REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of North American Energy Partners Inc.
Opinion on Internal Control Over Financial Reporting
We have audited North American Energy Partners Inc.’s (the “Company”)’s internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Report on the Consolidated Financial Statements
We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2017, and 2016, the related consolidated statements of operations and comprehensive income (loss), changes in shareholders’ equity and cash flows for the years then ended, and the related notes (collectively referred to as the "consolidated financial statements") and our report dated February 13, 2018 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting in the accompanying Management’s Discussion and Analysis. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission

and the PCAOB and in accordance with the ethical requirements that are relevant to our audit of the financial statements in Canada.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017, and 2016, and its financial performance and its cash flows for the years then ended, in conformity with US generally accepted accounting principles.

We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial

Notes to Consolidated Financial Statements
For the years ended December 31, 2017 and 2016
(Expressed in thousands of Canadian Dollars, except per share amounts or unless otherwise specified)
1. Nature of operations
North American Energy Partners Inc. (the “Company”), formerly NACG Holdings Inc., was incorporated under the Canada Business Corporations Act on October 17, 2003. On November 26, 2003, the Company purchased all the issued and outstanding shares of North American Construction Group Inc. (“NACGI”), including subsidiaries of NACGI, from Norama Ltd. which had been operating continuously in Western Canada since 1953. The Company had no operations prior to November 26, 2003. The Company provides a wide range of mining and heavy construction services to customers in the resource development and industrial construction sectors, primarily within Western Canada.
2. Significant accounting policies
a) Basis of presentation
These consolidated financial statements are prepared in accordance with United States generally accepted accounting principles ("US GAAP"). Material inter-company transactions and balances are eliminated upon consolidation. These consolidated financial statements include the accounts of the Company, its wholly-owned, Canadian incorporated subsidiaries, NACGI, North American Fleet Company Ltd., North American Construction Holdings Inc. (“NACHI”) and NACG Properties Inc., and the following 100% owned, Canadian incorporated subsidiaries of NACHI as of December 31, 2017:

• North American Engineering Inc. |  | • North American Site Development Ltd.
• North American Enterprises Ltd. |  | • North American Maintenance Ltd.
• North American Mining Inc. |  | • North American Tailings and Environmental Ltd.
• North American Services Inc. |  | • 1753514 Alberta Ltd.

North American Enterprises Ltd. holds a 49% ownership interest in the assets, liabilities, revenue and expenses of a partnership agreement under the name Dene North Site Services. The Company records its share of the partnership assets, liabilities, revenues and expenses within its consolidated financial statements using the proportionate consolidation method (note 24).
b) Use of estimates
The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures reported in these consolidated financial statements and accompanying notes and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Significant estimates made by management include the assessment of the percentage of completion on time-and-materials, unit-price, lump-sum and cost-plus contracts with defined scope (including estimated total costs and provisions for estimated losses) and the recognition of claims and change orders on revenue contracts; assumptions used in impairment testing; and, estimates and assumptions used in the determination of the allowance for doubtful accounts, the recoverability of deferred tax assets and the useful lives of property, plant and equipment and intangible assets.
The accuracy of the Company’s revenue and profit recognition in a given period is dependent on the accuracy of its estimates of the cost to complete for each project. Cost estimates for all significant projects use a detailed “bottom up” approach and the Company believes its experience allows it to provide reasonably dependable estimates. There are a number of factors that can contribute to changes in estimates of contract cost and profitability that are recognized in the period in which such adjustments are determined. The most significant of these include:

• | the completeness and accuracy of the original bid;

• | costs associated with added scope changes;

• | extended overhead due to owner, weather and other delays;

• | subcontractor performance issues;

• | changes in economic indices used for the determination of escalation or de-escalation for contractual rates on long-term contracts;

5 | 2017 Consolidated Financial Statements

NOA

• | changes in productivity expectations;

• | site conditions that differ from those assumed in the original bid;

• | contract incentive and penalty provisions;

• | the availability and skill level of workers in the geographic location of the project; and

• | a change in the availability and proximity of equipment and materials.

The foregoing factors as well as the mix of contracts at different margins may cause fluctuations in gross profit between periods. With many projects of varying levels of complexity and size in process at any given time, changes in estimates can offset each other without materially impacting the Company’s profitability. Major changes in cost estimates, particularly in larger, more complex projects, can have a significant effect on profitability.
c) Revenue recognition
The Company performs its projects under the following types of contracts: time-and-materials; cost-plus; unit-price; and lump-sum. Revenue is recognized as costs are incurred for time-and-materials, unit-price and cost-plus service contracts with no clearly defined scope. Revenue on cost-plus, unit-price, lump-sum and time-and-materials contracts with defined scope is recognized using the percentage-of-completion method, measured by the ratio of costs incurred to date to estimated total costs. The estimated total cost of the contract and percent complete is determined based upon estimates made by management. The costs of items that do not relate to performance of
contracted work, particularly in the early stages of the contract, are excluded from costs incurred to date. The resulting percent complete methodology is applied to the approved contract value to determine the revenue recognized. Customer payment milestones typically occur on a periodic basis over the period of contract completion.
The length of the Company’s contracts varies from less than one year for typical contracts to several years for certain larger contracts. Contract project costs include all direct labour, material, subcontract and equipment costs and those indirect costs related to contract performance such as indirect labour and supplies. General and administrative expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in project performance, project conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and revenue that are recognized in the period in which such adjustments are determined. Profit incentives are included in revenue when their realization is reasonably assured.
Once a project is underway, the Company will often experience changes in conditions, client requirements, specifications, designs, materials and work schedule. Generally, a “change order” will be negotiated with the customer to modify the original contract to approve both the scope and price of the change. Occasionally, however, disagreements arise regarding changes, their nature, measurement, timing and other characteristics that impact costs and revenue under the contract. When a change becomes a point of dispute between the Company and a customer, the Company will then consider it as a claim.
Costs related to unapproved change orders and claims are recognized when they are incurred.
Revenues related to unapproved change orders and claims are included in total estimated contract revenue only to the extent that contract costs related to the claim have been incurred and when it is probable that the unapproved change order or claim will result in:

