Notes to Financial Statements
Business Description and Basis of Presentation [Text Block]	1 . Description of Business Liquidmetal Technologies, Inc. (the “Company”) is a materials technology company that develops and commercializes products made from amorphous alloys. The Company's family of alloys consists of a variety of bulk alloys and composites that utilize the advantages offered by amorphous alloys technology. The Company designs, develops, and sells products and custom parts from bulk amorphous alloys to customers in a wide range of industries. The Company also partners with third -party manufacturers and licensees to develop and commercialize Liquidmetal alloy products. Amorphous alloys are, in general, unique materials that are distinguished by their ability to retain a random atomic structure when they solidify, in contrast to the crystalline atomic structure that forms in other metals and alloys when they solidify. Liquidmetal alloys are proprietary amorphous alloys that possess a combination of performance, processing, and potential cost advantages that the Company believes will make them preferable to other materials in a variety of applications. The amorphous atomic structure of bulk alloys enables them to overcome certain performance limitations caused by inherent weaknesses in crystalline atomic structures, thus facilitating performance and processing characteristics superior in many ways to those of their crystalline counterparts. The Company believes that the alloys and the molding technologies it employs may result in components, for many applications, that exhibit: exceptional dimensional control and repeatability that rivals precision machining, excellent corrosion resistance, brilliant surface finish, high strength, high hardness, high elastic limit, alloys that are non-magnetic, and the ability to form complex shapes common to the injection molding of plastics. Interestingly, all of these characteristics are achievable from the molding process, so design engineers often do not have to select specific alloys to achieve one or more of the characteristics as is the case with crystalline materials. The Company believes these advantages could result in Liquidmetal alloys supplanting high-performance alloys, such as titanium and stainless steel, and other incumbent materials in a wide variety of applications. Moreover, the Company believes these advantages could enable the introduction of entirely new products and applications that are not possible or commercially viable with other materials. The Company's revenues are derived from i) selling bulk Liquidmetal alloy products to customers who produce medical devices, automotive assemblies, sports and leisure goods, and non-consumer electronic devices, ii) selling tooling and prototype parts such as demonstration parts and test samples for customers with products in development, iii) product licensing and royalty revenue, and iv) research and development revenue. The Company expects that these sources of revenue will continue to significantly change the character of the Company's revenue mix.

Notes to Financial Statements

Basis of Presentation and Significant Accounting Policies [Text Block]

. Summary of Significant Accounting Policies

Principles of Consolidation.

The consolidated financial statements include the accounts of Liquidmetal Technologies, Inc., its special-purpose wholly-owned subsidiary, Crucible Intellectual Property LLC,

20321

Valencia LLC, and Liquidmetal Golf. All intercompany balances and transactions have been eliminated.

Non-

ontrolling

nterest.

The results of operations attributable to the non-controlling interest of Liquidmetal Golf are presented within equity and are shown separately from the Company's equity.

Revenue Recognition

. Revenue is recognized pursuant to applicable accounting standards including FASB ASC Topic

606

(“ASC

606”

), Revenue from Contracts with Customers. ASC

606

summarizes certain points in applying generally accepted accounting principles to revenue recognition in financial statements and provides guidance on revenue recognition issues in the absence of authoritative literature addressing a specific arrangement or a specific industry.

Products

. Product revenues are primarily generated from the sale and prototyping of molds and bulk alloy products. Revenue is recognized when i) persuasive evidence of an arrangement exists, ii) delivery has occurred, iii) the sales price is fixed or determinable, iv) collection is probable and v) all obligations have been substantially performed pursuant to the terms of the arrangement. When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, it records deferred revenue, which represents a contract liability. The Company will recognize deferred revenue as products revenue after it has transferred control of the goods or services to the customer and all revenue recognition criteria are met. Such amounts are

not

expected to be material on an ongoing basis.

Licensing and royalties

. License revenue arrangements in general provide for the grant of an exclusive or non-exclusive right to manufacture and/or sell products covered by patented technologies owned or controlled by the Company. The intellectual property rights granted

may

be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined period of time. Licensing revenues that are

one

-time fees upon the granting of the license are recognized when i) the license term begins in a manner consistent with the nature of the transaction and the earnings process is complete, ii) when collectability is reasonably assured or upon receipt of an upfront fee, and iii) when all other revenue recognition criteria have been met. Pursuant to the terms of these agreements, the Company has

further obligation with respect to the grant of the license. Licensing revenues that are related to royalties are recognized as the royalties are earned over the related period.

