Basis of Presentation and Significant Accounting Policies [Text Block] | Note 1 Business activities and summary of significant accounting policies Business activities RF Industries, Ltd., together with its five wholly owned subsidiaries (collectively, hereinafter the “Company”, ”we”, “us”, or “our”), primarily engages in the design, manufacture, and marketing of interconnect products and systems, including coaxial and specialty cables, fiber optic cables and connectors, and electrical and electronic specialty cables. For internal operating and reporting purposes, and for marketing purposes, as of the end of the fiscal year ended October 31, 2023, we classified our operations into the following five divisions/subsidiaries: (i) The RF Connector and Cable Assembly division designs, manufactures and distributes coaxial connectors and cable assemblies that are integrated with coaxial connectors; (ii) Cables Unlimited, Inc., the subsidiary that manufactures custom and standard cable assemblies, complex hybrid fiber optic power solution cables, adapters, and electromechanical wiring harnesses for communication, computer, LAN, automotive and medical equipment; (iii) Rel-Tech Electronics, Inc., the subsidiary that designs and manufacturers cable assemblies and wiring harnesses for blue chip industrial, oilfield, instrumentation and military customers; (iv) C Enterprises, Inc., the subsidiary that designs and manufactures quality connectivity solutions to telecommunications and data communications distributors; (v) Schroff Technologies International, Ltd., the subsidiary that manufactures and markets intelligent thermal control systems used by telecommunications companies across the U.S. and Canada, and shrouds for small cell integration and installation, and (vi) Microlab, the subsidiary that designs and manufactures high-performance RF and Microwave products enabling signal distribution and deployment of in-building DAS (distributed antenna systems), wireless base stations and small cell networks. The Cables Unlimited and C Enterprises divisions are Corning Cables Systems CAH Connections SM Use of estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Actual results may differ from those estimates. Principles of consolidation The accompanying consolidated financial statements include the accounts of RF Industries, Ltd., Cables Unlimited, Inc. (“Cables Unlimited”), Rel-Tech Electronics, Inc. (“Rel-Tech”), C Enterprises, Inc. (“C Enterprises”), Schroff Technologies International, Ltd. (“Schrofftech”), and Microlab/FXR LLC (“Microlab”), wholly owned subsidiaries of RF Industries, Ltd. All intercompany balances and transactions have been eliminated in consolidation. Liquidity As of October 31, 2023, the Company was in compliance with the covenants contained in the Loan Agreement. In January 2024, given the economic conditions and the associated impact on earnings, the Company amended the Loan Agreement to modify the financial covenants in order to avoid a potential covenant violation during the fiscal quarter ending January 31, 2024. The amendments effect changes to certain provisions and covenants as noted in Note 11. As of October 31, 2023, the Company was in compliance with all financial covenants contained in the Loan Agreement. The Company expects to maintain compliance with the financial covenants contained in the Loan Agreement, as amended in January 2024, for at least one year from the issuance of these financial statements based on its current expectations and forecasts. If economic conditions worsen and the Company’s earnings and operating cash flows do not start to recover as currently estimated by management, this could impact the Company’s ability to maintain compliance with the amended financial covenants and require the Company to seek additional amendments to the Loan Agreement. If the Company is not able to obtain such necessary additional amendments, this would lead to an event of default and, if not cured timely, the lender could require the Company to repay its outstanding debt. In that situation, the Company may not be able to raise sufficient debt or equity capital, or divest assets, to refinance or repay the lenders and may affect our ability to continue as a going concern. Cash equivalents The Company considers all highly-liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Revenue recognition On November 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) Inventories Inventories are stated at the lower of cost or net realizable value, with cost determined using the weighted average cost of accounting. Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. We regularly review inventory quantities on hand, future purchase commitments with our suppliers, and the estimated utility of our inventory. If our review indicates a reduction in utility below carrying value due to damage, physical deterioration, obsolescence, changes in price levels, or other causes, we reduce our inventory to a new cost basis through a charge to cost of sales in the period in which it occurs. The determination of market value and the estimated volume of demand used in the lower of cost or market analysis requires significant judgment. Property and equipment Equipment, tooling and furniture are recorded at cost and depreciated over their estimated useful lives (generally three five Goodwill Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Goodwill is not amortized, but is subject to impairment analysis at least once annually, which we perform in October, or more frequently upon the occurrence of an event or when circumstances indicate that a reporting unit’s carrying amount is greater than its fair value. We assess whether a goodwill impairment exists using both qualitative and quantitative assessments at the reporting level. Our qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we will not perform a quantitative assessment. Under the amendments of this update, the goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss should be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. We test our goodwill, trademarks and indefinite-lived assets for impairment at least annually or more frequently if events or changes in circumstances indicate these assets may be impaired. These events or circumstances require significant judgment and could include a significant change in the business climate, legal factors, operating performance indicators, competition and sale or disposition of all or a portion of a division. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. As of October 31, 2023, we performed an impairment test analysis for Microlab and as of July 31, 2023, we performed an impairment test analysis for Schrofftech. As noted, we test our goodwill, trademarks, and indefinite-lived intangible assets for impairment at least annually, which we have traditionally done in the fourth quarter, or on an interim basis when events or changes in circumstances suggest these assets may be impaired. Impairment is measured as the excess of the carrying value of the goodwill or indefinite-lived intangible asset over its fair value. No instances of goodwill impairment were identified as of October 31, 2023 and 2022. On June 15, 2011, we completed the acquisition of Cables Unlimited. Goodwill related to this acquisition is included within the Cables Unlimited reporting unit. As of May 19, 2015, we completed the acquisition of the CompPro product line. Goodwill related to this acquisition is included within the RF Connector and Cable Assembly Division. Effective June 1, 2015, we completed the acquisition of Rel-Tech. Goodwill related to this acquisition is included within the Rel-Tech reporting unit. On March 15, 2019, we completed the acquisition of C Enterprises; however, no goodwill resulted from this transaction. On November 4, 2019, we completed the acquisition of Schrofftech. Goodwill related to this acquisition is included within the Schrofftech reporting unit. On March 1, 2022, we completed the acquisition of Microlab. Goodwill related to this acquisition is included within the Microlab reporting unit. Long-lived assets We assess property, plant and equipment and intangible assets, which are considered definite-lived assets, for impairment. Definite-lived assets are reviewed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We measure recoverability of these assets by comparing the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If property and equipment and intangible assets are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair market value. We amortize our intangible assets with definite useful lives over their estimated useful lives and review these assets for impairment. We test our goodwill, trademarks and indefinite-lived assets for impairment at least annually or more frequently if events or changes in circumstances indicate these assets may be impaired. These events or circumstances require significant judgment and could include a significant change in the business climate, legal factors, operating performance indicators, competition and sale or disposition of all or a portion of a division. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. As of October 31, 2023, we performed an impairment test analysis for Microlab and as of July 31, 2023, we performed an impairment test analysis for Schrofftech. As noted above, we test our goodwill, trademarks, and indefinite-lived intangible assets for impairment at least annually, which we have traditionally done in the fourth quarter, or on an interim basis when events or changes in circumstances suggest these assets may be impaired. Impairment is measured as the excess of the carrying value of the goodwill or indefinite-lived intangible asset over its fair value. Impairment may result from a number of factors, including performance deterioration, negative cash flows from operations and/or changes in anticipated future cash flows, changes in business plans, adverse economic or market conditions, or other factors beyond our control. The amount of any impairment must be expensed as a charge to operations. Microlab’s results for the fiscal year ended October 31, 2023 triggered an impairment analysis. Schrofftech’s three and nine-months results ended July 31, 2023 triggered an impairment analysis. Microlab was acquired in March 1, 2022 for a total purchase price of $24.5 million. Schrofftech was acquired on November 4, 2019 for a total purchase price of $5.3 million, consisting of cash consideration of $4.0 million and $1.3 million in earn-out, of which none was earned. As of October 31, 2023, Microlab has a carrying value of $17.2 million, of which includes $5.6 million in goodwill, $11.6 million in net amortizable intangible assets. As of October 31, 2023, Schrofftech has a carrying value of $3.1 million, of which includes $1.1 million in goodwill, $0.5 million in non-amortizable intangible assets and $1.5 million in net amortizable intangible assets. The analyses performed included a blend of the income approach (discounted cash flow method) and market approach (guideline public company method) to reach a fair value of equity in excess of the fair value to the carrying amount. The analyses performed in blending the income approach and the market approach incorporates several significant judgments and assumptions about projected revenue growth, future operating margins and discount rates. There are inherent uncertainties related to these assumptions and our judgment in applying them to the impairment analysis. Changes in certain events or circumstances could result in changes to our estimated fair values, and may result in future write-downs to the carrying values of these assets. Impairment charges could adversely affect our financial results, financial ratios and could limit our ability to obtain financing in the future. No Fair value