• | a bona fide addition to contract value; and

• | revenues can be reliably estimated.

These two conditions are satisfied when:

• | the contract or other evidence provides a legal basis for the unapproved change order or claim, or a legal opinion is obtained providing a reasonable basis to support the unapproved change order or claim;

• | additional costs incurred were caused by unforeseen circumstances and are not the result of deficiencies in the Company’s performance;

• | costs associated with the unapproved change order or claim are identifiable and reasonable in view of work performed; and

• | evidence supporting the unapproved change order or claim is objective and verifiable.

This can lead to a situation where costs are recognized in one period and revenue is recognized when customer agreement is obtained or claim resolution occurs, which can be in subsequent periods.

2017 Consolidated Financial Statements | 6

NOA
The Company’s long term contracts typically allow its customers to unilaterally reduce or eliminate the scope of the work as contracted without cause. These long term contracts represent higher risk due to uncertainty of total contract value and estimated costs to complete; therefore, potentially impacting revenue recognition in future periods.
A contract is regarded as substantially completed when remaining costs and potential risks are insignificant in amount.
The Company recognizes revenue from equipment rental as performance requirements are achieved in accordance with the terms of the relevant agreement with the customer, either at a monthly fixed rate or on a usage basis dependent on the number of hours that the equipment is used. Revenue is recognized from the foregoing activity once persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, fees are fixed and determinable and collectability is reasonably assured.
d) Balance sheet classifications
A one-year time period is typically used as the basis for classifying current assets and liabilities. However, included in current assets and liabilities are amounts receivable and payable under construction contracts (principally holdbacks) that may extend beyond one year.
e) Cash
Cash includes cash on hand and bank balances net of outstanding cheques.
f) Accounts receivable and unbilled revenue
Accounts receivable are primarily comprised of amounts billed to clients for services already provided, but which have not yet been collected. Unbilled revenue represents revenue recognized from work performed in advance of amounts billed to clients.
g) Billings in excess of costs incurred and estimated earnings on uncompleted contracts
Billings in excess of costs incurred and estimated earnings on uncompleted contracts represent amounts invoiced in excess of revenue recognized.
h) Allowance for doubtful accounts
The Company evaluates the probability of collection of accounts receivable and records an allowance for doubtful accounts, which reduces accounts receivable to the amount management reasonably believes will be collected. In determining the amount of the allowance, the following factors are considered: the length of time the receivable has been outstanding, specific knowledge of each customer’s financial condition and historical experience.
i) Inventories
Inventories are carried at the lower of cost and net realizable value, and consist primarily of spare tires, tracks, track frames, fuel and lubricants. Cost is determined using the weighted average method.
j) Property, plant and equipment
Property, plant and equipment are recorded at cost. Major components of heavy construction equipment in use such as engines and drive trains are recorded separately. Equipment under capital lease is recorded at the present value of minimum lease payments at the inception of the lease. Depreciation is not recorded until an asset is available for use. Depreciation is calculated based on the cost, net of the estimated residual value, over the estimated useful life of the assets on the following bases and rates:

Assets |  | Basis |  | Rate
Heavy equipment |  | Units of production |  | 5,000 - 70,000 hours
Major component parts in use |  | Units of production |  | 1,000 - 36,000 hours
Other equipment |  | Straight-line |  | 5 – 10 years
Licensed motor vehicles |  | Straight-line |  | 5 – 10 years
Office and computer equipment |  | Straight-line |  | 4 years
Buildings |  | Straight-line |  | 10 – 25 years
Leasehold improvements |  | Straight-line |  | Over shorter of estimated useful life and lease term

The costs for periodic repairs and maintenance are expensed to the extent the expenditures serve only to restore the assets to their normal operating condition without enhancing their service potential or extending their useful lives.
k) Intangible assets
Intangible assets include capitalized computer software and development costs, which are being amortized on a straight-line basis over a maximum period of four years.
The Company expenses or capitalizes costs associated with the development of internal-use software as follows:

• | Preliminary project stage: Both internal and external costs incurred during this stage are expensed as incurred.

• | Application development stage: Both internal and external costs incurred to purchase and develop computer software are capitalized after the preliminary project stage is completed and management authorizes the computer software project. However, training costs and the costs incurred for the process of data conversion from the old system to the new system, which includes purging or cleansing of existing data, reconciliation or balancing of old data to the converted data in the new system, are expensed as incurred.

