months of 2015, we have continued to take steps to reduce operating and administrative headcount for each of our segments. These steps are designed to further streamline our operations and downsize our organization, particularly in response to continuing market challenges for certain of our businesses. Together with the specific cost reduction steps taken during prior periods, these cost reduction efforts have resulted in increased operating cash flows and improved profitability. We continue to review our overall operating and administrative cost structure in order to identify additional opportunities to reduce costs.
As part of its integration of CSI, CCLP is continuing to capture additional strategic and operational synergies identified in connection with the CSI Acquisition. Such synergies include improved utilization of idle equipment, field level cost reductions, and reductions in combined general and administrative expenses. These efforts are designed to improve the efficiency of the combined operations, and are expected to increase operating cash flows.
As of September 30, 2015, Maritech’s decommissioning liabilities associated with its remaining offshore oil and gas production wells, platforms, and facilities totaled approximately $51.2 million. Approximately $17.9 million of this amount is expected to be performed during the twelve month period ended September 30, 2016, with the timing of a portion of this work being discretionary. Until the remaining decommissioning liabilities are extinguished, our future operating cash flows will continue to be affected by Maritech’s decommissioning expenditures as they are incurred. Included in Maritech’s decommissioning liabilities is the remaining abandonment, decommissioning, and debris removal associated with offshore platforms that were previously destroyed by a hurricane as well as certain remediation work required on wells that were previously plugged. Due to the unique nature of the remaining work to be performed associated with these properties, actual costs could greatly exceed these estimates and could therefore result in significant charges to earnings in future periods.
39

Asset retirement obligations are recorded in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 410, whereby the estimated fair value of a liability for asset retirement obligations is recorded 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. The cost estimates for Maritech asset retirement obligations are considered reasonable estimates consistent with market conditions at the time they are made, and we believe reflect the amount of work required to be performed in accordance with Bureau of Safety and Environmental Enforcement ("BSEE") standards, as revised from time to time.
The amount of work performed or estimated to be performed on a Maritech property asset retirement obligation often exceeds amounts previously estimated for numerous reasons including physical subsea, geological, or downhole conditions, that are different from those anticipated at the time of estimation due to the age of the property and the quality of information available about the particular property conditions. Maritech’s remaining oil and gas properties and production platforms were drilled and constructed by other operators many years ago and frequently there is not a great deal of detailed documentation on which to base the estimated asset retirement obligation for these properties. Appropriate underwater surveys are typically performed to determine the condition of such properties as part of our due diligence in estimating the costs, but not all conditions have been able to be determined prior to the commencement of the actual work.
Certain remaining Maritech properties were damaged by hurricanes in the past, leaving their production platforms leaning or toppled on the seabed and production tubing from the wells (which may be under high pressure) bent underwater. While the basic procedures involved in the plugging and abandonment of wells and decommissioning of platforms and pipelines and removal of debris is generally similar for these properties, the cost of performing work at these damaged locations is particularly difficult to estimate due to the unique conditions encountered, including the uncertainty regarding the extent of physical damage to many of the structures. Maritech has one remaining toppled platform as part of its asset retirement obligation as of September 30, 2015. During the performance of asset retirement activities, unforeseen weather or other conditions may extend the duration and increase the cost of the projects, which are normally not done on a fixed price basis, thereby resulting in costs in excess of the original estimate.
In addition, Maritech has encountered situations where previously plugged and abandoned wells on its properties have later exhibited a build-up of pressure that is evidenced by gas bubbles coming from the plugged well head. We refer to this situation as “wells under pressure” and this can either be discovered by us when we perform additional work at the property or by notification from a third party. Wells under pressure require Maritech to return to the site to perform additional plug and abandonment procedures that were not originally anticipated or included in the estimate of the asset retirement obligation for such property. Remediation work at previously abandoned well sites is particularly costly due to the lack of a platform from which to base these activities. Maritech is the last operator of record for its plugged wells and bears the risk of additional future work required as a result of wells becoming under pressure in the future.
For oil and gas properties previously operated by Maritech, the purchaser of the properties generally became the successor operator and assumed the financial responsibilities associated with the properties’ operations and abandonment and decommissioning. However, to the extent that purchasers of these oil and gas properties fail to perform the abandonment and decommissioning work required and there is insufficient bonding or other security, the previous owners and operators of the properties, including Maritech, may be required to assume responsibility for the abandonment and decommissioning obligations.
Investing Activities
During the first nine months of 2015, the total amount of our net cash utilized on investing activities was $94.9 million. Total cash capital expenditures during the first nine months of 2015 were $96.1 million. Approximately $9.7 million of our capital expenditures during the first nine months of 2015 was spent by our Fluids Division, the majority of which related to chemical plant improvements and the purchase of new equipment to support its water management services business. Our Production Testing Division spent approximately $6.5 million on capital expenditures, primarily to add to its international production testing equipment fleet. Our Compression Division spent approximately $76.0 million, primarily for the expansion of its compressor and equipment fleet for its CSI subsidiary. Our Offshore Services segment spent approximately $3.5 million on its various heavy lift barges and dive support vessels, primarily for required drydock expenditures.
40

