2.     Summary of Significant Accounting Policies

 

During the three months ended March 31, 2024, there were no material changes to our significant accounting policies included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report") filed with the Securities and Exchange Commission (the "SEC") on March 25, 2024. For additional information, refer to Note B to the audited Consolidated and Combined Financial Statements in the 2023 Annual Report.

 

Basis of Presentation

 

These unaudited Condensed Consolidated Financial Statements do not include all disclosures that are normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and should be read in conjunction with the audited Consolidated and Combined Financial Statements and the related notes included in the "2023 Annual Report. The consolidated financial information as of  December 31, 2023 included herein has been derived from the audited Consolidated and Combined Financial Statements in the 2023 Annual Report.

 

In the opinion of management, these Condensed Consolidated Financial Statements contain all adjustments (consisting of normal recurring adjustments, including eliminations of material intercompany accounts and transactions) considered necessary for a fair statement of the results presented herein. Operating results for the three months ended  March 31, 2024 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2024.

 

Use of Estimates

 

The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

 

Research and Development Costs

 

Research and development costs are charged to operations as incurred. For the three months ended  March 31, 2024 and 2023, such costs were approximately $633 and $529, respectively, and are included within Engineering, selling and administrative expenses on the Condensed Consolidated Statements of Operations.

Concentration Risks

 

For the three months ended  March 31, 2024, the Company's largest and second largest customers accounted for $4,875, or 43.6%, and $2,203, or 19.7%, of the Company's Revenues, respectively. For the three months ended March 31, 2023, the Company's largest and second largest customers accounted for $2,334, or 24.9%, and $1,009, or 10.8%, of the Company’s Revenues, respectively. 

 

A significant portion of the Company's accounts receivable is concentrated with a relatively small number of customers. As of March 31, 2024, the Company's four largest customers accounted for approximately $4,227, or 73.6%, of gross accounts receivable. As of December 31, 2023, four of the Company's largest customers accounted for approximately $3,774, or 76.4%, of gross accounts receivable. The Company carefully evaluates the creditworthiness of its customers in deciding to extend credit. As a result, the Company has experienced very low historical bad debt expense and believes the related risk to be minimal.

 

Impairments of Long-Lived Assets

 

Long-lived assets, including intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Long-lived assets are grouped with other assets to the lowest level to which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Management assesses the recoverability of the carrying cost of the assets based on a review of projected undiscounted cash flows. If an asset is held for sale, management reviews its estimated fair value less cost to sell. Fair value is determined using pertinent market information, including appraisals or broker's estimates, and/or projected discounted cash flows. In the event an impairment loss is identified, it is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset.

 

We performed an assessment to determine if there were any indicators of impairment as of  March 31, 2024 and December 31, 2023.We concluded that, while there were events and circumstances in the macro-environment that did impact us, we did not experience any entity-specific indicators of asset impairment and no triggering events occurred.

 

Future Application of Accounting Standards

 

Segment Reporting

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODM with an explanation of how the CODM uses the report measure(s) of segment profits or losses in assessing segment performance. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is applied retrospectively to all prior periods presented. We are assessing the impact of this standard.

 

Income Taxes

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures" ("ASU 2023-09"). The standard requires disaggregated information about a company's effective tax rate reconciliation as well as information on income taxes paid. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2024, with early adoption permitted. This standard applies prospectively; however, retrospective application is permitted. We are assessing the impact of this standard.

Investment Activity with GAMCO Investors, Inc.

 

Certain balances are held and invested in U.S. Treasury funds managed or advised by GAMCO Investors, Inc. or one of its subsidiaries (collectively, "GAMCO" or the "Fund Manager"), which is related to the Company through certain of our shareholders. For the three months ended  March 31, 2024 and March 31, 2023, the Company paid the Fund Manager a fund management fee of approximately 8 basis points annually of the asset balances under management, which are not paid directly by the Company and are deducted prior to the fund striking its net asset value ("NAV").

Transactions with The LGL Group, Inc.

 

Transitional Administrative and Management Services Agreement

On October 7, 2022, the separation of the MtronPTI business from The LGL Group, Inc. ("LGL Group") was completed (the "Separation") and the Company became an independent, publicly traded company trading on the NYSE American under the stock symbol "MPTI." The Separation was completed through LGL Group's distribution (the "Distribution") of 100% of the shares of the Company's common stock to holders of LGL Group's common stock as of the close of business on September 30, 2022, the record date for the Distribution. 

