Accounting Policies [Abstract]

Summary of significant accounting policies

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of expenses during the reporting periods. Actual results could differ from those estimates.

Comprehensive loss

The Company displays comprehensive loss and its components as part of its consolidated financial statements. Comprehensive loss consists of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes foreign currency translation adjustments.

Foreign currency translation

The functional currency of the Parent is the US Dollar. The functional currency of the Canadian Subsidiary is the Canadian Dollar (C$), and the functional currency of the Panama, US, Indiana, and Brazil Subsidiaries is the US Dollar. For the Canadian Subsidiary, assets and liabilities are translated at the exchange rates in effect at the balance sheet date, equity accounts are translated at the historical exchange rate, and the income statement accounts are translated at the average rate for each period during the year. Net translation gains or losses are adjusted directly to a separate component of other comprehensive income (loss) within stockholders’ equity (deficit).

Cash equivalents

The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash equivalents consist primarily of business savings accounts.

Short-term investments

The Company considers all liquid investments with maturities greater than three months but less than one year when purchased to be short-term investments. The Company has a six-month certificate of deposit at December 31, 2018 and 2017. It is renewable semi-annually in January and July.

Inventories

The Company measures inventory at the lower of cost or net realizable value (NRV), where NRV is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company also considers capacity utilization in calculating its inventory value with any excess capacity charged to general and administrative expenses.

Intangible assets

Definite-lived intangible assets include patents and licenses. Patent costs consist primarily of legal and filing fees incurred to file patents on proprietary technology developed by the Company. Patent costs are amortized on a straight-line basis over 20 years beginning with the filing date of the applicable patent. License fees are capitalized and expensed over the term of the licensing agreement.

Indefinite-lived intangible assets include trademark costs, which are capitalized with no amortization as they have an indefinite life.

Property, plant and equipment

Property, plant and equipment are carried at cost, and depreciation expense commences when the asset is placed into service, which may include receiving applicable regulatory approval. The Company depreciates all asset classes over their estimated useful lives, as follows:



Building	20 - 25 years
Equipment	7 - 10 years
Office furniture and equipment	3 years
Leasehold improvements	shorter of asset life or lease term
Vehicles	3 years

Impairment of long-lived assets

The Company reviews the carrying value of its long-lived tangible assets and definite-lived intangible assets on an annual basis or more frequently if facts and circumstances suggest that they may be impaired. The carrying values of such assets are considered impaired when the anticipated identifiable undiscounted cash flows from such assets are less than their carrying values. An impairment loss, if any, is recognized in the amount of the difference between the carrying amount and fair value.

Indefinite-lived intangible assets are subject to impairment testing annually or more frequently if impairment indicators arise. The Company’s impairment testing utilizes a discounted cash flow analysis that requires significant management judgment with respect to revenue and expense growth rates, changes in working capital, and the selection and use of the appropriate discount rate. An impairment loss is recognized in the amount of the difference between the carrying amount and fair value.

Revenue recognition

The Company records revenue on the sale of a product when all revenue recognition criteria are fulfilled, including identifying the contract with a customer; identifying the performance obligations in the contract; determining the transaction price; allocating the transaction price to the performance obligations in the contract; and recognizing revenue when (or as) the Company satisfies a performance obligation. In addition, collectability is assessed before applying the revenue recognition criteria. The Company evaluates customer credit risk in order to conclude it is “probable” it will collect the amount of consideration due in exchange for the goods or services.

Income taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences reverse. A valuation allowance is established to reduce net deferred tax assets to the amount expected to be realized. The Company follows accounting guidance regarding the recognition, measurement, presentation, and disclosure of uncertain tax positions in the financial statements. Tax positions taken or expected to be taken in the course of preparing the Company’s tax returns are required to be evaluated to determine whether the tax positions are “more likely than not” to be upheld under regulatory review. The resulting tax impact of these tax positions is recognized in the financial statements based on the results of this evaluation. The Company did not recognize any tax liabilities associated with uncertain tax positions, nor has it recognized any interest or penalties related to unrecognized tax positions. Generally, the Company is no longer subject to federal and state tax examinations by tax authorities for years before 2015.