Practical Expedients and Exemptions

. The Company generally expenses sales commissions when incurred because the amortization period would have been

one

year or less. These costs are recorded within selling, marketing, general and administrative expenses. The Company does

not

disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of

one

year or less and (ii) contracts for which the Company recognizes revenue at the amount for which it has the right to invoice for services performed.

Cash

and cash equivalents

The Company considers all highly-liquid investments with maturity dates of

three

months or less when purchased to be cash equivalents. The Company limits the amount of credit exposure to each individual financial institution and places its temporary cash into investments of high credit quality with a financial institution that exceeds federally insured limits. The Company has

not

experienced any losses related to these balances and believes its credit risk to be minimal. As of

December 31, 2020

and

2019,

the Company held deposits of

$1,328

and

$18,399,

respectively, in such highly-liquid investments.

Investments in debt securities

. The Company will invest excess funds to maximize investment yield, while maintaining liquidity and minimizing credit risk. Debt securities are carried at fair value and consist primarily of investments in obligations of the United States Treasury, various U.S. and foreign corporations, and certificates of deposits. The Company classifies its investments in debt securities as available-for-sale with all unrealized gains or losses included as part of other comprehensive income. The Company evaluates its debt securities with unrealized losses on a quarterly basis for potential other-than-temporary impairments in value. As a result of this assessment, the Company did

not

recognize any other-than-temporary impairment losses considered to be credit related for the years ended

December 31, 2020

and

2019.

Trade Accounts Receivable.

The Company grants credit to its customers generally in the form of short-term trade accounts receivable. The creditworthiness of customers is evaluated prior to signing a contract with the customer. As of

December 31, 2020,

one

customer represented

99%,

$270,

of the total outstanding trade accounts receivable. As of

December 31, 2019,

two

customers represented

90%,

$280,

of the total outstanding trade accounts receivable. During

2020,

there were

four

major customers, who together accounted for

93%

of total revenue. During

2019,

there were

five

major customers, who together accounted for

83%

of total revenue. In the future, the Company expects that a significant portion of the revenue

may

continue to be concentrated in a limited number of customers, even if the bulk alloys business grows.

The allowance for doubtful accounts reflects management's best estimate of probable losses inherent in the trade accounts receivable. Management primarily determines the allowance based on the aging of accounts receivable balances, historical write-off experience, customer concentrations, customer creditworthiness and current industry and economic trends. The Company's provisions for uncollectible receivables are included in selling, marketing, general and administrative expense in the consolidated statements of operations. At

December 31, 2020

and

2019,

the Company had recorded an allowance for doubtful accounts of

$234

and

$8,

respectively.

Inventory.

Inventory is stated at the lower of weighted-average cost or net realizable value. Inventory is recorded at actual cost when purchased and then expensed at weighted-average cost as used in production and/or shipped to satisfy customer orders. We perform an analysis of our inventory balances at least quarterly to determine if the carrying amount of inventories exceeds their net realizable value. The analysis of estimated net realizable value is based on customer orders, market trends and historical pricing. If the carrying amount exceeds the estimated net realizable value, the carrying amount is reduced to the estimated net realizable value.

Property and Equipment.

Property and equipment are stated at cost less accumulated depreciation and amortization. Additions and major renewals are capitalized. Repairs and maintenance are charged to expense as incurred. Upon disposal, the related cost and accumulated depreciation are removed from the accounts, with the resulting gain or loss included in operating income. Depreciation is provided principally on the straight-line method over the estimated useful lives of the assets, which range from

one

five

years.

Intangible Assets.

Intangible assets consist of the costs incurred to purchase patent rights and costs incurred to register and maintain patents and trademarks. Intangible assets are reported at cost, net of accumulated amortization. Patents and trademarks are amortized using the straight-line method over a period based on their contractual lives ranging from

ten

seventeen

years.

