Nature Of Business And Liquidity [Text Block]

Nature of Business and Liquidity

Fennec Pharmaceuticals Inc. (“Fennec,” “the Company,” “we,” “us,” or “our”) was originally formed as a British Columbia corporation under the name Adherex Technologies Inc. and subsequently changed its name on September 3, 2014. Fennec, together with its wholly owned subsidiaries Oxiquant, Inc. (“Oxiquant”) and Fennec Pharmaceuticals, Inc., both Delaware corporations, and Cadherin Biomedical Inc. (“CBI”), a Canadian corporation and Fennec Pharmaceuticals (EU) Limited (“Fennec Limited”), collectively referred to herein as the “Company,” is a biopharmaceutical company with a product candidate under development for use in the treatment of cancer. With the exception of Fennec Pharmaceuticals, Inc., all subsidiaries are inactive.

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”) that are applicable to a going concern which contemplates that the Company will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities in the normal course of business.

During the year ended December 31, 2018, the Company incurred a net loss from operations of $10,409 and still has not earned any revenue in its history. At December 31, 2018, it had an accumulated deficit of $131,256 and had experienced negative cash flows from operating activities in the amount of $7,826 for the year ended December 31, 2018.

On February 1, 2019, Fennec entered into a Loan and Security Agreement with Bridge Bank, a division of Western Alliance Bank, an Arizona corporation, pursuant to which the Bank agreed to loan $12.5 million to the Company, to be made available upon New Drug Application NDA approval of PEDMARK by no later than September 30, 2020. The proceeds from the loan will be used for working capital purposes and to fund general business requirements in accordance with the terms of the Loan and Security Agreement. Interest under the Term Loans shall bear interest, on the outstanding daily balance thereof, at a floating per annum rate equal to the Effective Interest Rate (as defined in the Loan and Security Agreement) which is equal to the sum of the Prime Rate published in the Wall Street Journal (currently 5.50%) plus one percent (1.00%). The debt facility is to have interest-only monthly payments due for the first eighteen months from the funding date and then monthly principal and interest payments are due through the remainder of the term which has a maturity date of October 1, 2023. In connection with the facility, Fennec has agreed to grant Bridge Bank a warrant to purchase up to 39,130 common shares at an exercise price of $6.80 per common share, for a term of ten years from the date of issuance, subject to early termination under certain conditions.

The Company believes the aforementioned raise, along with the current cash on hand, provides sufficient funding for the Company to carry-out its planned activities for the next twelve to eighteen months as it continues its strategic development of PEDMARK

These financial statements do not reflect the potentially material adjustments in the carrying values of assets and liabilities, the reported expenses, and the balance sheet classifications used, that would be necessary if the going concern assumption were not appropriate.

Accounting Policies [Abstract]

Significant Accounting Policies

Basis of presentation

The consolidated financial statements include the accounts of Fennec and of all its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated upon consolidation.

Use of estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that impact the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates include the valuation of derivative warrant liability and the valuation of stock-based compensation. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with original maturities at the date of purchase of three months or less.

The Company places its cash and cash equivalents in investments held by highly rated financial institutions in accordance with its investment policy designed to protect the principal investment. At December 31, 2018, the Company had $22.8 million in cash and money market accounts (2017- $28.3 million). Money market investments typically have minimal risks. The Company has not experienced any loss or write-down of its money market investments.

Financial instruments

Financial instruments recognized on the balance sheets at December 31, 2018 and December 31, 2017 consist of cash and cash equivalents, accounts payable, accrued liabilities and derivative instruments, the carrying values of which, with the exception of the derivative instruments, approximate fair value due to their relatively short time to maturity. The Company does not hold or issue financial instruments for trading. The derivative liabilities are carried at fair value.

The Company’s investment policy is to manage investments to achieve, in the order of importance, the financial objectives of preservation of principal, liquidity and return on investment. Investments, when made, are made in U.S. or Canadian bank securities, commercial paper of U.S. or Canadian industrial companies, utilities, financial institutions and consumer loan companies, and securities of foreign banks provided the obligations are guaranteed or carry ratings appropriate to the policy. Securities must have a minimum Dun & Bradstreet rating of A for bonds or R1 low for commercial paper.

The policy risks are primarily the opportunity cost of the conservative nature of the allowable investments. As the main purpose of the Company is research and development, the Company has chosen to avoid investments of a trading or speculative nature.

