The Company and going concern
The Company And Going Concern	1. The Company and going concern NXT Energy Solutions Inc. (the “Company” or “NXT”) is a publicly traded company based in Calgary, Alberta Canada. NXT’s proprietary Stress Field Detection (“SFD ® These consolidated financial statements of NXT have been prepared by management in accordance with generally accepted accounting principles of the United States of America (“US GAAP”). These consolidated financial statements reflect adjustments, all of which are normal recurring adjustments that are, in the opinion of management, necessary to reflect fairly the financial position and results of operations for the respective periods. These consolidated financial statements have been prepared on a going concern basis. The going concern basis of presentation assumes that NXT will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The events described in the following paragraphs highlight that there is substantial doubt about NXT’s ability to continue as a going concern within one year after the date that these consolidated financial statements have been issued. The Company’s current cash position is not expected to be sufficient to meet the Company’s obligations and planned operations for a year beyond the date that these consolidated financial statements have been issued. The Company has plans in place to reduce operating costs including payroll and other general and administrative costs and is evaluating alternatives to reduce other costs. If required, further financing options that may or may not be available to the Company include issuance of new equity, debentures or bank credit facilities. The need for any of these options will be dependent on the timing of securing new SFD ® NXT continues to develop its pipeline of opportunities to secure new revenue contracts. However, the Company’s longer-term success remains dependent upon its ability to convert these opportunities into successful contracts, to continue to attract new client projects, ultimately to expand the revenue base to a level sufficient to exceed fixed operating costs and generate consistent positive cash flow from operations. The occurrence and timing of these events cannot be predicted with sufficient certainty. The consolidated financial statements do not reflect adjustments that would be necessary if the going concern basis was not appropriate. If the going concern basis was not appropriate for these consolidated financial statements, then adjustments would be necessary in the carrying value of the assets and liabilities, the reported revenues and expenses and the balance sheet classifications used. These adjustments could be material. Covid-19 Pandemic As of the date of these consolidated financial statements the Covid-19 pandemic continues to be a risk to the operations of the Company. The Company has made provisions so employees can work safely in the office or if necessary from home, followed all Alberta Health Services and Health Canada recommendations, and implemented hygiene and physical distancing policies. Demand for our services and prospective revenues may become adversely impacted the longer the Covid-19 pandemic continues. The impact of the continuation of the Covid-19 pandemic may hamper our ability to deliver SFD ® The situation is dynamic and the ultimate duration and magnitude of the impact on the economy and the financial effect to the Company is not known at this time. Estimates and judgments made by management in the preparation of these consolidated financial statements are subject to a higher degree of measurement uncertainty during this volatile period. Use of Estimates and Judgements In preparing these consolidated financial statements, NXT is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgment in making these estimates and assumptions. In the opinion of management, these consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company’s significant accounting policies. The estimates and assumptions used are based upon management’s best estimate as at the date of the consolidated financial statements. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the period when determined. Actual results may differ from those estimates. Critical accounting estimates relate primarily to the use of the going concern assumption, estimated useful lives and the valuation of intellectual property, property and equipment and the measurement of stock-based compensation expense.

Significant accounting policies
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation These consolidated financial statements for the period ended December 31, 2021 have been prepared by management in accordance with US GAAP. Consolidation These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries (all of which are inactive). All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and short term Guaranteed Investment Certificates (“GIC’s”) with an original maturity less than 90 days from the date of acquisition. Short Term Investments Short term investments consist of short term GICs, with original maturity dates greater than 90 days and up to one year. Derivative Instruments Derivative instruments are recognized on the balance sheet at fair value with any changes in fair value between periods recognized in the determination of net income (loss) for the period. NXT does not apply hedge accounting to any of its derivatives. As at December 31, 2021 and 2020, NXT had no outstanding derivative instruments. Fair Value Measures For any balance sheet items recorded at fair value on a recurring basis or non-recurring basis, the Company is required to classify the fair value measure into one of three categories based on the fair value hierarchy noted below. In Level I, the fair value of assets and liabilities is determined by reference to quoted prices in active markets for identical assets and liabilities that the Company has the ability to assess at the measurement date. At December 31, 2021, the fair value of the restricted stock units (“RSU”) liability based on share price was determined using Level I inputs. In Level II, determination of the fair value of assets and liabilities is based on the extrapolation of inputs, other than quoted prices included within Level I, for which all significant inputs are observable directly or indirectly. Such inputs include published exchange rates, interest rates, yield curves and stock quotes from external data service providers. Transfers between Level I and Level II would occur when there is a change in market circumstances. In Level III, the fair value of assets and liabilities measured on a recurring basis is determined using a market approach based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities measured at fair value can fluctuate between Level II and Level III depending on the proportion of the value of the contract that extends beyond the time frame for which inputs are considered to be observable. As contracts near maturity and observable market data becomes available, the contracts are transferred out of Level III and into Level II. The determination of the fair value of the acquisition of the Intellectual property (Note 9) was determined using Level III inputs. Measurement of credit losses on financial instruments The impairment model of financial instruments is based on expected losses rather than incurred losses. In making the assessment of expected losses, the Company considers the following factors: historically realized bad debts; a counterparty’s present financial condition and whether a counterparty has breached certain contracts; the probability that a counterparty will enter bankruptcy; changes in economic conditions that correlate to increased levels of default and term to maturity of the specific receivable. These expected credit losses are recognized as an allowance rather than as a direct write-down of the amortized cost basis. Deposits Deposits consist of security payments made to lessors for the Company’s office and aircraft lease. They are classified as long term if the lease end date is greater than one year. Property and Equipment Property and equipment is recorded at cost, less accumulated amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods: Computer hardware (including survey equipment) 30% declining balance Aircraft equipment 10% declining balance Furniture and other equipment 20% declining balance Leasehold improvements 10% declining balance Intellectual Property Intellectual property acquired is recorded at cost, less accumulated amortization, which is recorded over the estimated minimum useful life of the assets. The Company incurs periodic costs that are expensed when incurred to file patents and to maintain them. Impairment of Long-Lived Assets The Company reviews long-lived assets, which includes property, equipment and intellectual property for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company considers both internal and external factors when assessing for potential indicators of impairment, and with respect to intellectual property, the Company’s assessment includes consideration of historical and forecasted SFD ® ® When indicators of impairment exist, the Company first compares the total of the estimated undiscounted future cash flows or the estimated sale price to the carrying value of an asset. If the carrying value exceeds these amounts, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the asset. Research and Development Expenditure Research and development (“R&D”) expenditures incurred to develop, improve and test the SFD ® Foreign Currency Translation The Company’s functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in effect at the end of the applicable period. Non-monetary assets and liabilities are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the period. Income Taxes NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized. The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized. Stock Based Compensation NXT follows the fair value method of accounting for stock options, restricted stock units, deferred stock units, and the employee share purchase plan (the “Share Compensation Plans”) that are granted to acquire common shares under NXT’s Share Compensation Plans. For equity-settled stock-based compensation awards, fair values are determined at the grant date and the expense, net of estimated forfeitures, is recognized over the requisite service period with a corresponding increase recorded in contributed capital. An adjustment is made to compensation for any differences between the estimated forfeitures and the actual forfeitures. For cash-settled stock-based compensation awards, fair values, based on observable prices, are determined at each reporting date and periodic changes are recognized as compensation costs, with a corresponding