• | Post implementation/operation stage: All training costs and maintenance costs incurred during this stage are expensed as incurred.

Costs of upgrades and enhancements are capitalized if the expenditures will result in added functionality to the software.
l) Impairment of long-lived assets
Long-lived assets or asset groups held and used including property, plant and equipment and identifiable intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of an asset or group of assets is less than its carrying amount, it is considered to be impaired. The Company measures the impairment loss as the amount by which the carrying amount of the asset or group of assets exceeds its fair value, which is charged to depreciation or amortization expense. In determining whether an impairment exists, the Company makes assumptions about the future cash flows expected from the use of its long-lived assets, such as: applicable industry performance and prospects; general business and economic conditions that prevail and are expected to prevail; expected growth; maintaining its customer base; and, achieving cost reductions. There can be no assurance that expected future cash flows will be realized, or will be sufficient to recover the carrying amount of long-lived assets. Furthermore, the process of determining fair values is subjective and requires management to exercise judgment in making assumptions about future results, including revenue and cash flow projections and discount rates.
m) Assets held for sale
Long-lived assets are classified as held for sale when certain criteria are met, which include:

• | management, having the authority to approve the action, commits to a plan to sell the assets;

• | the assets are available for immediate sale in their present condition;

• | an active program to locate buyers and other actions to sell the assets have been initiated;

• | the sale of the assets is probable and their transfer is expected to qualify for recognition as a completed sale within one year;

• | the assets are being actively marketed at reasonable prices in relation to their fair value; and

• | it is unlikely that significant changes will be made to the plan to sell the assets or that the plan will be withdrawn.

A long-lived asset that is newly acquired and will be sold rather than held and used is classified as held for sale if the one year requirement is met and if the other requirements are expected to be met within a short period following the asset acquisition. Assets to be disposed of by sale are reported at the lower of their carrying amount or estimated fair value less costs to sell and are disclosed separately on the Consolidated Balance Sheets. These assets are not depreciated.
Equipment disposal decisions are made using an approach in which a target life is set for each type of equipment. The target life is based on the manufacturer’s recommendations and the Company’s past experience in the various operating environments. Once a piece of equipment reaches its target life it is evaluated to determine if disposal is warranted based on its expected operating cost and reliability in its current state. If the expected operating cost exceeds the target operating cost for the fleet or if the expected reliability is lower than the target reliability of the

2017 Consolidated Financial Statements | 8

NOA
fleet, the unit is considered for disposal. Expected operating costs and reliability are based on the past history of the unit and experience in the various operating environments. Once the Company has determined that the equipment will be disposed, and the criteria for assets held for sale are met, the unit is recorded in assets held for sale at the lower of depreciated cost or net realizable value.
n) Asset retirement obligations
Asset retirement obligations are legal obligations associated with the retirement of property, plant and equipment that result from their acquisition, lease, construction, development or normal operations. The Company recognizes its contractual obligations for the retirement of certain tangible long-lived assets. The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of a liability for an asset retirement obligation is the amount at which that liability could be settled in a current transaction between willing parties. In the absence of observable market transactions, the fair value of the liability is determined as the present value of expected cash flows. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset and then amortized using a systematic and rational method over its estimated useful life. In subsequent reporting periods, the liability is adjusted for the passage of time through an accretion charge and any changes in the amount or timing of the underlying future cash flows are recognized as an additional asset retirement cost.
o) Foreign currency translation
The functional currency of the Company and its subsidiaries is Canadian Dollars. Transactions denominated in foreign currencies are recorded at the rate of exchange on the transaction date. Monetary assets and liabilities, denominated in foreign currencies, are translated into Canadian Dollars at the rate of exchange prevailing at the balance sheet date. Foreign exchange gains and losses are included in the determination of earnings.
p) Fair value measurement
Fair value measurements are categorized using a valuation hierarchy for disclosure of the inputs used to measure fair value, which prioritizes the inputs into three broad levels. Fair values included in Level 1 are determined by reference to quoted prices in active markets for identical assets and liabilities. Fair values included in Level 2 include valuations using inputs based on observable market data, either directly or indirectly other than the quoted prices. Level 3 valuations are based on inputs that are not based on observable market data. The classification of a fair value within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
q) Derivative financial instruments
The Company has used derivative financial instruments to manage financial risks from fluctuations in exchange rates. Such instruments were only used for risk management purposes. The Company does not hold or issue derivative financial instruments for trading or speculative purposes.
r) Income taxes
The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. 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 from a change in tax rates is recognized in income in the period of enactment. A valuation allowance is recorded against any deferred tax asset if it is more likely than not that the asset will not be realized.
s) Tax positions
The Company recognizes the effect of income tax positions only if those positions are more likely than not (greater than 50%) of being sustained. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs. The Company accrues interest and penalties for uncertain tax positions in the period in which these uncertainties are identified. Interest and penalties are included in “General and administrative expenses” in the Consolidated Statements of Operations.
t) Stock-based compensation
The Company has a Share Option Plan which is described in note 21(b). The Company accounts for all stock-based compensation payments that are settled by the issuance of equity instruments at fair value. Compensation cost is measured using the Black-Scholes model at the grant date and is expensed on a straight-line basis over the