 

MtronPTI and The LGL Group, Inc. ("LGL Group") entered into an Amended and Restated Transitional Administrative and Management Services Agreement ("MtronPTI TSA"), which sets out the terms for services to be provided between the two companies post Separation. The current terms result in a net monthly payment of $4 per month from LGL Group to MtronPTI.

 

For the three months ended  March 31, 2024 and 2023, LGL Group paid the Company $12 under the terms of the MtronPTI TSA, which were recorded in Other income (expense), net on the Condensed Consolidated Statements of Operations.

 

Tax Indemnity and Sharing Agreement

MtronPTI and LGL Group entered into a Tax Indemnity and Sharing Agreement ("MtronPTI Tax Agreement"), which sets out the terms for which party would be responsible for taxes imposed on LGL Group if the Distribution, together with certain related transactions, were to fail to qualify as a tax-free transaction under Internal Revenue Code ("IRC") Sections 355 and 368(a)(1)(D) if such failure were the result of actions taken after the Distribution by MtronPTI or LGL Group.

 

For the three months ended  March 31, 2024 and 2023, no taxes related to the Distribution have been recorded in the Condensed Consolidated Financial Statements.

 

Other Transactions

MtronPTI and LGL Group agreed to share the salaries and benefits related to certain employees incurred by LGL Group. For the three months ended  March 31, 2024, the Company reimbursed LGL Group $26 of the salaries and benefits of certain employees, which represents 50% of those costs and were recorded in Engineering, selling and administrative on the Condensed Consolidated Statements of Operations.

 

MtronPTI and LGL Group agreed to share any excess Separation costs. For the three months ended  March 31, 2023, costs directly related to the Separation were $56, which were incurred by LGL Group. Included in Other income (expense), net on the Condensed Consolidated Statements of Operations is $28, which represents 50% of the excess Separation costs incurred for the three months ended  March 31, 2023.

4.     Income Taxes

 

The Company’s quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items within the period presented. To determine the annual effective tax rate, the Company estimates both the total income (loss) before income taxes for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective tax rate for the full year may differ from these estimates if income (loss) before income taxes is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations.

 

The effective tax rate for the three months ended  March 31, 2024 and 2023 was 20.2% and 23.1%, respectively. Differences between the Company’s effective income tax rate and the U.S. federal statutory rate are primarily the impact of research and development credits, permanent differences, and state taxes.

 

5.     Revolving Credit Agreement

 

On June 15, 2022, MtronPTI entered into a loan agreement (the “Loan Agreement”) for a revolving line of credit with Fifth Third Bank, National Association (“Fifth Third Bank”), for up to $5,000 bearing interest at the Secured Overnight Financing Rate (“SOFR”) plus a margin of 2.25%, with a SOFR floor of 0.00%. The Loan Agreement has a maturity date of June 15, 2025 and contains various affirmative and negative covenants that are customary for lines of credit and transactions of this type, including limitations on the incurrence of debt and liabilities, as well as financial reporting requirements. The Loan Agreement also imposes certain financial covenants based on Debt Service Coverage Ratio, Current Ratio, and the Ratio of Total Liabilities to Total Net Worth (as such terms are defined in the Loan Agreement). All loans pursuant to the Loan Agreement will be secured by a continuing and unconditional first priority security interest in and to any and all property of the Company.

 

As of  March 31, 2024 and December 31, 2023, there were no outstanding borrowings under the revolving line of credit with Fifth Third Bank.

Item 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

 

The following discussion and analysis of the Company's financial condition and results of operations should be read in conjunction with the accompanying unaudited Condensed Consolidated Financial Statements, the notes thereto and the other unaudited financial data included in this Quarterly Report on Form 10-Q. The following discussion should also be read in conjunction with the audited Consolidated and Combined Financial Statements and the notes thereto, and "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2024. The terms the “Company”, “MtronPTI”, “MPTI”, “we”, “our” or “us” refer to M-tron Industries, Inc. and unless otherwise defined herein, capitalized terms used herein shall have the same meanings as set forth in our Condensed Consolidated Financial Statements and the notes thereto.

