Note 2.   Summary of Significant Accounting Policies

In the opinion of management, the accompanying balance sheet and related statements of operations, cash flows, and stockholders’ deficit include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and partially-owned subsidiaries BLEST and Clyra Medical. All intercompany accounts and transactions have been eliminated.

Foreign Currency

The Company has designated the functional currency of BioLargo Water, Inc., our Canadian subsidiary, to be the Canadian dollar. Therefore, translation gains and losses resulting from differences in exchange rates are recorded in accumulated other comprehensive income.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less when acquired to be cash equivalents. Substantially all cash equivalents are held in short-term money market accounts at one of the largest financial institutions in the United States. From time to time, our cash account balances are greater than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner per bank, and during such times, we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the financial institution. We do not anticipate non-performance by our financial institution.

As of September 30, 2022 and December 31, 2021, our cash balances were made up of the following (in thousands):

	September 30, 2022		December 31, 2021
BioLargo, Inc. and subsidiaries	$	1,251	$	941
Clyra Medical Technologies, Inc.		17		21
Total	$	1,268	$	962

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts as of  September 30, 2022 was $12,000 and at December 31, 2021, was $12,000.

Credit Concentration

We had a limited number of customers that account for significant portions of our revenue. During the nine months ended September 30, 2022 and 2021, we had the following customers that accounted for more than 10% of consolidated revenues, as follows:

	September 30, 2022			September 30, 2021
Customer A		44	%		<10	%
Customer B		14	%		<10	%
Customer C		<10	%		12	%
Customer D		<10	%		14	%
Customer E		<10	%		11	%

We had a limited number of customers that accounted for more than 10% of consolidated accounts receivable at September 30, 2022, and at December 31, 2021, as follows:

	September 30, 2022			December 31, 2021
Customer A		13	%		<10	%
Customer B		15	%		<10	%
Customer F		11	%		<10	%
Customer G		<10	%		32	%
Customer H		<10	%		12	%

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. The allowance for obsolete inventory as of  September 30, 2022, and December 31, 2021, was $3,000. Inventories consisted of (in thousands):

	September 30, 2022		December 31, 2021
Raw material	$	123	$	108
Finished goods		137		103
Total	$	260	$	241

Other Non-Current Assets

	September 30, 2022		December 31, 2021
Patents	$	34	$	34
Security deposits		35		35
Tax credit receivable		54	$	-
Total	$	123	$	69

Equity Method of Accounting

On March 20, 2020, we invested $100,000 into a South Korean entity (Odin Co. Ltd., “Odin”) pursuant to a Joint Venture agreement we had entered into with BKT Co. Ltd. and its U.S. subsidiary, Tomorrow Water. We received a 40% non-dilutive equity interest, and BKT and Tomorrow Water each received 30% equity interests for an aggregate $150,000 investment.

We account for our investment in the joint venture under the equity method of accounting. We have determined that while we have significant influence over the joint venture through our technology license and our position on the Board of Directors, we do not control the joint venture or are otherwise involved in managing the entity and we own less than a majority of the equity. Therefore, we record the asset on our consolidated balance sheet and record an increase or decrease the recorded balance by our percentage ownership of the profits or losses in the joint venture. The joint venture incurred a loss during the nine months ended September 30, 2022 and 2021, our 40% ownership share reduced our investment interest by $15,000 and $23,000, respectively.

Impairment

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset  may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. For the nine months ended September 30, 2022 and 2021, management determined that there was no impairment of its long-lived assets, including its patents.

Nevertheless, during the three months ended  December 31, 2021, management determined that there was an impairment expense related to the sale back to Scion Solutions, LLC (“Scion’) of certain intellectual property, recorded on our balance sheet as “In-Process Research and Development” and an impairment of Clyra’s prepaid marketing. Total impairment expense for 2021 was $342,000.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the three and nine months ended September 30, 2022 and 2021, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

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 at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, debt transactions, derivative liabilities, allowance for bad debt, asset depreciation and amortization, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-Based Compensation Expense

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Fair value is determined on the grant date. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model.

For stock and stock options issued to consultants and other non-employees for services, the Company measures and records an expense as of the earlier of the date at which either: a commitment for performance by the non-employee has been reached or the non-employee’s performance is complete. The equity instruments are measured at the current fair value, and for stock options, the instruments are measured at fair value using the Black Scholes option model.

The following methodology and assumptions were used to calculate share-based compensation for the nine months ended September 30, 2022 and 2021:

	2022						2021
	Non Plan			2018 Plan			Non Plan			2018 Plan
Risk free interest rate	2.32	–	3.83%	2.32	–	3.83%		1.73	%	0.93	–	1.73%
Expected volatility	115	–	117%	115	–	117%		124	%	121	–	124%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Life in years		10			10			10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future.

Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Warrants

Warrants issued with our convertible promissory notes, note payables, line of credit are accounted for under the fair value and relative fair value method.

The warrant is first analyzed per its terms as to whether it has derivative features or not. If the warrant is determined to be a derivative and not qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”).

If the warrant is determined to not have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

Convertible debt instruments are recorded at fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered, or product is received.

