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.

Basis of Presentation and Significant Accounting Policies [Text Block]

Basis of Presentation and Recent Accounting Pronouncements

The accompanying unaudited interim consolidated financial statements as of and for the

three

months ended

March 31, 2021

and

March 31, 2020

have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and in accordance with the instructions to Form

-Q. Accordingly, they do

not

include all of the information and notes required by US GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. All intercompany balances and transactions have been eliminated in consolidation. Operating results for the

three

months ended

March 31, 2021

are

not

necessarily indicative of the results that

may

be expected for any future periods or the year ending

December 31, 2021.

The accompanying unaudited consolidated financial statements should be read in conjunction with the Company's

2020

Annual Report on Form

-K filed with the Securities and Exchange Commission (“SEC”) on

March 9, 2021.

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

three

months ended

March 31, 2021

and

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

March 31, 2021,

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)	$	17,213		12,837		4,376		-
Investments in debt securities (long-term)		10,057		-		10,057		-

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		-

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 a prepaid expense in 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.

Other recent pronouncements

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants 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.

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 ("Professor 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 expenses. 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 a Securities Purchase Agreement (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 DongGuan Eontec Hong Kong corporation ("Eontec"), entered into a Parallel License Agreement (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.