 

Unless otherwise stated, all dollar amounts are in thousands.

 

In addition to historical data, this discussion contains forward-looking statements about our business, operations and financial performance based on current expectations that involve risks, uncertainties and assumptions. Actual results may differ materially from those discussed in the forward-looking statements as a result of various factors. See the Cautionary Note Concerning Forward-Looking Statements included in this Quarterly Report on Form 10-Q.

 

Overview

 

MtronPTI is engaged in the designing, manufacturing and marketing of highly-engineered, high reliability frequency and spectrum control products used to control the frequency or timing of signals in electronic circuits in various applications. MtronPTI’s primary markets are defense, aerospace, space, and avionics.

 

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of the Company and all of its majority-owned subsidiaries.

 

Trends and Uncertainties

 

We are not aware of any material trends or uncertainties, other than national economic conditions affecting our industry generally, that may reasonably be expected to have a material impact, favorable or unfavorable, on our revenues or income other than the one listed below and the risk factors disclosed in our Annual Report on Form 10-K, as filed with the SEC on March 25, 2024.

 

Inflation and Changing Interest Rates

 

Inflation in the United States decreased from 6.5% as of December 31, 2022 to 3.4% as of December 31, 2023, which is still above the U.S. Federal Reserve's long-term target of 2.0%. Although inflation is expected to continue to decrease in 2024, the continued higher inflationary conditions may have an adverse impact on our Manufacturing cost of sales along with Engineering, selling and administrative expenses, as these costs could increase at a rate higher than our revenue. The U.S. Federal Reserve raised the federal funds rate a total of four times throughout 2023, resulting in a range from 5.25% to 5.50% as of December 31, 2023. Through the date of this Quarterly Report on Form 10-Q, the Federal Reserve has maintained the federal funds rate in the same range as of December 31, 2023. It is expected that the U.S. Federal Reserve will continue to hold the federal funds rate steady or start to decrease it during 2024 to, among other things, control inflation; however, the timing of any such decrease remains unclear. As a result, we have increased the prices we charge our customers.

Three months ended March 31, 2024 compared to three months ended March 31, 2023

 

Total Revenues

Total revenues increased $1,818, or 19.4%, from $9,367 for the three months ended March 31, 2023 to $11,185 for the three months ended March 31, 2024 primarily due to strong defense product shipments.

 

Total Costs and Expenses

Total expenses increased $790, or 9.2%, from $8,606 for the three months ended March 31, 2023 to $9,396 for the three months ended March 31, 2024. The increase is primarily due to a $555, or 22.8%, increase in Engineering, selling and administrative from $2,435 for the three months ended March 31, 2023 to $2,990 for the three months ended March 31, 2024 from higher research and development costs, higher sales commissions related to an increase in revenues, and an increase in corporate expenses consistent with the overall growth in the business.

 

Gross Margin

Gross margin (Revenues less Manufacturing cost of sales as a percentage of Revenues), increased 861 basis points from 34.1% for the three months ended March 31, 2023 to 42.7% for the three months ended March 31, 2024 reflecting higher revenues and change in product mix to higher margin products.

 

Total Other Income (Expense), Net

Total Other income (expense), net increased $116, or 276.2%, from ($42) for the three months ended March 31, 2023 to $74 for the three months ended March 31, 2024.  The following items contributed to the overall increase:

•

a $34, or 1700.0%, increase in Interest income (expense), net from ($2) for the three months ended March 31, 2023 to $32 for the three months ended March 31, 2024 primarily due to interest income earned on investments in money market mutual funds.

•

a $82, or 205.0%, increase in Other income (expense), net from ($40) for the three months ended March 31, 2023 to $42 for the three months ended March 31, 2024 primarily due to favorable currency movements.

 

Income Tax Expense

Income tax expense increased $211, or 127.1%, from $166 for the three months ended March 31, 2023 to $377 for the three months ended March 31, 2024 primarily due to the increase in Income before income taxes driven by the increase in revenues discussed above.

 

Backlog

 

As of March 31, 2024, our order backlog was $46,130, a decrease of $1,701, or 3.6%, from $47,831 as of December 31, 2023 and an increase of $592, or 1.3%, from $45,538 as of March 31, 2023. The decrease in backlog from December 31, 2023 reflects an increase in revenue and timing of certain orders.