Generally, a significant 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 in an effort to conserve capital or otherwise address expected future market conditions. During the current period of reduced oil and natural gas prices, we are reviewing all capital expenditure plans carefully in an effort to conserve cash and fund our liquidity needs. The deferral of capital projects could affect our ability to compete in the future. Excluding the capital expenditures of CCLP, we expect to spend approximately $25 to $35 million during 2015, and $19.8 million of this amount was expended during the first nine months of the year. CCLP expects to spend approximately $100 million during 2015, $76.0 million of which was expended during the first nine months of the year. The level of capital expenditures during the remainder of 2015 is subject to the impact of possible acquisitions and future market conditions.
Financing Activities
To fund our capital and working capital requirements, we may supplement our existing cash balances and cash flow from operating activities from short-term borrowings, long-term borrowings, operating leases, equity issuances, and other sources of capital.
TETRA Long-Term Debt
Bank Credit Facilities. As of November 9, 2015, TETRA (excluding CCLP) had an outstanding balance on its revolving credit facility (the "Credit Agreement") of approximately $75.0 million, and had $9.4 million in letters of credit and guarantees against the revolving credit facility, leaving a net availability of $140.6 million. These amounts do not reflect the CCLP Credit Agreement, which is separate and distinct from TETRA's Credit Agreement.
Under the Credit Agreement, which matures on September 30, 2019, the revolving credit facility is unsecured and guaranteed by our material U.S. subsidiaries (excluding CCLP and its subsidiaries). Borrowings generally bear interest at the British Bankers Association LIBOR rate plus 1.50% to 2.75%, depending on one of our financial ratios. We pay a commitment fee ranging from 0.225% to 0.500% on unused portions of the facility. The Credit Agreement contains customary covenants and other restrictions, including certain financial ratio covenants based on TETRA's levels of debt and interest cost compared to a defined measure of TETRA's operating cash flows over a twelve month period. These financial ratios include a minimum interest charge coverage ratio (ratio of a defined measure of earnings to interest) of 3.0 and an initial maximum leverage ratio (ratio of debt and letters of credit outstanding to a defined measure of earnings) of 3.5. The maximum leverage ratio decreased to 3.25 as of September 30, 2015, and it will decrease further to 3.0 as of March 31, 2016. Consolidated net earnings under the credit facility is defined as the aggregate of our net income (or loss) and our consolidated restricted subsidiaries (which does not include CCLP), including cash dividends and distributions (not the return of capital) received from persons other than consolidated restricted subsidiaries (including CCLP) and after allowances for taxes for such period determined on a consolidated basis in accordance with GAAP, excluding certain items more specifically described therein. At September 30, 2015, our leverage ratio was 2.02 to 1, compared to 2.38 to 1 at June 30, 2015 and 2.94 to 1 at December 31, 2014.
The Credit Agreement includes cross-default provisions relating to any other indebtedness (not including 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. We are in compliance with all covenants and conditions of TETRA's Credit Agreement as of September 30, 2015. Our continuing ability to comply with these financial covenants depends largely upon our ability to generate adequate cash flow. Historically, our financial performance has been more than adequate to meet these covenants. Due to the decreased demand for certain of our products and services by our customers in response to decreased oil and natural gas prices, we have taken strategic cost reduction efforts, including headcount reductions and other efforts, to reduce costs and generate cash to mitigate the reduced demand for our products and services. In addition, certain of our businesses have seen increased activity and profitability levels, despite current oil and natural gas prices. Based on our projections for each of the four quarterly periods subsequent to September 30, 2015, and including the impact of these cost reduction efforts and increased activity levels on future estimated operating cash flows, we anticipate that we will have sufficient liquidity to maintain compliance with the financial covenants under the Credit Agreement through September 30, 2016. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. In December 2015, and not later than forty-five days following the settlement of the Series 2015 Senior Notes, we are to apply any remaining portion of the proceeds,
41

