Certain reclassifications have been made to prior period amounts to conform to the current period presentation. A majority of the reclassifications were related to the discontinued operations. These reclassifications do not impact net income (loss) and do not reflect a material change to the information previously presented in our consolidated financial statements.

Preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management uses historical and other pertinent information to determine these estimates. Actual results could differ from those estimates. Areas where critical accounting estimates are made by management include litigation and self-insured risk reserves.

Basic estimates its reserves related to litigation and self-insured risks based on the facts and circumstances specific to the litigation and self-insured claims and its past experience with similar claims. Basic maintains accruals in the consolidated balance sheets to cover self-insurance retentions. Please see Note 9. Commitments and Contingencies for further discussion.

Basic accounts for revenues under Accounting Standards Codification (ASC) Topic - 606 - Revenue from Contracts with Customers, the core principle of which is that a company should recognize revenue to match the delivery of goods or services to customers to the consideration the company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of revenue and cash flows arising from contracts with customers. We adopted the standard effective January 1, 2018, using the modified retrospective method. Other than additional required disclosures, adoption of the new standard did not have a significant impact on our consolidated financial statements.

Our revenues are generated by services, which are consumed as provided by our customers on their sites. As a decentralized organization, contracts for our services are negotiated on a regional level and are on a per job basis, with jobs being completed in a short period of time, usually one day or up to a week. Revenue is recognized as performance obligations have been completed on a daily basis either as Accounts Receivable or Work-in-Process ("WIP"), when all of the proper approvals are obtained. A small percentage of our jobs may require performance obligations which extend over a longer period of time and are not invoiced until all performances obligations in the contract are complete, such as, drilling or plugging a well, fishing services, and pad site preparation jobs. Because these jobs are performed on the customer's job site, and we are contractually entitled to bill for our services performed to date, revenues for these service lines are recognized on a daily basis as services are performed and recorded as Contract Assets rather than WIP or Accounts Receivable. Contract Assets are typically invoiced within 30 to 60 days of recognizing revenue. Basic does not have any long-term service contracts; nor do we have revenue expected to be recognized in any future year related to remaining performance obligations or contracts with variable consideration related to undelivered performance obligations.

For rental and fishing tools, inventories consisting mainly of grapples, controls and drill bits are stated at lower of cost or net realizable value. Other inventories, consisting mainly of manufacturing raw materials, rig components, repair parts, drilling and completion materials and gravel, are held for use in the operations of Basic and are stated at lower of cost or net realizable value, with cost being determined on the first-in, first-out (“FIFO”) method.

Basic estimates its allowance for losses on accounts receivable based on past collections and expectations for future collections. Basic regularly reviews accounts for collectability. After all collection efforts are exhausted, if the balance is still determined to be uncollectable, the balance is written off. Expense related to the write off of uncollected accounts is recorded in general and administrative expense.

Financial instruments, which potentially subject Basic to concentration of credit risk, consist primarily of temporary cash investments and trade receivables. Basic restricts investment of temporary cash investments to financial institutions with high credit standing. Basic’s customer base consists primarily of multi-national and independent oil and natural gas producers. It performs ongoing credit evaluations of its customers but generally does not require collateral on its trade receivables. Credit risk is considered by management to be limited due to the large number of customers comprising its customer base. Basic maintains an allowance for potential credit losses on its trade receivables. For the twelve months ended December 31, 2019, one customer represented 12% of consolidated revenue.

Basic determines if an arrangement is a lease at inception of the arrangement. To the extent that we determine an arrangement represents a lease, we classify that lease as an operating lease or a finance lease. We capitalize operating leases on our consolidated balance sheets through a right-of-use (“ROU”) asset and a corresponding lease liability. ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease.

Operating leases are included in operating lease ROU assets, current operating lease liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at the commencement date of an arrangement based on the present value of lease payments over the lease term. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. Basic adopted this standard on January 1, 2019.

Property and equipment are stated at cost or at estimated fair value at acquisition date if acquired in a business combination or remeasured as a result of fresh start accounting. Expenditures for repairs and maintenance are charged to expense as incurred and additions and improvements that significantly extend the lives of the assets are capitalized. Upon sale or other retirement of depreciable property, the cost and accumulated depreciation and amortization are removed from the related accounts and any gain or loss is reflected in operations. All property and equipment are depreciated or amortized (to the extent of estimated salvage values) on the straight-line method and the estimated useful lives of the assets are as follows:


Asset Type:			Useful Life
Buildings and improvements			20-30 years
Well service units and equipment			3-15 years
Fluid services equipment			5-10 years
Brine and fresh water stations			15 years
Fracturing/test tanks			10 years

Disposal facilities			10-15 years
Vehicles			3-7 years
Rental equipment			2-15 years

Software and computers			3 years

The components of a well servicing rig generally require replacement or refurbishment during the well servicing rig’s life and are depreciated over their estimated useful lives, which ranges from 3 to 15 years. The costs of the original components of a purchased or acquired well servicing rig are not maintained separately from the base rig.

