GENERAL INFORMATION AND NATURE OF OPERATIONS
GENERAL INFORMATION AND NATURE OF OPERATIONS	1. GENERAL INFORMATION, NATURE OF OPERATIONS International Tower Hill Mines Ltd. (“ITH” or the "Company") is incorporated under the laws of British Columbia, Canada. The Company’s head office address is 2300‑1177 West Hastings Street, Vancouver, British Columbia, Canada. International Tower Hill Mines Ltd. consists of ITH and its wholly owned subsidiaries Tower Hill Mines, Inc. (“TH Alaska”) (an Alaska corporation), Tower Hill Mines (US) LLC (“TH US”) (a Colorado limited liability company), and Livengood Placers, Inc. (“LPI”) (a Nevada corporation). The Company is in the business of acquiring, exploring and evaluating mineral properties, and either joint venturing or developing these properties further or disposing of them when the evaluation is completed. At December 31, 2019, the Company was in the exploration stage and controls a 100% interest in its Livengood Gold Project in Alaska, U.S.A. These consolidated financial statements have been prepared on a going-concern basis, which presumes the realization of assets and discharge of liabilities in the normal course of business for the foreseeable future. The Company will require significant additional financing to continue its operations in connection with advancing activities at the Livengood Gold Project and for the development of any mine that may be determined to be built at the Livengood Gold Project. There is no assurance that the Company will be able to obtain the additional financing required on acceptable terms, if at all. In addition, any significant delays in the issuance of required permits for the ongoing work at the Livengood Gold Project, or unexpected results in connection with the ongoing work, could result in the Company being required to raise additional funds to advance permitting efforts. The Company’s review of its financing options includes pursuing a future strategic alliance to assist in further development, permitting and future construction costs. Despite the Company’s success to date in raising significant equity financing to fund its operations, there is significant uncertainty that the Company will be able to secure any additional financing in the current or future equity markets. The amount of funds to be raised and the terms of any proposed equity financing that may be undertaken will be negotiated by management as opportunities to raise funds arise. Specific plans related to the use of proceeds will be devised once financing has been completed and management knows what funds will be available for these purposes. Due to this uncertainty, if the Company is unable to secure additional financing, it may be required to reduce all discretionary activities at the Project to preserve its working capital to fund anticipated non-discretionary expenditures beyond the 2020 fiscal year. As at March 9, 2020, management believes that the Company has sufficient financial resources to maintain its operations for the next twelve months.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation These consolidated financial statements are presented in United States dollars and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). On March 9, 2020, the Board approved the consolidated financial statements dated December 31, 2019. Basis of consolidation These consolidated financial statements include the accounts of ITH and its wholly owned subsidiaries TH Alaska, TH US, and LPI. All intercompany transactions and balances have been eliminated. Significant judgments, estimates and assumptions The preparation of financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the period. These judgments, estimates and assumptions are regularly evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. While management believes the estimates to be reasonable, actual results could differ from those estimates and could impact future results of operations and cash flows. The areas which require significant judgment and estimates that management has made at the financial reporting date, that could result in a material change to the carrying amounts of assets and liabilities, in the event actual results differ from the assumptions made, relate to, but are not limited to the following: Significant judgments  the determination of functional currencies;  quantitative and qualitative factors used in the assessment of impairment of the Company’s capitalized acquisition costs; and  the analysis of resource calculations, drill results, labwork, etc. which can impact the Company’s assessment of impairment, and provisions, if any, for environmental rehabilitation and restoration. Cash and cash equivalents Cash equivalents include highly liquid investments with original maturities of twelve months or less, and which are subject to an insignificant risk of change in value. Cash equivalents are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes. Marketable securities Marketable securities held in companies with an active market are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value in the financial statements with unrealized gains and losses recorded in accumulated other comprehensive income. Accumulated unrealized gains and losses are recognized in the statement of operations upon the sale of the security or if the security is determined to be impaired. Property and equipment On initial recognition, property and equipment are valued at cost. Property and equipment is subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not depreciated. Depreciation is recorded over the estimated useful life of the assets at the following annual rates: Computer equipment - 30% declining balance; Computer software - 3 years straight line; Furniture and equipment -20% declining balance; and Leasehold improvements - straight-line over the lease term. Additions during the year are depreciated at one-half the annual rates. Depreciation methods, useful lives and residual values are reviewed at each financial year-end and adjusted if appropriate. Mineral properties and exploration and evaluation expenditures The Company’s mineral project is currently in the exploration and evaluation phase. Mineral property acquisition costs are capitalized when incurred. Mineral property exploration costs are expensed as incurred. At such time that the Company determines that a mineral property can be economically developed, subsequent mineral property expenses will be capitalized during the development of such property. The Company assesses interests in exploration properties