Common shares and warrants

The Company has warrants outstanding to purchase common shares that were denominated in both United States dollars (“USD”) and Canadian dollars (“CAD”), which resulted in the Company having warrants outstanding that were denominated outside of the Company’s U.S. dollar functional currency.

The Company’s outstanding warrants denominated in Canadian dollars were not considered to be indexed to the Company’s own stock and should therefore be treated as derivative financial instruments and recorded at their fair value as a liability. During the year ended December 31, 2018, all warrants accounted for as derivatives were exercised. These exercises reduced the derivative liability to

$0 as of December 31, 2018.

At December 31, 2017, the derivative liabilities were valued at approximately $167,000. There was an unrealized, non-cash gain on derivative liabilities of approximately

$167,000

for the year ended December 31, 2018, whereas there was an unrealized loss of approximately

$134,000 during the year ended December 31, 2017

Revenue recognition

At this time, the Company does not have any revenue.

Research and development costs and investment tax credits

Research costs, including employee compensation, laboratory fees, lab supplies, and research and testing performed under contract by third parties, are expensed as incurred. Development costs, including drug substance costs, clinical study expenses and regulatory expenses are expensed as incurred.

Investment tax credits, which are earned as a result of qualifying research and development expenditures, are recognized when the expenditures are made, and their realization is reasonably assured. They are applied to reduce related capital costs and research and development expenses in the year recognized.

Income taxes

The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and liabilities and the related financial amounts, using currently enacted tax rates. The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. As of December 31, 2018, we maintained a full valuation allowance against our deferred tax assets.

The provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740-10, Uncertainty in Income Taxes, address the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position.

Foreign currency translation

The U.S. dollar is the functional currency for the Company’s consolidated operations. All gains and losses from currency translations are included in results of operations.

Loss per share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the year. Diluted net earnings per share is computed using the same method, except the weighted average number of common shares outstanding includes convertible debentures, stock options and warrants, if dilutive, as determined using the if-converted method and treasury methods. Accordingly, options to purchase 2.5 million of our common shares at December 31, 2018, were not included in earnings per share. Such options would have an antidilutive effect. In 2017, options to purchase 2.3 million common shares and warrants to purchase 1.4 million of our common shares were excluded from the computation of earnings per share as their inclusion would have been antidilutive.

Recent accounting pronouncements

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 removes certain disclosures, modifies certain disclosures and adds additional disclosures. The ASU is effective for us on January 1, 2020, and interim periods within that fiscal year. Early adoption is permitted. Certain disclosures in ASU 2018-13 would need to be applied on a retrospective basis and others on a prospective basis. We are currently evaluating the impact this guidance may have on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07 to expand the scope of ASC Topic 718, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to include share-based payment transactions for acquiring goods and services from nonemployees. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company concluded after evaluation, that the impact of ASU 2018-07 on our consolidated financial statements and disclosures was de minimis.

In February 2017, the FASB issued ASU No. 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (“ASU 2017-05”). ASU 2017-05 is meant to clarify the scope of the original guidance within Subtopic 610-20 that was issued in connection with ASU 2014-09, as defined below, which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also added guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for our fiscal year ending December 31, 2018 and we are required to adopt ASU 2017-05 concurrent with the adoption of ASU 2014-09. The Company adopted ASU 2017-05 January 1, 2018. The Company concluded after evaluation, that the impact of ASU 2017-05 on our consolidated financial statements and disclosures was de minimis.

In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). The FASB issued ASU 2017-09 to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying the guidance in Topic 718, to a change to the terms and conditions of a share-based payment award. This guidance became effective for the Company as of January 1, 2018. The amendments in this ASU have been applied prospectively to awards modified after the adoption date.

In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606), to clarify the principles for recognizing revenue. This update provides a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of the new standard from January 1, 2017 to January 1, 2018. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies certain aspects of identifying performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients related to disclosures of remaining performance obligations, as well as other amendments to guidance on collectability, non-cash consideration and the presentation of sales and other similar taxes collected from customers. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments. The amendments in ASU No. 2017-13 amends the early adoption date option for certain companies related to the adoption of ASU No. 2014-09 and ASU No. 2016-02. In November 2017, the FASB issued ASU No. 2017-14, Revenue from Contracts with Customers (Topic 606): Income Statement- Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), which amends certain SEC paragraphs within the FASB Accounting Standards Codification. These standards had the same effective date and transition date of January 1, 2018. The new revenue standard allows for either full retrospective or modified retrospective application. The Company currently does not have any revenue and therefore this update has virtually no effect on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new guidance requires the recognition of lease liabilities, representing future minimum lease payments, on a discounted basis, and corresponding right-of-use assets on a balance sheet for most leases, along with requirements for enhanced disclosures to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leasing arrangements. In July 2018, the FASB issued ASU 2018-10 and 2018-11 which permit application of the new guidance at the beginning of the year of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, in addition to the method of applying the new guidance retrospectively to each prior reporting period presented. The ASU is effective for us on January 1, 2019. We have concluded the impact of this guidance will be negligible on our consolidated financial statements, given we have no material leases.

