2. SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

These consolidated financial statements (“Financial Statements”), including comparative figures, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

In these Financial Statements, unless otherwise indicated, all dollar amounts are expressed in United States (“U.S.”) dollars. DIRTT’s financial results are consolidated in Canadian dollars, the Company’s functional currency, and the Company has adopted the U.S. dollar as its reporting currency. All references to US$ or $ are to U.S. dollars and references to C$ are to Canadian dollars.

Principles of consolidation

The Financial Statements include the accounts of DIRTT and its subsidiaries. All intercompany balances, income and expenses, unrealized gains and losses and dividends resulting from intercompany transactions have been eliminated upon consolidation.

Basis of measurement

These Financial Statements have been prepared on the historical cost convention except for certain financial instruments and stock-based compensation that are measured at fair value, as explained in the accounting policies below. Historical cost is generally based on the fair value of the consideration given in exchange for assets.

Use of estimates

The preparation of the Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosure of contingent liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Such estimates primarily relate to unsettled transactions and events as of the date of the Financial Statements. Estimates are based on historical data and experience, as well as various other factors that management considers reasonable under the circumstances. Actual outcomes can differ from these estimates.

Significant estimates and assumptions made by management include:

•

Estimates of ability and timeliness of customer payments of trade receivables;

•

Estimates of useful lives of depreciable assets as well as the fair value of long-term assets and future cash flows used for impairment calculations;

•

Estimates of future taxable earnings used to assess the realizable value of deferred tax assets;

•

Tax interpretations, regulations and legislation in the various jurisdictions in which the Company and its subsidiaries operate;

•

Estimates of the fair value of stock awards, including whether the performance criteria will be met and measurement of the ultimate payout amount; and

•

Estimates of liabilities associated with the potential and amount of warranty, legal claims and other contingencies.

Segments

Management has determined that DIRTT has one operating segment. The Company’s chief executive officer, who is DIRTT’s chief operating decision maker, reviews financial information on a consolidated and aggregate basis, together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance.

Foreign currency translation

DIRTT Environmental Solutions Ltd. is a Canadian company and its functional currency is the Canadian dollar. DIRTT’s wholly owned subsidiary is domiciled in the United States and its functional currency is the U.S. dollar.

Assets and liabilities denominated in foreign currencies, other than those held through foreign subsidiaries, are translated into the transacting company’s functional currency at the year-end exchange rate for monetary items and at the historical exchange rates for non-monetary items. Foreign currency revenues and expenses are translated at the exchange rates in effect on the dates of the related transactions. Foreign exchange gains and losses, other than those arising from the translation of the Company’s net investments in foreign subsidiaries, are included in income.

The accounts of the Company’s U.S. dollar subsidiary is translated into Canadian dollars, and the Financial Statements are translated into U.S. dollars for financial statement presentation. Assets and liabilities are translated using year-end exchange rates, and revenues, expenses, gains and losses are translated using average monthly exchange rates. Foreign exchange gains and losses arising from the translation of the Company’s assets and liabilities are included in “comprehensive loss for the year”.

Cash and cash equivalents and restricted cash

Cash and cash equivalents include cash on hand held at banks and cash equivalents, which are defined as highly liquid investments with original maturities of three months or less. Restricted cash is a reserve account not available for immediate or general business use and is required when certain requirements are not met under the terms of the Company’s senior secured credit facility (as defined in Note 14).

Trade and other receivables, net of expected credit losses

Accounts receivable are recorded at the invoiced amount, do not require collateral and do not bear interest. The Company estimates its allowance for doubtful accounts using the current expected credit loss (“CECL”) methodology, which is designed to capture the Company’s current estimate of all expected credit losses.

Inventory

Inventory is comprised of raw materials and work in progress. The Company does not typically carry a significant amount of finished goods inventory. Inventory is valued at the lower of weighted average cost and net realizable value. Net realizable value is based on an item’s usability in the manufacturing of the Company’s products. The Company records an allowance for obsolescence when the net realizable value of inventory items declines below weighted average cost, net realizable value is determined based on current market prices for inventory less the estimated cost to sell. Work in progress is valued at an estimate of cost, including attributable overheads, based on stage of completion.