for impairment when facts and circumstances suggest that the carrying amount of an asset may exceed its recoverable amount. Impairment analysis includes assessment of the following circumstances: a significant decrease in the market price of a long-lived asset or asset group; a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset or asset group, including an adverse action or assessment by a regulator; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or asset group; a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The term more likely than not refers to a level of likelihood that is more than 50%. Asset retirement obligations The Company records a liability based on the best estimate of costs for site closure and reclamation activities that the Company is legally or contractually required to remediate. The provision for closure and reclamation liabilities is estimated using expected cash flows based on engineering and environmental reports and accreted to full value over time through periodic charges to income. The Company does not have any material provisions for environmental rehabilitation as of December 31, 2019. Impairment of long-lived assets and long-lived assets to be disposed of Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount and the fair value less costs to sell. Income taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax 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. Under the asset and liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion or the entire deferred tax asset will not be recognized. Net loss per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if securities or contracts that may require the issuance of common shares in the future were converted, unless the impact is anti-dilutive. For the year ended December 31, 2019, this calculation proved to be anti-dilutive, and therefore the Company’s 2,452,049 stock options and 1,383,396 deferred share units (“DSUs”) outstanding at year-end have been excluded from the calculation. Stock-based compensation The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Section 718 “Compensation - Stock Compensation”, which establishes accounting for equity based compensation awards to be accounted for using the fair value method. Equity-settled share based payment arrangements are initially measured at fair value at the date of grant and recorded within shareholders’ equity. Arrangements considered to be cash-settled are initially recorded at fair value and classified as accrued liabilities, and subsequently re-measured at fair value at each reporting date. The Company’s stock option plan is an equity-settled arrangement and the Company’s deferred share unit plan can be an equity or cash settled arrangement depending on the grant date term. The fair value at grant date of all share-based payments is recognized as compensation expense over the period for which benefits of services are expected to be derived, with a corresponding credit to shareholders’ equity or accrued liabilities depending on whether they are equity-settled or cash-settled. The Company estimates the fair value of stock options granted using the Black-Scholes option pricing model and estimate the expected forfeiture rate at the date of grant. The value of DSUs is estimated based on the quoted market price of the Company’s common shares. When awards are forfeited because non-market based vesting conditions are not satisfied, the expense previously recognized is proportionately reversed. Functional Currency The Company’s consolidated financial statements are presented in U.S. dollars, which is the Company’s reporting currency. The functional currency of ITH is the Canadian (“CAD” or “C”) dollar and the functional currency of ITH Alaska, TH US and LPI is the U.S. dollar. In accordance with ASC 830, Foreign Currency Matters, the Company translates the assets and liabilities into U.S. dollars using the rate of exchange prevailing at the balance sheet date and the statements of operations and comprehensive loss and cash flows are translated at an average rate during the reporting period. Adjustments resulting from the translation from CAD into U.S. dollars are recorded in shareholders’ equity as part of accumulated other comprehensive income. Foreign currency transactions are translated into the functional currency of the respective currency of the entity or division, using the exchange rates prevailing at the dates of the transactions (spot exchange rate). Foreign exchange gains and losses resulting from the settlement of such transactions and from the re-measurement of monetary items denominated in foreign currency at period-end exchange rates are recognized in profit or loss. Non-monetary items that are not re-translated at period end are measured at historical cost (translated using the exchange rates at the transaction date), except for non-monetary items measured at fair value, which are translated using the exchange rates as at the date when fair value was determined. Gains and losses are recorded in the statement of operations and comprehensive loss. Recently Adopted Accounting Pronouncements Accounting Standards Update No. 2016-02 Leases (Topic 842). In February 2016, the FASB issued a new standard regarding leases. These are elements of the new standard that could impact almost all entities to some extent, although lessees will likely see the most significant changes. Lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and a lease liability. The Company adopted the standards on January 1, 2019 and adoption had no impact on the Company’s financial statements. Accounting Standards Update 2016‑16—Income Taxes, Intra-Entity Transfers of Assets Other Than Inventory (Topic 740). In October 2016, the FASB issued guidance intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory by requiring an entity to recognize the income tax consequences when a transfer occurs, instead of when an asset is sold to an outside party. The adoption of the guidance had no impact on the Company’s financial statements. Accounting Standards Update No. 2014‑09—Revenue from Contracts with Customers (Topic 606). On May 28, 2014, the FASB issued guidance that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU was further amended in August 2015, March 2016, April 2016, May 2016 and December 2016 by ASU No. 2015‑014, No. 2016‑08, No. 2016‑10, No. 2016‑12 and No. 2016‑20, respectively. The guidance provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. The adoption of the guidance had no impact on the Company’s financial statements.

