Provisions set aside for warranty exposures either relate to amounts provided systematically based on historical experience under contractual warranty obligations or specific provisions created in respect of individual customer issues undergoing commercial resolution and negotiation. Amounts set aside represent Management’s best estimate of the likely settlement and the timing of any resolution with the relevant customer.

In a business acquisition, the Company may acquire assets and assume certain liabilities of an acquired entity. Estimates are made as to the fair value of property, plant and equipment, intangible assets, and goodwill, among other items. In certain circumstances, such as the valuation of property, plant and equipment and intangible assets acquired, the Company relies on independent third-party valuators. The determination of these fair values involves a variety of assumptions, including revenue growth rates, projected cash flows, customer attrition rates, operating margins, discount rates, and economic lives.

Property, plant and equipment, energy infrastructure assets and intangible assets are stated at cost less accumulated depreciation and accumulated amortization and any impairment losses. Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property, plant and equipment, energy infrastructure assets and intangible assets is reviewed on an annual basis. Assessing the reasonableness of the estimated useful lives of property, plant and equipment, energy infrastructure assets and intangible assets requires judgment and is based on currently available information. Property, plant and equipment, energy infrastructure assets and intangible assets are also reviewed for potential impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Changes in circumstances, such as technological advances and changes to business strategy can result in actual useful lives differing significantly from estimates. The assumptions used, including rates and methodologies, are reviewed on an ongoing basis to ensure they continue to be appropriate. Revisions to the estimated useful lives of property, plant and equipment, energy infrastructure assets and intangible assets constitutes a change in accounting estimate and are applied prospectively.

In calculating the value of the Company’s finance lease receivables, the Company is required to determine the fair value of the underlying assets included in the finance lease transaction, or, if lower, the present value of the lease payments discounted using a market rate of interest. The fair value of the underlying assets should reflect the amount that the Company would otherwise recognize on a sale of those assets.

Amounts included in allowance for doubtful accounts reflect the full lifetime expected credit losses for trade receivables. The Company determines allowances based on Management’s best estimate of future expected credit losses, considering historical default rates, current economic conditions, and forecasts of future economic conditions. Future economic conditions, especially around the oil and gas industry, may have a significant impact on the collectability of trade receivables from customers and the corresponding expected credit losses. Management has implemented additional monitoring processes in assessing the creditworthiness of customers and believes the current provision appropriately reflects the best estimate of its future expected credit losses. Significant or unanticipated changes in economic conditions could impact the magnitude of future expected credit losses.

The Company regularly reviews the nature and quantities of inventory on hand and evaluates the net realizable value of items based on historical usage patterns, known changes to equipment or processes, and customer demand for specific products. Significant or unanticipated changes in business conditions could impact the magnitude and timing of impairment recognized.

Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could necessitate future adjustments to taxable income. The Company establishes provisions for uncertain tax positions, based on reasonable estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective company’s domicile. The Company reviews the adequacy of these provisions at the end of each reporting period and adjusts them as required. However, it is possible that, at some future date, current income tax liabilities are in excess of the Company’s current income tax provision as a result of these audits, adjustments, or litigation with tax authorities. These differences could materially impact the Company’s assets, liabilities, and net income.

Deferred tax assets are recognized for all unused tax losses, carried forward tax credits, or other deductible temporary differences to the extent that it is probable that taxable profit will be available against which these deferred tax assets can be utilized. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing of reversal, expiry of losses and the level of future taxable profits together with future tax planning strategies. The basis for this estimate is Management’s cash flow projections. To the extent the Company determines the recoverability of deferred tax assets is unlikely, the deferred tax asset is not recognized. Management regularly assesses the unrecognized deferred tax asset to determine what portion can be recognized in response to changing economic conditions or recent events.

The Company employs the fair value method of accounting for stock options and phantom share entitlement. The determination of the share-based compensation expense for stock options and phantom share entitlement requires the use of estimates and assumptions based on exercise prices, market conditions, vesting criteria, length of employment, and past experiences of the Company. Changes in these estimates and future events could alter the determination of the provision for such compensation. Details concerning the assumptions used are described in Note 25.

Government grants are recognized when there is reasonable assurance that the grant will be received, and all conditions associated with the grant are met. If a grant is received, but reasonable assurance and compliance with conditions is not achieved, the grant is recognized as a deferred liability until the conditions are fulfilled. As long as the Company is eligible for any such programs the grants received are recorded as a reduction against the associated expenses to which they relate and in the period the expenses are recognized.

During the fourth quarter of 2022, the Company reassessed its operating and reporting segments. Prior to this assessment, the Company’s operating and reporting segments were one and the same, with those segments being Canada, USA, and Rest of World. With the completion of the Exterran acquisition Management noted a change in how the Chief Operating Decision Maker (“CODM”) views the organization. On this basis, four operating segments have been identified with no change in the Canada and USA segments, while Rest of World has been bifurcated into LATAM and EH. For external reporting purposes, Enerflex’s reportable segments are as follows:
