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.

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">In <em style="font: inherit;"> February 2016, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> Leases. This ASU requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the current GAAP. Under ASU <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients. We adopted the standard as of <em style="font: inherit;"> November 1, 2019, </em>the beginning of our fiscal <em style="font: inherit;">2020,</em> applying the modified retrospective method.&#xa0; We elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, allows us to carryforward the historical lease classification.&#xa0; We elected the policy which allows us to combine the nonlease components with their related lease components rather than separating, and the policy election to keep leases with an initial term of <em style="font: inherit;">12</em> months or less off of the balance sheet.&#xa0; Operating leases are included in our consolidated balance sheet as operating lease right of use (&#x201c;ROU&#x201d;) assets, other current liabilities, and operating lease liabilities. Finance leases are included in finance ROU assets, other current liabilities, and finance lease liabilities on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the duration of the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do <em style="font: inherit;">not</em> provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms <em style="font: inherit;"> may </em>include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is recognized on the consolidated statements of operations. The adoption of the standard resulted in a material recognition of additional ROU assets and lease liabilities of approximately $<ix:nonFraction id="c74202688" contextRef="i_2019-11-01_AdjustmentsForNewAccountingPronouncementsAxis-AccountingStandardsUpdate201602Member" unitRef="USD" name="us-gaap:OperatingLeaseRightOfUseAsset" scale="6" format="ixt:numdotdecimal" decimals="-5">2.3</ix:nonFraction> million and $<ix:nonFraction id="c74202689" contextRef="i_2019-11-01_AdjustmentsForNewAccountingPronouncementsAxis-AccountingStandardsUpdate201602Member" unitRef="USD" name="us-gaap:OperatingLeaseLiability" scale="6" format="ixt:numdotdecimal" decimals="-5">2.4</ix:nonFraction> million, respectively, as of <em style="font: inherit;"> November 1, 2019, </em>but did <em style="font: inherit;">not</em> materially affect our consolidated net loss.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In <em style="font: inherit;"> January 2017, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2017</em>-<em style="font: inherit;">04,</em> Intangibles&#x2014;Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step <em style="font: inherit;">2</em> 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 <em style="font: inherit;"> November 1, 2020, </em>the beginning of our fiscal <em style="font: inherit;">2021,</em> applying this prospectively.

Any changes in the amount of the actual results and forecasted scenarios could impact the fair value. Significant judgment is employed in determining the appropriateness of the assumptions used in calculating the fair value of the earn-out as of the acquisition date. Accordingly, significant variances between actual and forecasted results or changes in the assumptions can materially impact the amount of contingent consideration expense we record in future periods.

