Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These <em style="font: inherit;">two</em> types of inputs have created the following fair-value hierarchy:</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Level&#xa0;<em style="font: inherit;">1</em> &#x2013; Quoted prices for identical instruments in active markets;</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Level&#xa0;<em style="font: inherit;">2</em> &#x2013; Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are <em style="font: inherit;">not</em> active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets;&#xa0;and</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;">Level&#xa0;<em style="font: inherit;">3</em> &#x2013; Valuations derived from valuation techniques in which <em style="font: inherit;">one</em> or more significant inputs or significant value drivers are unobservable.</p> <p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin: 0pt; text-align: left">&#xa0;</p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As of <em style="font: inherit;"> January 31, 2022 </em>and <em style="font: inherit;"> October 31, 2021, </em>the carrying amounts reflected in the accompanying condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, and accounts payable approximated their carrying value due to their short-term nature.

The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset.

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. The guidance also still gives entities the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.

The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures.

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Expected volatilities are based on historical volatility of our stock price and other factors. We used the historical method to calculate the expected life of the <em style="font: inherit;">2022</em> and <em style="font: inherit;">2021</em> option grants. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options&#x2019; expected life. The dividend yield is based upon the historical dividend yield.</p>

Based upon this evaluation, as of <em style="font: inherit;"> January 31, 2022, </em>we had <em style="font: inherit;">two</em> segments &#x2013; RF Connector and Cable Assembly (&#x201c;RF Connector segment&#x201d;) and Custom Cabling Manufacturing and Assembly (&#x201c;Custom Cabling segment&#x201d;).</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">The RF Connector segment consisted of <em style="font: inherit;">one</em> division and the Custom Cabling segment was composed of <em style="font: inherit;">four</em> divisions.&#xa0;The <em style="font: inherit;">five</em> divisions that met the quantitative thresholds for segment reporting are the RF Connector and Cable Assembly division (&#x201c;RF Connector division&#x201d;), Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech. While each segment has similar products and services, there was little overlapping of these services to their customer base. The biggest difference in segments is in the channels of sales: sales or product and services for the RF Connector&#xa0;segment were primarily through the distribution channel, while the Custom Cabling segment sales were through a combination of distribution and direct to the end customer.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Management identifies segments based on strategic business units that are, in turn, based along market lines. These strategic business units offer products and services to different markets in accordance with their customer base and product usage. For segment reporting purposes, the RF Connector division constitutes the RF Connector segment, and the Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech divisions constitute the Custom Cabling segment.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As reviewed by our chief operating decision maker, we evaluate the performance of each segment based on income or loss before income taxes. We charge depreciation and amortization directly to each division within the segment. Accounts receivable, inventory, property and equipment, right of use assets, goodwill and intangible assets are the only assets identified by segment. Except as discussed above, the accounting policies for segment reporting are the same for the Company as a whole.</p>

