Discontinued Operations and Disposal Groups [Abstract] |
Discontinued Operations | DISCONTINUED OPERATIONS On January 29, 2021, we entered into the Purchase and Sale Agreement with Spartan pursuant to which we sold the general partner of CSI Compressco, including the IDRs in CSI Compressco and approximately 23.1% of the outstanding limited partner interests in CSI Compressco. As a result of these transactions, we no longer consolidate CSI Compressco as of January 29, 2021. We recognized a primarily non-cash accounting gain of $120.1 million during the year ended December 31, 2021 related to the GP Sale. The gain is included in income (loss) from discontinued operations, net of taxes in our consolidated statement of operations. We also provided back-office support to CSI Compressco under a Transition Services Agreement for one year until CSI Compressco completed a full separation from our back-office support functions. During the year ended December 31, 2021, we received $7.0 million from CSI Compressco for services provided under the Transition Services Agreement and other reimbursements and paid $0.5 million to CSI Compressco for reimbursement of expenses. Our interest in CSI Compressco and the general partner represented substantially all of our Compression Division. In addition, on March 1, 2018, we closed a series of related transactions that resulted in the disposition of our Offshore Division, consisting of our Offshore Services and Maritech segments. Our former Compression and Offshore Divisions are reported as discontinued operations for all periods presented. Our consolidated balance sheets and consolidated statements of operations report discontinued operations separate from continuing operations. Our consolidated statements of comprehensive income, statements of equity and statements of cash flows combine continuing and discontinued operations. Our current-year consolidated statement of operations, statement of comprehensive income, statement of equity and statement of cash flows include CSI Compressco activity for January 1 through January 29. Our consolidated statements of cash flows for the years ended December 31, 2021, 2020 and 2019 included $3.0 million, $14.7 million and $75.8 million, respectively, of capital expenditures related to our former Compression division. Our consolidated statements of cash flows also included $411.1 million of proceeds from long-term debt, $413.1 million of payments of long-term debt, $19.4 million from proceeds from sale of property, plant and equipment, $4.9 million of debt exchange expenses and $2.6 million from amortization of deferred financing discounts, costs and gains for the year ended December 31, 2020, and included $45.0 million of proceeds from long-term debt, $41.6 million of payments of long-term debt, $11.0 million from proceeds from sale of property, plant and equipment, and $2.6 million from amortization of deferred financing discounts, costs and gains for the year ended December 31, 2019. Our current-year results do not include CSI Compressco depreciation or amortization as the assets were considered held for sale. A summary of financial information related to our discontinued operations is as follows: Reconciliation of the Line Items Constituting Pretax Loss from Discontinued Operations to the After-Tax Loss from Discontinued Operations (in thousands)