Fixed production overheads are allocated to inventory on the basis of normal capacity of the production facilities. In periods where production levels are abnormally low, unallocated overheads are separately recognized as an expense in the period in which they are incurred.

Leases

The Company categorizes leases at their inception as either operating or finance leases. Leases where the Company assumes substantially all of the rewards or ownership and leases where ownership is transferred at the end of the lease term, or by way of a

bargain purchase option, are classified as finance leases. Upon initial recognition, the leased asset is measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability, so as to achieve a constant rate of interest on the balance of the liability. Finance charges are recognized in the statement of operations.

The Company’s Leasing Facilities (as defined in Note 7) are accounted for as finance leases as ownership of the equipment is expected to return to the Company at the end of the lease term. These transactions are not accounted for as a sale of the underlying equipment as the Company continues to control the equipment.

For leases categorized as operating, the Company determines if an arrangement is a lease or contains a lease element at inception. The arrangement is a lease if it conveys the right to the Company to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Operating leases are separately disclosed as operating lease right-of-use (“ROU”) assets, with a corresponding lease liability split between current and long-term components on the balance sheet. Operating leases with an initial term of 12 months or less are not included on the balance sheet.

The Company recognizes lease expense for these leases on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term.

Property, plant and equipment

Property, plant and equipment are recorded at cost, including direct costs, attributable indirect costs and carrying costs, less accumulated depreciation and any accumulated impairment losses. Expenditures for repairs and maintenance are expensed as incurred, while renewals and betterments are capitalized.

Depreciation is charged to the consolidated statement of operations on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of the Company’s property, plant and equipment are as follows:


Building	25 years
Manufacturing equipment	10 years
Leasehold improvements	Over term of lease (1 to 10 years)
Office equipment	5 years
Tooling and prototypes	4 years
Computer equipment	3 years
Vehicles	3 years

When assets are disposed of or retired, the cost and accumulated depreciation and impairment losses are removed from the respective accounts and any resulting loss is reflected in operating expenses.

Capitalized software costs

The Company capitalizes costs related to internally developed software during the application development stage when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project, and (iii) it is probable that the project will be completed and performed as intended. Capitalized costs includes costs of personnel and related expenses for employees and third parties directly attributable to the projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Costs incurred for significant upgrades and enhancements are also capitalized. Costs related to preliminary project activities and post implementation activities, including training, maintenance and minor modifications or enhancements are expensed as incurred. Capitalized software costs are amortized on a straight-line basis over the estimated useful life of the developed asset, which is generally three to five years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of the assets.

Software development is considered internal-use as it is used to design and sell the DIRTT products and is not included in the end client’s product. Revenues received from Construction Partners for ICE Software are recognized as revenues as they are considered an element of the product sale. Any incidental third-party revenues received for the ICE Software are credited against capitalized software costs. The Company follows this accounting policy for cloud computing arrangements that are considered a service contract, however, these projects are capitalized to prepaids and other assets on the balance sheet and are expensed as an

operating cost, as opposed to amortization, over the expected term of the software service contract. The Company adopted this amendment on January 1, 2020 using the prospective transition approach and classified $0.7 million as other assets on the consolidated balance sheet for the year ended December 31, 2021.

Impairment of long-lived assets

Management evaluates the recoverability of the Company’s property, plant and equipment, capitalized software costs and ROU assets when events or changes in circumstances indicate a potential impairment exists. Events and changes in circumstances considered by the Company in determining whether the carrying value of long-lived assets may not be recoverable include, but are not limited to, significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, and changes in the Company’s business strategy. Impairment testing is performed at an asset level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (an “asset group”). In determining if impairment exists, the Company estimates the undiscounted cash flows to be generated from the use and ultimate disposition of the asset group. If impairment is indicated based on a comparison of the assets’ carrying values and the undiscounted cash flows, the impairment loss is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Convertible Debentures

The Company accounts for convertible debentures as liabilities. Embedded features included in the convertible debentures that require bifurcation are accounted for separately. Costs incurred directly related to the issuance of convertible debentures are presented as a direct deduction against the carrying amount of the convertible debentures and are amortized to interest expense using the effective interest method.