   <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;">2021</em> and <em style="font: inherit;">2020</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;"> April 30, 2021, </em>we had <em style="font: inherit;">two</em> segments &#x2013; RF Connector and Cable Assembly (&#x201c;RF Connector segment&#x201d;) and 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;">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: &quot;Times New Roman&quot;; 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, ROU 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;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><i>Allowance for Doubtful Accounts</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;">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;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><i>Long-Lived Assets Including Goodwill</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;">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;">&#xa0;</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 provides for an earn-out payment of up to $2.4 million, which amount is earned through October 31, 2021. 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 and will continue to be revalued quarterly using a present value approach, and any resulting increase or decrease will be recorded into selling and general expenses. Any changes in the amount of the actual results and forecasted scenarios could impact the fair value. Significant judgment is employed in determining the appropriateness of the assumptions used in calculating the fair value of the earn-out as of the acquisition date. Accordingly, significant variances between actual and forecasted results or changes in the assumptions can materially impact the amount of contingent consideration expense we record in future periods.</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>Income Taxes</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;">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;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;"><b>Overview</b></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;">RF Industries, Ltd. (together with subsidiaries, the &#x201c;Company,&#x201d; we,&#x201d; &#x201c;us,&#x201d; or &#x201c;our&#x201d;) is a national manufacturer and marketer of interconnect products and systems, including coaxial and specialty cables and connectors, fiber optic cables and connectors, and electrical and electronic specialty cables and components. Through our manufacturing and production facilities, we provide a wide selection of interconnect products and solutions primarily to telecommunications carriers and equipment manufacturers, wireless and network infrastructure carriers and manufacturers and to various original equipment manufacturers (&#x201c;OEMs&#x201d;) in several market segments. Since the acquisition of Schrofftech in November 2019, we also manufacture and sell energy-efficient cooling systems and integrated small cell solutions and related components.</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 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;">&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">For the six months ended April 30, 2021, 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 68% of the Company&#x2019;s total sales.&#xa0; Revenues from the RF Connector segment were generated from the sales of RF connector products and cable assemblies and accounted for 32% of total sales for the six months ended April 30, 2021. The RF Connector segment mostly sells standardized products regularly used by customers and, therefore, has a more stable revenue stream.&#xa0; On the other hand, the Custom Cabling segment mostly designs, manufactures, and sells customized cabling and wireless-related equipment under larger purchase orders.&#xa0; Accordingly, the Custom Cabling segment is more dependent upon larger project 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;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In March 2020, the World Health Organization (the &#x201c;WHO&#x201d;) declared coronavirus (&#x201c;COVID-19&#x201d;) a pandemic emergency. The COVID-19 pandemic has negatively impacted regional and global economies, disrupted global supply chains, and created significant volatility and disruption of financial markets. The global impact of the outbreak has been rapidly evolving and certain jurisdictions, including in regions where we or third parties on which we rely have manufacturing facilities, have also reacted by instituting quarantines, restrictions on travel, &#x201c;shelter in place&#x201d; rules, social distancing protocols and restrictions on types of business that may continue to operate. While we have been deemed an &#x201c;essential&#x201d; business, and therefore continued our operations during the quarantines, the impact of the COVID-19 pandemic has affected both our operations and those of our vendors and customers. Our operations in both the 2020 and 2021 periods were negatively affected by partial shutdowns of our facilities (particularly in the Northeast), by changes that we had to make on our operating methods and procedures, and by a fluctuating workforce as at times, some of our employees stayed at home. Many of our customers and vendors have likewise had temporary closures of their facilities and have otherwise been impacted by changes in their industries. As a result, there has been some volatility in the overall demand for our products, and certain costs have increased. We have taken measures to protect the health and safety of our employees, and we continue to work with our customers and vendors to minimize potential disruptions in addressing the challenges posed by this global pandemic.</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 extent of the impact of the COVID-19 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. The outbreak impacted our performance in fiscal year 2020 and for the six months ended April 30, 2021. 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 CARES Act totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;). The funds from the PPP Loans were used to retain employees, maintain payroll and benefits, and make lease and utility payments. Without the PPP Loans, we would have made material reductions in our workforce (particularly at Cables Unlimited). In February 2021, the full $2.8 million of PPP Loans was 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;">&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;; 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;).&#xa0; The ERC is a refundable tax credit against certain employment wages. 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.&#xa0; For the six months ended April 30, 2021, we qualified and filed to claim the ERC and have recorded this as an other receivable.&#xa0; The amount of ERC that we are eligible to receive is $2.4 million, which amount will reduce our labor costs during the six-month period.</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. While we still believe that our existing current assets, the amount of cash we anticipate will be generated from on-going operations, and funds we received from the PPP Loans collectively will be sufficient to fund our anticipated liquidity and capital resource needs for at least twelve months from the date of this filing, there are some uncertainties because of the unknown future impact of the COVID-19 pandemic on our business. Nevertheless, we believe that our existing assets and the cash we expect to generate from operations, including 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 April 30, 2021, we had a total of $14.8 million of cash and cash equivalents compared to a total of $15.8 million of cash and cash equivalents as of October 31, 2020. As of April 30, 2021, we had working capital of $29.2 million and a current ratio of approximately 6.7:1 with current assets of $34.3 million and current liabilities of $5.2 million.</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 April 30, 2021, we had $15.6 million of backlog, compared to $6.3 million as of October 31, 2020. 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 six months ended April 30, 2021, we used $1.4 million of cash in our operating activities despite our net income of $4.5 million. The net outflow of cash was due in part to increased inventory purchases (which increased our inventory balance by $1.0 million), and cash used for other current assets ($2.8 million). The cash used for other current assets represents i) tax payments we made that we are expected to get refunded back of $0.7 million due to the impact of the passage of the Consolidated Appropriations Act (&#x201c;CAA&#x201d;) that allows for PPP loan expenses to be deducted on our tax return, and (ii) employee tax payments for which we will receive future tax credits of $2.4 million. The foregoing cash usage was partially offset by an increase in cash from noncash credits of $0.8 million as a result of the passage of the CAA, $0.4 million from depreciation and amortization, $0.3 million from stock-based compensation expense, and $0.7 million from the collection in accounts receivable.</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;">During the six months ended April 30, 2021, we also spent $0.2 million on capital expenditures. The cash used in operating activities and the amounts spent on capital expenditures were partially offset by $0.5 million of proceeds that we received from the exercise of stock options. As a result of the cash received from the exercise of stock options that partially offset our net cash used in operating and investing activities, our cash and cash equivalent balance decreased by $1.0 million during the April 30, 2021 six-month period.</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 do not anticipate making material additional capital equipment in the next twelve months. In the past, we have financed some of our equipment and furnishings requirements through capital leases. No additional capital equipment purchases have been currently identified that would require significant additional leasing or capital expenditures during the next twelve months.</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 November 2019, we entered into a $5.0 million revolving line of credit that bore interest at a rate of 2.0% plus LIBOR Daily Floating Rate. We never used the line of credit and on December 30, 2020, we closed the line of credit. Accordingly, we currently do not have a credit facility available to us should we need to borrow amounts to fund either our working capital needs or any future unplanned capital expenditures.</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;">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>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Net sales for the three months ended April 30, 2021 (the &#x201c;fiscal 2021 quarter&#x201d;) increased by 6%, or $0.7 million, to $11.1 million as compared to the three months ended April 30, 2020 (the &#x201c;fiscal 2020 quarter&#x201d;) due to an increase in net sales at the Custom Cabling segment. Net sales in the Custom Cabling segment increased by $0.9 million, or 13%, to $7.5 million, compared to $6.6 million in the fiscal 2020 quarter primarily because of increased sales of products to wireless carriers, including fiber optic cables used in the build out of 4G and 5G networks. Net sales for the fiscal 2021 quarter at the RF Connector segment decreased by $0.2 million, or 6%, to $3.6 million as compared to $3.8 million in the fiscal 2020 quarter due primarily to slower project-related deployments in locations like stadiums, large office buildings, and other public use venues.</p>