together with borrowings under our Credit Agreement (to the extent necessary) to prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016. We are also reviewing the sale of selected assets and additional financing alternatives as a source of proceeds to further repay or refinance a portion of TETRA's outstanding borrowings. There can be no assurances that these cost reduction or cash generation efforts will be successful, or that market conditions and our operating performance will not further decrease compared to our projections.
Senior Notes. In April 2006, we issued $90.0 million in aggregate principal amount of Series 2006-A Senior Notes pursuant to our existing Master Note Purchase Agreement dated September 2004, as supplemented as of April 18, 2006. The Series 2006-A Senior Notes bear interest at a fixed rate of 5.90% and mature on April 30, 2016. Interest on the Series 2006-A Senior Notes is due semiannually on April 30 and October 30 of each year. As discussed above, immediately after closing and funding of the Series 2015 Senior Notes, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness outstanding under our Credit Agreement. In December 2015, and not later than forty-five days following the settlement of the Series 2015 Senior Notes, we are to prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016, including an estimated $1.7 million "make-whole" prepayment premium in accordance with the Master Note Purchase Agreement.
In April 2008, we issued $90.0 million in aggregate principal amount of Series 2008-B Senior Notes pursuant to a Note Purchase Agreement dated April 30, 2008. The Series 2008-B Senior Notes bore interest at a fixed rate of 6.56% and matured and were repaid on April 30, 2015.
In December 2010, we issued $65.0 million in aggregate principal amount of Series 2010-A Senior Notes and $25.0 million in aggregate principal amount of Series 2010-B Senior Notes pursuant to a Note Purchase Agreement dated September 30, 2010. The Series 2010-A Senior Notes bear interest at a fixed rate of 5.09% and mature on December 15, 2017. The Series 2010-B Senior Notes bear interest at a fixed rate of 5.67% and mature on December 15, 2020. Interest on the Series 2010 Senior Notes is due semiannually on June 15 and December 15 of each year.
On November 5, 2015, we announced the commencement of the Tender Offer to purchase for cash up to $25.0 million aggregate principal amount of the outstanding 2010 Senior Notes. The Tender Offer is scheduled to expire immediately after 11:59 p.m., Eastern Time, on December 4, 2015, unless extended by us in our sole discretion or if we terminate the Tender Offer earlier (the "Expiration Time"). The offered consideration for 2010 Senior Notes of either series to be purchased in the Tender Offer is an amount, payable in cash, equal to $100,000 per $100,000 principal amount of 2010 Senior Notes validly tendered by registered holders of 2010 Senior Notes prior to the Expiration Time, and accepted for purchase by us pursuant to the Tender Offer, plus accrued and unpaid interest on such 2010 Senior Notes up to, but not including, the date of payment for such Notes.
In April 2013, we issued $35.0 million in aggregate principal amount of Series 2013 Senior Notes pursuant to a Note Purchase Agreement dated April 29, 2013. The Series 2013 Senior Notes bear interest at a fixed rate of 4.0% and mature on April 29, 2020. Interest on the Series 2013 Senior Notes is due semiannually on April 29 and October 29 of each year.
We may prepay the Senior Notes, in whole or in part, at any time at a price equal to 100% of the principal amount outstanding, plus accrued and unpaid interest and a “make-whole” prepayment premium. The Senior Notes are unsecured and are guaranteed by substantially all of our wholly owned U.S. subsidiaries. The Note Purchase Agreements and the Master Note Purchase Agreement, as supplemented, contain customary covenants and restrictions and require us to maintain certain financial ratios, including a minimum level of net worth and a ratio between TETRA's long-term debt balance and a defined measure of operating cash flow over a twelve month period. These financial ratios include a maximum leverage ratio (ratio of debt and letters of credit outstanding to a defined measure of earnings) of 3.5. Consolidated net earnings under the Note Purchase Agreements and Master Note Purchase Agreement is defined as the aggregate of our net income (or loss) and our consolidated restricted subsidiaries, including cash dividends and distributions (not the return of capital) received from persons other than consolidated restricted subsidiaries (such as CCLP) and after allowances for taxes for such period determined on a consolidated basis in accordance with GAAP, excluding certain items more specifically described therein. Under these note purchase agreements, the financial ratio requirements include a minimum interest coverage ratio of 2.5 and a maximum leverage ratio of 3.5. At September 30, 2015, our leverage ratio was 2.02 to 1.
42