Net loss per share

Basic and diluted net loss per share available to common stockholders has been calculated by dividing net loss attributable to common shareholders by the weighted average number of common shares outstanding during the year. Basic net loss per share is based solely on the number of common shares outstanding during the year. Fully diluted net loss per share includes the number of shares of common stock issuable upon the exercise of warrants and options with an exercise price less than the fair value of the common stock. Since the Company is reporting a net loss for all periods presented, all potential common shares are considered anti-dilutive and are excluded from the calculation of diluted net loss per share.

Share-based compensation

The Company measures and recognizes all share-based payment awards, including stock options made to employees and Directors, based on estimated fair values. The fair value of a share-based payment award is estimated on the date of grant using an option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s consolidated statement of operations. The Company uses the Black-Scholes option pricing model (“Black-Scholes”) as its method of valuation. Non-employee stock-based compensation is accounted for using Black-Scholes to determine the fair value of warrants or options awarded to non-employees with the fair value of such issuances expensed over the period of service.

Income Tax Disclosure [Abstract]

Income taxes

The components of loss before income taxes for the years ended December 31, 2018, 2017, and 2016, are presented below:



	2018			2017			2016
Domestic	$	(9,702,869	)	$	(6,526,706	)	$	(5,950,862	)

Loss before income taxes	$	(10,382,059	)	$	(9,258,647	)	$	(8,470,661	)

Income taxes computed using the federal statutory income tax rate differs from the Company’s effective tax rate for the years ended December 31, 2018, 2017, and 2016, primarily due to the following:



	2018			2017			2016

Total income tax	$	—		$	—		$	—

Included in Other for 2018 are $0.4 million related to state tax rate changes and $0.6 million related to foreign currency changes.

As of December 31, 2018, the Company has domestic net operating loss carryforwards of approximately $37.8 million, after consideration of limitations pursuant to section 382, to offset future federal taxable income, which begin to expire in 2031. The future utilization of certain historic net operating loss and tax credit carryforwards, however, is subject to annual use limitations based on the change in stock ownership rules of Internal Revenue Code Sections 382 and 383. The Company experienced a change in ownership under these rules during 2012 and revised its calculation of net operating loss carryforwards based on annual limitation rules. The Company also has foreign net operating loss carryforwards and research loss carryforwards totaling approximately $14.0 million and foreign research and development expense tax credits of approximately $2.6 million at December 31, 2018, which expire at various times commencing in 2019. Since the Company has incurred only losses from inception and there is uncertainty related to the ultimate use of the loss carryforwards and tax credits, a valuation allowance has been recognized to offset the Company’s deferred tax assets, and no benefit for income taxes has been recorded.

Significant components of the Company’s deferred tax assets and liabilities are as follows:



	2018			2017
Deferred tax assets:
Net operating loss carryforwards	$	14,120,607		$	12,411,425
Foreign research and development tax credit carryforwards	2,628,190			2,832,340
Property and equipment	463,343			482,161
Other	19,695			13,627
Total deferred tax assets	$	17,231,835		$	15,739,553
Valuation allowance	$	(17,231,835	)	$	(15,739,553	)
Net deferred tax assets	$	—		$	—

The valuation allowance increased by $1.5 million during 2018 and increased by $131,147 during 2017. The increase in 2018 is primarily due to increases in net operating loss carryforwards.

The increase in 2017 was primarily due to increases in foreign research and development tax credits and property and equipment, partially offset by a reduction in the U.S. deferred tax assets resulting from the impact of U.S. tax reform.