change to liabilities. Upon exercise or realization of the equity-settled Share Compensation Plans, the consideration received by NXT, and the related amount which previously recorded in contributed capital, is recognized as an increase in the recorded value of the common shares of the Company. Net Income (Loss) Per Share Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period. Shares issued during the period are weighted for the portion of the period that the shares were outstanding. Diluted income per share, in periods when NXT has net income, is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and restricted stock units. The incremental number of shares added under the treasury stock method assumes that outstanding stock options and restricted stock units that are exercisable at exercise prices below the Company’s average market price (i.e. they were “in-the-money”) for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company’s shares for the applicable fiscal period. No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case where there is a net loss for the period). Revenue SFD ® Surveys The performance obligation for NXT in SFD ® ® ® The Company uses direct survey costs as the input measure to recognize revenue in any fiscal period. The percentage of direct survey costs incurred to date over the total expected survey costs to be incurred, provides an appropriate measure of the stage of the performance obligation being satisfied over time. SFD ® Data Sales The performance obligation for NXT in SFD ® ® Leases The Company determines if an arrangement is an operating or finance lease, as defined under U.S. GAAP, at inception. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. These leases are included in right-of-use (“ROU”) assets and lease obligations in the Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease obligations represent the obligation to make lease payments arising from such leases. Lease obligations are recognized at the lease commencement date based on the present value of remaining lease payments over the lease term, taking into consideration conditions such as incentives and termination penalties, as appropriate. A corresponding ROU asset is recognized at the amount of the lease obligation, adjusted for payments made prior to lease commencement or initial direct costs, if any. When calculating the present value, the Company uses the rate implicit in the lease, or uses its incremental borrowing rate for a similar term and risk profile based on the information available at the commencement date. The Company’s lease terms may have options to extend or terminate the lease which are included in the calculation of lease obligations when it is reasonably certain that it will exercise those options. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Office and equipment lease expenses are included within General and administrative expenses; the aircraft lease cost is included within SFD ® Lease agreements can contain both lease and non-lease components, which are accounted for separately. During 2021 the Company determined that the amounts previously recorded for the Aircraft lease were calculated incorrectly and the United States Dollar denominated lease liability had not been re-measured to Canadian Dollars each reporting period as required. The result of these corrections are to reduce the value of both the Right of use assets and Lease obligations, with changes to related income statement. The Company has determined that the effect of these adjustments are not material. The Company has recorded the adjustments in the related accounts in the comparative periods in these financial statements. On the balance sheet and income statement, the specific accounts affected are Deposits, Right of use assets, Current portion of lease obligations, Long-term lease obligations, Deficit, SFD ® Balance Sheet December 31, 2020 As previously reported Adjustments Adjusted Deposits $ 526,560 $ (100,730 ) $ 425,830 Right of use assets 2,415,430 (423,658 ) 1,991,772 Current portion of lease obligations (773,465 ) 85,474 (687,991 ) Long-term portion of lease obligations (1,896,277 ) 494,430 (1,401,847 ) Deficit 83,934,230 (55,516 ) 83,878,714 Income Statement For the year ended December 31, 2020 As previously reported Adjustments Adjusted SFD ® $ 1,091,587 $ 19,483 $ 1,111,070 Interest (income) expense (11,535 ) (2,527 ) (14,062 ) Foreign exchange loss (gain) (76,029 ) 11,597 (64,432 ) Net loss (5,999,675 ) (28,553 ) (6,028,228 ) Income Statement For the year ended December 31, 2019 As previously reported Adjustments Adjusted SFD ® $ 2,611,086 $ 41,969 $ 2,653,055 Interest (income) expense (20,684 ) (8,275 ) (28,959 ) Foreign exchange loss (gain) 233,231 (55,495 ) 177,736 Net income 3,772,908 21,801 3,794,709 Deficit 77,934,555 (84,069 ) 77,850,486 Accounting for the above adjustments, the adoption of Topic 842 resulted in the initial recognition of right-of-use assets of approximately $3.2 million, current lease liabilities of approximately $0.7 million, and non-current lease liabilities of approximately $2.8 million as at January 1, 2019. Before the above retrospective adjustments, at January 1, 2019, the Company recorded the initial recognition of right-of-use assets of approximately $3.5 million, current lease liabilities of approximately $0.7 million, and non-current lease liabilities of approximately $3.4 million. The disclosures in notes 5, 6, 8, 13, 17, 19 and 23 have also been revised. Consolidated Statement of Cash Flows In the preparation of the annual financial statements as at and for the year ended December 31, 2021, the Company has determined that certain amounts previously recorded in the 2019 and 2020 consolidated statements of cash flows were not correctly calculated to properly reflect payments on the financial liability, lease obligation payments and accretion, and application of exchange rates to calculate unrealized foreign exchange (gain) loss including the effect of foreign exchange on changes on cash and cash equivalents. The adjustments to correct the respective financial statement line items are not material and did not change the Cash, SFD® related revenues, or Net income (loss) accounts or basic and diluted loss per share. The Company has recorded the adjustments in the related line items in each of the comparative periods.