  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (&#x201c;GAAP&#x201d;). The preparation of these consolidated financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to bad debts, inventory reserves, earn-out liabilities, and contingencies on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be appropriate under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><i>Inventories</i></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Inventories are stated at the lower of cost or net realizable value, with cost determined using the weighted average cost method of accounting. Certain items in inventory may be considered obsolete or excess and, as such, we periodically review our inventories for excess and slow moving items and make provisions as necessary to properly reflect inventory value. Because inventories have, during the past few years, represented up to one-fourth of our total assets, any reduction in the value of our inventories would require us to take write-offs that would affect our net worth and future earnings.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We record an allowance for doubtful accounts based upon our assessment of various factors. We consider historical experience, the age of the accounts receivable balance, credit quality of our customers, current economic conditions and other factors that may affect a customer&#x2019;s ability to pay.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">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.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We amortize our intangible assets with definite useful lives over their estimated useful lives and review these assets for impairment.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We test our goodwill and 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.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The purchase agreement for the acquisition of Schrofftech provided for an earn-out payment of up to $2.4 million, which amount was earned through October 31, 2021. Since the earn-out period has expired, no earn-out liability was required to be recorded for the fiscal quarter ended January 31, 2022. The initial earn-out liability was valued at its fair value using an option pricing based approach with a risk-neutral framework using Black Scholes due to the option-like nature of the earn-out payout structure. The earn-out was revalued quarterly using a present value approach, and any resulting increase or decrease were recorded into selling and general expenses. Changes in the amount of the actual results and forecasted scenarios resulted in an adjustment to the fair value. Significant judgment was employed in determining the appropriateness of the assumptions used in calculating the fair value of the earn-out as of the acquisition date.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We record a tax provision for the anticipated tax consequences of the reported results of operations. Income taxes are accounted for under the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates as of the date of the financial statements that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The calculation of the tax provision involves significant judgment in estimating the impact of uncertainties in the application of GAAP and complex tax laws. Resolution of these uncertainties in a manner inconsistent with management&#x2019;s expectations could have a material impact on our financial condition and operating results.&#xa0;</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We use the Black-Scholes model to value the stock option grants. This valuation is affected by our stock price as well as assumptions regarding a number of inputs which involve significant judgments and estimates. These inputs include the expected term of employee stock options, the expected volatility of the stock price, the risk-free interest rate and expected dividends.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We operate through two reporting segments: (i) the RF Connector and Cable Assembly (&#x201c;RF Connector&#x201d;) segment, and (ii) the Custom Cabling Manufacturing and Assembly (&#x201c;Custom Cabling&#x201d;) segment. The RF Connector segment primarily designs, manufactures, markets and distributes a broad range of connector and cable products, including coaxial connectors and cable assemblies that are integrated with coaxial connectors, used in telecommunications and information technology OEM markets and other end markets. The Custom Cabling segment designs, manufactures, markets and distributes custom copper and fiber cable assemblies, complex hybrid fiber optic and power solution cables, electromechanical wiring harnesses, wiring harnesses for a broad range of applications in a diverse set of end markets, energy-efficient cooling systems for wireless base stations and remote equipment shelters and custom designed, pole-ready 5G small cell integrated enclosures.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">For the three months ended January 31, 2022, most of our revenues were generated from the Custom Cabling segment from the sale of fiber optics cable, copper cabling, custom patch cord assemblies, and wiring harnesses, which collectively accounted for 77% of the Company&#x2019;s total sales. Revenues from the RF Connector segment were generated from the sales of RF connector products and cable assemblies and accounted for 23% of total sales for the three months ended January 31, 2022. The RF Connector segment mostly sells standardized products regularly used by customers and, therefore, has a more stable revenue stream. On the other hand, the Custom Cabling segment mostly designs, manufactures, and sells customized cabling and wireless-related equipment under larger purchase orders. Accordingly, the Custom Cabling segment is more dependent upon larger orders, and its revenues are therefore, more volatile than the revenues of the RF Connector segment.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">On March 1, 2022, the Company purchased&#xa0;Microlab/FXR LLC, a New Jersey limited liability company (&#x201c;Microlab&#x201d;), from Wireless Telecom Group, Inc. for $24,250,000, subject to certain post-closing adjustments. The purchase price was paid in cash at the closing. The Company funded $17 million of the cash purchase price from the funds obtained under the term loan it obtained from Bank of America, N.A. (the &#x201c;Credit Facility Lender&#x201d;) and paid the remaining amount of the cash purchase price with cash on hand. The purpose of the acquisition is to acquire a synergistic business that is expected to both (i) be accretive to the financial performance of the Company and (ii) enhance our market position by providing a broader and deeper product portfolio, accelerating our product and innovation roadmap, expanding our production capabilities, and enhancing our customer relationships.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In order to fund the purchase of Microlab, on February 25, 2022, the Company entered into a Loan Agreement with the Credit Facility Lender, which facility provides the Company with a $3 million revolving credit facility (the &#x201c;Revolving Credit Facility&#x201d;) and a $17 million term loan (the &#x201c;Term Loan&#x201d;, collectively with the &#x201c;Revolving Credit Facility&#x201d;, the &#x201c;Credit Facility&#x201d;). The primary interest rate for Term Loan is 3.76% per annum. The maturity date of the Term Loan is March 1, 2027. Borrowings under the Credit Facility are guaranteed by the Company and certain of its subsidiaries and secured by all personal property of the Company and certain of its subsidiaries. The Credit Facility requires the maintenance of certain financial covenants, including: (i) consolidated debt to EBITDA ratio not to exceed 3.00 to 1.00; (ii) consolidated fixed charge coverage ratio of at least 1.25 to 1.00; and (iii) consolidated minimum EBITDA of at least $600,000 for the discrete quarter ending January 31, 2022. In addition, the Credit Facility contains customary affirmative and negative covenants.