  <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">Gross profit for the fiscal 2021 quarter increased by $2.2 million to $4.8 million and gross margins increased to 43.1% of sales compared to 24.9% of net sales in the fiscal 2020 quarter due primarily to the ERC that the Company was eligible to claim for the production employees.&#xa0; The ERC refundable employee tax credit reduced our labor costs and thereby increased our gross profits.&#xa0; Excluding the benefit of the ERC, our gross profits for the fiscal 2021 quarter would have been $3.0 million, which is an increase of $0.4 million compared to the fiscal 2020 quarter, and gross margins would have been 27.1%. The increase in gross margins is primarily due to the increase in sales at the Custom Cabling segment in the fiscal 2021 quarter.</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;">Engineering expenses decreased by $0.3 million to $0.2 million in the fiscal 2021 quarter compared to $0.5 million in the fiscal 2020 quarter due to the ERC the Company was eligible to claim for engineering employees. Excluding the benefit of the ERC, engineering expenses would have been $0.4 million, which is a decrease of $0.1 million compared to the fiscal 2020 quarter. This decrease is due to a reduction in engineering marketing personnel, which costs are included in the engineering costs. Engineering expenses represent costs incurred relating to the ongoing research and development of new products.</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;">Selling and general expenses decreased by $0.3 million to $1.9 million (17% of sales) compared to $2.2 million (22% of sales) in the second quarter last year due to the ERC the Company was eligible to claim for the general and administrative employees. Excluding the benefit of the ERC, selling and general expenses would have been $2.5 million (23% of sales), which is an increase of $0.3 million compared to the fiscal 2020 quarter. This increase is primarily due to hiring of additional sales people in the last half of the 2020 fiscal year and in the first quarter of fiscal 2021.</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 February 2021, the full $2.8 million of PPP Loans were forgiven and considered paid in full (including applicable interest), which is reflected as &#x201c;Other Income&#x201d;.</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;">For the fiscal 2021 quarter, the Custom Cabling segment and the RF Connector segment had pretax income of $1.2 million and $1.5 million, respectively, as compared to $0.9 million loss and $0.7 million of income, respectively, for the comparable second quarter last year. The pretax income at both the Custom Cabling and RF Connector segments in the fiscal 2021 quarter was primarily due to the ERC the Company was eligible to claim and the PPP Loan forgiveness.</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;">For the fiscal 2021 and 2020 quarters, we recorded income tax provisions of $648,000 and $3,000, respectively. The effective tax rate was&#xa0;24.2% for the fiscal 2021 quarter, compared to&#xa0;(1.4%) for the fiscal 2020 quarter. The fiscal 2021 quarter&#x2019;s effective tax rate for the three months ended April 30, 2021 is excluding the PPP Loan forgiveness classified in Other Income. The change in effective tax rate for the fiscal 2021 and 2020 quarters was primarily driven by the disproportionate impact of various permanent book-tax differences with respect to our forecasted book income or loss in each period.</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;">For the fiscal 2021 quarter, net income was $4.8 million and fully diluted earnings per share was $0.48 per share, compared to a net loss of $0.2 million and fully diluted loss per share of $0.02 per share for the fiscal 2020 quarter.