Loss per Share

Earnings Per Share [Abstract]

Loss per Share

Loss per common share is presented under two formats: basic loss per common share and diluted loss per common share. Basic loss per common share is computed by dividing net loss attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period, plus the potentially dilutive impact of common shares equivalents (e.g. stock options and warrants). Dilutive common share equivalents consist of the incremental common shares issuable upon exercise of stock options and warrants. The following table sets forth the computation of basic and diluted net loss per share (in thousands except per share data):

Stock options

The Compensation Committee of the Board of Directors administers the Company’s stock option plan. The Compensation Committee designates eligible participants to be included under the plan and approves the number of options to be granted from time to time under the plan. On June 24, 2010, at the Company’s annual meeting, shareholders approved an amendment to the Company’s Stock Option Plan (the “Plan Maximum Amendment”). The Plan Maximum Amendment relates to changing the maximum number of common shares issuable under the stock option plan from a fixed number of 6.7 million to the number of shares that represents twenty-five percent (25%) of the total number of all issued and outstanding common shares. Based upon the current shares outstanding, a maximum of 5.0 million of our common shares are authorized for issuance under the plan. The option exercise price for all options issued under the plan is based on the fair value of the underlying shares on the date of grant. All options vest within three years or less and are exercisable for a period of seven years from the date of grant. The stock option plan, as amended, allows the issuance of Canadian and U.S. dollar grants. A summary of the stock option transactions, for both the Canadian and U.S. dollar grants, through the year ended December 31, 2018 is below.

Stock compensation expense for the fiscal years ended December 31, 2018 and 2017 was $2.1 million and $2.3 million respectively. These amounts have been included in the general and administrative expenses for the respective periods. The weighted average fair value per share of options granted and or vested during the fiscal years ended December 31, 2018 and 2017 was $9.12 and $5.27, respectively. The intrinsic value (being the difference between the share price at December 31, 2018 and exercise price) of stock options exercisable at December 31, 2018 was $8.6 million. The intrinsic value of options exercised during the fiscal year ended December 31, 2018 was $1.1 million. The fair value of all options vested during the fiscal year ended December 31, 2018 was $2.1 million.

The fair values of options granted in fiscal years ended December 31, 2018 and 2017 were estimated on the date the options were granted based on the Black-Scholes option-pricing model, using the following weighted average assumptions for all options with a seven-year expiration:

	Year Ended December 31, 2018			Year Ended December 31, 2017
Expected dividend		0	%		0	%
Risk-free interest rate		2.53– 3.00	%		2.04 – 2.33	%
Expected volatility		132 – 151	%		158 – 168	%
Expected life		4.5 - 7 years			7 years

The Company uses the historical volatility and adjusts for available relevant market information pertaining to the Company’s share price.

Modification of Existing Canadian Dollar Denominated Options

In 2018, the Company modified the terms of certain options granted to executives and directors by extending the expiration date by a weighted average amount of 2.0 years. The Company recorded option modification expense of approximately $112,000 included in general and administrative expense. The expense was calculated using the Black-Scholes valuation method with a June 7, 2018 exchange rate of $CAD/$USD 0.7715. The following table summarizes the effect of the June 7, 2018 transaction:

Number of Options		Expiration Date	Risk Free Rate			Exercise Price $CAD		Share Price $CAD		Expected Life (Years)		Volatility			Expense Recognized $USD
	648	08/18/2020		1.90	%		2.43		14.14		2.2		76	%		112

Shareholder rights plan

On June 27, 2017, the Company’s shareholders approved a Shareholder Rights Plan Agreement (the "Rights Plan") for the Company. The Rights Plan is to ensure, to the extent possible, that all shareholders of the Corporation are treated fairly and equally in connection with any take-over bid or other acquisition of control of the Corporation. The Rights Plan is designed to require any potential transaction that will result in a person owning, in the aggregate, 20% or more of the outstanding Common Shares to be structured as a formal take-over bid that satisfies certain minimum requirements relating primarily to the manner in which the bid must be made, the minimum number of days the bid must remain open, and the minimum number of shares that must be acquired under the bid.