Impairment of Long-lived Assets

. The Company reviews long-lived assets to be held and used in operations for impairment whenever events or changes in circumstances indicate that the carrying value of an asset

may

be impaired. These evaluations

may

result from significant decreases in the overall market outlook for the Company's technology or the market price of an asset, a significant adverse change in the extent or manner in which an asset is being used in its physical condition, a significant adverse change in legal factors or in the business climate that could affect the value of an asset, as well as economic or operational analyses. If the Company concludes that the carrying value of certain assets will

not

be recovered based on expected undiscounted future cash flows, an impairment write-down is recorded to reduce the assets to their estimated fair value. Fair value is determined via market, cost and income based valuation techniques, as appropriate. The fair value is measured on a nonrecurring basis using a combination of quoted prices for similar assets in active markets and other unobservable adjustments to historical cost (Level

) inputs. Based on the results of this analysis, the Company recorded non-cash impairment charges of

$1,676

for the year ended

December 31, 2019,

primarily related to the carrying value of the Company's manufacturing assets that would

not

be utilized prospectively as a result of the

2019

Restructuring Plan.

such charges were recorded for the year ended

December 31, 2020.

Fair Value

Measurements.

The estimated fair values of financial instruments reported in the consolidated financial statements have been determined using available market information and valuation methodologies, as applicable. The fair value of cash and restricted cash approximate their carrying value due to their short maturities and are classified as Level

instruments within the fair value hierarchy.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value based upon the following fair value hierarchy:

Level

—

Quoted prices in active markets for identical assets or liabilities;

Level

—

Observable inputs other than Level

prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are

not

active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level

—

Unobservable inputs that are supported by little or

market activity and that are significant to the fair value of the assets or liabilities.

As of

December 31, 2020,

the following table represents the Company's fair value hierarchy for items that are required to be measured at fair value on a recurring basis:

	Fair Value		Level 1		Level 2		Level 3

Investments in debt securities (short-term)		14,720		8,939		5,781		-
Investments in debt securities (long-term)		12,768		-		12,768		-

As of

December 31, 2019,

the following table represents the Company's fair value hierarchy for items that are required to be measured at fair value on a recurring basis:

	Fair Value		Level 1		Level 2		Level 3

Investments in debt securities (short-term)		4,415		705		3,710		-
Investments in debt securities (long-term)		7,074		908		6,166		-

Non-recurring fair value measurements.

Certain assets and liabilities are measured at fair value on a nonrecurring basis. In other words, the instruments are

not

measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). As a result of the Company's periodic assessment of impairment of long-lived assets, the Company recorded an impairment loss of

$1,676

during the year ended

December 31, 2019.

such losses were recorded during the year ended

December 31, 2020.

Concentration Risk.

The Company currently sources substantially all of its product manufacturing from

one

manufacturer, namely Yihao. The Company's manufacturing and operating results could be adversely affected if the supply of products from Yihao were delayed or curtailed. While the Company expects this manufacturing relationship to continue, it is attempting to mitigate this risk by developing other suppliers of its products. For the year ended

December 31, 2020,

Yihao accounted for

77%

$478

of total cost of goods sold.

Research and Development Expenses.

Research and development expenses represent salaries, related benefits expense, expenses incurred for the design and testing of new processing methods and other expenses related to the research and development of Liquidmetal alloys. Development costs incurred in research and development activities are expensed as incurred.

Advertising and Promotion Expenses.

Advertising and promotion expenses are expensed when incurred. Advertising and promotion expenses were

$61

and

$68,

for the years ended

December 31, 2020

and

2019,

respectively.

Legal Costs.

Legal costs are expensed as incurred.

Stock-Based Compensation

. The Company accounts for share-based compensation in accordance with the fair value recognition provisions of FASB ASC Topic

718,

Share-based Payment

, which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the consolidated financial statements based on their fair values. The fair value of stock options is calculated by using the Black-Scholes option pricing formula that requires estimates for expected volatility, expected dividends, the risk-free interest rate and the term of the option. If any of the assumptions used in the Black-Scholes model change significantly, share-based compensation expense

may

differ materially in the future from that recorded in the current period.

Leases.

The Company leases its previous manufacturing facility under a long-term contract, which is accounted for as an operating lease. The lease provides for a fixed base rent and variable payments comprised of reimbursements for property taxes, insurance, utilities, and common area maintenance. The lease has a term of

sixty-two

months, exclusive of options to renew. In accordance with

ASC

842

Leases,

lease income, which includes escalating rents over the term of the lease, is recorded on a straight-line basis over the expected lease term. The difference between lease income and payments received is recorded as a rent receivable, which is included as part of other assets within the consolidated balance sheets. Amounts paid for broker commissions represent prepaid direct lease costs, and will be amortized as an off-set to lease income over the lease term.