Income tax expense
Income Tax Expense	19. Income Tax Expense NXT periodically earns revenues while operating outside of Canada in foreign jurisdictions. Payments made to NXT for services rendered to clients and branch offices in certain countries may be subject to foreign income and withholding taxes. Such taxes incurred are only recoverable in certain limited circumstances, including potential utilization in Canada as a foreign tax credit, or against future taxable earnings from the foreign jurisdictions. Income tax expense is different from the expected amount that would be computed by applying the statutory Canadian federal and provincial income tax rates to NXT’s income (loss) before income taxes as follows: For the years ended December 31, 2021 2020 2019 (Adjusted – Note 2) (Adjusted – Note 2) Net loss before income taxes $ (3,123,799 ) $ (6,028,228 ) $ 3,794,709 Canadian statutory income tax rate 23.0 % 24.0 % 26.5 % Income tax (recovery) at statutory income tax rate (718,474 ) (1,446,775 ) 1,005,598 Effect of non- deductible expenses and other items: Stock-based compensation and other expenses 67,948 44,225 11,609 Change in statutory tax rates (92,850 ) (131,242 ) 918,821 Foreign exchange adjustments 662 29,910 82,433 Other (Expired losses) 1,206,056 258,091 43,592 Change in valuation allowance 463,342 (1,245,791 ) 2,062,053 Income tax expense (recovery) (463,342 ) 1,245,791 (2,062,053 ) Effective July 1, 2020, the Province of Alberta decreased its corporate tax rate from 10% to 8%.

Financial instruments
Financial Instruments	20. Financial instruments a) Non-derivative financial instruments: The Company’s non-derivative financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, deposits, accounts payables and accrued liabilities, long-term debt and lease obligations. The carrying value of these financial instruments, excluding leases, approximates their fair values due to their short terms to maturity. Credit Risk Credit risk arises from the potential that the Company may incur a loss if counterparty to a financial instrument fails to meet its obligation in accordance with agreed terms. The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The carrying value of cash and cash equivalents, short-term investments, and accounts receivable reflects management’s assessment of credit risk. At December 31, 2021, cash and cash equivalents and short-term investments included balances in bank accounts, term deposits and guaranteed investment certificates, placed with financial institutions with investment grade credit ratings. The majority of the Company’s accounts receivable relate to sales to one customer in the African region and is exposed to foreign country credit risks. The Company manages this credit risk by requiring advance payments before entering into certain contract milestones and when possible accounts receivable insurance. Foreign Exchange Risk The Company is exposed to foreign exchange risk in relation to its holding of significant US$ balances in cash and cash equivalents, short-term investments, accounts receivable, deposits, accounts payables, accrued liabilities, and lease obligations, and entering into United States dollar revenue contracts. The Company does not currently enter into hedging contracts, but to mitigate exposure to fluctuations in foreign exchange the Company uses strategies to reduce the volatility of United States Dollar assets including converting excess United States dollars to Canadian dollars. As at December 31, 2021, the Company held net U.S. dollar assets totaling US$1,177,291. Accordingly, a hypothetical 10% change in the value of one United States dollar expressed in Canadian dollars as at December 31, 2021 would have had an approximately $150,039 effect on the unrealized foreign exchange gain or loss for the period. b) Derivative financial instruments As at December 31, 2021 and 2020, the Company held no derivative financial instruments.

Significant accounting policies
Basis Of Presentation	These consolidated financial statements for the period ended December 31, 2021 have been prepared by management in accordance with US GAAP.
Consolidation	These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries (all of which are inactive). All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements.
Cash And Cash Equivalents	Cash and cash equivalents consist of cash on hand and short term Guaranteed Investment Certificates (“GIC’s”) with an original maturity less than 90 days from the date of acquisition.
Short Term Investments	Short term investments consist of short term GICs, with original maturity dates greater than 90 days and up to one year.
Derivative Instruments	Derivative instruments are recognized on the balance sheet at fair value with any changes in fair value between periods recognized in the determination of net income (loss) for the period. NXT does not apply hedge accounting to any of its derivatives. As at December 31, 2021 and 2020, NXT had no outstanding derivative instruments.
Fair Value Measures	For any balance sheet items recorded at fair value on a recurring basis or non-recurring basis, the Company is required to classify the fair value measure into one of three categories based on the fair value hierarchy noted below. In Level I, the fair value of assets and liabilities is determined by reference to quoted prices in active markets for identical assets and liabilities that the Company has the ability to assess at the measurement date. At December 31, 2021, the fair value of the restricted stock units (“RSU”) liability based on share price was determined using Level I inputs. In Level II, determination of the fair value of assets and liabilities is based on the extrapolation of inputs, other than quoted prices included within Level I, for which all significant inputs are observable directly or indirectly. Such inputs include published exchange rates, interest rates, yield curves and stock quotes from external data service providers. Transfers between Level I and Level II would occur when there is a change in market circumstances. In Level III, the fair value of assets and liabilities measured on a recurring basis is determined using a market approach based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities measured at fair value can fluctuate between Level II and Level III depending on the proportion of the value of the contract that extends beyond the time frame for which inputs are considered to be observable. As contracts near maturity and observable market data becomes available, the contracts are transferred out of Level III and into Level II. The determination of the fair value of the acquisition of the Intellectual property (Note 9) was determined using Level III inputs.