FAIR VALUE OF FINANCIAL INSTRUMENTS	3. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying values of cash and cash equivalents, accounts payable and accrued liabilities approximate their fair values due to the short-term maturity of these financial instruments. Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the significance of the inputs used in making the measurement. The three levels of the fair value hierarchy are as follows: · Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities; · Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and, · Level 3 – Inputs that are not based on observable market data.

Exploration Inc. (“AngloGold”) and TH Alaska, the Company acquired all of AngloGold’s interest in a portfolio of seven mineral exploration projects in Alaska and referred to as the Livengood, Chisna, Gilles, Coffee Dome, West Pogo, Blackshell, and Caribou properties (the “Sale Properties”) in exchange for a cash payment of $50,000 on August 4, 2006, and the issuance of 5,997,295 common shares, representing approximately 19.99% of the Company’s issued shares following the closing of the acquisition and two private placement financings raising an aggregate of C$11,479,348. As further consideration for the transfer of the Sale Properties, the Company granted to AngloGold a 90‑day right of first offer with respect to the Sale Properties and any additional mineral properties in Alaska in which the Company acquires an interest and which interest the Company proposes to farm out or otherwise dispose of. Upon AngloGold’s equity interest in the Company being reduced to less than 10%, this right of first offer would then terminate. On December 11, 2014, the Company closed a private placement financing in which AngloGold elected not to participate. As a result of the shares issued in this private placement, AngloGold’s ownership in the Company was reduced to less than 10% and thus both AngloGold’s right to maintain its ownership percentage interest and its right of first offer on the Company’s Alaskan properties terminated upon the closing of the December 2014 private placement. Details of the Livengood Property (being the only Sale Property still held by the Company) are as follows: Livengood Property: The Livengood property is located in the Tintina gold belt approximately 113 kilometers (70 miles) north of Fairbanks, Alaska. The property consists of land leased from the Alaska Mental Health Trust, a number of smaller private mineral leases, Alaska state mining claims purchased or located by the Company and patented ground held by the Company. Details of the leases are as follows: a) a lease of the Alaska Mental Health Trust mineral rights having a term beginning July 1, 2004 and extending 19 years until June 30, 2023, subject to further extensions beyond June 30, 2023 by either commercial production or payment of an advance minimum royalty equal to 125% of the amount paid in year 19 and diligent pursuit of development. The lease requires minimum work expenditures and advance minimum royalties which escalate annually with inflation. A net smelter return (“NSR”) production royalty of between 2.5% and 5.0% (depending upon the price of gold) is payable to the lessor with respect to the lands subject to this lease. In addition, an NSR production royalty of l% is payable to the lessor with respect to the unpatented federal mining claims subject to the lease described in b) below and an NSR production royalty of between 0.5% and 1.0% (depending upon the price of gold) is payable to the lessor with respect to the lands acquired by the Company as a result of the purchase of Livengood Placers, Inc. in December 2011. As of December 31, 2019, the Company has paid $3,306,615 from the inception of this lease. b) a lease of federal unpatented lode mining claims having an initial term of ten years commencing on April 21, 2003 and continuing for so long thereafter as advance minimum royalties are paid and mining related activities, including exploration, continue on the property or on adjacent properties controlled by the Company.