9 | 2017 Consolidated Financial Statements

NOA
award’s vesting period, with a corresponding increase to additional paid-in capital. Upon exercise of a stock option, share capital is recorded at the sum of proceeds received and the related amount of additional paid-in capital.
The Company has a Restricted Share Unit (“RSU”) Plan which is described in note 21(c). RSUs are generally granted effective July 1 of each fiscal year with respect to services to be provided in that fiscal year and the following two fiscal years. The RSUs generally vest at the end of the three-year term. The Company settles all RSUs issued after February 19, 2014 with common shares purchased on the open market through a trust arrangement ("equity classified RSUs"). The Company settled RSUs issued prior to February 19, 2014 with cash ("liability classified RSUs"). Compensation expense on liability classified RSUs was calculated based on the number of vested RSUs multiplied by the fair value of each RSU as determined by the volume weighted average trading price of the Company’s common shares for the thirty trading days immediately preceding the day on which the fair market value was to be determined. The Company recognized compensation cost over the three-year term of the liability classified RSU with any changes in fair value recognized in general and administrative expenses on the Consolidated Statements of Operations. At December 31, 2017, there were no unrecognized compensation costs related to non-vested share-based payment arrangements under the liability classified RSU plan. The Company recognizes compensation cost over the three-year term of the equity classified RSUs in the Consolidated Statement of Operations, with a corresponding increase to additional paid-in capital. When dividends are paid on common shares, additional dividend equivalent RSUs are granted to all RSU holders as of the dividend payment date. The number of additional RSUs to be granted is determined by multiplying the dividend payment per common share by the number of outstanding RSUs, divided by the fair market value of the Company's common shares on the dividend payment date. Such additional RSUs are granted subject to the same service criteria as the underlying RSUs.
The Company has a Performance Restricted Share Unit ("PSU") plan which is described in note 21(d). The PSUs vest at the end of a three-year term and are subject to the performance criteria approved by the Human Resources and Compensation Committee at the date of the grant. Such performance criterion includes the passage of time and is based upon the improvement of total shareholder return ("TSR") as compared to a defined company Canadian peer group. TSR is calculated using the fair market values of voting common shares at the grant date, the fair market value of voting common shares at the vesting date and the total dividends declared and paid throughout the vesting period. The grants are measured at fair value on the grant date using the Monte Carlo model. At the maturity date, the Human Resources and Compensation Committee will assess actual performance against the performance criteria and determine the number of PSUs that have been earned. The Company intends to settle all PSUs with common shares purchased on the open market through a trust arrangement. The Company recognizes compensation cost over the three-year term of the PSU in the Consolidated Statement of Operations, with a corresponding increase to additional paid-in capital.
The Company has a Deferred Stock Unit (“DSU”) Plan which is described in note 21(e). The DSU plan enables directors and executives to receive all or a portion of their annual fee or annual executive bonus compensation in the form of DSUs and are settled in cash. Compensation expense is calculated based on the number of DSUs multiplied by the fair market value of each DSU as determined by the volume weighted average trading price of the Company’s common shares for the thirty trading days immediately preceding the day on which the fair market value is to be determined, with any changes in fair value recognized in general and administrative expenses on the Consolidated Statements of Operations. Compensation costs related to DSUs are recognized in full upon the grant date as the units vest immediately. When dividends are paid on common shares, additional dividend equivalent DSUs are granted to all DSU holders as of the dividend payment date. The number of additional DSUs to be granted is determined by multiplying the dividend payment per common share by the number of outstanding DSUs, divided by the fair market value of the Company's common shares on the dividend payment date. Such additional DSUs are granted subject to the same service criteria as the underlying DSUs.
As stock-based compensation expense recognized in the Consolidated Statements of Earnings is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures, based on historical experience. Forfeitures are estimated at the time of grant and revised, in subsequent periods if actual forfeitures differ from those estimates.
u) Net income (loss) per share
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the year (see note 17(b)). Diluted net income (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of shares outstanding during the year, adjusted for dilutive share amounts. The diluted per share amounts are calculated using the treasury stock method and the if-converted method. The treasury stock method increases the diluted weighted average shares

