Share-Based Compensation. Our share-based compensation plan provides the ability to grant equity awards to our employees, consultants and non-employee directors. As of December 31, 2018, only nonqualified stock options, restricted shares, performance stock and restricted share units had been granted under such plans. The fair value of restricted share grants and restricted share units is based on the closing price of our common stock on the grant date. We values option grants based on the grant date fair value using the Black-Scholes option-pricing model, and we value performance awards with market conditions based on the grant date fair value using a Monte Carlo simulation, both of which require the use of subjective assumptions. We recognize share-based compensation expense on a straight-line basis over the requisite service period for the entire award and makes estimates of employee terminations and forfeiture rates which impacts the amount of compensation expense that is recorded over the requisite service period.

Income Taxes. We are subject to income and other similar taxes in all areas in which we operate. When recording income tax expense, certain estimates are required because: (a) income tax returns are generally filed months after the close of our annual accounting period; (b) tax returns are subject to audit by taxing authorities and audits can often take years to complete and settle; and (c) future events often impact the timing of when we recognize income tax expenses and benefits.

We account for income taxes utilizing the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities due to a change in tax rates is recognized as income or expense in the period that includes the enactment date.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In assessing the likelihood and extent that deferred tax assets will be realized, consideration is given to projected future taxable income and tax planning strategies. A valuation allowance is recorded when, in the opinion of management, it is more likely than not that a portion or all of the deferred tax assets will not be realized.

We have federal, state and international net operating losses ("NOLs") carried forward from tax years ending before January 1, 2018 that will expire in the years 2020 through 2038. Due to U.S. tax reform, any U.S. federal income tax losses incurred for tax years beginning after December 31, 2017 can be carried forward indefinitely with no carry back available. In addition, the taxable losses generated in tax years beginning after December 31, 2017 can only offset 80% of taxable income generated in tax years beginning after December 31, 2018. After considering the scheduled reversal of deferred tax liabilities, projected future taxable income, the potential limitation on use of NOLs under Section 382 of the Internal Revenue Code of 1986, as amended (the "Code") and tax planning strategies, we established a valuation allowance due to the uncertainty regarding the ultimate realization of the deferred tax assets associated with its NOL carryforwards.

As a result of the Chapter 11 Proceeding, on the Plan Effective Date, we believe we experienced an ownership change for purposes of Section 382 of the Code because of its Restructuring Plan. Consequently, our pre-change NOLs are subject to an annual limitation (See Note 14 - Chapter 11 Proceeding and Emergence for additional information, including definitions of capitalized defined terms, about the Chapter 11 Proceeding and emergence from the Chapter 11 Proceeding). The ownership change and resulting annual limitation on use of NOLs are not expected to result in the expiration of our NOL carryforwards if we are able to generate sufficient future taxable income within the carryforward periods. However, the limitation on the amount of NOLs available to offset taxable income in a specific year may result in the payment of income taxes before all NOLs have been utilized. Additionally, a subsequent ownership change may result in further limitation on the ability to utilize existing NOLs and other tax attributes, which could cause our pre-change NOL carryforwards to expire unused.

We recognize the financial statement effects of a tax position when it is more-likely-than-not, based on the technical merits, that the position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is measured as the largest amount of tax benefit that is greater than 50.0% likely of being realized upon ultimate settlement with a taxing authority. Previously recognized uncertain tax positions are reversed in the first period in which it is more-likely-than-not that the tax position would be sustained upon examination. Income tax related interest and penalties, if applicable, are recorded as a component of the provision for income tax expense. For the year ended December 31, 2018, we have an unrecognized tax benefit of \$6.0 million related to an increase in the estimate of the reserve for unrecognized tax benefits relating to our uncertain tax positions, which is netted against our net operating loss carryforwards. The unrecognized tax benefit, or UTB, is related to a deduction for certain fees that were paid using shares of our common stock as part of the January 7, 2017 plan of reorganization. The recorded unrecognized tax benefit is equal to our estimate of the portion of the tax benefit that is less than 50% likely to be realized upon ultimate settlement with a taxing

authority.

# Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU No. 2016-02 seeks to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. Unlike current U.S. GAAP, which requires only capital leases to be recognized on the balance sheet, ASU No. 2016-02 will require both operating and finance leases to be recognized on the balance sheet. Additionally, the new guidance will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements.

The amendments in ASU No. 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early application is permitted. We adopted this new accounting standard on January 1, 2019 using the modified retrospective approach. Under this transition method, leases existing at, or entered into after the adoption date are required to be recognized and measured. We have elected to use the effective date as its date of initial application, consequently prior period amounts have not been adjusted and continue to be reflected in accordance with historical accounting. We elected the package of practical expedients which permits us to not reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We have also elected the practical expedient to combine the lease and non-lease components of a contract for all of our contracts, as well as the short-term lease recognition exemption.

The adoption of this standard will result in the initial recognition of approximately \$25.0 million to \$28.0 million of right-of-use assets and operating lease liabilities, with no related impact to consolidated stockholders' equity or net income (loss).

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends U.S. GAAP by introducing a new impairment model for financial instruments that is based on expected credit losses rather than incurred credit losses. The new impairment model applies to most financial assets, including trade accounts receivable. The amendments in ASU 2016-13 are effective for interim and annual reporting periods beginning after December 15, 2019, although it may be adopted one year earlier, and requires a modified retrospective transition approach. We are currently evaluating the impact this standard will have on our results of operations and financial position.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ("ASU 2016-16"), which requires an entity to recognize the income tax consequences of an intra-entity asset transfer, other than an intra-entity asset transfer of inventory, when the transfer occurs. The ASU is effective for the interim and annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years, and early application is permitted. We adopted this new accounting standard on January 1, 2018, and upon adoption recognized a cumulative effect adjustment as a reduction to retained earnings of \$13.2 million.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which establishes a one-step process for testing goodwill for impairment. This ASU is effective for the interim and annual reporting periods beginning after December 15, 2019 and early adoption is permitted. We early adopted this new accounting standard on January 1, 2018 and there no impact on our consolidated financial statements upon adoption. As part of our annual impairment assessment of goodwill during the fourth quarter of 2018, we applied this new accounting standard and recognized an impairment charge of \$146.0 million for the year ended December 31, 2018.

In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Ef ects from Accumulated Other Comprehensive Income ("ASU 2018-02"), which allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and requires certain disclosures about stranded tax effects. This ASU is effective for the interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently evaluating the impact of this standard on our consolidated financial statements.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staf Accounting Bulletin No. 118, ("ASU 2018-05"), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act (the Tax Act) pursuant to Staff Accounting Bulletin No. 18, which allows companies to
