Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and partially owned subsidiaries BETI, 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, Bank of America. 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 June 30, 2023, and December 31, 2022, our cash balances were made up of the following (in thousands):

	June 30, 2023		December 31, 2022
BioLargo, Inc. and subsidiaries	$	2,762	$	1,681
Clyra Medical Technologies, Inc.		813		170
Total	$	3,575	$	1,851

Accounts Receivable

In June 2016, the FASB issued ASU 2016-13, which sets out the principles for the recognition of measurement of credit losses on financial instruments, including trade receivables. The standard eliminates the probable initial recognition threshold and requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. The new standard was effective for the Company beginning January 1, 2023 and primarily impacted trade accounts receivable. 

Accounts receivable are customer obligations that are unconditional. Accounts receivable are presented net of an allowance for doubtful accounts for expected credit losses, which represents an estimate of amounts that may not be collectible. The Company performs ongoing credit evaluations of its customers and, if necessary, provides an allowance for doubtful accounts and expected credit losses. A provision to the allowances for doubtful accounts for expected credit losses is recorded based on factors including the length of time the receivables are past due, the current business environment, and the Company’s historical experience. Provisions to the allowances for doubtful accounts for expected credit losses are recorded to general and administrative expenses. The Company writes off accounts receivable against the allowance when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. The Company does not have any off-balance-sheet credit exposure related to customers. As of June 30, 2023, and December 31, 2022, the allowance for doubtful accounts for expected credit losses was $58,000 and $12,000.

Credit Concentration

We have a limited number of customers that account for significant portions of our revenue. During the three and six months ended June 30, 2023, and 2022, the following customers accounted for more than 10% of consolidated revenues:

	Three Months						Six Months
	June 30, 2023			June 30, 2022			June 30, 2023			June 30, 2022
Customer A		55	%		39	%		77	%		35	%
Customer B	<10		%		27	%	<10		%		17	%
Customer C	<10		%	<10		%	<10		%		10	%

At June 30, 2023, one customer accounted for more than 10% of consolidated accounts receivable, and at December 31, 2022, three customers accounted for more than 10% of consolidated accounts receivable:

	June 30, 2023			December 31, 2022
Customer A		49	%		11	%
Customer B	<10		%		31	%
Customer D	<10		%		15	%

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  June 30, 2023, and December 31, 2022, was $212,000 and $158,000. Inventories consisted of (in thousands):

	June 30, 2023		December 31, 2022
Raw material	$	83	$	46
Finished goods		44		74
Total	$	127	$	120

Other Non-Current Assets

Other non-current assets consisted of (i) security deposits related to our business offices, (ii) three patents acquired on  October 22, 2021, for $34,000, and (iii) tax credit receivables from the Canadian government related to a research and development credit from our Canadian subsidiary for which we’ve applied for and received in prior periods.

	June 30, 2023		December 31, 2022
Patents	$	34	$	34
Security deposits		35		35
Tax credit receivable		--		55
Total	$	69	$	124

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. based 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 of the recorded balance by our percentage ownership of the profits or losses in the joint venture. The joint venture has incurred a loss since inception and our 40% ownership share reduced our investment interest. For the three and six months ended  June 30, 2023, the reduction of our investment interest totaled $6,000 and $12,000, respectively, and for the same periods in 2022, reduced our investment interest $8,000 and $15,000, 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. There were no impairment losses related to intangible assets during the three or six months ended June 30, 2023 or 2022.

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 convertible notes payable, stock options and warrants were exercised into common stock. For the three and six months ended June 30, 2023, and 2022, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the Company’s net loss which creates an anti-dilutive effect of the convertible notes payable, warrants and stock options.

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, impairment expense, 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 six months ended June 30, 2023, and 2022:

	2023						2022
	Non Plan			2018 Plan			Non Plan			2018 Plan
Risk free interest rate	3.48	–	3.58%	3.48	–	3.58%	2.32	–	3.83%	2.32	–	2.98%
Expected volatility	113	-	114%	113	-	114%	114	–	117%	116	–	117%
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. The 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.

Warrants

Warrants issued with our convertible and non-convertible debt instruments 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. The warrant relative fair values are also recorded as a discount to the convertible promissory notes.

Non-Cash Transactions

We determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock 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.

The Company’s products are sold through a contract with the customer and 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 goods are shipped if the agreement is FOB manufacturer, and when goods are delivered if FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer’s purchase order.

Service contracts are performed through a written contract, which specifies the performance obligations and the rate at which the services will be billed, typically by time and materials. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed, or, for services related to product installations, at the completion of the installation. A few contracts have called for milestone or fixed cost payments, where we invoice an agreed-to amount 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 receivable or payable is created. These accounts are adjusted upon additional billings as the work is completed. To date, there have been no discounts or other financing terms for the contracts.

The Company has outstanding contract liability obligations of $10,000 as of June 30, 2023, recorded as deferred revenue. We recognized $7,000 in revenue and reduced the deferred revenue balance by the same amount as performance obligations were satisfied in the six months ended June 30, 2023. The outstanding balance will be recognized over the remaining life of the contracts. Our Canadian subsidiary had a customer deposit outstanding at June 30, 2023, totaling $113,000, that was awarded as part of a grant for a particular project that has been delayed.

As we generate revenues from royalties or license fees from our intellectual property, a licensee will pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. We have entered into a licensing agreement for the CupriDyne Clean product, and we recognize royalty and license fees on a quarterly basis as the product is sold through to third parties and reported to us.

Government Grants

We have been awarded multiple research grants from the private and public Canadian research programs. The income we receive directly from grants is recorded as other income. We have been awarded over 80 grants since our first in 2015. 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 six 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 June 30, 2023, and December 31, 2022.

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 June 30, 2023, and December 31, 2022. Accordingly, a 100% 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 as of June 30, 2023, and December 31, 2022 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, line of credit, and other assets and liabilities. The carrying amount of debt instruments are believed to approximate fair value as the stated interest rates are reflective of the prevailing market rates.

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. Those refunds are classified in Other Income on our Consolidated Statement of Operations and Comprehensive Loss.

Leases

At inception of a lease contract, we assess whether the contract is, or contains, a lease. Our assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period of the contract, and (3) whether we have the right to direct the use of the asset during such time period. At inception of a lease, we allocate the consideration in the contract to each lease component based on its relative stand-alone price to determine the lease payments. Leases are classified as either finance leases or operating leases. A lease must be classified as a finance lease if any of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not meet any of these criteria. We have no leases classified as finance leases. As of June 30, 2023, the weighted average remaining lease term for our operating leases was nine years. The weighted average discount rate for our operating leases was 18%. For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease. The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, management estimates the incremental borrowing rate, which currently is estimated to be 18%. Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early. Lease components are included in the measurement of the initial lease liability. Additional payments based on a change in our portion of the operating expenses, including real estate taxes and insurance, are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability. Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term. We have elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less. The effect of short-term leases on our right-of-use asset and lease liability was not material.

As of June 30, 2023, the right-of-use assets totaled $807,000 and the lease liability totaled $818,000 on our balance sheet related to our operating leases.

Property and Equipment

Property and equipment includes machinery and leasehold improvements and is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 - 5 years or the remaining lease term. Newly built leaseholds, additions, renewals, and betterments that significantly extend the life of the asset are capitalized. The Company is currently constructing a facility and purchasing equipment for producing sodium sulfur batteries. Expenditures for repairs and maintenance are charged to expense as incurred. For assets sold or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the accounts, and any related gain or loss is reflected in income for the period.

Recent Accounting Pronouncements

Currently there are no recently released pronouncements that are considered applicable to the Company’s financial statements.