2017 Consolidated Financial Statements | 10

NOA
outstanding to include additional shares from the assumed exercise of equity settled stock options, if dilutive. The number of additional shares determined using the treasury stock method is calculated by assuming outstanding in-the-money stock options were exercised and the proceeds from such exercises, including any unamortized stock-based compensation cost, were used to acquire shares of common stock at the average market price during the year. The if-converted method increases the diluted weighted average shares outstanding to include additional shares from the assumed conversion of convertible debentures, if dilutive. The number of additional shares is calculated by assuming the dilutive convertible shares would be outstanding for the entire period, or at the date of issuance, if later. If the convertible debentures are dilutive, the after tax interest expense related to the convertible debentures for the entire period, or from the date of issuance if later, is added back to the net income (loss).
v) Leases
Leases entered into by the Company in which substantially all the benefits and risks of ownership are transferred to the Company are recorded as obligations under capital leases and under the corresponding category of property, plant and equipment. Obligations under capital leases reflect the present value of future lease payments, discounted at an appropriate interest rate, and are reduced by rental payments net of imputed interest. All other leases are classified as operating leases and leasing costs, including any rent holidays, leasehold incentives, and rent concessions, are amortized on a straight-line basis over the lease term.
Certain operating lease and rental agreements provide a maximum operating hour usage limit, above which the Company will be required to pay for the over limit usage as a contingent rent expense. These contingent expenses are recognized when the likelihood of exceeding the usage limit is considered probable and are due at the end of the lease term or rental period. The contingent rental expenses are included in “Equipment costs” in the Consolidated Statements of Operations.
w) Deferred financing costs
Underwriting, legal and other direct costs incurred in connection with the issuance of debt are presented as deferred financing costs. Deferred financing costs related to the issuance of the Convertible Debentures and the Previous Term Loans are included within liabilities on the Consolidated Balance Sheets and are amortized using the effective interest rate method over the term to maturity. Deferred financing costs related to the Revolver, and the Previous Revolver, are included within other assets on the Consolidated Balance Sheets and are amortized ratably over the term of the Credit Facility.
3. Accounting pronouncements recently adopted
a) Inventory
In July 2015, the Financial Accounting Standard Board ("FASB") issued Accounting Standard Update ("ASU") No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This accounting standard simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value from the lower of cost or market. This standard was adopted January 1, 2017 and the adoption did not have a material effect on the Company's consolidated financial statements.
b) Accounting Changes and Error Corrections
In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error corrections (Topic 250) and investments - Equity Method and Joint ventures (Topic 323) to enhance disclosures of new accounting standards, including a comparison to current accounting policies, and the progress status of implementation.This ASU applies to ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606); ASU No. 2016-02, Leases (Topic 842); and ASU 2016-03, Financial Instruments - Credit Losses (Topic 326). This standard was effective upon issuance and has been adopted by the Company.
4. Recent accounting pronouncements not yet adopted
a) Revenue from Contracts with Customers
In May 2014, the FASB issued ASC Topic 606, Revenue from Contracts with Customers, and subsequently issued several related ASUs which provide guidance that requires an entity to recognize revenue in accordance with a five step model. Topic 606 will replace nearly all existing US GAAP revenue guidance, including industry-specific requirements, with a single comprehensive standard and significantly expands the disclosure requirements for revenue arrangements. The model is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the total consideration to which the entity expects to be entitled, during the term of the contract, in exchange for those goods or services. The new standard, as amended, will be effective for the Company for interim and annual reporting periods commencing January 1, 2018.

11 | 2017 Consolidated Financial Statements

NOA
The standard allows the use of either a full retrospective approach with restatement of all prior periods presented, or a modified retrospective approach with a cumulative effect adjustment as of the date of initial application. The Company will adopt Topic 606 applying the modified retrospective approach to only contracts that were not completed contracts with the cumulative effect adjustment recorded to equity at January 1, 2018, subject to the allowable and elected practical expedient.
To date, the Company has assessed Topic 606 to identify accounting and disclosure gaps specific to the work performed by the Company, determined the new data requirements to identify information gaps, and systems and/or reports that require modifications, considered changes to chart of accounts to facilitate entering and tracking of required information, and mapped processes to determine required changes to policies, procedures, and controls.
The Company currently recognizes revenue on its construction contracts, which comprise the majority of overall revenue, as costs are incurred on undefined scope work and using a percentage-of-completion method for defined scope work. With respect to the undefined scope work, revenue recognition under the new standard will be materially the same as revenue recognition under the existing standard for undefined scope work. With respect to revenue recognized using a percentage-of-completion method for defined scope work, the Company uses the input method of costs incurred to measure progress towards completion as that most accurately depicts the Company’s performance. As this method is permitted under the new standard, the Company will continue in its application. However, there are certain areas where the Company is quantifying the impact, if any, on its contracts that are in progress for the cumulative effect adjustment as the timing of revenue recognition may change under the new standard. These areas include identifying separate performance obligations, assessing contract modification including claims revenue, estimating variable consideration including contract incentives and penalties, and considering treatment of contract costs to obtain and fulfill a contract. There will be no changes to the treatment of cash flows and cash will continue to be collected in line with contractual terms.
The Company expects to add significant disclosures based on the prescribed requirements. These new disclosures will include information regarding the significant judgments used in evaluating when and how revenues are recognized and information related to contract assets and deferred revenues. In addition, the new guidance requires that the Company’s revenue recognition policy disclosure includes additional detail regarding the various performance obligations and the nature, amount, timing and estimates of revenues and cash flows generated from contracts with customers. The Company is drafting the relevant disclosures to reflect the requirements of the new standard and expects to apply the practical expedient to not disclose any information about remaining performance obligations that have original expected durations of one year or less.
b) Leases
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) to supersede the current leases accounting standard (Topic 840). The main difference between the new standard and the current standard is the requirement that lessees recognize a lease liability and a right-of-use asset for leases currently classified as operating leases with a term longer than twelve months. Lessor accounting remains largely unchanged. Additionally, the standard requires that for a sale to occur in a sale-leaseback transaction, the transfer of assets must meet the requirements for a sale under Topic 606.
The standard requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available.
The Company continues to evaluate the impact of adopting the standard on its financial statements and disclosure through its change management plan which guides the adoption of the standard. The Company has compiled an inventory of all leases and is analyzing individual contracts or groups of contracts to identify any significant differences and the impact on lease transactions as a result of adopting the new standard. Through this process, the Company will also quantify the impact, on in-scope prior period transactions as well as assess the Company’s policies, practices, procedures, controls, and systems for changes necessary to process and compile the information to meet the requirements of the new standard. The new standard will be effective for interim and annual reporting periods commencing January 1, 2019, with early adoption permitted.