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The COVID-19 coronavirus pandemic, in its various strains, negatively affected both our operations and those of our customers. The extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on future developments, including the duration and spread of the pandemic and related actions taken by domestic and international jurisdictions to prevent disease spread, all of which are uncertain and cannot be predicted. The outbreak impacted our performance in fiscal year 2021 and for the three months ended January 31, 2022. During the periods covered by this report, the operations at all locations were affected intermittently as some of our employee schedules were impacted, and as certain customers scaled back operations or otherwise delayed or deferred orders for our products. Because of the impact that COVID-19 had on our operations, in May 2020 we applied for and received loans under the Paycheck Protection Program (&#x201c;PPP&#x201d;) of the Coronavirus Aid, Relief, and Economic Security Act, H.R. 748 (&#x201c;CARES Act&#x201d;)&#xa0;&#xa0;totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;). In February 2021, all of the $2.8 million of PPP Loans were forgiven and considered paid in full (including applicable interest) by the Small Business Administration (&#x201c;SBA&#x201d;).</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In March 2021, the Internal Revenue Service (&#x201c;IRS&#x201d;) released Notice 2021-20, which retroactively eliminated the restriction that prevented employers who received a PPP loan from qualifying for the Employee Retention Credit (&#x201c;ERC&#x201d;), which is a refundable tax credit against certain employment taxes. Upon determination that the employer has complied with all of the conditions required to receive the credit, a receivable is recognized and the credit reduces salaries and wages. For the fiscal year ended October 31, 2021, we qualified and filed to claim the ERC and have recorded the credit as a receivable in Other Current Assets. As of January 31, 2022, we carried a $1.8 million the ERC receivable in Other Current Assets.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><b>Liquidity and Capital Resources</b></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Historically, we have been able to fund our liquidity and other capital requirements from funds we generated from operations. On March 1, 2022, we acquired Microlab. In connection with the purchase of Microlab, we entered into the Credit Facility and borrowed the full $17 million amount available under the Term Loan. As of the date of this report, we have not borrowed any amounts under the Revolving Credit Facility. We believe that our existing assets and the cash we expect to generate from operations (including those of Microlab) and from our current backlog of unfulfilled orders, will be sufficient to fund our liquidity needs during the next twelve months from the date of this filing based on the following:</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As of January 31, 2022, we had a total of $13.5 million of cash and cash equivalents compared to a total of $13.1 million of cash and cash equivalents as of October 31, 2021. As of January 31, 2022, we had working capital of $31.3 million and a current ratio of approximately 4.2:1 with current assets of $41 million and current liabilities of $9.7 million. On March 1, 2022 we used $7.3 million of our cash to fund a portion of the purchase price paid to acquire Microlab. Nevertheless, we believe that the amount of cash remaining, plus the amount available to us under the Revolving Credit Facility, will be sufficient to fund our anticipated liquidity needs.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As of January 31, 2022, we had $27.9 million of backlog, compared to $33.3 million as of October 31, 2021. Since purchase orders are submitted from customers based on the timing of their requirements, our ability to predict orders in future periods or trends in future periods is limited. Furthermore, purchase orders may be subject to cancellation from customers, although we have not historically experienced material cancellations of purchase orders.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In the three months ended January 31, 2022, we generated $0.6 million of cash in our operating activities. This net inflow of cash is primarily related to the collections of accounts receivable of $3.0 million, $0.2 million from depreciation and amortization and $0.1 million from stock-based compensation expense. The cash usage was primarily due to an increase to our inventory purchases ($2.3 million) and our net loss ($0.3&#xa0;million). The cash used for other current assets represents of ($0.7&#xa0;million) which consists of ($0.2 million) in application of prepaid taxes, ($0.3&#xa0;million, of which $0.2 million related to Microlab) in prepaid expenses and ($0.2&#xa0;million) in deposits for inventory purchases.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The acquisition of Microlab&#xa0;will affect both our liquidity and our capital resources in the near future. In order to acquire Microlab, we used $7.3 million of our cash on hand to pay a portion of the purchase price, thereby reducing the amount available for future acquisitions, for investments in the expansion of our existing businesses and assets, or as a reserve for unanticipated financial requirements. For example, during the three months ended January 31, 2022, we spent $103,000 on capital expenditures, of which $13,000 related to purchases in preparation of the Microlab. We may be required to make additional future capital expenditures to integrate Microlab&#xa0;with our other operations or to relocate or consolidate the facilities of Microlab&#xa0;and one or more of other subsidiaries. Also, in order to purchase Microlab, we borrowed $17 million under the Term Loan. The future monthly payments of principal and interest will negatively impact our future cash available from operations and our liquidity. Although the acquisition of Microlab&#xa0;is anticipated to be accretive and to generate positive cash flow, the actual impact of the acquisition of Microlab&#xa0;on our consolidated financial results, and the operating synergies that will actually be generated from the integration of Microlab&#xa0;with our other operations, are currently unknown. In the event that the future operating and financial results of Microlab&#xa0;are less than anticipated, or if some of the anticipated synergies are not realized, our liquidity and capital resources may be further negatively impacted by the acquisition of that company.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Our goal to expand and grow our business both organically and through acquisitions&#xa0;may require material additional capital equipment. In the past, we have purchased all additional equipment, or financed some of our equipment and furnishings requirements through capital leases. Currently, no additional capital equipment purchases have been identified that would require significant additional leasing or capital expenditures during the next twelve months. We also believe that based on our current financial condition, our current backlog of unfulfilled orders and our anticipated future operations, we would be able to finance our expansion, if necessary.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">From time to time, we may undertake acquisitions of other companies or product lines in order to diversify our product and solutions offerings and customer base. Conversely, we may undertake the disposition of a division or product line due to changes in our business strategy or market conditions.&#xa0;Acquisitions may require the outlay of cash, which may reduce our liquidity and capital resources while dispositions may increase our cash position, liquidity and capital resources. Since our goal is to continue to expand our operations and accelerate our growth through future acquisitions, we may use some of our current capital resources to fund any acquisitions we may undertake in the future.</p>