The Note Purchase Agreements and the Master Note Purchase Agreement also contain customary default provisions as well as a cross-default provision relating to any other of TETRA indebtedness of $20.0 million or more. We are in compliance with all covenants and conditions of the Note Purchase Agreements and the Master Note Purchase Agreement as of September 30, 2015. Our continuing ability to comply with these financial covenants depends largely upon our ability to generate adequate cash flow. Historically, our financial performance has been more than adequate to meet these covenants, and we expect this trend to continue. Based on our projections for each of the four quarterly periods subsequent to September 30, 2015, and including the impact of these cost reduction efforts and increased activity levels on estimated future operating cash flows, we anticipate that we will have sufficient liquidity to be in compliance with the financial covenants under the Note Purchase Agreements and the Master Note Purchase Agreement through September 30, 2016.
On November 5, 2015, we entered into the 2015 Senior Note Purchase Agreement with GSO Tetra Holdings LP. Pursuant to the 2015 Senior Note Purchase Agreement, we agreed to issue and sell $125 million in aggregate principal amount of our Series 2015 Senior Notes. The Series 2015 Senior Notes will be sold in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). Closing of the transaction is expected to occur on or before November 20, 2015. Immediately after closing and funding, we are required to apply a portion of the proceeds from the sale of the Series 2015 Senior Notes to repay all of the indebtedness for borrowed money outstanding under our Credit Agreement. Thereafter, we are to apply any remaining portion of the proceeds, together with other funds (to the extent necessary), to (i) pay the purchase price for 2010 Senior Notes accepted for purchase pursuant to the Tender Offer, (ii) prepay in full all amounts owed in respect of the outstanding Series 2006-A Senior Notes, due April 30, 2016 and (iii) pay fees and expenses associated with the transactions contemplated under the 2015 Senior Note Purchase Agreement.
The Series 2015 Senior Notes will bear interest at the fixed rate of 11.0% and mature on November 5, 2022. Interest on the Series 2015 Senior Notes will be due quarterly on March 15, June 15, September 15 and December 15 of each year, commencing on March 15, 2016. We may prepay the Series 2015 Senior Notes, in whole or in part (though not in an amount less than $1,000,000 in the aggregate in the case of a partial prepayment) at a prepayment price equal to (i) prior to the third anniversary of the date of the closing of the issuance and sale of the Series 2015 Senior Notes (the “Closing”), 100% of the principal amount so prepaid, plus accrued and unpaid interest and a “make-whole” prepayment amount, (ii) during the period commencing on the third anniversary of the Closing and ending on the day prior to the fourth anniversary of the Closing, 104% of the principal amount so prepaid, plus accrued and unpaid interest, (iii) during the period commencing on the fourth anniversary of the Closing and ending on the day prior to the fifth anniversary of the Closing, 102% of the principal amount so prepaid, plus accrued and unpaid interest, (iv) during the period commencing on the fifth anniversary of the Closing and ending on the day prior to the sixth anniversary of the Closing, 101% of the principal amount so prepaid, plus accrued and unpaid interest, and (v) from the sixth anniversary of Closing, 100% of the principal amount so prepaid, plus accrued and unpaid interest.
Pursuant to the 2015 Senior Note Purchase Agreement, the Series 2015 Senior Notes will be unsecured and guaranteed by certain of our material wholly owned U.S. subsidiaries. The 2015 Senior Note Purchase Agreement contains customary covenants that will 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 as set forth in the 2015 Senior Note Purchase Agreement. In addition, the 2015 Senior Note Purchase Agreement requires us to maintain certain consolidated financial ratios. The 2015 Senior Note Purchase Agreement contains customary default provisions, as well as the following cross-default provision. An event of default will occur if we or any our restricted subsidiaries (i) fails to make any payment when due beyond any applicable grace period under any indebtedness of at least $20.0 million, (ii) defaults in the performance of or compliance with any term of any indebtedness in an aggregate outstanding principal amount of at least $20.0 million or of any mortgage, indenture or other agreement relating to such indebtedness or any other condition exists, and as a result of such default or condition such indebtedness is accelerated and declared due and payable before its stated maturity or before its regularly scheduled dates for payment, or (iii) the we or any of our restricted subsidiaries becomes obligated to purchase or repay indebtedness before its regular maturity or before its regularly scheduled dates of payment in an aggregate outstanding principal amount of at least $20.0 million or one or more persons have the right to require us or any of our subsidiaries to purchase or repay such indebtedness. Upon the occurrence and during the continuation of an event of default under the 2015 Senior Note Purchase Agreement, the Series 2015 Senior Notes may become immediately due and payable, either automatically or by declaration of holders of more than 50% in principal amount of the Series 2015 Senior Notes at the time outstanding.
43

