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, 2020

and

March 31, 2019

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, 2020

are

not

necessarily indicative of the results that

may

be expected for any future periods or the year ending

December 31, 2020.

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

2019

Annual Report on Form

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

March 10, 2020.

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, 2020

and

2019.

air 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, 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)	$	4,970	$	1,013	$	3,957	$	-
Investments in debt securities (long-term)		5,533		720		4,813		-

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		-

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 offset 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.