The decrease in net sales is attributable to a decrease in net sales at the Custom Cabling segment, which decreased by $1.9 million, or 12%, to $13.9 million compared to $15.8 million in the fiscal 2020 six-month period. The decrease was primarily in our project-based business which resulted from the slowdown in carrier spending in the first quarter of fiscal 2021. Net sales by the Custom Cabling segment increased in the second quarter of fiscal 2021 and such net sales are expected to continue to increase during the remainder of the current fiscal year. Net sales for the fiscal 2021 six-month period at the RF Connector segment increased by $0.2 million, or 2%, to $7.1 million compared to $7.0 million in the fiscal 2020 six-month period.</p>

The increase in gross profit and gross margins was primarily due to the ERC the Company was eligible to claim for production employees. The ERC refundable employee tax credit reduced our labor costs and thereby increased our gross profits. Excluding the benefit of the ERC, our gross profits for the fiscal 2021 six-month period would have been $5.6 million, which is a decrease of $0.2 million compared to the fiscal 2020 six-month period, and gross margins would have been 26.6%.</p>

Excluding the benefit of the ERC, selling and general expenses would have been $5.3 million (25% of sales), which is an increase of $0.4 million compared to the fiscal 2020 six-month period. This increase is primarily due to the hiring of additional sales people in the last half of the 2020 fiscal year and in the first quarter of fiscal 2021.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">For the fiscal 2021 six-month period, pretax income for the Custom Cabling segment and the RF Connector segment was $0.1 million and $1.9 million, respectively, as compared to $1.2 million loss and $1.0 million of income, respectively, for the comparable six-month period last year. The pretax income at the Custom Cabling and RF Connector segments in the six-month period of fiscal 2021 was primarily due to the ERC the Company was eligible to claim and the PPP Loan forgiveness.</p>

  <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">For the fiscal 2021 and 2020 six-month periods, we recorded income tax provisions (benefits) of $454,000 and ($11,000), respectively. The effective tax rate was&#xa0;21.8% for the fiscal 2021 six-month period, compared to&#xa0;6.7% for the fiscal 2020 six-month period. The fiscal 2021 six-month period&#x2019;s effective tax rate is excluding the PPP Loan forgiveness classified in Other Income. The change in effective tax rate for the fiscal 2021 and 2020 six-month periods was primarily driven by the disproportionate impact of various permanent book-tax differences with respect to our forecasted book income or loss in each period.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">We maintain disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) that are designed to assure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC&#x2019;s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.</p>

  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In designing and evaluating the disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide reasonable assurance only of achieving the desired control objectives, and we necessarily are required to apply our judgment in weighing the costs and benefits of possible new or different controls and procedures. Limitations are inherent in all control systems, so no evaluation of controls can provide absolute assurance that all control issues and any fraud have been detected.&#xa0;Because of the inherent limitations, we regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls and increase efficiency, and to maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating activities, and migrating processes.</p>