In 2016, the Parent obtained approval from Health Canada for the sale and consumption of its AquAdvantage Salmon product in Canada. Previously, in 2013, the Parent obtained approval from Environment Canada for the production of the product. AQUA Bounty Canada Inc. (the “Canadian Subsidiary”) was incorporated in January 1994 for the purpose of establishing a commercial biotechnology laboratory to conduct research and development programs related to the Parent’s technologies and to commercialize the Parent’s products in Canada. AquaBounty Panama, S. de R.L. (the “Panama Subsidiary”) was incorporated in May 2008 in Panama for the purpose of conducting commercial trials of the Parent’s products. AquaBounty Farms, Inc. (the “U.S. Subsidiary”) was incorporated in December 2014 in the State of Delaware for the purpose of conducting field trials and commercializing the Parent’s products in the United States. AquaBounty Farms Indiana LLC (the “Indiana Subsidiary”), which is wholly owned by the U.S. Subsidiary, was formed in June 2017 in the State of Delaware for the purpose of operating its aquaculture facility in Albany, Indiana. AquaBounty Brasil Participações Ltda. (the “Brazil Subsidiary”) was incorporated in May 2015 for the purpose of conducting field trials and commercializing the Parent’s products in Brazil. Basis of presentation The consolidated financial statements include the accounts of AquaBounty Technologies, Inc. and its wholly owned direct subsidiaries, AQUA Bounty Canada Inc.; AquaBounty Panama, S. de R.L.; AquaBounty Farms, Inc.; AquaBounty Farms Indiana LLC; and AquaBounty Brasil Participacoes Ltda. The entities are collectively referred to herein as the “Company.” All inter-company transactions and balances have been eliminated upon consolidation. Going Concern Uncertainty and Management's Plan The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced net losses and negative cash flows from operations since its inception and has cumulative losses attributable to common stockholders of $119 million as of December 31, 2018. At December 31, 2018, the Company had limited capital to fund its operations. This raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the accompanying consolidated financial statements are issued. The Company plans to raise capital through equity and/or debt financings. There is no assurance, however, that the Company will be successful in raising the needed capital and, if funding is available, that it will be available on terms acceptable to the Company. The Company may also cut operating costs or delay capital spend in order to preserve available cash. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of the above uncertainty.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidations

The unaudited interim consolidated financial statements include the accounts of AquaBounty Technologies, Inc. and its wholly owned direct subsidiaries, AQUA Bounty Canada Inc.; AquaBounty Panama, S. de R.L.; AquaBounty Farms, Inc.; AquaBounty Farms Indiana LLC; and AquaBounty Brasil Participações Ltda. All inter-company transactions and balances have been eliminated upon consolidation.

The consolidated financial statements include the accounts of AquaBounty Technologies, Inc. and its wholly owned direct subsidiaries, AQUA Bounty Canada Inc.; AquaBounty Panama, S. de R.L.; AquaBounty Farms, Inc.; AquaBounty Farms Indiana LLC; and AquaBounty Brasil Participacoes Ltda. The entities are collectively referred to herein as the “Company.” All inter-company transactions and balances have been eliminated upon consolidation.

Basis of accounting

The unaudited interim consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) consistent with those applied in, and should be read in conjunction with, the Company’s audited financial statements and related footnotes for the year ended December 31, 2018. The unaudited interim consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the Company’s financial position as of September 30, 2019, and its results of operations and cash flows for the interim periods presented and are not necessarily indicative of results for subsequent interim periods or for the full year. The unaudited interim consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements, as allowed by the relevant SEC rules and regulations; however, the Company believes that its disclosures are adequate to ensure that the information presented is not misleading.

Use of estimates

Comprehensive loss

Foreign currency translations

Cash equivalents

The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash equivalents consist primarily of business savings accounts.

Short-term investment

Inventories

Intangible assets

Indefinite-lived intangible assets include trademark costs, which are capitalized with no amortization as they have an indefinite life.

Property, plant and equipment



Building	20 - 25 years
Equipment	7 - 10 years
Office furniture and equipment	3 years
Leasehold improvements	shorter of asset life or lease term
Vehicles	3 years

Impairment of long-lived assets

Revenue recognition

Income taxes

Net loss per share

Basic and diluted net loss per share available to common stockholders has been calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Basic net loss is based solely on the number of Common Shares outstanding during the period. Fully diluted net loss per share includes the number of shares of common stock issuable upon the exercise of warrants and options with an exercise price less than the fair value of the common stock. Since the Company is reporting a net loss for all periods presented, all potential common shares are considered anti‑dilutive and are excluded from the calculation of diluted net loss per share.

Share-based compensation

Recently issued accounting standards

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016‑02, “Leases,” which requires a lessee to recognize lease liabilities for the lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and right-of-use assets, representing the lessee’s right to use, or control the use of, specified assets for the lease term. The ASU is effective for fiscal years beginning after December 15, 2018.