c) Statement of Cash Flows
In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230: Classification of Certain Cash Receipts and Cash Payments). This accounting standard eliminates the diversity in practice related to the classification of certain cash receipts and payments for debt prepayments or extinguishment costs, the maturing of a zero coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization. This ASU will be effective commencing January 1, 2018, with early adoption permitted. The Company is assessing the impact the adoption of this standard will have on its consolidated financial statements.
d) Stock-Based Compensation
In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718: Scope of Modification Accounting). This accounting standard update clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This ASU will be effective commencing January 1, 2018, with early adoption permitted. The Company is assessing the impact the adoption of this standard will have on its consolidated financial statements.

8. Assets held for sale
At December 31, 2017, the Company classified $5,642 of property, plant and equipment as “Assets held for sale” on the Consolidated Balance Sheets (2016 - $247). During the year ended December 31, 2017, impairment of assets held for sale amounting to $1,621 has been included in depreciation expense in the Consolidated Statements of Operations (2016 – $1,556). The write-down is the amount by which the carrying value of the related assets exceeded their fair value less costs to sell. The gain on disposal of assets held for sale was $166 for the year ended December 31, 2017 (2016 – gain of $374). The estimated fair value of the property was based on the proceeds expected on the close of the sale.

On August 1, 2017, the Company entered into a new Credit Facility Agreement (the "Credit Facility") with a banking syndicate led by National Bank of Canada, replacing the Sixth Amended and Restated Credit Agreement (the “Previous Credit Facility”), which included a revolving loan (the "Previous Revolver") and a term loan (the "Previous Term Loan"). The Credit Facility matures on August 1, 2020. The Credit Facility is comprised solely of a revolving loan (the “Revolver”) which allows borrowing of up to $140.0 million with an ability to increase the maximum borrowings by an additional $25.0 million, subject to certain conditions. Unlike the Previous Credit Facility, the Credit Facility borrowing is not contingent upon the value of the borrowing base. The Credit Facility permits additional capital lease debt to a limit of $100.0 million. This facility matures on August 1, 2020, with an option to extend on an annual basis.
As at December 31, 2017, there was $0.8 million in issued letters of credit under the Credit Facility and the unused borrowing availability was $107.2 million. The Previous Credit Facility was composed of a $70.0 million Previous Revolver and a $30.0 million Previous Term Loan, contingent on a borrowing base which was determined by the value of accounts receivable, inventory, unbilled revenue and property, plant and equipment. As at December 31, 2016, under the Previous Revolver, there was $0.8 million in issued letters of credit and the borrowing base allowed for a maximum draw of $92.1 million. At December 31, 2016, the Company’s unused borrowing availability under the Previous Revolver was $58.2 million, which was limited by the borrowing base to $51.7 million.
The Credit Facility has two financial covenants that must be tested quarterly on a trailing four quarter basis. The first covenant is the senior leverage ratio ("Senior Leverage Ratio") is defined as senior debt ("Senior Debt" is defined as interest bearing debt excluding Convertible Debentures) as compared to earnings before interest, taxes, depreciation, and amortization, excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial instruments, cash and non-cash stock-based compensation expense, gain or loss on disposal of property, plant and equipment, gain or loss on disposal of assets held for sale and certain other non-cash items included in the calculation of net income ("Adjusted EBITDA"). The second covenant is the fixed charge coverage ratio ("Fixed Charge Coverage Ratio") which is defined as Adjusted EBITDA less cash taxes to Fixed Charges. Fixed charges ("Fixed Charges") is defined as cash interest, scheduled payments on debt, unfunded cash distributions by the Company and unfunded capital expenditures. The Senior Leverage Ratio is to be maintained at less than 3.0:1 and the Fixed Charge Coverage Ratio is to be maintained at a ratio greater than 1.15:1. In the event the Company enters into an acquisition, the maximum allowable Senior Leverage Ratio would