Income Taxes.

Income taxes are provided under the asset and liability method as required by FASB ASC Topic

740,

Accounting for Income Taxes

. Under this method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. The effect of a tax rate change on deferred taxes is recognized in operations in the period that the change in the rate is enacted. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. Under the provisions of FASB ASC Topic

740,

the Company had

material unrecognized tax positions and

adjustments to liabilities or operations were required. The Company, when applicable, will recognize interest and penalties related to uncertain tax positions in income tax expense. There was

expense related to interest and penalties for the years ended

December 31, 2020

and

2019,

respectively.

Earnings Per Share.

Basic earnings per share (“EPS”) is computed by dividing earnings (losses) attributable to common shareholders by the weighted average number of common shares outstanding for the periods. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

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 and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reported periods. Actual results could differ from those estimates. These management estimates are primarily related to impairment of long-lived assets, allowance for bad debt, warrant valuations, and inventory valuation.

Subsequent Events.

The Company evaluated subsequent events through the filing of its Annual Report on Form

-K with the SEC.

Supplemental Cash Flow Information.

Cash payments for interest and income taxes were

for each of the years ended

December 31, 2020

and

2019,

respectively.

Recent Accounting Pronouncements.

Financial Instruments- Credit Losses

June 2016,

the FASB issued an accounting standards update that changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. This update replaces the existing incurred loss impairment model with an expected loss model (referred to as the Current Expected Credit Loss model, or "CECL"). The standard update, and its related amendments, will become effective for the fiscal year beginning on

January 1, 2023.

The Company is in the process of assessing the impact of this standard update, and its related amendments, on the Company's consolidated financial statements, but is

not

expecting it will have a material impact on the Company's consolidated financial statements.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the AICPA and the SEC did

not

or are

not

believed by management to have a material impact on the Company's present or future consolidated financial statements.