Senior Secured Notes. On March 18, 2015, we entered into a Note Purchase Agreement (the "Note Purchase Agreement") with Wells Fargo Energy Capital, Inc., in its capacity as noteholder representative for the noteholders (the "Noteholder Representative"), and Wells Fargo Energy Capital, Inc., in its capacity as the sole initial purchaser. The Note Purchase Agreement relates to the issuance and sale of $50.0 million aggregate principal amount of Senior Secured Notes due April 1, 2017 (the "Senior Secured Notes"). On April 30, 2015, we completed the issuance and sale of the Senior Secured Notes in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The proceeds from these Senior Secured Notes were used to provide a portion of the funds necessary to repay the $90.0 million principal amount repayment of the Series 2008-B Senior Notes that matured on April 30, 2015. The Senior Secured Notes are secured by our accounts receivable (excluding CCLP accounts receivable) and our limited partner interest in CCLP.
On November 5, 2015, we entered into the Second Amendment (the “Second Amendment”) to the Note Purchase Agreement that, conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, (i) provides for the extension of the maturity date of the Senior Secured Notes from April 1, 2017 to April 1, 2019, (ii) amends certain definitions in the Note Purchase Agreement and (iii) requires us to pay an extension fee for the ratable account of the noteholders under the Note Purchase Agreement.
The Note Purchase Agreement, as amended, contains customary covenants and restrictions and requires us to comply with certain financial covenants, including a minimum interest coverage ratio of 2.5. These financial ratios also include a maximum leverage ratio (ratio of debt and letters of credit outstanding to a defined measure of earnings (as defined in the Note Purchase Agreement)) of 3.5. At September 30, 2015, our leverage ratio was 2.02 to 1.
The principal portion of each of the Senior Secured Notes consists of tranches that bear interest at LIBOR, as defined in the Note Purchase Agreement, as amended, plus an applicable margin ("LIBOR Tranches") and tranches that bear interest at the Base Rate plus an applicable margin ("Base Rate Tranches"), as we may request in accordance with the Note Purchase Agreement. The initial Senior Secured Note issued on the closing bears interest at LIBOR, plus an applicable margin. We may convert the LIBOR Tranche into a Base Rate Tranche in accordance with the Note Purchase Agreement. The Note Purchase Agreement contains customary covenants and default and cross-default provisions.
CCLP Long-Term Debt
CCLP’s Bank Credit Facilities. Under CCLP's bank credit agreement (the "CCLP Credit Agreement"), CCLP and CSI Compressco Sub, Inc. are named as the borrowers and all obligations under the CCLP Credit Agreement are guaranteed by all of CCLP's existing and future, direct and indirect, domestic restricted subsidiaries (other than domestic subsidiaries that are wholly owned by foreign subsidiaries). We are not a borrower or a guarantor under the CCLP Credit Agreement. The CCLP Credit Agreement includes a maximum credit commitment of $400.0 million, and included within such amount is availability for letters of credit (with a sublimit of $20.0 million) and swingline loans (with a sublimit of $60.0 million). As of November 9, 2015, CCLP has a balance outstanding under the CCLP Credit Agreement of $243.0 million, has $0.8 million letters of credit and performance bonds outstanding, and has availability under the CCLP Credit Agreement of $156.2 million.
The CCLP Credit Agreement is available to provide CCLP's working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future expansions or acquisitions. So long as CCLP is not in default, the CCLP Credit Agreement can also be used to fund CCLP’s quarterly distributions at the option of the board of directors of CCLP's general partner (provided, that after giving effect to such distributions, the borrowers will be in compliance with the financial covenants). The maturity date of the CCLP Credit Agreement is August 4, 2019.
Borrowings under the CCLP Credit Agreement bear interest at a rate per annum equal to, at CCLP's option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as selected by CCLP), plus a leverage-based margin or (b) a base rate plus a leverage-based margin; such base rate shall be determined by reference to the highest of (1) the prime rate of interest per annum announced from time to time by Bank of America, N.A. (2) the Federal Funds rate plus 0.50% per annum and (3) LIBOR (adjusted to reflect any required bank reserves) for a one-month interest period on such day plus 1.00% per annum. LIBOR based loans will have an applicable margin that will range between 1.75% and 2.50% per annum and base rate loans will have an applicable margin that will range between 0.75% and 1.50% per annum, each