Income taxes

Income tax expense is comprised of current and deferred tax. Income tax is recognized in the consolidated statement of operations and comprehensive income (loss) except to the extent it relates to items recognized directly in equity.

Current tax

Current tax expense is based on the results for the year, adjusted for items that are not taxable or not deductible. Current tax is calculated using tax rates and laws that were enacted at the end of the reporting period. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. Provisions are established where appropriate on the basis of amounts expected to be paid to the tax authorities.

Deferred tax

Deferred tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated balance sheet. Deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates and laws that will be in effect when the differences are expected to reverse.

The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income in the period during which the change occurs.

When appropriate, the Company records a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, the Company considers whether it is more likely than not that all or some portion of the Company’s deferred tax assets will not be realized, based on management’s judgment using available evidence about future events.

At times, tax benefits claims may be challenged by a tax authority. Tax benefits are recognized only for tax positions that are more likely than not sustainable upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.

Revenue recognition

The Company accounts for revenue in accordance with topic 606, Revenue from Contracts with Customers, (“ASC 606”) and Subtopic 340-40, Other Assets and Deferred Costs – Contracts with Customers. Under ASC 606, an entity recognizes revenue in a manner that reflects the transfer of promised goods or services to customers in an amount which the entity expects to be entitled in exchange for those goods or services.

The Company recognizes revenue upon transfer of control of promised goods or services to customers at transaction price, an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. Transaction price is calculated as selling price net of variable consideration which may include estimates for sales incentives related to current period product revenue. Revenue is measured at the fair value of the consideration received or receivable, after discounts, rebates and sales taxes or income taxes and duties.

Product sales

The Company recognizes revenue upon transfer of control of products to the customer, which typically occurs upon shipment. The Company’s main performance obligation to customers is the delivery of products in accordance with purchase orders. Each purchase order defines the transaction price for the products purchased under the arrangement. Construction Partners typically sell DIRTT product to end clients and issue purchase orders to the Company to manufacture the product. Construction Partners utilize ICE licenses to sell DIRTT products, the ICE licenses sold to Construction Partners are not considered a separate performance obligation as they are not distinct, and ICE license revenue is recognized in conjunction with product sales. The Construction Partner ICE Software revenue is recognized over the license period.

The Company’s standard sales terms are Free On Board (“FOB”) shipping point, which comprise the majority of sales. The Company usually requires a 50% progress payment on receipt of certain orders, excluding certain government orders or in some special contractual situations. Customer deposits received are recognized as a liability on the balance sheet until revenue recognition criteria is met. At the point of shipment, the customer is generally required to pay the balance of the sales price within 30 days. The Company’s sales arrangements do not have any material financing components. In addition, the Company’s customer arrangements do not produce contract assets that are material to its consolidated financial statements.

The Company provides sales commissions to internal and external sales representatives which are earned in the period in which revenue is recognized.

The Company accounts for product transportation revenue and costs as fulfillment activities and present the associated costs in costs of goods sold in the period in which the Company sells its product.

Contracts containing multiple performance obligations

The Company offers certain arrangements whereby a customer can purchase products and installation together which are generally capable of being distinct and accounted for as separate performance obligations. Where multiple performance obligations exist, the Company determines revenue recognition by (1) identifying the contract with the customer, (2) identifying the performance obligation in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations based on the relative standalone selling prices, typically based on cost plus a reasonable margin, and (5) recognizing revenue as the performance obligations are satisfied.

Installation and other services

The Company provides installation and other services for certain customers as a distinct performance obligation. Revenue from installation services is recognized over time as the service is performed.

Principal vs Agent Considerations

The Company evaluates the presentation of revenue on a gross vs. net basis based on whether it acts as a principal by controlling the product or service sales to customers. In certain instances, the Company facilitates contracting of certain sales on behalf of Construction Partners. The Company records these revenues on a gross basis when the Company is obligated to fulfill the service and has the risk associated with service delivery. The Company records these revenues on a net basis when the Construction Partner has the obligation to fulfill the services and has the risk associated with service delivery.