Registration of Certain Common Shares, Options and Warrants (S-1, S-3 & S-8)

S-3 Resale

On August 11, 2017, the Company filed a Form S-1 (subsequently amended to Form S-3) registration statement with the SEC to register 11.9 million common shares, which includes 1.4 million common shares issuable upon exercise of warrants. The Form S-3 amendment became effective on April 19, 2018 and remains effective. This Form S-3 filing covers shareholders of common shares and warrants from the following transactions:

		The Company’s April 2010 private placement of common shares and warrants to purchase common shares;
		The Company’s November 2013 private placement of common shares and warrants to purchase common shares;
		The Company’s February 2016 private placements of warrants to purchase common shares in lieu of payment for services rendered;
		The Company’s May 2016 private placement of common shares; and
		The Company’s June 2017 private placement of common shares.

S-3 Primary

On October 24, 2017, the Company filed a Form S-3 registration statement with the SEC, pursuant to which the Company may offer from time to time, common shares having an aggregate offering price of up to $90.0 million. This Form S-3 became effective on November 3, 2016 and remains in effect. The Company used this Form S-3 to sell shares during a public offering which closed on December 12, 2017, from which the Company raised $21.2 million total gross proceeds. The Company may in the future offer shares for up to an aggregate of the remaining limit of this Form S-3 (approximately $68.8 million).

S-8

On October 24, 2017, the Company filed a Form S-8 registration statement with the SEC registering options to purchase 4.0 million of our common shares. The S-8 registration became effective upon filing and remains in effect.

Derivative Liabilities

Summary of Derivative Instruments [Abstract]

Derivative Liabilities

The Company's derivative instruments on January 1, 2018 included options to purchase 19,441 common shares, the exercise prices for which are denominated in a currency other than the Company's functional currency, as follows:

		Contractor options to purchase 17,394 common shares exercisable at CAD$1.62 per whole common share that expire on April 4, 2018;
		Contractor options to purchase 2,047 common shares exercisable at CAD$2.43 per whole common share that expire on May 18, 2018.

During the year ended December 31, 2018, all of these derivative options were exercised. This resulted in gross proceeds of $26,109, the issuance of 19,441 common shares and a non-cash, unrealized gain on the extinguishment of the remaining derivative liability of $167,131.

During the fiscal years ended December 31, 2011 and 2010, the Company issued 35,892 and 28,796, respectively, options to contractors with a Canadian dollar denominated strike price. Consequently, the Company had derivatives relating to these options since the strike price is denominated in a currency other than the US dollar functional currency of the Company. While there is an exception to this rule for employees in ASU 2010-13 "Compensation-Stock Compensation (Topic 718): Effect of Denominating the exercise price of a share-based payment award in the currency of the market in which the underlying equity security trades", no such exception exists for contractors. These options were marked to market until the earlier of their expiry or exercise. All Canadian denominated options issued to contractors fully vested at issuance and were to expire seven years from date of issuance. The fair value of these options at December 31, 2018 and December 31, 2017 was $0 and $

167,131

, respectively. The unrealized gain for these options for the year ended December 31, 2018 was $167,131. There was a loss on these options for the year ended December 31, 2017 of $133,697.

The following is a summary of Canadian denominated contractor option activity for the year ended December 31, 2018 and 2017.

Fair Value Disclosures [Abstract]

Fair Value Measurements

6.	Fair Value Measurements

The Company has adopted ASC 820 Fair Value Measurements and Disclosure Topic of the FASB. This Topic applies to certain assets and liabilities that are being measured and reported on a fair value basis. The Fair Value Measurements Topic defines fair value, establishes a framework for measuring fair value in accordance with US GAAP, and expands disclosure about fair value measurements. This Topic enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. The Topic requires that financial assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Oregon Health & Science University Agreement

On February 20, 2013, Fennec entered into a new exclusive license agreement with OHSU for exclusive worldwide license rights to intellectual property directed to thiol-based compounds, including STS and their use in oncology (the "New OHSU Agreement"). OHSU will receive certain milestone payments, royalty on net sales for licensed products and a royalty on any consideration received from sublicensing of the licensed technology.