This pandemic has resulted in a global health crisis that is adversely affecting broader economies, financial markets, and the business environment worldwide. We are monitoring the global impact of the COVID-19 pandemic and taking steps to mitigate the accompanying impact on our business by working with our employees, customers, suppliers, and other stakeholders. The pandemic is adversely affecting, and is expected to continue to adversely affect, certain elements of our business. Portions of our workforce may be unable to work effectively due to illness and containment measures, including quarantines, illness precautions, travel restrictions, and other restrictions. We experienced volatility in customer demand as their businesses were impacted by the pandemic. If the pandemic continues, recurs, or worsens, we may experience additional adverse impacts on our operational and commercial activities, including rising costs, volatility in customer orders and purchases and declines in our collections of accounts receivable. Furthermore, the pandemic has impacted and may further impact the broader U.S. economy, including negatively impacting economic growth, the proper functioning of financial and capital markets and interest rates, all of which could lead to a decline in our net sales. Due to the speed with which the situation is developing, the breadth of its spread and the range of governmental and community reactions thereto, there is uncertainty around its duration, ultimate impact and the timing of recovery. Therefore, the pandemic could lead to an extended disruption of economic activity and the impact on our stock price, access to capital, consolidated results of operations, financial position and cash flows could be material.</p>

   &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 2020, &lt;/em&gt;the World Health Organization (the &#x201c;WHO&#x201d;) declared coronavirus (&#x201c;COVID-&lt;em style="font: inherit;"&gt;19&#x201d;&lt;/em&gt;) a pandemic emergency. 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;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021. &lt;/em&gt;During the periods covered by this report, the operations of our &lt;em style="font: inherit;"&gt;three&lt;/em&gt; subsidiaries in the Northeast were affected as many of our employees stayed at home and as local customers shut down or otherwise delayed, deferred or cancelled 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 CARES Act totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;). See Note &lt;em style="font: inherit;"&gt;13&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: &amp;quot;Times New Roman&amp;quot;; 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. 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.&#160; For the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021, &lt;/em&gt;we qualified and filed to claim the ERC and have recorded this as an other receivable.&#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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;We considered the impact of the COVID-&lt;em style="font: inherit;"&gt;19&lt;/em&gt; related economic slowdown on our evaluation of goodwill and non-amortizable intangibles impairment indicators as of &lt;em style="font: inherit;"&gt; April 30, 2021. &lt;/em&gt;Although &lt;em style="font: inherit;"&gt;no&lt;/em&gt; impairment indicators were identified, it is possible that impairments could emerge as the impact of the crisis becomes clearer, and those impairment losses could be material.&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;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;&lt;b&gt;&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 0pt 0pt 8pt;"&gt;&lt;b&gt;&lt;i&gt;Fair value measurement&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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;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. The accounting principles generally accepted in the United States of America (&#x201c;GAAP&#x201d;) 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 &lt;em style="font: inherit;"&gt;two&lt;/em&gt; types of inputs have created the following fair value hierarchy:&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;Level&#160;&lt;em style="font: inherit;"&gt;1&lt;/em&gt; &#x2013; Quoted prices for identical instruments in active markets;&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;Level&#160;&lt;em style="font: inherit;"&gt;2&lt;/em&gt; &#x2013; Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets;&#160;and&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;In &lt;em style="font: inherit;"&gt; June 2016, &lt;/em&gt;the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;13,&lt;/em&gt; Financial Instruments&#x2014;Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. 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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;In &lt;em style="font: inherit;"&gt; February 2016, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;No.&lt;/em&gt; &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;02,&lt;/em&gt; Leases. This ASU requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the current GAAP. Under ASU &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;02,&lt;/em&gt; lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients. We adopted the standard as of &lt;em style="font: inherit;"&gt; November 1, 2019, &lt;/em&gt;the beginning of our fiscal &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; applying the modified retrospective method.&#160; We elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, allows us to carryforward the historical lease classification.&#160; We elected the policy which allows us to combine the nonlease components with their related lease components rather than separating, and the policy election to keep leases with an initial term of &lt;em style="font: inherit;"&gt;12&lt;/em&gt; months or less off of the balance sheet.&#160; Operating leases are included in our consolidated balance sheet as operating lease right of use (&#x201c;ROU&#x201d;) assets, other current liabilities, and operating lease liabilities. Finance leases are included in finance ROU assets, other current liabilities, and finance lease liabilities on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the duration of the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms &lt;em style="font: inherit;"&gt; may &lt;/em&gt;include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is recognized on the consolidated statements of operations. The adoption of the standard resulted in a material recognition of additional ROU assets and lease liabilities of approximately $2.3 million and $2.4 million, respectively, as of &lt;em style="font: inherit;"&gt; November 1, 2019, &lt;/em&gt;but did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; materially affect our consolidated net loss.&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; April 30, 2021.&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;&lt;em style="font: inherit;"/&gt;&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 2020, &lt;/em&gt;the World Health Organization (the &#x201c;WHO&#x201d;) declared coronavirus (&#x201c;COVID-&lt;em style="font: inherit;"&gt;19&#x201d;&lt;/em&gt;) a pandemic emergency. 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;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021. &lt;/em&gt;During the periods covered by this report, the operations of our &lt;em style="font: inherit;"&gt;three&lt;/em&gt; subsidiaries in the Northeast were affected as many of our employees stayed at home and as local customers shut down or otherwise delayed, deferred or cancelled 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 CARES Act totaling approximately $2.8 million (&#x201c;PPP Loans&#x201d;). See Note &lt;em style="font: inherit;"&gt;13&lt;/em&gt; on discussions of the PPP Loans.&lt;/p&gt;