Note 3 - Significant Transactions	Dec. 31, 2020
Notes to Financial Statements
Significant Transactions [Text Block]	3 . Significant Transactions 2019 Restructuring Plan In July 2019, the Company adopted a restructuring plan pursuant to which the Company elected to wind down its prior manufacturing operations at the Company's Lake Forest, CA facility and proceeded to outsource the manufacture of parts utilizing the Company's technology through its domestic and international manufacturing partners (the “2019 Restructuring Plan”). In connection with the 2019 Restructuring Plan, the Company shifted its business strategy from internal manufacture of parts and products for customers toward the use and reliance of outsourced manufacturers, which will initially be Dongguan Yihao Metals Materials Technology Co., Ltd. (“Yihao”), a China-based company in which our largest beneficial stockholder, CEO and Chairman, Professor Lugee Li, has a material, indirect, equity interest. Manufacturing Facility Purchase On February 16, 2017, the Company purchased a 41,000 square foot manufacturing facility (the “Facility”) located in Lake Forest, CA, where operations commenced during July 2017. The purchase price for the Facility was $7,818. As a result of the 2019 Restructuring Plan, the Company has discontinued manufacturing operations in the Facility. Facility Lease On January 23, 2020, 20321 Valencia, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, entered into a lease agreement (the “Facility Lease”) pursuant to which the Company leased to MatterHackers, Inc., a Delaware corporation (“Tenant”), an approximately 32,534 square foot portion of the Facility. The lease term is for 5 years and 2 months and is scheduled to expire on April 30, 2025. The base rent payable under the Facility Lease is $33 per month initially and is subject to periodic increases up to a maximum of approximately $54 per month. Tenant will pay approximately 79% of common operating expresses. The Facility Lease has other customary provisions, including provisions relating to default and usage restrictions. The Facility Lease grants to Tenant a right to extend the lease for one additional 60 -month period at market rental value. 2016 Purchase Agreement On March 10, 2016, the Company entered into the 2016 Purchase Agreement with Liquidmetal Technology Limited, a Hong Kong company (the “Investor”), which is controlled by the Company's Chairman and CEO, Professor Li. The 2016 Purchase Agreement provided for the purchase by the Investor of a total of 405,000,000 shares of the Company's common stock for an aggregate purchase price of $63,400. The transaction occurred in multiple closings, with the Investor having purchased 105,000,000 shares at a purchase price of $8,400 (or $0.08 per share) at the initial closing on March 10, 2016 and the remaining 200,000,000 shares at $0.15 per share and 100,000,000 shares at $0.25 per share for an aggregate purchase price of $55,000 on October 26, 2016. In addition to the shares issuable under the 2016 Purchase Agreement, the Company issued to the Investor a warrant to acquire 10,066,809 shares of common stock (of which the right to exercise 2,609,913 of the warrant shares vested on March 10, 2016 and the right to exercise the remaining 7,456,896 warrant shares vested on October 26, 2016 at an exercise price of $0.07 per share). The warrant will expire on the tenth anniversary of its issuance date. The 2016 Purchase Agreement also provided that, with certain limited exceptions, if the Company issues any shares of common stock at any time through the fifth anniversary of the 2016 Purchase Agreement, the Investor will have a preemptive right to subscribe for and to purchase at the same price per share (or at market price, in the case of issuance of shares pursuant to stock options) the number of shares necessary to maintain its ownership percentage of Company-issued shares of common stock. Eontec License Agreement On March 10, 2016, in connection with the 2016 Purchase Agreement, the Company and Eontec, entered into the License Agreement pursuant to which the Company and Eontec agreed to cross-license their respective technologies. The Company's Chairman and CEO, Professor Li, is also a major shareholder and Chairman of Eontec. The License Agreement provides for the cross-license of certain patents, technical information, and trademarks between the Company and Eontec. In particular, the Company granted to Eontec a paid-up, royalty-free, perpetual license to the Company's patents and related technical information to make, have made, use, offer to sell, sell, export, and import products in certain geographic areas outside of North America and Europe. In turn, Eontec granted to the Company a paid-up, royalty-free, perpetual license to Eontec's patents and related technical information to make, have made, use, offer to sell, sell, export, and import products in certain geographic areas outside of specified countries in Asia. The license granted by the Company to Eontec is exclusive (including to the exclusion of the Company) in the countries of Brunei, Cambodia, China (P.R.C and R.O.C.), East Timor, Indonesia, Japan, Laos, Malaysia, Myanmar, Philippines, Singapore, South Korea, Thailand, and Vietnam. The license granted by Eontec to the Company is exclusive (including to the exclusion of Eontec) in North America and Europe. The cross-licenses are non-exclusive in geographic areas outside of the foregoing exclusive territories. Beyond the License Agreement, the Company collaborates with Eontec to accelerate the commercialization of amorphous alloy technology. This includes but is not limited to developing technologies to reduce the cost of amorphous alloys, working on die cast machine technology platforms to pursue broader markets, sharing knowledge to broaden our intellectual property portfolio, and utilizing Eontec's volume production capabilities as a third party contract manufacturer. Eutectix Business Development Agreement On January 31, 2020, the Company entered into a Business Development Agreement (the “Agreement”) with Eutectix, which provides for collaboration, joint development efforts, and the manufacturing of products based on the Company's proprietary amorphous metal alloys. Under the Agreement, the Company licensed to Eutectix specified equipment owned by the Company, including two injection molding machines, two diecasting machines, and other machines and equipment, all of which will be used to make product for Company customers and Eutectix customers. The licensed machines and equipment represented substantially all of the machinery and equipment then held by the Company. The Company has also licensed to Eutectix various patents and technical information related to the Company's proprietary technology. Under the Agreement, Eutectix agreed to pay the Company a royalty of six percent ( 6% ) of the net sales price of licensed products sold by Eutectix, and Eutectix will also manufacture for the Company product ordered by the Company. The Agreement has a term of five years, subject to renewal provisions and the ability of either party to terminate earlier upon specified circumstances. Apple License Transaction On August 5, 2010, the Company entered into a license transaction with Apple pursuant to which (i) the Company contributed substantially all of its intellectual property assets to a newly organized special-purpose, wholly-owned subsidiary, called CIP, (ii) CIP granted to Apple a perpetual, worldwide, fully-paid, exclusive license to commercialize such intellectual property in the field of consumer electronic products, as defined in the license agreement, in exchange for a license fee, and (iii) CIP granted back to the Company a perpetual, worldwide, fully-paid, exclusive license to commercialize such intellectual property in all other fields of use. Under the agreements relating to the license transaction with Apple, the Company was obligated to contribute, to CIP, all intellectual property developed through February 2016. The Company is also obligated to maintain certain limited liability company formalities with respect to CIP at all times after the closing of the license transaction. Other Material License Transactions The Company's majority-owned Liquidmetal Golf subsidiary has the exclusive right and license to utilize the Company's Liquidmetal alloy technology for purposes of golf equipment applications. This right and license is set forth in an intercompany license agreement between Liquidmetal Technologies and Liquidmetal Golf. This license agreement provides that Liquidmetal Golf has a perpetual and exclusive license to use Liquidmetal alloy technology for the purpose of manufacturing, marketing, and selling golf club parts and other products used in the sport of golf. The Company owns 79% of the outstanding common stock of Liquidmetal Golf. In March 2009, the Company entered into a license agreement with Swatch under which Swatch was granted a non-exclusive license to the Company's technology to produce and market watches and certain other luxury products. In March 2011, this license agreement was amended to grant Swatch exclusive rights as to watches as against all third parties (including the Company), but non-exclusive as to Apple. The Company will receive royalty payments over the life of the contract on all Liquidmetal products produced and sold by Swatch. The license agreement with Swatch will expire on the expiration date of the last licensed patent.