increase to 3.5:1 for four quarters following the acquisition. As at December 31, 2017, the Company was in compliance with financial covenants.
The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, Canadian bankers’ acceptance rate or London interbank offered rate (LIBOR) (all such terms as used or defined in the Credit Facility), plus applicable margins. The Company is also subject to non-refundable standby fees, 0.35% to 0.65% depending on the Company's Senior Leverage Ratio, based on the undrawn portion of the Credit Facility. The Credit Facility is secured by a first priority lien on all of the Company's existing and after-acquired property.
During the year ended December 31,2017, financing fees of $840 were incurred in connection with the Revolver under the New Credit Facility Agreement (2016 – $30 in connection with modifications to the Previous Revolver under the Previous Credit Facility Revolver). These amounts are included within deferred financing costs within other assets (note 10(c)). During the year ended December 31, 2017, the Company recorded a write-off of $329 in deferred financing fees associated with the extinguishment of the Previous Credit Facility.
c) Series 1 Debentures
During the year ended December 31, 2016, the Company redeemed $19.9 million of the Series 1 Debentures, plus accrued and unpaid interest which brought the outstanding Series 1 Debentures balance to $nil. Upon the elimination of the Series 1 Debentures, the Company a recorded a $0.6 million write-off of deferred financing costs.
d) Convertible Debentures
On March 15, 2017, the Company issued $40.0 million in aggregate principal amount of 5.50% convertible unsecured subordinated debentures (the "Convertible Debentures") which mature on March 31, 2024. The Company pays interest at an annual rate of 5.50%, payable semi-annually on March 31 and September 30 of each year, commencing September 30, 2017.
The Convertible Debentures may be converted into common shares of the Company at the option of the holder at a conversion price of $10.85 per common share, which is equivalent to approximately 92.1659 common shares per $1,000 principal amount of notes.
The Convertible Debentures are not redeemable prior to March 31, 2020, except under certain conditions after a change in control has occurred. The Convertible Debentures are redeemable at the option of the Company, in whole or in part, at any time on or after March 31, 2020 at a redemption price equal to the principal amount provided that the market price of the common shares is at least 125% of the conversion price; and on or after March 31, 2022 at a redemption price equal to the principal amount, plus accrued and unpaid interest accrued to the redemption date. In each case, the Company must pay accrued and unpaid interest on the debentures redeemed to the applicable redemption date.
If a change in control occurs, the Company is required to offer to purchase all of the Convertible Debentures at a price equal to 101% of the principal amount plus accrued and unpaid interest to the date of purchase.
During the year ended December 31, 2017, financing costs of $2,142 were incurred in connection with the issuance of the Convertible Debentures. This amount is included within deferred financing fees as a direct reduction to the carrying amount of long term debt (note 13(e)).

15. Financial instruments and risk management
a) Fair value measurements
In determining the fair value of financial instruments, the Company uses a variety of methods and assumptions that are based on market conditions and risks existing on each reporting date. Standard market conventions and techniques, such as discounted cash flow analysis and option pricing models, are used to determine the fair value of the Company’s financial instruments, including derivatives. All methods of fair value measurement result in a general approximation of value and such value may never actually be realized.
The fair values of the Company’s cash, accounts receivable, unbilled revenue, loan to partnership, accounts payable, accrued liabilities and billings in excess approximate their carrying amounts due to the relatively short periods to maturity for the instruments.
The fair values of amounts due under the Credit Facility are based on management estimates which are determined by discounting cash flows required under the instruments at the interest rate currently estimated to be available for instruments with similar terms. Based on these estimates, and by using the outstanding balance of $32.0 million at December 31, 2017 and $39.6 million at December 31, 2016 (note 13(b)), the fair value of amounts due under the Credit Facility are not significantly different than the carrying value.
Financial instruments with carrying amounts that differ from their fair values are as follows:

|  |  |  | December 31, 2017 |  |  | December 31, 2016 |
|  | Fair Value Hierarchy Level |  | Carrying Amount |  |  | Fair Value |  |  | Carrying Amount |  |  | Fair Value |
Capital lease obligations (i) |  | Level 2 |  | $ | 66,969 |  |  | $ | 61,872 |  |  | $ | 61,400 |  |  | $ | 57,741 |
Convertible Debentures (ii) |  | Level 1 |  | 40,000 |  |  | 38,700 |  |  | — |  |  | — |

(i) | The fair values of amounts due under capital leases are based on management estimates which are determined by discounting cash flows required under the instruments at the interest rates currently estimated to be available for instruments with similar terms.

(ii) | The fair value of the Convertible Debentures is based upon the period end closing market price.

Non-financial assets measured at estimated fair market value on a non-recurring basis as at December 31, 2017 and 2016 in the financial statements are summarized below:

|  | December 31, 2017 |  |  | December 31, 2016 |
|  | Carrying Amount |  |  | Change in Fair Value |  |  | Carrying Amount |  |  | Change in Fair Value |
Assets held for sale |  | $ | 5,642 |  |  | $ | (72 | ) |  | $ | 247 |  |  | $ | (1,556 | )

Assets held for sale are reported at the lower of their carrying amount or estimated fair market value less cost to sell. The estimated fair market value less cost to sell of equipment assets held for sale (note 8) is determined internally by analyzing recent auction prices for equipment with similar specifications and hours used, the residual value of the asset and the useful life of the asset. The estimated fair market value of the equipment assets held for sale are classified under Level 3 of the fair value hierarchy.