The Company adopted FASB ASU 2016-02 for lease accounting on January 1, 2019 and recognized a lease liability of $532 thousand and a corresponding right-of-use asset of $512 thousand. Management calculated the lease liability based on the net present value of the remaining lease payments on the date of adoption using a weighted average discount rate of 8%. As most of the Company’s leases did not provide an implicit interest rate, management used an estimated incremental borrowing rate. The adoption did not result in any cumulative-effect adjustment to beginning retained earnings.

The Company leases certain facilities, property, and equipment under noncancelable operating leases. A determination is made if an arrangement is a lease at its inception, and leases with an initial term of twelve months or less are not recorded on the balance sheet.

Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. For operating leases, expense is recognized on a straight-line basis over the lease term.

The Company has agreements with lease (e.g., minimum rent payments) and non-lease components (e.g., maintenance), which are generally accounted for separately. The Company has not elected the practical expedient to account for lease and non-lease components as one lease component.

Management does not expect any recently issued, but not yet effective, accounting standards to have a material effect on its results of operations or financial condition.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

Stockholders’ equity

In May 2018, the Company’s shareholders approved a reduction in the number of authorized shares from 240 million to 55 million shares of stock, of which 5 million are authorized as preferred stock and 50 million as common stock.

In December 2016, the shareholders approved a reverse share split ratio of 1-for-30 to be implemented on January 5, 2017. All share balances in the Financial Statements and accompanying notes have been restated to reflect this change.

Common stock

The holders of the common stock are entitled to one vote for each share held at all meetings of stockholders. Dividends and distribution of assets of the Company in the event of liquidation are subject to the preferential rights of any outstanding preferred shares. At December 31, 2018, the Company had reserved 339,964 shares of common stock for the exercise of options and 1,745,868 shares of common stock for the exercise of warrants.

Recent issuances

In January 2017, the Company closed an equity subscription of $25 million with Intrexon for 2,421,073 common shares at a price of $10.326.

In January 2018, the Company completed a public offering of 3,692,307 Common Shares and warrants for 4,246,153 Common Shares. Net proceeds to the Company were $10.6 million after deducting discounts, fees, and expenses. Intrexon Corporation, the Company’s majority shareholder, participated in the offering, purchasing 1,538,461 Common Shares and warrants for 1,538,461 Common Shares for gross proceeds of $5.0 million.

On October 24, 2018, 2,250,461 Common Shares were issued through the exercise of outstanding warrants at a discounted price of $2.00. Net proceeds to the Company were $4.3 million after deducting discounts, fees, and expenses. Intrexon participated in the exercise, converting warrants for the issuance of 1,538,461 Common Shares, resulting in gross proceeds of $3.1 million.

Additionally during 2018, the Company issued 249,824 Common Shares in conjunction with the exercise of warrants, with total proceeds of $0.8 million.

Warrants

In connection with the public offering of Common Shares that was completed in January 2018, the Company issued warrants to purchase 4,246,153 Common Shares. Each warrant has an exercise price per share of $3.25, is immediately exercisable, and will expire five years from the date of issuance. During 2018 249,824 warrants were exercised at $3.25 and the Board approved the exercise of 2,250,461 warrants in October 2018 at a discounted price of $2.00. The intrinsic value of the warrants that were converted at the discounted price was $1.8 million. The warrant inducement was treated as an extinguishment of an equity contract, as the warrant holders had to exercise their warrants in order to take advantage of the discounted conversion price. In accounting for the transaction the Company analogized to guidance regarding the treatment of preferred stock extinguishments and recognized the intrinsic value of the inducement, totaling $1.8 million, as a return of capital and as an addition to net loss for the purpose of calculating basic and diluted earnings per share.

The following table summarizes information about outstanding warrants at December 31, 2018:

	Number of options		Weighted average exercise price
Outstanding at December 31, 2017	227,203		$	9.39
Issued	113,561		2.50
Expired	(800	)	9.90
Outstanding at December 31, 2018	339,964		$	7.09
Exercisable at December 31, 2018	303,986		$	6.94

The weighted average fair value of stock options granted during 2018 was $2.50 (2017: $4.55; 2016: $4.46). There were no options exercised in 2018. The total intrinsic value of options exercised in 2017 was $43,420 (2016: $6,338). At December 31, 2018, the total intrinsic value of all options outstanding was $0 (2017: $17,454; 2016: $602,773), the total intrinsic value of exercisable options was $0 (2017: $17,454; 2016 $597,872), and the total number of shares available for grant under the 2016 Plan was 268,138 (2017: 397,500; 2016: 450,000).