 

 

Liquidity and Capital Resources

 

Overview

Liquidity refers to our ability to access sufficient sources of cash to meet the requirements of our operating, investing and financing activities.

 

Capital refers to our long-term financial resources available to support business operations and future growth.

 

Our ability to generate and maintain sufficient liquidity and capital depends on the profitability of the business, timing of cash flows, general economic conditions and access to the capital markets and the other sources of liquidity and capital described herein.

Operating Activities

Cash provided by operating activities was $1,496 for the three months ended March 31, 2024 compared to cash provided by operating activities of $279 for the three months ended March 31, 2023, an increase of $1,217, primarily due to the following:

•

Net income increased $933 from $553 for the three months ended March 31, 2023 to $1,486 for the three months ended March 31, 2024.

•

Stock-based compensation increased $136 from $71 for the three months ended March 31, 2023 to $207 for the three months ended March 31, 2024.

 

The increase was partially offset by:

•

Net change in operating assets and liabilities increased $174 from ($534) for the three months ended March 31, 2023 to ($360) for the three months ended March 31, 2024.

 

Our working capital metrics and ratios were as follows:

(in thousands)		March 31, 2024				December 31, 2023
Current assets		$	20,723			$	18,187
Less: Current liabilities			5,057				4,384
Working capital		$	15,666			$	13,803
Current ratio			4.1				4.1

 

Management continues to focus on efficiently managing working capital requirements to match operating activity levels and will seek to deploy the Company’s working capital where it will generate the greatest returns.

 

Investing Activities

Cash used in investing activities was $122 for the three months ended March 31, 2024 compared to cash used in investing activities of $78 for the three months ended March 31, 2023, an increase of $44, primarily due to the purchase of equipment during the three months ended March 31, 2024.

 

Financing Activities

Cash provided by financing activities was $127 for the three months ended March 31, 2024 compared to cash provided by financing activities of $0 for the three months ended March 31, 2023, an increase of $127, primarily due to the exercise of stock options by an executive officer.

 

 

 

Capital Resources

 

We believe that existing cash and cash equivalents, marketable securities and cash generated from operations will provide sufficient liquidity to meet our ongoing working capital and capital expenditure requirements for the next 12 months from the date of this filing. At various times throughout the year and as of March 31, 2024 and December 31, 2023, some deposits held at financial institutions were in excess of federally insured limits. The Company has not experienced any losses related to these balances.

 

Our Board of Directors has adhered to a practice of not paying cash dividends. This policy takes into account our long-term growth objectives, including our anticipated investments for organic growth, potential acquisitions and stockholders' desire for capital appreciation of their holdings.

 

Revolving Line of Credit

 

On June 15, 2022, the Company entered into a loan agreement (the “Loan Agreement”) for a revolving line of credit with Fifth Third Bank, National Association ("Fifth Third Bank"), for up to $5,000 bearing interest at the Secured Overnight Financing Rate ("SOFR") plus a margin of 2.25%, with a SOFR floor of 0.00%. The Loan Agreement has a maturity date of June 15, 2025 and contains various affirmative and negative covenants that are customary for lines of credit and transactions of this type, including limitations on the incurrence of debt and liabilities, as well as financial reporting requirements. The Loan Agreement also imposes certain financial covenants based on Debt Service Coverage Ratio, Current Ratio, and the Ratio of Total Liabilities to Total Net Worth (as such terms are defined in the Loan Agreement). All loans pursuant to the Loan Agreement are secured by a continuing and unconditional first priority security interest in and to any and all property of the Company.

 

As of March 31, 2024 and December 31, 2023, there were no outstanding borrowings under the revolving line of credit with Fifth Third Bank.

 

Critical Accounting Estimates

 

The preparation of financial statements in conformity with U.S. GAAP requires management to adopt accounting policies related to estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period, as well as the related disclosure of contingent assets and liabilities at the date of the financial statements. On an ongoing basis, management evaluates its accounting policies, estimates and judgments, including those related to income taxes and inventories. Management bases its estimates and judgments on historical experience and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.

 

There have been no material changes to the critical accounting estimates disclosed in our Annual Report on Form 10-K, as filed with the SEC on March 25, 2024.

Item 4.