We perform a review of our asset groups for impairment when, in management’s judgment, events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recovered over its remaining service life. Impairment is indicated when the sum of the estimated future cash flows, on an undiscounted basis, is less than the asset groups carrying amount. When impairment is identified and fair value is less than carrying value, an impairment charge is recorded to income based on an estimated fair value generally determined based on an estimate of future cash flows on a discounted basis. See Note 4. Property and Equipment for disclosures related to our tangible and intangible property impairments in 2019 and 2018.

Amortization expense for each of the years ended December 31, 2019 and 2018 was approximately $0.2 million. Basic evaluates intangible assets for impairment annually. In 2019, the Company wrote off $0.2 million of net trade names related to the discontinued pumping services line of business.

Basic capitalizes certain third-party fees directly related to the issuance of debt and amortizes these costs over the life of the debt using the effective interest method. Debt issuance costs related to our ABL Facility are presented net of amortization as a non-current asset. Debt issuance costs related to our Senior Secured Notes and Term Loan are presented net of amortization as an offset to the liability. Amortized debt issuance costs are included in interest expense and totaled $2.3 million in 2019, and $1.1 million in 2018.

Basic has historically compensated our directors, executives and employees using a combination of performance and time-based stock option, restricted share, and restricted share unit awards. Basic accounts for share-based payment awards under Accounting Codification Standard 718 - Compensation - Stock Compensation (ASC 718), which requires that the value of the awards is established at the date of the grant and is expensed over the vesting period of the grant. The method of determining the fair value of share-based payments depends on the type of award. Share-based awards that vest over a certain service period with no market conditions are valued at the closing market price on the grant date. Share-based awards that are dependent upon certain market performance and service conditions being met are valued using a Monte Carlo simulation model with model inputs that are determined on the date of the grant. Option grants are valued using the Black-Scholes-Merton model using model inputs that are determined on the date of the grant. Once the per-share fair value on the grant date is established, the aggregate expense of the grant is recognized on a straight-line basis over the vesting period of the grant.

Basic is required to record the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets and capitalize an equal amount as a cost of the asset depreciating it over the life of the asset. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each quarter to reflect the passage of time, changes in the estimated future cash flows underlying the obligation, acquisition or construction of assets, and settlements of obligations. Basic has asset retirement obligations related to our saltwater disposal facilities, brine and freshwater wells.

Basic is subject to extensive federal, state and local environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and may require Basic to remove or mitigate the adverse environmental effects of disposal or release of petroleum, chemical and other substances at various sites. Environmental expenditures are expensed or capitalized depending on the future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a non-capital nature are recorded when environmental assessment and/or remediation is probable and the costs can be reasonably estimated.

The provision for income taxes is determined using the asset and liability method of accounting for income taxes based on the authoritative accounting guidance. Deferred tax assets and liabilities are recorded based upon differences between the tax basis of assets and liabilities and their carrying values for financial reporting purposes, and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We record net deferred tax assets to the extent we believe these assets will more likely than not be

realized. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of net recorded amount, we would make an adjustment to the valuation allowance which would reduce the provision for income taxes.

In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard was adopted effective January 1, 2019. See Note 6. Leases for further discussion.

In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, "Financial Instruments–Credit Losses," and subsequent amendment to the initial guidance, ASU 2018-19 (collectively, Topic 326). ASU 2016-13 amends current measurement techniques used to estimate credit losses for financial assets. The amendments in ASU 2016-13 are effective for financial statements issued for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Basic adopted this standard on January 1, 2020, and the adoption did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract." ASU 2018-15 requires implementation costs incurred by customers in cloud computing arrangements to be deferred over the noncancellable term of the cloud computing arrangements plus any optional renewal periods (1) that are reasonably certain to be exercised by the customer or (2) for which exercise of the renewal option is controlled by the cloud service provider. The effective date of this pronouncement is for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, and early adoption is permitted. The standard can be adopted either using the prospective or retrospective transition approach. Basic adopted this standard on September 30, 2019, and the adoption did not have a material impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 intends to simplify various aspects related to accounting for income taxes and removes certain exceptions to the general principles in the standard. Additionally, the ASU clarifies and amends existing guidance to improve consistent application of its requirements. The amendments of the ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. Basic is currently evaluating the impact of this pronouncement on its consolidated financial statements.