based on CCLP's consolidated total leverage ratio when financial statements are delivered. In addition to paying interest on outstanding principal under the CCLP Credit Agreement, CCLP is required to pay a commitment fee in respect of the unutilized commitments thereunder at the applicable rate ranging from 0.375% to 0.50% per annum, paid quarterly in arrears based on CCLP's consolidated total leverage ratio. CCLP is also required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans, fronting fees and other fees agreed to with the administrative agent and lenders.
The CCLP Credit Agreement requires CCLP to maintain (i) a minimum consolidated interest coverage ratio (ratio of consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) to consolidated interest charges) of 3.0 to 1.0, (ii) a maximum consolidated total leverage ratio (ratio of consolidated total indebtedness to consolidated EBITDA) of 5.5 to 1.0 (with step downs to 5.0 to 1.0), and (iii) a maximum consolidated secured leverage ratio (consolidated secured indebtedness to consolidated EBITDA) of 4.0 to 1.0, in each case, as of the last day of each fiscal quarter, calculated on a trailing four quarters basis. At September 30, 2015, the CCLP consolidated total leverage ratio was 4.41 to 1. In addition, the CCLP Credit Agreement includes customary negative covenants that, among other things, limit CCLP's ability to incur additional debt, incur, or permit certain liens to exist, or make certain loans, investments, acquisitions, or other restricted payments. The CCLP Credit Agreement provides that CCLP can make distributions to holders of its common units, but only if there is no default or event of default under the facility. CCLP is in compliance with all covenants and conditions of the CCLP Credit Agreement as of September 30, 2015.
All obligations under the CCLP Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first lien security interest in substantially all of CCLP's assets and the assets of its existing and future domestic subsidiaries, and all of the capital stock of its existing and future subsidiaries (limited in the case of foreign subsidiaries, to 65% of the voting stock of first tier foreign subsidiaries).
CCLP 7.25% Senior Notes. In August 2014, CCLP, and CSI Compressco Finance Inc., a Delaware corporation and indirect wholly owned subsidiary of CCLP (CSI Compressco Finance and, together with CCLP, the "Issuers"), issued $350.0 million aggregate principal amount of the Issuers’ 7.25% Senior Notes due 2022 (the "CCLP Senior Notes") in a private offering (the "Offering") exempt from the registration requirements under the Securities Act of 1933, as amended (the "Securities Act") pursuant to a Note Purchase Agreement dated July 29, 2014. The CCLP Senior Notes were subsequently registered through a public exchange offer that closed on July 20, 2015.
The obligations under 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 Securities") were issued pursuant to an indenture described below.
The Obligors issued the CCLP Securities pursuant to the Indenture dated as of August 4, 2014 (the "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, beginning February 15, 2015. The CCLP Senior Notes are scheduled to mature on August 15, 2022.
The 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 Indenture. 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 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 and conditions of the CCLP Senior Note Purchase Agreement as of September 30, 2015.

Other Sources and Uses
In addition to the aforementioned revolving credit facilities, we and CCLP fund our respective short-term liquidity requirements from cash generated by our respective operations, operating 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. 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, the CCLP Credit Agreement matures in August 2019, TETRA's Senior Notes, including the Series 2015 Senior Notes, mature at various dates between April 2016 and November 2022, and the CCLP Senior Notes mature on August 15, 2022. Conditioned upon the closing and funding of the issuance of the Series 2015 Senior Notes, the maturity date of TETRA's Senior Secured Notes will be extended to April 2019. The replacement of these capital sources at similar or more favorable terms is not certain. If it is necessary to issue equity to fund our capital needs, dilution to our common stockholders will occur.
Although near-term growth plans have been suspended and are subject to our efforts to conserve cash and rationalize our cost structure during the current period of low oil and natural gas prices, we maintain a long-term growth strategy for our core businesses. As part of our strategic growth plans, we will evaluate opportunities to acquire businesses and assets that may involve 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. CCLP also continues to pursue its long-term growth objectives, with funding available under its credit facilities, other borrowings, cash generated from the issuance of its common units, as well as its available cash.
CCLP’s Partnership Agreement requires that within 45 days after the end of each quarter, it distribute all of its available cash, as defined in the Partnership Agreement, to its unitholders of record on the applicable record date. During the nine months ended September 30, 2015, CCLP distributed approximately $51.0 million, including approximately $28.3 million to its public unitholders.
Off Balance Sheet Arrangements
As of September 30, 2015, 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.
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.
Environmental
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.
Other Contingencies
Related to its remaining oil and gas property decommissioning liabilities, our Maritech subsidiary estimates the third-party fair values (including an estimated profit) to plug and abandon wells, decommission the pipelines and
46