Controls and Procedures

 

Evaluation of Disclosure Controls and Procedures 

 

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the rules and forms, and that such information is accumulated and communicated to us, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, an evaluation as of March 31, 2024 was conducted under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures, as of March 31, 2024, were effective.

 

Changes in Internal Control Over Financial Reporting

 

There were no changes in the Company’s internal control over financial reporting during the quarter ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	2.     Summary of Significant Accounting Policies   During the three months ended March 31, 2024, there were no material changes to our significant accounting policies included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report") filed with the Securities and Exchange Commission (the "SEC") on March 25, 2024. For additional information, refer to Note B to the audited Consolidated and Combined Financial Statements in the 2023 Annual Report.   Basis of Presentation   These unaudited Condensed Consolidated Financial Statements do not include all disclosures that are normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and should be read in conjunction with the audited Consolidated and Combined Financial Statements and the related notes included in the "2023 Annual Report. The consolidated financial information as of  December 31, 2023 included herein has been derived from the audited Consolidated and Combined Financial Statements in the 2023 Annual Report.   In the opinion of management, these Condensed Consolidated Financial Statements contain all adjustments (consisting of normal recurring adjustments, including eliminations of material intercompany accounts and transactions) considered necessary for a fair statement of the results presented herein. Operating results for the three months ended  March 31, 2024 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2024.   Use of Estimates   The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.   Research and Development Costs   Research and development costs are charged to operations as incurred. For the three months ended  March 31, 2024 and 2023, such costs were approximately $633 and $529, respectively, and are included within Engineering, selling and administrative expenses on the Condensed Consolidated Statements of Operations.   Concentration Risks   For the three months ended  March 31, 2024, the Company's largest and second largest customers accounted for $4,875, or 43.6%, and $2,203, or 19.7%, of the Company's Revenues, respectively. For the three months ended March 31, 2023, the Company's largest and second largest customers accounted for $2,334, or 24.9%, and $1,009, or 10.8%, of the Company’s Revenues, respectively.    A significant portion of the Company's accounts receivable is concentrated with a relatively small number of customers. As of March 31, 2024, the Company's four largest customers accounted for approximately $4,227, or 73.6%, of gross accounts receivable. As of December 31, 2023, four of the Company's largest customers accounted for approximately $3,774, or 76.4%, of gross accounts receivable. The Company carefully evaluates the creditworthiness of its customers in deciding to extend credit. As a result, the Company has experienced very low historical bad debt expense and believes the related risk to be minimal.   Impairments of Long-Lived Assets   Long-lived assets, including intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Long-lived assets are grouped with other assets to the lowest level to which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Management assesses the recoverability of the carrying cost of the assets based on a review of projected undiscounted cash flows. If an asset is held for sale, management reviews its estimated fair value less cost to sell. Fair value is determined using pertinent market information, including appraisals or broker's estimates, and/or projected discounted cash flows. In the event an impairment loss is identified, it is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset.   We performed an assessment to determine if there were any indicators of impairment as of  March 31, 2024 and December 31, 2023.We concluded that, while there were events and circumstances in the macro-environment that did impact us, we did not experience any entity-specific indicators of asset impairment and no triggering events occurred.   Future Application of Accounting Standards   Segment Reporting In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODM with an explanation of how the CODM uses the report measure(s) of segment profits or losses in assessing segment performance. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is applied retrospectively to all prior periods presented. We are assessing the impact of this standard.   Income Taxes In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures" ("ASU 2023-09"). The standard requires disaggregated information about a company's effective tax rate reconciliation as well as information on income taxes paid. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2024, with early adoption permitted. This standard applies prospectively; however, retrospective application is permitted. We are assessing the impact of this standard.

Note 4 - Income Taxes	3 Months Ended
	Mar. 31, 2024
Notes to Financial Statements
Income Tax Disclosure [Text Block]	4.     Income Taxes   The Company’s quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items within the period presented. To determine the annual effective tax rate, the Company estimates both the total income (loss) before income taxes for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective tax rate for the full year may differ from these estimates if income (loss) before income taxes is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations.   The effective tax rate for the three months ended  March 31, 2024 and 2023 was 20.2% and 23.1%, respectively. Differences between the Company’s effective income tax rate and the U.S. federal statutory rate are primarily the impact of research and development credits, permanent differences, and state taxes.