Measurement Of Credit Losses On Financial Instruments	The impairment model of financial instruments is based on expected losses rather than incurred losses. In making the assessment of expected losses, the Company considers the following factors: historically realized bad debts; a counterparty’s present financial condition and whether a counterparty has breached certain contracts; the probability that a counterparty will enter bankruptcy; changes in economic conditions that correlate to increased levels of default and term to maturity of the specific receivable. These expected credit losses are recognized as an allowance rather than as a direct write-down of the amortized cost basis.
Deposits	Deposits consist of security payments made to lessors for the Company’s office and aircraft lease. They are classified as long term if the lease end date is greater than one year.
Property And Equipment	Property and equipment is recorded at cost, less accumulated amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods: Computer hardware (including survey equipment) 30% declining balance Aircraft equipment 10% declining balance Furniture and other equipment 20% declining balance Leasehold improvements 10% declining balance
Intellectual Property	Intellectual property acquired is recorded at cost, less accumulated amortization, which is recorded over the estimated minimum useful life of the assets. The Company incurs periodic costs that are expensed when incurred to file patents and to maintain them.
Impairment Of Long-lived Assets	The Company reviews long-lived assets, which includes property, equipment and intellectual property for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company considers both internal and external factors when assessing for potential indicators of impairment, and with respect to intellectual property, the Company’s assessment includes consideration of historical and forecasted SFD ® ® When indicators of impairment exist, the Company first compares the total of the estimated undiscounted future cash flows or the estimated sale price to the carrying value of an asset. If the carrying value exceeds these amounts, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the asset.
Research And Development Expenditure	Research and development (“R&D”) expenditures incurred to develop, improve and test the SFD ®
Foreign Currency Translation	The Company’s functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in effect at the end of the applicable period. Non-monetary assets and liabilities are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the period.
Income Taxes	NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized. The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.
Stock Based Compensation	NXT follows the fair value method of accounting for stock options, restricted stock units, deferred stock units, and the employee share purchase plan (the “Share Compensation Plans”) that are granted to acquire common shares under NXT’s Share Compensation Plans. For equity-settled stock-based compensation awards, fair values are determined at the grant date and the expense, net of estimated forfeitures, is recognized over the requisite service period with a corresponding increase recorded in contributed capital. An adjustment is made to compensation for any differences between the estimated forfeitures and the actual forfeitures. For cash-settled stock-based compensation awards, fair values, based on observable prices, are determined at each reporting date and periodic changes are recognized as compensation costs, with a corresponding change to liabilities. Upon exercise or realization of the equity-settled Share Compensation Plans, the consideration received by NXT, and the related amount which previously recorded in contributed capital, is recognized as an increase in the recorded value of the common shares of the Company.
Income (loss) Per Share	Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period. Shares issued during the period are weighted for the portion of the period that the shares were outstanding. Diluted income per share, in periods when NXT has net income, is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and restricted stock units. The incremental number of shares added under the treasury stock method assumes that outstanding stock options and restricted stock units that are exercisable at exercise prices below the Company’s average market price (i.e. they were “in-the-money”) for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company’s shares for the applicable fiscal period. No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case where there is a net loss for the period).