COMMITMENTS	9 . COMMITMENTS The following table discloses, as of December 31, 2019, the Company’s contractual obligations including anticipated mineral property payments and work commitments. Under the terms of the Company’s mineral property purchase agreements, mineral leases and the terms of the unpatented mineral claims held by it, the Company is required to make certain scheduled acquisition payments, incur certain levels of expenditures, make lease or advance royalty payments, make payments to government authorities and incur assessment work expenditures as summarized in the table below in order to maintain and preserve the Company’s interests in the related mineral properties. If the Company is unable or unwilling to make any such payments or incur any such expenditures, it is likely that the Company would lose or forfeit its rights to acquire or hold the related mineral properties.

After the initial one-year lease period, the agreement may renew on a month-to-month basis. The Company does not consider any additional renewal periods to be reasonably certain of being exercised and has therefore elected the short-term lease recognition exemption for the office lease. Accordingly, office lease costs will continue to be reported as rent expense on the Consolidated Statements of Operations and Comprehensive Loss and the Company will not recognize a right-of-use model (ROU) asset or lease liability on the Consolidated Balance Sheets.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of presentation	Basis of presentation These consolidated financial statements are presented in United States dollars and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). On March 9, 2020, the Board approved the consolidated financial statements dated December 31, 2019.
Basis of consolidation	Basis of consolidation These consolidated financial statements include the accounts of ITH and its wholly owned subsidiaries TH Alaska, TH US, and LPI. All intercompany transactions and balances have been eliminated.
Significant judgments, estimates and assumptions	Significant judgments, estimates and assumptions The preparation of financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the period. These judgments, estimates and assumptions are regularly evaluated and are based on management’s experience and knowledge of the relevant facts and circumstances. While management believes the estimates to be reasonable, actual results could differ from those estimates and could impact future results of operations and cash flows. The areas which require significant judgment and estimates that management has made at the financial reporting date, that could result in a material change to the carrying amounts of assets and liabilities, in the event actual results differ from the assumptions made, relate to, but are not limited to the following: Significant judgments  the determination of functional currencies;  quantitative and qualitative factors used in the assessment of impairment of the Company’s capitalized acquisition costs; and  the analysis of resource calculations, drill results, labwork, etc. which can impact the Company’s assessment of impairment, and provisions, if any, for environmental rehabilitation and restoration.
Cash and cash equivalents	Cash and cash equivalents Cash equivalents include highly liquid investments with original maturities of twelve months or less, and which are subject to an insignificant risk of change in value. Cash equivalents are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes.
Marketable securities	Marketable securities Marketable securities held in companies with an active market are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value in the financial statements with unrealized gains and losses recorded in accumulated other comprehensive income. Accumulated unrealized gains and losses are recognized in the statement of operations upon the sale of the security or if the security is determined to be impaired.
Property and equipment	Property and equipment On initial recognition, property and equipment are valued at cost. Property and equipment is subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not depreciated. Depreciation is recorded over the estimated useful life of the assets at the following annual rates: Computer equipment - 30% declining balance; Computer software - 3 years straight line; Furniture and equipment -20% declining balance; and Leasehold improvements - straight-line over the lease term. Additions during the year are depreciated at one-half the annual rates. Depreciation methods, useful lives and residual values are reviewed at each financial year-end and adjusted if appropriate.
Mineral properties and exploration and evaluation expenditures	Mineral properties and exploration and evaluation expenditures The Company’s mineral project is currently in the exploration and evaluation phase. Mineral property acquisition costs are capitalized when incurred. Mineral property exploration costs are expensed as incurred. At such time that the Company determines that a mineral property can be economically developed, subsequent mineral property expenses will be capitalized during the development of such property. The Company assesses interests in exploration properties for impairment when facts and circumstances suggest that the carrying amount of an asset may exceed its recoverable amount. Impairment analysis includes assessment of the following circumstances: a significant decrease in the market price of a long-lived asset or asset group; a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset or asset group, including an adverse action or assessment by a regulator; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or asset group; a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The term more likely than not refers to a level of likelihood that is more than 50%.
Asset retirement obligations	Asset retirement obligations The Company records a liability based on the best estimate of costs for site closure and reclamation activities that the Company is legally or contractually required to remediate. The provision for closure and reclamation liabilities is estimated using expected cash flows based on engineering and environmental reports and accreted to full value over time through periodic charges to income. The Company does not have any material provisions for environmental rehabilitation as of December 31, 2019.