Net sales for the fiscal 2022 quarter at the Custom Cabling segment increased by $6.6 million, or 102%, to $13.0 million, compared to $6.4 million in the fiscal 2021 quarter. The increase was primarily the result of project-based wireless carrier macro and tower site business related to the sale of fiber optic cables used in the build out of 4G and 5G networks.&#xa0; Net sales for the fiscal 2022 quarter at the RF Connector segment increased by $0.3 million, or 10%, to $3.9 million as compared to $3.6 million in the fiscal 2021 quarter.</p>

The decrease in the pretax net income at the RF Connector segment was primarily due to decline in gross margin as well as an increase in selling and administrative expenses to support a higher sales number. The increase in pretax income at the Custom Cabling segment was due primarily to the increase in sales of hybrid fiber to a tier-1 wireless customer.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The discussion of our business and operations should be read together with the risk factors contained in Item&#xa0;1A of our Annual Report on Form 10-K for the fiscal year ended October&#xa0;31, 2021 filed with the SEC, which describe various risks and uncertainties to which we are or may become subject. Further, the current coronavirus (&#x201c;COVID-19&#x201d;) pandemic and actions taken to address the pandemic may exacerbate the risks described in our reports filed with the Securities and Exchange Commission (the &#x201c;SEC&#x201d;). These risks and uncertainties have the potential to affect our business, financial condition, results of operations, cash flows, strategies or prospects in a material and adverse manner.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As of January 31, 2022, we had a total of $13.5 million of cash and cash equivalents. On March 1, 2022, we purchased Microlab from Wireless Telecom Group, Inc. for $24,250,000, subject to certain post-closing adjustments. The Company funded $17 million of the cash purchase price from the funds obtained under the term loan it obtained from Bank of America, N.A. (the &#x201c;Credit Facility Lender&#x201d;) and paid the remaining amount of the cash purchase price with cash on hand. In order to acquire Microlab, we used $7.3 million of our cash on hand to pay a portion of the purchase price, thereby reducing the amount of cash available for future acquisitions, for investments in the expansion of our existing businesses and assets, or as a reserve for unanticipated financial requirements.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"><b><i>The Company entered into a Loan Agreement to fund its acquisition of Microlab, which may expose the Company and its subsidiaries to additional risks, including risks associated with the inability to repay the loan on a timely basis.</i></b></p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">On February 25, 2022, the Company entered into a Loan Agreement with the Credit Facility Lender, which facility provides the Company with a $3 million revolving credit facility (the &#x201c;Revolving Credit Facility&#x201d;) and a $17 million term loan (the &#x201c;Term Loan&#x201d;, collectively with the &#x201c;Revolving Credit Facility&#x201d;, the &#x201c;Credit Facility&#x201d;). The Company borrowed the full $17 million amount available under the Term Loan in order to fund the purchase of Microlab. The maturity date of the Term Loan is March 1, 2027. Borrowings under the Credit Facility are guaranteed by the Company and certain of its subsidiaries and secured by all personal property of the Company and certain of its subsidiaries. The Credit Facility requires the maintenance of certain financial covenants, including: (i) consolidated debt to EBITDA ratio not to exceed 3.00 to 1.00; (ii) consolidated fixed charge coverage ratio of at least 1.25 to 1.00; and (iii) consolidated minimum EBITDA of at least $600,000 for the discrete quarter ending January 31, 2022. In addition, the Credit Facility contains customary affirmative and negative covenants. In the event that the Company is unable to pay its obligations on the Credit Facility on a timely basis, maintain the financial covenants under the Loan Agreement or otherwise defaults on its obligations under the Loan Agreement, the Credit Facility Lender will have a right to foreclose on personal property of the Company and certain of its subsidiaries.</p>

  <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">The uncertain state of the global economy (including the current conflict between Russia and Ukraine and related economic and other retaliatory measures taken by the United States, European Union and others) continues to impact businesses around the world. Deteriorating economic conditions or financial uncertainty in any of the markets in which we sell our products could reduce business confidence and adversely impact spending patterns, and thereby could adversely affect our sales and results of operations. In challenging and uncertain economic environments such as the current one, we cannot predict whether or when such circumstances may improve or worsen, or what impact, if any, such circumstances could have on our business, financial condition and results of operations, or on the price of our common stock.</p>

  <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">Recent inflationary pressures have increased the cost of energy and raw materials and may adversely affect our results of operations. If inflation continues to rise and further impact the cost of energy and raw materials, we may not be able to offset cost increases to our products through price adjustments without negatively impacting consumer demand, which could adversely affect our sales and results of operations.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">1. I have reviewed this report on Form 10-Q for the quarter ended January 31, 2022 of RF Industries, Ltd.;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">3. Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">4. I am responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(a) Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period for which this report is being prepared;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(b) Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(d) Disclosed in this report any change in the registrant&#8217;s internal control over financial reporting that occurred during the registrant&#8217;s most recent fiscal quarter (the registrant&#8217;s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrant&#8217;s internal control over financial reporting; and</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">5. I have disclosed, based on my most recent evaluation of internal control over financial reporting, to the registrant&#8217;s auditors and to the audit committee of the registrant&#8217;s board of directors (or persons performing the equivalent functions):</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant&#8217;s ability to record, process, summarize and report information; and</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">1. I have reviewed this report on Form 10-Q for the quarter ended January 31, 2022 of RF Industries, Ltd.;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">3. Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">4. I am responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(a) Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period for which this report is being prepared;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(b) Designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(c) Evaluated the effectiveness of the registrant&#8217;s disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(d) Disclosed in this report any change in the registrant&#8217;s internal control over financial reporting that occurred during the registrant&#8217;s most recent fiscal quarter (the registrant&#8217;s fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrant&#8217;s internal control over financial reporting; and</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">5. I have disclosed, based on my most recent evaluation of internal control over financial reporting, to the registrant&#8217;s auditors and to the audit committee of the registrant&#8217;s board of directors (or persons performing the equivalent functions):</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant&#8217;s ability to record, process, summarize and report information; and</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant&#8217;s internal control over financial reporting.</p>

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.

The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures.