Revenue Recognition

We account for revenue in accordance with ASC 606, “Revenue from Contacts with Customers”. The guidance focuses on the core principle for revenue recognition, which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, the guidance provides that an entity should apply the following steps:

Step 1: Identify the contract(s) with a customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

We generate revenue through our subsidiaries. For the sale of goods, the subsidiary identifies its contract with the customer through a written purchase order, in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Revenue is recognized at a point in time when the order for its goods are shipped if its agreement with the customer is FOB manufacturer, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer’s purchase order. In association with certain product purchases, ONM Environmental installs misting systems for which it bills on a time and materials basis. It identifies its contract with the customer through a written purchase order in which the details of the time to be billed and materials purchased and an estimated completion date. The performance obligation is the completion of the installation, and at that time revenue is recognized.

For services, such as through our engineering group, the subsidiary identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. Service contracts typically call for invoicing for time and materials incurred for that contract, although some provide for milestone or fixed cost payments, where an agreed-to amount is invoiced per month for the life of the contract. In these instances, completed work, billed hourly, is recognized as revenue. If the billing amount is greater or lesser than the completed work, a contract receivable or contract liability is created. As of  September 30, 2022, we had $6,000 of contract liability. As of December 31, 2021, we had contract liability totaling $89,000. To date, there have been no discounts or other financing terms for the contracts.

Royalties or license fees from our intellectual property are based on the licensee’s sales of products incorporating or using our licensed intellectual property.

Government Grants

We have been awarded multiple research grants from the Canadian National Research Institute – Industrial Research Assistance Program (NRC-IRAP) and the National Science and Engineering Research Council of Canada (NSERC). The grants received are considered other income and are included in our consolidated statements of operations. We received our first grant in 2015 and have been awarded over 80 grants totaling over $3.7 million. Some of the funds from these grants are given directly to third parties (such as the University of Alberta or a third-party research scientist) to support research on our technology. The grants have terms generally ranging between nine and eighteen months and support a majority, but not all, of the related research budget costs. This cooperative research allows us to utilize (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

The grants typically provide for (i) recurring monthly amounts, (ii) reimbursement of costs for research talent for which we invoice to request payment, and (iii) ancillary cost reimbursement for research talent travel related costs. All awarded grants have specific requirements on how the money is spent, typically to employ researchers. None of the funds may be used for general administrative expenses or overhead in the United States. These grants have substantially increased our level of research and development activities in Canada. We continue to apply for Canadian government and agency grants to fund research and development activities. Not all of our grant applications have been awarded, and no assurance can be made that any pending grant application, or any future grant applications, will be awarded.

Income Taxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”).  Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date.  If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.  Management believes there are no unrecognized tax benefits or uncertain tax positions as of September 30, 2022, and December 31, 2021.

The Company assessed its earnings history, trends and estimates of future earnings and determined that the deferred tax asset could not be realized as of September 30, 2022. Accordingly, a valuation allowance was recorded against the net deferred tax asset.

The Company recognizes interest and penalties on income taxes as a component of income tax expense, should such an expense be realized.

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company’s financial instruments (excluding debt and equity instruments) as of September 30, 2022 and December 31, 2021, approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, lines of credit, and other assets and liabilities.

Tax Credits

Our research and development activities in Canada may entitle our Canadian subsidiary to claim benefits under the “Scientific Research and Experimental Development Program”, a Canadian federal tax incentive program designed to encourage Canadian businesses of all sizes and in all sectors to conduct research and development in Canada. Benefits under the program include credits to taxable income. If our Canadian subsidiary does not have taxable income in a reporting period, we instead receive a tax refund from the Canadian Revenue Authority. A refund has been submitted totaling $54,000, which is classified in Other Income on our Consolidated Statement of Operations and Comprehensive Loss.

Leases

In February 2016, the FASB issued ASU Update No. 2016-02, “Leases,” which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures are also required (see Note 10). We adopted this standard effective January 1, 2019 using the effective date option, as approved by the FASB in July 2018, which resulted in a $399,000 gross up of assets and liabilities; this balance may fluctuate over time as we enter into new leases, extend or terminate current leases. Upon the transition to ASC 842, the Company elected to use hindsight as a practical expedient with respect to determining the lease terms and in assessing any impairment of right-of-use assets for existing leases. No impairment is expected at this time. As of  September 30, 2022, the right of use assets on our balance sheet related to our operating leases totals $896,000.

Recent Accounting Pronouncements

In August 2020,the FASB issued Accounting Standards UpdateNo.2020-06,“Debt—Debt with Conversion and Other Options (Subtopic470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity”. For convertible instruments, the FASB decided to reduce the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that arenotclearly and closely related to the host contract, that meet the definition of a derivative, and that donotqualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. The FASB decided to amend the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. The FASB observed that the application of the derivatives scope exception guidance results in accounting for some contracts as derivatives while accounting for economically similar contracts as equity. The FASB also decided to improve and amend the related EPS guidance. The amendments in this Update are effective for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021,including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023,including interim periods within those fiscal years; early adoption is permitted. Management has evaluated this update and adopted it as of January 1, 2022. In do so, we evaluated the convertible debt issued by Clyra Medical during the three months ended June 30, 2022 (see Note 8), and determined that the beneficial conversion feature was fixed at the time of issuance and not an embedded derivative under Subtopic 815-15.  As a result of the early adoption, there are no other potential affects on the Company’s current financial statements.