it determined that the losses were primarily the result of current economic factors, impacting all global debt and equity markets, that are the result of the global COVID-

pandemic. The impact to the Company's investment portfolio is considered to be temporary, rather than a deterioration of overall credit quality. The Company does

not

The valuation allowance increased

and

2020

and

2019,

respectively. Changes in the valuation allowance are impacted by the expiration of net operating loss (“NOL”) carryforwards, current year net operating losses, and changes to future tax deductions resulting from the terms of stock compensation plans and accrued liabilities.

The following table accounts for the differences between the expected federal tax benefit (based on the statutory

2020

As of

December 31, 2020,

the Company had approximately

$142.1

million of NOL carryforwards for U.S. federal income tax purposes expiring in

2021

through

2040.

As of

December 31, 2020,

the Company had approximately

$99.9

million of NOL carryforwards for California income tax purposes expiring in

2021

through

2040,

respectively. The Company and Liquidmetal Golf, Inc. file on a separate company basis for federal income tax purposes. Accordingly, the federal NOL carryforwards of

one

legal entity are

not

available to offset federal taxable income of the other. Liquidmetal Golf, Inc. had approximately

$23.7

million in federal NOL carryforwards, expiring in

2021

through

2040.

We recognize excess tax benefits associated with the exercise of stock options directly to shareholders' equity only when realized. Accordingly, deferred tax assets are

not

recognized for NOL carryforwards resulting from excess tax benefits. As of

December 31, 2020,

deferred tax assets do

not

include approximately

$437

of these tax effected excess tax benefits from employee stock option exercise that are a component of our NOL carryforwards. Accordingly, additional paid-in capital will increase up to an additional

$437

if and when such excess tax benefits are realized.

As of

December 31, 2020,

the Company had approximately

$87

of Research & Development (“R&D”) credit carryforwards for U.S. federal income tax purposes expiring in

2021

through

2030.

In addition, the Company has California R&D credit carryforwards of approximately

$243,

which do

not

expire under current California law.

Section

382

of the Internal Revenue Code (“IRC”) imposes limitations on the use of NOL's and credits following changes in ownership as defined in the IRC. The limitation could reduce the amount of benefits that would be available to offset future taxable income each year, starting with the year of an ownership change. As a result of the completion of the complex analysis required by the IRC to determine if an ownership change has occurred, the Company has determined that its annual NOL carryforward limitation under Section

382

of the IRC is

$764

per year.

The ability to realize the tax benefits associated with deferred tax assets, which includes benefits related to NOL's, is principally dependent upon the Company's ability to generate future taxable income from operations. The Company has provided a full valuation allowance for its net deferred tax assets due to the Company's net operating losses.

The Company adopted the provisions of FASB ASC Topic

470

– Income Taxes. At the adoption date and as of

December 31, 2020,

the Company had

material unrecognized tax benefits and

adjustments to liabilities or operations were required. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense which were