The following table summarizes information about options outstanding and exercisable at December 31, 2018:



Weighted average exercise price of outstanding options	Number of options outstanding	Weighted average remaining estimated life (in years)	Number of options exercisable	Weighted average price of outstanding and exercisable options
$2.50 - $5.70	204,034	5.6	185,985
$6.90 - $9.60	53,175	3.7	53,175
$10.50 - $10.80	4,000	5.1	4,000
$14.20 - $23.40	78,755	7.2	60,826
	339,964		303,986	$6.94



	2018	2017	2016
Expected volatility	81%	78%	53%
Risk free interest rate	2.60%	1.80%	1.31%
Expected dividend yield	0.0%	0.0%	0.0%
Expected life (in years)	5	5	5

The risk-free interest rate is estimated using the Federal Funds interest rate for a period that is commensurate with the expected term of the awards. The expected dividend yield is zero because the Company has never paid a dividend and does not expect to do so for the foreseeable future. The expected life was based on a number of factors including historical experience, vesting provisions, exercise price relative to market price, and expected volatility. The Company believes that all groups of employees demonstrate similar exercise and post-vesting termination behavior and, therefore, does not stratify employees into multiple groups and forfeitures are recognized as they occur. The expected volatility was estimated using the Company’s historical price volatility over a period that is commensurate with the expected term of the awards.

Total share-based compensation on stock-option grants amounted to $236,098 in 2018 (2017: $95,734; 2016: $200,224). At December 31, 2018, the balance of unearned share-based compensation to be expensed in future periods related to unvested share-based awards is $111,243. The period over which the unearned share-based compensation is expected to be earned is 1.2 years.

Recently Issued Accounting Standards	Dec. 31, 2018
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently issued accounting pronouncements that may be relevant to the Company are the following: In February 2016, the FASB issued ASU 2016-02, “Leases,” which requires a lessee to recognize lease liabilities for the lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and right-of-use assets, representing the lessee’s right to use, or control the use of, specified assets for the lease term. Additionally, the new guidance has simplified accounting for sale and leaseback transactions. Lessor accounting is largely unchanged. The ASU is effective for fiscal years beginning after December 15, 2018. We will adopt the ASU effective January 1, 2019 and based on our current portfolio of leases, approximately $532 thousand of lease assets and liabilities will be recognized on our balance sheet, primarily relating to real estate. Management does not expect any other recently issued, but not yet effective, accounting standards to have a material effect on its results of operations or financial condition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The unaudited interim consolidated financial statements include the accounts of AquaBounty Technologies, Inc. and its wholly owned direct subsidiaries, AQUA Bounty Canada Inc.; AquaBounty Panama, S. de R.L.; AquaBounty Farms, Inc.; AquaBounty Farms Indiana LLC; and AquaBounty Brasil Participações Ltda. All inter-company transactions and balances have been eliminated upon consolidation. The unaudited interim consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) consistent with those applied in, and should be read in conjunction with, the Company’s audited financial statements and related footnotes for the year ended December 31, 2018. The unaudited interim consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the Company’s financial position as of September 30, 2019, and its results of operations and cash flows for the interim periods presented and are not necessarily indicative of results for subsequent interim periods or for the full year. The unaudited interim consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements, as allowed by the relevant SEC rules and regulations; however, the Company believes that its disclosures are adequate to ensure that the information presented is not misleading. Going Concern Uncertainty and Management’s Plan The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. In the Company’s Annual Report on Form 10‑K for December 31, 2018, management stated that there was substantial doubt about the Company’s ability to continue as a going concern due to its limited capital resources, and the Company’s independent registered public accounting firm emphasized this matter in its report to the shareholders and the Board of Directors. At that time, management prepared a plan to mitigate this doubt, which included an equity raise that subsequently provided the Company with $12.4 million of net new funds in 2019. At September 30, 2019, the Company’s cash balance totaled $6.4 million. Management has evaluated the Company’s cash resources in view of its planned spending for ongoing operations, capital expenditures, and working capital for the next twelve months from the filing date and has determined that its current funds will be exhausted by June 30, 2020. As a result, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that these financial statements are issued. To mitigate this doubt, management plans to seek additional financing in the form of equity or debt, partnerships, or other non-dilutive transactions to fund the Company’s cash requirements. However, the Company may not be able to raise additional financing or to do so at terms that are acceptable. In this event, management has the ability to reduce expenditures, slow down or delay capital spending, and divest assets in order to ensure its cash will extend through the next twelve months. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of the above uncertainty. Net loss per share Basic and diluted net loss per share available to common stockholders has been calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Basic net loss is based solely on the number of Common Shares outstanding during the period. Fully diluted net loss per share includes the number of shares of common stock issuable upon the exercise of warrants and options with an exercise price less than the fair value of the common stock. Since the Company is reporting a net loss for all periods presented, all potential common shares are considered anti‑dilutive and are excluded from the calculation of diluted net loss per share. Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016‑02, “Leases,” which requires a lessee to recognize lease liabilities for the lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and right-of-use assets, representing the lessee’s right to use, or control the use of, specified assets for the lease term. The ASU is effective for fiscal years beginning after December 15, 2018. The Company adopted FASB ASU 2016-02 for lease accounting on January 1, 2019 and recognized a lease liability of $532 thousand and a corresponding right-of-use asset of $512 thousand. Management calculated the lease liability based on the net present value of the remaining lease payments on the date of adoption using a weighted average discount rate of 8%. As most of the Company’s leases did not provide an implicit interest rate, management used an estimated incremental borrowing rate. The adoption did not result in any cumulative-effect adjustment to beginning retained earnings. The Company leases certain facilities, property, and equipment under noncancelable operating leases. A determination is made if an arrangement is a lease at its inception, and leases with an initial term of twelve months or less are not recorded on the balance sheet. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. For operating leases, expense is recognized on a straight-line basis over the lease term. The Company has agreements with lease (e.g., minimum rent payments) and non-lease components (e.g., maintenance), which are generally accounted for separately. The Company has not elected the practical expedient to account for lease and non-lease components as one lease component. Management does not expect any recently issued, but not yet effective, accounting standards to have a material effect on its results of operations or financial condition.