Construction Partner rebates

Rebates to Construction Partners (“Partner Rebates”) are accrued for and recognized as a reduction of revenue at the date of the sale to the customer. Partner Rebates include amounts collected directly by the Company owed to Construction Partners in accordance with their Construction Partner agreements, being the difference between the price to the end customer and the Construction Partners’ price. Other sales discounts are deducted immediately from sales invoices.

Contract balances

Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records an unbilled receivable when revenue is recognized prior to invoicing. As the Company’s contracts are less than one year in duration, the Company has elected to apply the practical expedients to expense costs related to costs to obtain contracts and not disclose unfulfilled performance obligations. As deferred revenue and customer deposits are typically recognized during the year the Company does not account for financing elements.

Warranties

The Company provides a warranty on all products sold to its clients and Construction Partner’s clients. Warranties are not sold separately to customers. Provisions for the expected cost of warranty obligations are recognized based on an analysis of historical costs for warranty claims relative to current activity levels and adjusted for factors based on management’s assessment that increase or decrease the provision. Warranty provision is recognized in cost of goods sold. Warranty claims have historically not been material and do not constitute a separate performance obligation.

Stock-based compensation

The Company follows the fair value-based approach to account for options, share awards and restricted share units (“RSUs”). Compensation expense and an increase in “Additional paid-in capital” are recognized for options and RSUs over their vesting period based on their estimated fair values on the grant date, as determined using the Black-Scholes option pricing model for the majority of options and the market value of the Company’s common shares on the grant date for share awards and RSUs. Certain executive stock options and RSUs have performance conditions and are valued using a Monte Carlo model.

On exercise of stock options and RSUs, the recorded fair value of the option or RSU is removed from “Additional paid-in capital” and credited to “Share capital”. For options, any consideration paid by employees is credited to “Share capital” when the option is exercised. The Company’s stock options and RSUs are not shares of the Company and have no rights to vote, receive dividends, or any other rights as a shareholder of the Company.

Stock based compensation expense is also recognized for performance share units (“PSUs”) and deferred share units (“DSUs”) using the fair value method. Compensation expense is recognized over the vesting period and the corresponding amount is recorded as a liability on the balance sheet.

Technology and development expenditures

Technology and development expenses are comprised primarily of salaries and benefits associated with the Company’s product and software development personnel which do not qualify for capitalization. These costs are expensed as incurred and exclude certain information and technology costs used in operations which are classified as general and administrative costs.

Government subsidies

The Company accounts for government subsidies on an accrual basis when the conditions for eligibility are met. The Company has adopted an accounting policy to present government subsidies as other income. The nature, significant terms and conditions of government subsidies are disclosed in the financial statements. (Refer to Note 3 on adoption of Accounting Standards Update No. 2021-10,Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance,)

Earnings per share (“EPS”)

Basic earnings per share is calculated using the weighted average number of common shares outstanding during the year. Diluted earnings per share is calculated using the treasury stock method for determining the dilutive impact of stock options. The Company follows the “if converted” method for accounting for the impact of convertible debentures on earnings (loss) per share, whereby interest charges applicable to the convertible debentures are added to the numerator and the convertible debentures are assumed to have been converted at the beginning of the period (or time of issuance, if later), and the resulting common shares are added to the denominator.

Fair value of financial instruments

ASC 820, “Fair Value Measurements,” requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet, for which it is practicable to estimate fair value. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The Company’s fair value analysis is based on the degree to which the fair value is observable and grouped into categories accordingly:

•

Level 1 financial instruments are those which can be derived from quoted market prices (unadjusted) in active markets for similar financial assets or liabilities.

•

Level 2 financial instruments are those which can be derived from inputs that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices). Level 2 financial instruments include current and long-term debt. The carrying amounts of these instruments approximates fair value due to limited changes to interest rates and the Company’s credit rating since issuance.

•

Level 3 financial instruments are those derived from valuation techniques that include inputs for the financial asset or liability which are not based on observable market data (unobservable inputs). The Company does not have any Level 3 financial instruments.

The carrying amounts of cash and cash equivalents and restricted cash; trade and accrued receivables, other receivables; accounts payable and accrued liabilities; other liabilities; and customer deposits approximate fair value due to their short-term nature.