b) Risk management
The Company is exposed to market and credit risks associated with its financial instruments. The Company will from time to time use various financial instruments to reduce market risk exposures from changes in foreign currency exchange rates and interest rates. The Company does not hold or use any derivative instruments for trading or speculative purposes.
Overall, the Company’s Board of Directors has responsibility for the establishment and approval of the Company’s risk management policies. Management performs a risk assessment on a continual basis to help ensure that all significant risks related to the Company and its operations have been reviewed and assessed to reflect changes in market conditions and the Company’s operating activities.
c) Market risk
Market risk is the risk that the future revenue or operating expense related cash flows, the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices such as foreign currency exchange rates and interest rates. The level of market risk to which the Company is exposed at any point in time varies depending on market conditions, expectations of future price or market rate movements and composition of the Company’s financial assets and liabilities held, non-trading physical assets and contract portfolios.
To manage the exposure related to changes in market risk, the Company has used various risk management techniques including the use of derivative instruments. Such instruments may be used to establish a fixed price for a commodity, an interest bearing obligation or a cash flow denominated in a foreign currency.
The sensitivities provided below are hypothetical and should not be considered to be predictive of future performance or indicative of earnings on these contracts.
i) Foreign exchange risk
The Company regularly transacts in foreign currencies when purchasing equipment and spare parts as well as certain general and administrative goods and services. These exposures are generally of a short-term nature and the impact of changes in exchange rates has not been significant in the past. The Company may fix its exposure in either the Canadian Dollar or the US Dollar for these short term transactions, if material.
ii) Interest rate risk
The Company is exposed to interest rate risk from the possibility that changes in interest rates will affect future cash flows or the fair values of its financial instruments. Interest expense on borrowings with floating interest rates, including the Company’s Credit Facility, varies as market interest rates change. At December 31, 2017, the Company held $32.0 million of floating rate debt pertaining to its Credit Facility (December 31, 2016 – $39.6 million). As at December 31, 2017, holding all other variables constant, a 100 basis point change to interest rates on floating rate debt will result in $0.3 million corresponding change in annual interest expense. This assumes that the amount of floating rate debt remains unchanged from that which was held at December 31, 2017.
The fair value of financial instruments with fixed interest rates fluctuate with changes in market interest rates. However, these fluctuations do not affect earnings, as the Company’s debt is carried at amortized cost and the carrying value does not change as interest rates change.
The Company manages its interest rate risk exposure by using a mix of fixed and variable rate debt and may use derivative instruments to achieve the desired proportion of variable to fixed-rate debt.
d) Credit risk
Credit risk is the risk that financial loss to the Company may be incurred if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company manages the credit risk associated with its cash by holding its funds with what it believes to be reputable financial institutions. The Company is also exposed to credit risk through its accounts receivable and unbilled revenue. Credit risk for trade and other accounts receivables and unbilled revenue are managed through established credit monitoring activities.

The Company has a concentration of customers in the oil and gas sector. The following customers accounted for 10% or more of total revenues:

Year ended December 31, |  | 2017 |  |  | 2016 |
Customer A |  | 44 | % |  | 47 | %
Customer B |  | 26 | % |  | 25 | %
Customer C |  | 17 | % |  | 21 | %

The concentration risk is mitigated primarily by the customers being large investment grade organizations. The credit worthiness of new customers is subject to review by management through consideration of the type of customer and the size of the contract.
At December 31, 2017 and December 31, 2016, the following customers represented 10% or more of accounts receivable and unbilled revenue:

|  | December 31, 2017 |  |  | December 31, 2016 |
Customer 1 |  | 42 | % |  | 42 | %
Customer 2 |  | 20 | % |  | 22 | %
Customer 3 |  | 10 | % |  | 7 | %
Customer 4 |  | 10 | % |  | 13 | %
Customer 5 |  | 2 | % |  | 13 | %

The Company reviews its accounts receivable amounts regularly and amounts are written down to their expected realizable value when outstanding amounts are determined not to be fully collectible. This generally occurs when the customer has indicated an inability to pay, the Company is unable to communicate with the customer over an extended period of time, and other methods to obtain payment have not been successful. Bad debt expense is charged to project costs in the Consolidated Statements of Operations in the period that the account is determined to be doubtful. Estimates of the allowance for doubtful accounts are determined on a customer-by-customer evaluation of collectability at each reporting date taking into consideration the following factors: the length of time the receivable has been outstanding, specific knowledge of each customer’s financial condition and historical experience. The Company reviews its unbilled revenue regularly and assesses any amounts that are not billed within the next billing cycle to confirm collectability.
The Company’s maximum exposure to credit risk for accounts receivable and unbilled revenue is as follows:

|  | December 31, 2017 |  |  | December 31, 2016 |
Trade accounts receivables |  | $ | 45,716 |  |  | $ | 39,274 |
Other receivables |  | 1,512 |  |  | 806 |
Total accounts receivable |  | $ | 47,228 |  |  | $ | 40,080 |
Unbilled revenue |  | 21,572 |  |  | 15,965 |
Total |  | $ | 68,800 |  |  | $ | 56,045 |

Payment terms are per the negotiated customer contracts and generally range between net 15 days and net 60 days. As at December 31, 2017 and December 31, 2016, trade receivables are aged as follows:

|  | December 31, 2017 |  |  | December 31, 2016 |
Not past due |  | $ | 42,882 |  |  | $ | 34,263 |
Past due 1-30 days |  | 2,566 |  |  | 2,956 |

More than 61 days |  | 268 |  |  | 55 |
Total |  | $ | 45,716 |  |  | $ | 39,274 |

As at December 31, 2017, the Company has recorded an allowance for doubtful accounts of $nil (December 31, 2016 - $nil).