Risks and Uncertainties [Abstract]
Risks and uncertainties	Risks and uncertainties The Company is subject to risks and uncertainties common in the biotechnology and aquaculture industries. Such risks and uncertainties include, but are not limited to: (i) results from current and planned product development studies and trials; (ii) decisions made by the FDA or similar regulatory bodies in other countries with respect to approval and commercial sale of any of the Company’s proposed products; (iii) the commercial acceptance of any products approved for sale and the Company’s ability to manufacture, distribute, and sell for a profit any products approved for sale; (iv) the Company’s ability to obtain the necessary patents and proprietary rights to effectively protect its technologies; and (v) the outcome of any collaborations or alliances entered into by the Company. In addition, as disclosed in “Item 1A. Risk Factors,” below, and in “Item 1A. Risk Factors” in our Annual Report on Form 10‑K for the year ended December 31, 2018, which was filed on March 7, 2019, there are a number of other risks and uncertainties that may have a material effect on the operating results of our business and our financial condition. Concentration of credit risk Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents and certificates of deposit. This risk is minimized by the Company’s policy of investing in financial instruments with short-term maturities issued by highly rated financial institutions. The Company’s cash balances may at times exceed insurance limitations. The Company holds cash balances in bank accounts located in Canada to fund its local operations. These amounts are subject to foreign currency exchange risk, which is mitigated by the Company’s policy to limit the balances held in these accounts. Balances in Canadian bank accounts totaled $242,324 at September 30, 2019.

Balances in Canadian bank accounts totaled $230,677 at December 31, 2018. Financial instruments The carrying amounts reported in the consolidated balance sheets for other receivables and accounts payable approximate fair value based on the short-term maturity of these instruments. The carrying value of term debt approximates its fair value since it provides for market terms and interest rates. Included in other assets is a long-term investment that consists of 216,281 shares of common stock of A/F Protein, Inc. (AFP), equating to less than 1% ownership, with a cost basis of $21,628, which the Company believes to be the best estimate of market value. AFP and the Company have certain shareholders in common.