The term of the New OHSU Agreement expires on the date of the last to expire claim(s) covered in the patents licensed to Fennec, unless earlier terminated as provided in the agreement. The New OHSU Agreement is terminable by either Fennec or OHSU in the event of a material breach of the agreement by either party after 45 days prior written notice. Fennec also has the right to terminate the New OHSU Agreement at any time upon 60 days prior written notice and payment of all fees due to OHSU under the New OHSU Agreement.

On May 18, 2015, Fennec negotiated an amendment ("Amendment 1") to the exclusive license agreement with OHSU. Amendment 1 expands the exclusive license agreement signed with OHSU on February 20, 2013 ("OHSU Agreement") to include the use of N-acetylcysteine as a standalone therapy and/or in combination with STS for the prevention of ototoxicity induced by chemotherapeutic agents to treat cancers. Further, Amendment 1 adjusts select milestone payments entered in the OHSU Agreement including but not limited to the royalty rate on net sales for licensed products, royalty rate from sublicensing of the licensed technology and the fee payable upon the regulatory approval of a licensed product.

The term of Amendment 1 under the OHSU Agreement expires on the date of the last to expire claim(s) covered in the patents licensed to Fennec or 8 years, whichever is later. In the event a licensed product obtains regulatory approval and is covered by the Orphan Drug Designation, the parties will in good faith amend the term of the agreement. STS is currently protected by methods of use patents that the Company exclusively licensed from OHSU that expire in Europe in 2021 and are currently pending in the United States. The New OHSU Agreement is terminable by either Fennec or OHSU in the event of a material breach of the agreement by either party after 45 days prior written notice. Fennec also has the right to terminate the New OHSU Agreement at any time upon 60 days prior written notice and payment of all fees due to OHSU under the New OHSU Agreement.

Executive Severance

In the event of his termination with us other than for cause, we will be obligated to pay Mr. Raykov a one-time severance payment equal to twelve months of salary (currently $350,000). In the event of his termination with us other than for cause, we will be obligated to pay Mr. Andrade a one-time severance payment equal to six months of salary (currently $125,000).

Subsequent Events

On February 1, 2019, the Company’s wholly owned subsidiary of Fennec Pharmaceuticals Inc. entered into a Loan and Security Agreement (the “Loan and Security Agreement”) with Bridge Bank, a division of Western Alliance Bank, an Arizona corporation (the “Bank”), pursuant to which the Bank agreed to loan $12.5 million to Fennec Pharmaceuticals, Inc., to be made available upon New Drug Application (“NDA”) approval of PEDMARK by no later than September 30, 2020. The proceeds from the loan will be used for working capital purposes and to fund general business requirements in accordance with the terms of the Loan and Security Agreement. Interest under the Term Loans shall bear interest, on the outstanding daily balance thereof, at a floating per annum rate equal to the Effective Interest Rate (as defined in the Loan and Security Agreement) which is equal to the sum of the Prime Rate published in the Wall Street Journal (currently 5.50%) plus one percent (1.00%). The debt facility is to have interest-only monthly payments due for the first eighteen months from the funding date and then monthly principal and interest payments are due through the remainder of the term which has a maturity date of October 1, 2023. In connection with the facility, Fennec has agreed to grant Bridge Bank a warrant to purchase up to 39,130 common shares at an exercise price of $6.80 per common share, for a term of ten years from the date of issuance, subject to early termination under certain conditions.

Management has evaluated subsequent events through March 15, 2019, the date the financial statements were available to be issued and there are no additional subsequent events that would require adjustment to or disclosure in the statements.

Tax Cuts and Jobs Act

On December 22, 2017, the United States government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and jobs Act (the “Tax Act”). The Tax Act reduces the corporate tax rate to 21%, effective January 1, 2018. The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB 118”) on December 23, 2017. SAB 118 provides a one-year measurement period from a registrant’s reporting period that includes the United States Tax Act’s enactment date to allow the registrant sufficient time to obtain, prepare and analyze information to complete the accounting required under ASC 740. The ultimate impact of the Tax Act on our reported results may differ from the estimates provided herein, possibly material, due to, among other things, changes in interpretations and assumptions we have made, guidance that may be issued, and other actions we may take as a result of the Tax Act different from presently contemplated.

There are no current income taxes owed, nor are any income taxes expected to be owed in the near term. At December 31, 2018 the Company has unclaimed Scientific Research and Experimental Development ("SR&ED") expenditures, income tax loss carry-forwards and non-refundable investment tax credits.