platforms, and clear the sites, and uses these estimates to record Maritech’s decommissioning liabilities, net of amounts allocable to joint interest owners. Maritech has encountered situations where previously plugged and abandoned wells on its properties have later exhibited a build-up of pressure, which is evidenced by gas bubbles coming from the plugged well head. We refer to this situation as “wells under pressure” and this can either be discovered when performing additional work at the property or by notification from a third party. Wells under pressure require Maritech to return to the site to perform additional plug and abandonment procedures that were not originally anticipated and included in the estimate of the asset retirement obligation for such property. Remediation work at previously abandoned well sites is particularly costly, due to the lack of a platform from which to base these activities. Maritech is the last operator of record for its plugged wells, and bears the risk of additional future work required as a result of wells becoming pressurized in the future.
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. For oil and gas properties Maritech previously operated, the buyers of the properties assumed the financial responsibilities associated with the properties' operations, including abandonment and decommissioning, and generally became the successor operator. Some buyers of these Maritech properties subsequently sold certain of these properties to other buyers who also assumed these financial responsibilities associated with the properties' operations, and these buyers also typically became the successor operator of the properties. To the extent that a buyer of these properties fails to perform the abandonment and decommissioning work required, the previous owner, including Maritech, may be required to perform the abandonment and decommissioning obligation. A significant portion of the decommissioning liabilities that were assumed by the buyers of the Maritech properties in 2011 remains unperformed and we believe the amounts of these remaining liabilities are significant. We monitor the financial condition of the buyers of these properties from Maritech, and if current oil and natural gas pricing levels continue, we expect that one or more of these buyers may be unable to perform the decommissioning work required on the properties acquired from Maritech.
During the nine months ended September 30, 2015, continued low oil and natural gas prices have resulted in reduced revenues and cash flows for all oil and gas producing companies, including those companies that bought Maritech properties in the past. Certain of these oil and gas producing companies that bought Maritech properties are currently experiencing severe financial difficulties. With regard to certain of these properties, Maritech has security in the form of bonds or cash escrows intended to secure the buyers' obligations to perform the decommissioning work. One company that bought, and subsequently sold, Maritech properties filed for Chapter 11 bankruptcy protection in August 2015. Maritech and its legal counsel monitor the status of these companies.
Contractual Obligations
The table below summarizes our consolidated contractual cash obligations as of September 30, 2015:

(1) | We have estimated the timing of these payments for decommissioning liabilities based upon our plans and the plans of outside operators, which are subject to many changing variables, including the estimated life of the producing oil and gas properties, which is affected by changing oil and gas commodity prices. The amounts shown represent the discounted obligation as of September 30, 2015.

(2) | Amounts exclude other long-term liabilities reflected in our Consolidated Balance Sheet that do not have known payment streams. These excluded amounts include approximately $4.1 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 settlements.

47

Our consolidated contractual obligations and commitments principally consist of obligations associated with our outstanding indebtedness, CCLP's outstanding indebtedness, product purchase obligations, decommissioning and other asset retirement obligations, and obligations under operating and capital leases. On March 18, 2015, we entered into a Note Purchase Agreement (the "Note Purchase Agreement") with Wells Fargo Energy Capital, Inc., in its capacity as noteholder representative for the noteholders (the "Noteholder Representative"), and Wells Fargo Energy Capital, Inc., in its capacity as the sole initial purchaser. The Note Purchase Agreement relates to the issuance and sale of $50.0 million aggregate principal amount of Senior Secured Notes due April 1, 2017 (the "Senior Secured Notes").
For additional information about our contractual obligations as of December 31, 2014, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our annual Report on Form 10-K for the year ended December 31, 2014.
Cautionary Statement for Purposes of Forward-Looking Statements
This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements in this quarterly report are identifiable by the use of words and other similar words: “anticipates", "assumes", “believes,” "budgets", “could,” “estimates,” "expects", "forecasts", "goal", "intends", "may", "might", "plans", "predicts", "projects", "schedules", "seeks", "should", "targets", "will", and "would".
Such forward-looking statements reflect our current views with respect to future events and financial performance and are based on assumptions that we believe to be reasonable but such forward-looking statements
are subject to numerous risks, and uncertainties, including, but not limited to:

• | economic and operating conditions that are outside of our control, including the supply, demand, and prices of crude oil and natural gas;

• | the levels of competition we encounter;

• | our operational performance;

• | risks related to acquisitions and our growth strategy;

• | the availability of raw materials and labor at reasonable prices;

• | risks related to our foreign operations;

• | the effect and results of litigation, regulatory matters, settlements, audits, assessments, and contingencies; and

• | other risks and uncertainties under “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014, 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.

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 2, 2015. 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.
Interest Rate Risk
Through September 30, 2015, there have been no material changes pertaining to our interest risk rate exposures as disclosed in our Form 10-K for the year ended December 31, 2014.
Exchange Rate Risk
As of September 30, 2015, 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, 2014.
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 September 30, 2015, the end of the period covered by this quarterly report.
We are currently integrating CSI 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 CSI business, which we expect to be completed in fiscal year 2015.
Other than the changes described above, there were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2015, 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.