Impairment of long-lived assets and long-lived assets to be disposed of	Impairment of long-lived assets and long-lived assets to be disposed of Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount and the fair value less costs to sell.
Income taxes	Income taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax 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. Under the asset and liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion or the entire deferred tax asset will not be recognized.
Net loss per share	Net loss per share Basic loss per share is calculated using the weighted average number of common shares outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if securities or contracts that may require the issuance of common shares in the future were converted, unless the impact is anti-dilutive. For the year ended December 31, 2019, this calculation proved to be anti-dilutive, and therefore the Company’s 2,452,049 stock options and 1,383,396 deferred share units (“DSUs”) outstanding at year-end have been excluded from the calculation.
Stock-based compensation	Stock-based compensation The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Section 718 “Compensation - Stock Compensation”, which establishes accounting for equity based compensation awards to be accounted for using the fair value method. Equity-settled share based payment arrangements are initially measured at fair value at the date of grant and recorded within shareholders’ equity. Arrangements considered to be cash-settled are initially recorded at fair value and classified as accrued liabilities, and subsequently re-measured at fair value at each reporting date. The Company’s stock option plan is an equity-settled arrangement and the Company’s deferred share unit plan can be an equity or cash settled arrangement depending on the grant date term. The fair value at grant date of all share-based payments is recognized as compensation expense over the period for which benefits of services are expected to be derived, with a corresponding credit to shareholders’ equity or accrued liabilities depending on whether they are equity-settled or cash-settled. The Company estimates the fair value of stock options granted using the Black-Scholes option pricing model and estimate the expected forfeiture rate at the date of grant. The value of DSUs is estimated based on the quoted market price of the Company’s common shares. When awards are forfeited because non-market based vesting conditions are not satisfied, the expense previously recognized is proportionately reversed.
Functional Currency	Functional Currency The Company’s consolidated financial statements are presented in U.S. dollars, which is the Company’s reporting currency. The functional currency of ITH is the Canadian (“CAD” or “C”) dollar and the functional currency of ITH Alaska, TH US and LPI is the U.S. dollar. In accordance with ASC 830, Foreign Currency Matters, the Company translates the assets and liabilities into U.S. dollars using the rate of exchange prevailing at the balance sheet date and the statements of operations and comprehensive loss and cash flows are translated at an average rate during the reporting period. Adjustments resulting from the translation from CAD into U.S. dollars are recorded in shareholders’ equity as part of accumulated other comprehensive income. Foreign currency transactions are translated into the functional currency of the respective currency of the entity or division, using the exchange rates prevailing at the dates of the transactions (spot exchange rate). Foreign exchange gains and losses resulting from the settlement of such transactions and from the re-measurement of monetary items denominated in foreign currency at period-end exchange rates are recognized in profit or loss. Non-monetary items that are not re-translated at period end are measured at historical cost (translated using the exchange rates at the transaction date), except for non-monetary items measured at fair value, which are translated using the exchange rates as at the date when fair value was determined. Gains and losses are recorded in the statement of operations and comprehensive loss.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Accounting Standards Update No. 2016-02 Leases (Topic 842). In February 2016, the FASB issued a new standard regarding leases. These are elements of the new standard that could impact almost all entities to some extent, although lessees will likely see the most significant changes. Lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and a lease liability. The Company adopted the standards on January 1, 2019 and adoption had no impact on the Company’s financial statements. Accounting Standards Update 2016‑16—Income Taxes, Intra-Entity Transfers of Assets Other Than Inventory (Topic 740). In October 2016, the FASB issued guidance intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory by requiring an entity to recognize the income tax consequences when a transfer occurs, instead of when an asset is sold to an outside party. The adoption of the guidance had no impact on the Company’s financial statements. Accounting Standards Update No. 2014‑09—Revenue from Contracts with Customers (Topic 606). On May 28, 2014, the FASB issued guidance that requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU was further amended in August 2015, March 2016, April 2016, May 2016 and December 2016 by ASU No. 2015‑014, No. 2016‑08, No. 2016‑10, No. 2016‑12 and No. 2016‑20, respectively. The guidance provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. The adoption of the guidance had no impact on the Company’s financial statements.