Revenue	SFD ® Surveys The performance obligation for NXT in SFD ® ® ® The Company uses direct survey costs as the input measure to recognize revenue in any fiscal period. The percentage of direct survey costs incurred to date over the total expected survey costs to be incurred, provides an appropriate measure of the stage of the performance obligation being satisfied over time. SFD ® Data Sales The performance obligation for NXT in SFD ® ® The Company determines if an arrangement is an operating or finance lease, as defined under U.S. GAAP, at inception. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. These leases are included in right-of-use (“ROU”) assets and lease obligations in the Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease obligations represent the obligation to make lease payments arising from such leases. Lease obligations are recognized at the lease commencement date based on the present value of remaining lease payments over the lease term, taking into consideration conditions such as incentives and termination penalties, as appropriate. A corresponding ROU asset is recognized at the amount of the lease obligation, adjusted for payments made prior to lease commencement or initial direct costs, if any. When calculating the present value, the Company uses the rate implicit in the lease, or uses its incremental borrowing rate for a similar term and risk profile based on the information available at the commencement date. The Company’s lease terms may have options to extend or terminate the lease which are included in the calculation of lease obligations when it is reasonably certain that it will exercise those options. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Office and equipment lease expenses are included within General and administrative expenses; the aircraft lease cost is included within SFD ® Lease agreements can contain both lease and non-lease components, which are accounted for separately. During 2021 the Company determined that the amounts previously recorded for the Aircraft lease were calculated incorrectly and the United States Dollar denominated lease liability had not been re-measured to Canadian Dollars each reporting period as required. The result of these corrections are to reduce the value of both the Right of use assets and Lease obligations, with changes to related income statement. The Company has determined that the effect of these adjustments are not material. The Company has recorded the adjustments in the related accounts in the comparative periods in these financial statements. On the balance sheet and income statement, the specific accounts affected are Deposits, Right of use assets, Current portion of lease obligations, Long-term lease obligations, Deficit, SFD ® Balance Sheet December 31, 2020 As previously reported Adjustments Adjusted Deposits $ 526,560 $ (100,730 ) $ 425,830 Right of use assets 2,415,430 (423,658 ) 1,991,772 Current portion of lease obligations (773,465 ) 85,474 (687,991 ) Long-term portion of lease obligations (1,896,277 ) 494,430 (1,401,847 ) Deficit 83,934,230 (55,516 ) 83,878,714 Income Statement For the year ended December 31, 2020 As previously reported Adjustments Adjusted SFD ® $ 1,091,587 $ 19,483 $ 1,111,070 Interest (income) expense (11,535 ) (2,527 ) (14,062 ) Foreign exchange loss (gain) (76,029 ) 11,597 (64,432 ) Net loss (5,999,675 ) (28,553 ) (6,028,228 ) Income Statement For the year ended December 31, 2019 As previously reported Adjustments Adjusted SFD ® $ 2,611,086 $ 41,969 $ 2,653,055 Interest (income) expense (20,684 ) (8,275 ) (28,959 ) Foreign exchange loss (gain) 233,231 (55,495 ) 177,736 Net income 3,772,908 21,801 3,794,709 Deficit 77,934,555 (84,069 ) 77,850,486 Accounting for the above adjustments, the adoption of Topic 842 resulted in the initial recognition of right-of-use assets of approximately $3.2 million, current lease liabilities of approximately $0.7 million, and non-current lease liabilities of approximately $2.8 million as at January 1, 2019. Before the above retrospective adjustments, at January 1, 2019, the Company recorded the initial recognition of right-of-use assets of approximately $3.5 million, current lease liabilities of approximately $0.7 million, and non-current lease liabilities of approximately $3.4 million. The disclosures in notes 5, 6, 8, 13, 17, 19 and 23 have also been revised.
Consolidated Statement Of Cash Flows	In the preparation of the annual financial statements as at and for the year ended December 31, 2021, the Company has determined that certain amounts previously recorded in the 2019 and 2020 consolidated statements of cash flows were not correctly calculated to properly reflect payments on the financial liability, lease obligation payments and accretion, and application of exchange rates to calculate unrealized foreign exchange (gain) loss including the effect of foreign exchange on changes on cash and cash equivalents. The adjustments to correct the respective financial statement line items are not material and did not change the Cash, SFD® related revenues, or Net income (loss) accounts or basic and diluted loss per share. The Company has recorded the adjustments in the related line items in each of the comparative periods. Line items affected on the Consolidated Statement of Cash Flows by the adjustment are: Non-cash lease costs, Change in the carrying amount of right of use assets and lease liabilities, unrealized foreign exchange (gain) loss, Repayment of financial liability and finance lease obligations, Proceeds from (used in) short-term investments, and Effect of foreign exchange rate changes on cash and cash equivalents.

Government Grants	Government grants are recognized when there is reasonable assurance that the grant will be received, and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as an expense reduction in the period in which the costs are incurred. Where the grant relates to an asset, it is recognized as a reduction to the net book value of the related asset and then subsequently in net loss over the expected useful life of the related asset through lower charges to amortization and impairment.