Item 1A. Risk Factors.
There have been no material changes in the information pertaining to our Risk Factors as disclosed in our Form 10-K for the year ended December 31, 2014, except for the following:
We may have continuing exposure on abandonment and decommissioning obligations associated with oil and gas properties sold by Maritech.
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 having a value at the time of sale of approximately $122.0 million pursuant to the purchase and sale agreements. For oil and gas properties Maritech previously operated, the buyer of the properties assumed the financial responsibilities associated with the properties' operations, including abandonment and decommissioning, and generally became the successor operator. Some buyers of these Maritech properties subsequently sold certain of these properties to other buyers who also assumed the financial responsibilities associated with the properties' operations, and these buyers also typically became the successor operator of the properties. To the extent that a buyer of these properties fails to perform the abandonment and decommissioning work required, the previous owner, including Maritech, may be required to perform the abandonment and decommissioning obligation. A significant portion of the decommissioning liabilities that were assumed by the buyers of the Maritech properties in 2011 remains unperformed and we believe the amounts of these remaining liabilities are significant. We monitor the financial condition of the buyers of these properties from Maritech, and if current oil and natural gas pricing levels continue, we expect that one or more of these buyers may be unable to perform the decommissioning work required on properties they acquired from Maritech. To the extent Maritech is required to perform a significant portion of the abandonment and decommissioning obligations associated with these previously owned oil and gas properties, our financial condition and results of operations may be negatively affected.
During the nine months ended September 30, 2015, continued low oil and natural gas prices have resulted in reduced revenues and cash flows for all oil and gas producing companies, including those companies that bought Maritech properties in the past. Certain of these oil and gas producing companies that bought Maritech properties are currently experiencing severe financial difficulties. With regard to certain of these properties, Maritech has security in the form of bonds or cash escrows intended to secure the buyers' obligations to perform the decommissioning work. One company that bought, and subsequently sold, Maritech properties filed for Chapter 11 bankruptcy protection in August 2015. Maritech estimates that of the total amount of decommissioning liabilities associated with properties sold to this company, Maritech is exposed to a high level of risk on properties that had decommissioning liabilities at the time they were sold in 2011 of approximately $6 million. This amount, which is net to Maritech's interest, may not be representative of the current fair value of these obligations and does not reflect the potential benefit of bonding that may be available to Maritech if it were to be required to perform such obligations. Maritech and its legal counsel monitor the status of these companies. There can be no assurance that Maritech will not become legally responsible to perform decommissioning work on properties it previously sold, resulting in charges to our future earnings and increases to our future operating cash requirements.
We are exposed to significant credit risks.
We face credit risk associated with the significant amounts of accounts receivable we have with our customers in the energy industry. Many of our customers, particularly those associated with our onshore operations, are small- to medium-sized oil and gas operators that may be more susceptible to fluctuating oil and gas commodity prices or generally increased operating expenses than larger companies. Our ability to collect from our customers is impacted by the current decreased oil and natural gas price environment.
As the owner and operator of its oil and gas property interests, Maritech is liable for the proper abandonment and decommissioning of these properties. We have guaranteed a portion of the abandonment and decommissioning liabilities of Maritech. With respect to certain properties, Maritech is entitled to be paid in the future for all or a portion of these obligations by the previous owner of the property once the liability is satisfied. We and Maritech are subject to the risk that the previous owner(s) will be unable to make these future payments. In addition, for certain remaining Maritech properties to be decommissioned or abandoned, the co-owners of such properties are responsible for the payment of their portions of the associated operating expenses and abandonment liabilities. However, if one or more co-owners do not pay their portions, Maritech and any other nondefaulting co-
50

owners may be liable for the defaulted amount. If any required payment is not made by a previous owner or a co-owner and any security is not sufficient to cover the required payment, we could suffer material losses.
During the nine months ended September 30, 2015, continued decreased oil and natural gas prices have resulted in reduced revenues and cash flows for oil and gas producing companies, including companies that are joint-owners in Maritech oil and gas properties and decommissioning obligations currently owned or from whom Maritech is entitled to receive payments upon satisfaction of certain decommissioning obligations. Certain of these previous owners of Maritech properties who are obligated to pay Maritech in the future are currently experiencing severe financial difficulties, including one company which filed for bankruptcy protection during the third quarter of 2015. The majority of the amounts owed to Maritech by these companies are not contractually required to be paid to Maritech until several years in the future. Nevertheless, we are monitoring the financial condition of this company, and if current oil and natural gas pricing levels continue, this company may be unable to pay Maritech for contractual amounts owed. Maritech and its outside counsel will take any action necessary to protect Maritech's interests. Although certain of these decommissioning obligations may not be performed for many years, there can be no assurance that the current oil and gas price environment will not result in charges to our future earnings and increases to our future operating cash requirements.