If the employer&#8217;s employment tax deposits are <em style="font: inherit;">not</em> sufficient to cover the credit, the employer <em style="font: inherit;"> may </em>get an advance payment from the IRS. The period assessed for eligibility of the ERC is on a calendar year basis.&#160;As of <em style="font: inherit;"> January 31, 2022, </em>the remaining portion of the ERC that we have <em style="font: inherit;">not</em> yet received is included as other receivables in other current assets.</p>

The earn-out was revalued quarterly using a present value approach and any resulting increase or decrease was recorded into selling and general expenses. Significant variances between actual and forecasted results or changes in the assumptions affected the amount of contingent consideration expense that we recorded from time to time.

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding increased by the effects of assuming that other potentially dilutive securities (such as stock options) outstanding during the period had been exercised and the treasury stock method had been applied. During the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> January 31, 2022 </em>and <em style="font: inherit;">2021,</em> we reported a net loss and diluted loss per share is computed the same as basic loss per share as the effect of utilizing the fully diluted share count would have reduced the net loss per share which has an anti-dilutive effect. Therefore, all outstanding stock options are excluded from the computation of diluted loss per share. Potentially issuable securities that are out-of-the-money totaled 459,889 and 331,338 shares for the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> January 31, 2022 </em>and <em style="font: inherit;">2021,</em> respectively, and were excluded from the calculation of diluted per share amounts because of their anti-dilutive effect.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Expected volatilities are based on historical volatility of our stock price and other factors. We used the historical method to calculate the expected life of the <em style="font: inherit;">2022</em> and <em style="font: inherit;">2021</em> option grants. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options&#8217; expected life. The dividend yield is based upon the historical dividend yield.</p>

In addition, the Chairman of the Board of Directors and the Chair of each committee of the Board of Directors received an annual retainer of $15,000, also payable in restricted shares, that vests in <em style="font: inherit;">four</em> equal quarterly installments commencing on <em style="font: inherit;"> September 15, 2020 </em>and ending on the earlier of <em style="font: inherit;"> September 15, 2021 </em>or the next annual meeting of stockholders.

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We aggregate operating divisions into two reporting segments that have similar economic characteristics primarily in the following areas: (<em style="font: inherit;">1</em>) the nature of the product and services; (<em style="font: inherit;">2</em>) the nature of the production process; (<em style="font: inherit;">3</em>) the type or class of customer for their products and services; (<em style="font: inherit;">4</em>) the methods used to distribute their products or services; and (<em style="font: inherit;">5</em>) if applicable, the nature of the regulatory environment. Based upon this evaluation, as of <em style="font: inherit;"> January 31, 2022, </em>we had <em style="font: inherit;">two</em> segments &#8211; RF Connector and Cable Assembly (&#8220;RF Connector segment&#8221;) and Custom Cabling Manufacturing and Assembly (&#8220;Custom Cabling segment&#8221;).</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">The RF Connector segment consisted of <em style="font: inherit;">one</em> division and the Custom Cabling segment was composed of <em style="font: inherit;">four</em> divisions.&#160;The <em style="font: inherit;">five</em> divisions that met the quantitative thresholds for segment reporting are the RF Connector and Cable Assembly division (&#8220;RF Connector division&#8221;), Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech. While each segment has similar products and services, there was little overlapping of these services to their customer base. The biggest difference in segments is in the channels of sales: sales or product and services for the RF Connector&#160;segment were primarily through the distribution channel, while the Custom Cabling segment sales were through a combination of distribution and direct to the end customer.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Management identifies segments based on strategic business units that are, in turn, based along market lines. These strategic business units offer products and services to different markets in accordance with their customer base and product usage. For segment reporting purposes, the RF Connector division constitutes the RF Connector segment, and the Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech divisions constitute the Custom Cabling segment.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">As reviewed by our chief operating decision maker, we evaluate the performance of each segment based on income or loss before income taxes. We charge depreciation and amortization directly to each division within the segment. Accounts receivable, inventory, property and equipment, right of use assets, goodwill and intangible assets are the only assets identified by segment. Except as discussed above, the accounting policies for segment reporting are the same for the Company as a whole.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">All of our operations are conducted in the United States; however, we derive a portion of our revenue from export sales. We attribute sales to geographic areas based on the location of the customers. The following table presents the sales by geographic area for the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> January 31, 2022 </em>and <em style="font: inherit;">2021</em> (in thousands):</p>

The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The guidance is effective for fiscal years beginning after <em style="font: inherit;"> December 15, 2019. </em>In <em style="font: inherit;"> November 2019, </em>the FASB issued ASU <em style="font: inherit;">2019</em>-<em style="font: inherit;">10,</em> Financial Instruments&#8212;Credit Losses (Topic <em style="font: inherit;">326</em>), which pushes back the effective date for public business entities that are smaller reporting companies, as defined by the SEC, to fiscal years beginning after <em style="font: inherit;"> December 15, 2022. </em>Early adoption is permitted.

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. The guidance also still gives entities the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. We adopted the standard as of <em style="font: inherit;"> November 1, 2020, </em>the beginning of our fiscal <em style="font: inherit;">2021,</em> applying this prospectively.

The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance was effective for the Company beginning on <em style="font: inherit;"> November 1, 2021 </em>and prescribes different transition methods for the various provisions.

The COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; pandemic has negatively impacted regional and global economies, disrupted global supply chains, and created significant volatility and disruption of financial markets. The extent of the impact of the COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; pandemic on our operational and financial performance will depend on future developments, including the duration and spread of the pandemic and related actions taken by domestic and international jurisdictions to prevent disease spread, all of which are uncertain and cannot be predicted.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;The outbreak impacted our performance for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022. &lt;/em&gt;During the periods covered by this report, the operations at all locations were affected intermittently as some of our employee schedules were impacted, and as certain customers scaled back operations or otherwise delayed or deferred orders for our products. Because of the impact that COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; had on our operations, in &lt;em style="font: inherit;"&gt; May 2020 &lt;/em&gt;we applied for and received loans under the Paycheck Protection Program (&#x201c;PPP&#x201d;) of the Coronavirus Aid, Relief, and Economic Security Act, H.R. &lt;em style="font: inherit;"&gt;748&lt;/em&gt; ("CARES Act") totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;). See Note &lt;em style="font: inherit;"&gt;12&lt;/em&gt; on discussions of the PPP Loans.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;In &lt;em style="font: inherit;"&gt; March 2021, &lt;/em&gt;the Internal Revenue Service (&#x201c;IRS&#x201d;) released Notice &lt;em style="font: inherit;"&gt;2021&lt;/em&gt;-&lt;em style="font: inherit;"&gt;20,&lt;/em&gt; which retroactively eliminated the restriction that prevented employers who received a PPP loan from qualifying for the Employee Retention Credit (&#x201c;ERC&#x201d;), which is a refundable tax credit against certain employment taxes.

The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The guidance is effective for fiscal years beginning after &lt;em style="font: inherit;"&gt; December 15, 2019. &lt;/em&gt;In &lt;em style="font: inherit;"&gt; November 2019, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;2019&lt;/em&gt;-&lt;em style="font: inherit;"&gt;10,&lt;/em&gt; Financial Instruments&#x2014;Credit Losses (Topic &lt;em style="font: inherit;"&gt;326&lt;/em&gt;), which pushes back the effective date for public business entities that are smaller reporting companies, as defined by the SEC, to fiscal years beginning after &lt;em style="font: inherit;"&gt; December 15, 2022. &lt;/em&gt;Early adoption is permitted. We are currently evaluating the impact the adoption of this new standard will have on our consolidated financial statements.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;&lt;b&gt;&lt;i&gt;Recently issued accounting pronouncements adopted:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;In &lt;em style="font: inherit;"&gt; January 2017, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;No.&lt;/em&gt; &lt;em style="font: inherit;"&gt;2017&lt;/em&gt;-&lt;em style="font: inherit;"&gt;04,&lt;/em&gt; Intangibles&#x2014;Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step &lt;em style="font: inherit;"&gt;2&lt;/em&gt; from the goodwill impairment test. 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. The guidance also still gives entities the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. We adopted the standard as of &lt;em style="font: inherit;"&gt; November 1, 2020, &lt;/em&gt;the beginning of our fiscal &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; applying this prospectively. The adoption of the standard did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; result in an impairment charge as of &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;or &lt;em style="font: inherit;"&gt; October 31, 2021.&lt;/em&gt;&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;In &lt;em style="font: inherit;"&gt; December 2019, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;2019&lt;/em&gt;-&lt;em style="font: inherit;"&gt;12,&lt;/em&gt;&#160;Income Taxes (Topic &lt;em style="font: inherit;"&gt;740&lt;/em&gt;): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance was effective for the Company beginning on &lt;em style="font: inherit;"&gt; November 1, 2021 &lt;/em&gt;and prescribes different transition methods for the various provisions. The adoption of this standard had &lt;em style="font: inherit;"&gt;no&lt;/em&gt; material impact on the Company&#x2019;s financial statements or related disclosures.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;

The COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; pandemic has negatively impacted regional and global economies, disrupted global supply chains, and created significant volatility and disruption of financial markets. The extent of the impact of the COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; pandemic on our operational and financial performance will depend on future developments, including the duration and spread of the pandemic and related actions taken by domestic and international jurisdictions to prevent disease spread, all of which are uncertain and cannot be predicted.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;The outbreak impacted our performance for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022. &lt;/em&gt;During the periods covered by this report, the operations at all locations were affected intermittently as some of our employee schedules were impacted, and as certain customers scaled back operations or otherwise delayed or deferred orders for our products. Because of the impact that COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; had on our operations, in &lt;em style="font: inherit;"&gt; May 2020 &lt;/em&gt;we applied for and received loans under the Paycheck Protection Program (&#x201c;PPP&#x201d;) of the Coronavirus Aid, Relief, and Economic Security Act, H.R. &lt;em style="font: inherit;"&gt;748&lt;/em&gt; ("CARES Act") totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;).

We are currently evaluating the impact the adoption of this new standard will have on our consolidated financial statements.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;&lt;b&gt;&lt;i&gt;Recently issued accounting pronouncements adopted:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;In &lt;em style="font: inherit;"&gt; January 2017, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;No.&lt;/em&gt; &lt;em style="font: inherit;"&gt;2017&lt;/em&gt;-&lt;em style="font: inherit;"&gt;04,&lt;/em&gt; Intangibles&#x2014;Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step &lt;em style="font: inherit;"&gt;2&lt;/em&gt; from the goodwill impairment test. 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. The guidance also still gives entities the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. We adopted the standard as of &lt;em style="font: inherit;"&gt; November 1, 2020, &lt;/em&gt;the beginning of our fiscal &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; applying this prospectively. The adoption of the standard did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; result in an impairment charge as of &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;or &lt;em style="font: inherit;"&gt; October 31, 2021.&lt;/em&gt;&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt; &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;In &lt;em style="font: inherit;"&gt; December 2019, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;2019&lt;/em&gt;-&lt;em style="font: inherit;"&gt;12,&lt;/em&gt;&#160;Income Taxes (Topic &lt;em style="font: inherit;"&gt;740&lt;/em&gt;): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance was effective for the Company beginning on &lt;em style="font: inherit;"&gt; November 1, 2021 &lt;/em&gt;and prescribes different transition methods for the various provisions. The adoption of this standard had &lt;em style="font: inherit;"&gt;no&lt;/em&gt; material impact on the Company&#x2019;s financial statements or related disclosures.&lt;/p&gt; &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Pursuant to the CARES Act, eligible employers are able to claim an ERC, which is a refundable tax credit against certain employment taxes. If the employer&#x2019;s employment tax deposits are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; sufficient to cover the credit, the employer &lt;em style="font: inherit;"&gt; may &lt;/em&gt;get an advance payment from the IRS. The period assessed for eligibility of the ERC is on a calendar year basis.&#160;As of &lt;em style="font: inherit;"&gt; January 31, 2022, &lt;/em&gt;the remaining portion of the ERC that we have &lt;em style="font: inherit;"&gt;not&lt;/em&gt; yet received is included as other receivables in other current assets.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Accrued receipts represent purchased inventory for which invoices have &lt;em style="font: inherit;"&gt;not&lt;/em&gt; been received.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;The purchase agreement for the Schrofftech acquisition provided for earn-out payments of up to $2,400,000, which were to be earned through &lt;em style="font: inherit;"&gt; October 31, 2021. &lt;/em&gt;The initial earn-out liability was valued at its fair value using an option pricing based approach with a risk-neutral framework using Black Scholes due to the option-like nature of the earn-out payout structure. The earn-out was revalued quarterly using a present value approach and any resulting increase or decrease was recorded into selling and general expenses. Significant variances between actual and forecasted results or changes in the assumptions affected the amount of contingent consideration expense that we recorded from time to time. In determining the fair value of the earn-out liability as of &lt;em style="font: inherit;"&gt; October 31, 2021, &lt;/em&gt;we used results through &lt;em style="font: inherit;"&gt; October 31, 2021.&lt;/em&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;We estimated the fair value of the earn-out liability using an option pricing based approach with a risk-neutral framework using Black Scholes related to Schrofftech calculated at net present value (Level &lt;em style="font: inherit;"&gt;3&lt;/em&gt; of the fair value hierarchy). At &lt;em style="font: inherit;"&gt; October 31, 2021, &lt;/em&gt;the fair value of the Schrofftech earn-out liability was zero, and since the earn-out obligation expired on &lt;em style="font: inherit;"&gt; October 31, 2021, &lt;/em&gt;&lt;em style="font: inherit;"&gt;no&lt;/em&gt; earn-out liability was recorded for the period ended &lt;em style="font: inherit;"&gt; January 31, 2022.&lt;/em&gt;&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding increased by the effects of assuming that other potentially dilutive securities (such as stock options) outstanding during the period had been exercised and the treasury stock method had been applied. During the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; we reported a net loss and diluted loss per share is computed the same as basic loss per share as the effect of utilizing the fully diluted share count would have reduced the net loss per share which has an anti-dilutive effect. Therefore, all outstanding stock options are excluded from the computation of diluted loss per share. Potentially issuable securities that are out-of-the-money totaled 459,889 and 331,338 shares for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; respectively, and were excluded from the calculation of diluted per share amounts because of their anti-dilutive effect.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Expected volatilities are based on historical volatility of our stock price and other factors. We used the historical method to calculate the expected life of the &lt;em style="font: inherit;"&gt;2022&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; option grants. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options&#x2019; expected life. The dividend yield is based upon the historical dividend yield.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Under the compensation policies adopted by the Compensation Committee, directors who also are officers and/or employees of the Company do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; receive any compensation for serving on the Board. For their service as directors beginning in &lt;em style="font: inherit;"&gt;2020&lt;/em&gt; until the annual meeting of stockholders held in &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; non-employee directors (i.e., directors who are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; employed by the Company as officers or employees) were awarded $50,000 as Board fees, which amount was payable (a) &lt;em style="font: inherit;"&gt;one&lt;/em&gt;-half in cash (&lt;em style="font: inherit;"&gt;$25,000&lt;/em&gt;), with payments made on a quarterly basis, and (b) &lt;em style="font: inherit;"&gt;one&lt;/em&gt;-half through the grant of restricted shares that vest on a quarterly basis. In addition, the Chairman of the Board of Directors and the Chair of each committee of the Board of Directors received an annual retainer of $15,000, also payable in restricted shares, that vests in &lt;em style="font: inherit;"&gt;four&lt;/em&gt; equal quarterly installments commencing on &lt;em style="font: inherit;"&gt; September 15, 2020 &lt;/em&gt;and ending on the earlier of &lt;em style="font: inherit;"&gt; September 15, 2021 &lt;/em&gt;or the next annual meeting of stockholders. In each case, the equity portion of the award was calculated based on the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average trailing closing price of the Company's common stock from the date of grant ($4.34); and cash and stock payments were pro-rated for board members who served less than the entire service period during fiscal &lt;em style="font: inherit;"&gt;2021.&lt;/em&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;On &lt;em style="font: inherit;"&gt; September 8, 2021, &lt;/em&gt;the Board of Directors determined that the compensation payable to directors as Board fees for the next year ending with the &lt;em style="font: inherit;"&gt;2022&lt;/em&gt; annual meeting of stockholders was the same as they received in &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; (i.e., $50,000). In addition, effective &lt;em style="font: inherit;"&gt; September 8, 2021, &lt;/em&gt;the Board determined that both Board fees and additional chair fees would be paid half in cash and half in restricted stock, and, in light of the additional work required by the chairs, revised the chair fees as follows, $25,000 for the Chairman of the Board, $25,000 for the Audit Committee Chair, $20,000 for the Compensation Committee Chair, $20,000 for the Strategic Planning and Capital Allocation Chair, and $10,000 for the Nominating &amp;amp; Governance Chair. The cash and restricted stock fees vest in &lt;em style="font: inherit;"&gt;four&lt;/em&gt; equal quarterly installments commencing on &lt;em style="font: inherit;"&gt; December 8, 2021, &lt;/em&gt;with the restricted stock portion determined by dividing the amount of the fee by the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average trailing closing price of the Company&#x2019;s common stock from the date of grant ($8.21). Accordingly, on &lt;em style="font: inherit;"&gt; September 8, 2021, &lt;/em&gt;Mr. Holdsworth was granted 5,785 shares of restricted stock; Ms. Cefali, 4,871 shares; Mr. Garland, 4,567 shares; and Mr. Fink, 3,044 shares.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"&gt;&lt;b&gt;&lt;i&gt;Stock option expense&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;During the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; stock-based compensation expense totaled $139,000 and $123,000, respectively, and was classified in selling and general expense.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;We aggregate operating divisions into two reporting segments that have similar economic characteristics primarily in the following areas: (&lt;em style="font: inherit;"&gt;1&lt;/em&gt;) the nature of the product and services; (&lt;em style="font: inherit;"&gt;2&lt;/em&gt;) the nature of the production process; (&lt;em style="font: inherit;"&gt;3&lt;/em&gt;) the type or class of customer for their products and services; (&lt;em style="font: inherit;"&gt;4&lt;/em&gt;) the methods used to distribute their products or services; and (&lt;em style="font: inherit;"&gt;5&lt;/em&gt;) if applicable, the nature of the regulatory environment. Based upon this evaluation, as of &lt;em style="font: inherit;"&gt; January 31, 2022, &lt;/em&gt;we had &lt;em style="font: inherit;"&gt;two&lt;/em&gt; segments &#x2013; RF Connector and Cable Assembly (&#x201c;RF Connector segment&#x201d;) and Custom Cabling Manufacturing and Assembly (&#x201c;Custom Cabling segment&#x201d;).&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;The RF Connector segment consisted of &lt;em style="font: inherit;"&gt;one&lt;/em&gt; division and the Custom Cabling segment was composed of &lt;em style="font: inherit;"&gt;four&lt;/em&gt; divisions.&#160;The &lt;em style="font: inherit;"&gt;five&lt;/em&gt; divisions that met the quantitative thresholds for segment reporting are the RF Connector and Cable Assembly division (&#x201c;RF Connector division&#x201d;), Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech. While each segment has similar products and services, there was little overlapping of these services to their customer base. The biggest difference in segments is in the channels of sales: sales or product and services for the RF Connector&#160;segment were primarily through the distribution channel, while the Custom Cabling segment sales were through a combination of distribution and direct to the end customer.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Management identifies segments based on strategic business units that are, in turn, based along market lines. These strategic business units offer products and services to different markets in accordance with their customer base and product usage. For segment reporting purposes, the RF Connector division constitutes the RF Connector segment, and the Cables Unlimited, Rel-Tech, C Enterprises, and Schrofftech divisions constitute the Custom Cabling segment.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;As reviewed by our chief operating decision maker, we evaluate the performance of each segment based on income or loss before income taxes. We charge depreciation and amortization directly to each division within the segment. Accounts receivable, inventory, property and equipment, right of use assets, goodwill and intangible assets are the only assets identified by segment. Except as discussed above, the accounting policies for segment reporting are the same for the Company as a whole.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;All of our operations are conducted in the United States; however, we derive a portion of our revenue from export sales. We attribute sales to geographic areas based on the location of the customers. The following table presents the sales by geographic area for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; (in thousands):&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;We use an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate, to determine its quarterly benefit&#160;for income taxes. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;We recorded income tax benefits&#160;of $80,000 and $194,000&#160;for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; respectively. The effective tax rate was 22.3% for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022, &lt;/em&gt;compared to 32.4% for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2021. &lt;/em&gt;The change in effective tax rate for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;compared to the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; January 31, 2021 &lt;/em&gt;was primarily driven by stock compensation windfall benefits. &#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;text-indent:36pt;"&gt;We had $174,000 and $141,000 of unrecognized tax benefits, inclusive of interest and penalties, as of &lt;em style="font: inherit;"&gt; January 31, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt; October 31, 2021, &lt;/em&gt;respectively.

The funds from the PPP Loans were used to retain employees, maintain payroll and benefits, and make lease and utility payments.