measurement We measure at fair value certain financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs have created the following fair-value hierarchy: Level 1— Quoted prices for identical instruments in active markets; Level 2— Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3— Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. As of October 31, 2023 and 2022, the carrying amounts reflected in the accompanying consolidated balance sheets for cash and cash equivalents, accounts receivable, and accounts payable approximated their carrying value due to their short-term nature. Intangible assets Intangible assets consist of the following as of October 31, 2023 and 2022 (in thousands): 2023 2022 Amortizable intangible assets: Non-compete agreement (estimated life 5 years) $ 423 $ 423 Accumulated amortization (378 ) (334 ) 45 89 Customer relationships (estimated lives 7 - 15 years) 6,058 6,058 Accumulated amortization (3,461 ) (3,074 ) 2,597 2,984 Backlog (estimated life 1 - 2 years) 327 327 Accumulated amortization (327 ) (313 ) - 14 Patents (estimated life 10 - 14 years) 368 368 Accumulated amortization (176 ) (143 ) 192 225 Tradename (estimated life 15 years) 1,700 1,700 Accumulated amortization (189 ) (76 ) 1,511 1,624 Proprietary technology (estimated life 10 years) 11,100 11,100 Accumulated amortization (1,850 ) (740 ) 9,250 10,360 Totals $ 13,595 $ 15,296 Non-amortizable intangible assets: Trademarks $ 1,174 $ 1,174 Amortization expense was $1,701,000 and $1,282,000 for the years ended October 31, 2023 and 2022, respectively. The weighted-average amortization period for the amortizable intangible assets is 8.55 years. There was no Estimated amortization expense related to finite-lived intangible assets is as follows (in thousands): Year ending October 31, Amount 2024 $ 1,688 2025 1,643 2026 1,643 2027 1,643 2028 1,643 Thereafter 5,335 Total $ 13,595 Advertising We expense the cost of advertising and promotions as incurred. Advertising costs charged to operations were approximately $76,000 and $333,000 in 2023 and 2022, respectively. Research and development Research and development costs are expensed as incurred. Our research and development expenses relate to its engineering activities, which consist of the design and development of new products for specific customers, as well as the design and engineering of new or redesigned products for the industry in general. During the years ended October 31, 2023 and 2022, we recognized $3,151,000 and $2,913,000 in engineering expenses, respectively. Income taxes We account for income taxes under the asset and liability method, based on the income tax laws and rates in the jurisdictions in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Developing the provision (benefit) for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Management’s judgments and tax strategies are subject to audit by various taxing authorities. We had adopted the provisions of ASC 740-10, which clarifies the accounting for uncertain tax positions. ASC 740-10 requires that we recognize the impact of a tax position in the financial statements if the position is not more likely than not to be sustained upon examination based on the technical merits of the position. We recognize interest and penalties related to certain uncertain tax positions as a component of income tax expense and the accrued interest and penalties are included in deferred and income taxes payable in our consolidated balance sheets. See Note 8 to the Consolidated Financial Statements included in this Report for more information on the Company’s accounting for uncertain tax positions. Stock options For stock option grants to employees, we recognize compensation expense based on the estimated fair value of the options at the date of grant. Stock-based employee compensation expense is recognized on a straight-line basis over the requisite service period. We issue previously unissued common shares upon the exercise of stock options. For the fiscal years ended October 31, 2023 and 2022, charges related to stock-based compensation amounted to approximately $898,000 and $689,000, respectively. For the fiscal years ended October 31, 2023 and 2022, all stock-based compensation is classified in selling and general and engineering expense. Earnings per share Basic earnings per share is calculated by dividing net (loss) income applicable to common stockholders by the weighted average number of common shares outstanding during the period. The calculation of diluted earnings per share is similar to that of basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares, principally those issuable upon the exercise of stock options, were issued and the treasury stock method had been applied during the period. The greatest number of shares potentially issuable upon the exercise of stock options in any period for the years ended October 31, 2023 and 2022, that were not included in the computation because they were anti-dilutive, totaled 811,135 and 508,889, respectively. The following table summarizes the computation of basic and diluted earnings per share: 2023 2022 Numerators: Consolidated net (loss) income (A) $ (3,078,000 ) $ 1,448,000 Denominators: Weighted average shares outstanding for basic earnings per share (B) 10,283,449 10,120,254 Add effects of potentially dilutive securities - assumed exercise of stock options - 122,163 Weighted average shares outstanding for diluted earnings per share (C) 10,283,449 10,242,417 Basic (loss) earnings per share (A)/(B) $ (0.30 ) $ 0.14 Diluted (loss) earnings per share (A)/(C) $ (0.30 ) $ 0.14 Recent accounting standards Recently issued accounting pronouncements not yet adopted: In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, Financial Instruments Credit Losses Financial Instruments Credit Losses (Topic 326), Recently issued accounting pronouncements adopted: In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes |