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.&#160; For the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021, &lt;/em&gt;we qualified and filed to claim the ERC and have recorded this as an other receivable.&#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;In &lt;em style="font: inherit;"&gt; February 2016, &lt;/em&gt;the FASB issued ASU &lt;em style="font: inherit;"&gt;No.&lt;/em&gt; &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;02,&lt;/em&gt; Leases. This ASU requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the current GAAP. Under ASU &lt;em style="font: inherit;"&gt;2016&lt;/em&gt;-&lt;em style="font: inherit;"&gt;02,&lt;/em&gt; lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients. We adopted the standard as of &lt;em style="font: inherit;"&gt; November 1, 2019, &lt;/em&gt;the beginning of our fiscal &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; applying the modified retrospective method.&#160; We elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, allows us to carryforward the historical lease classification.&#160; We elected the policy which allows us to combine the nonlease components with their related lease components rather than separating, and the policy election to keep leases with an initial term of &lt;em style="font: inherit;"&gt;12&lt;/em&gt; months or less off of the balance sheet.&#160; Operating leases are included in our consolidated balance sheet as operating lease right of use (&#x201c;ROU&#x201d;) assets, other current liabilities, and operating lease liabilities. Finance leases are included in finance ROU assets, other current liabilities, and finance lease liabilities on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the duration of the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms &lt;em style="font: inherit;"&gt; may &lt;/em&gt;include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is recognized on the consolidated statements of operations. The adoption of the standard resulted in a material recognition of additional ROU assets and lease liabilities of approximately $2.3 million and $2.4 million, respectively, as of &lt;em style="font: inherit;"&gt; November 1, 2019, &lt;/em&gt;but did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; materially affect our consolidated net loss.&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; April 30, 2021.&lt;/em&gt;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"&gt;&lt;b&gt;Note &lt;em style="font: inherit;"&gt;2&lt;/em&gt; &lt;/b&gt;&#x2013;&lt;b&gt; Business acquisition&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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;On &lt;em style="font: inherit;"&gt; November 4, 2019, &lt;/em&gt;we purchased the business of Schrofftech, a Rhode Island-based manufacturer and marketer of intelligent thermal control systems used by telecommunications companies across the U.S. and Canada, and shrouds for small cell integration and installation. At the closing, in consideration for the Schrofftech business, we paid the sellers $4 million in cash, and, if certain financial targets are met by Schrofftech over a &lt;span style="-sec-ix-hidden:c74202699"&gt;two&lt;/span&gt;-year period, agreed to pay additional cash earn-out payments of up to $2.4 million.&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 acquisition was accounted for as an acquisition of a business in accordance with the acquisition method of accounting. The acquired assets and assumed liabilities have been recorded at their estimated fair values. We determined the estimated fair values with the assistance of appraisals or valuations performed by an independent &lt;em style="font: inherit;"&gt;third&lt;/em&gt;-party specialist. Schrofftech serves the high growth wireless, telecom and cable markets. The Schrofftech business allows us to diversify the types of services provided for our customers in these markets. All manufacturing operations are performed at Schrofftech&#x2019;s facilities in Rhode Island.&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;Although the closing occurred on &lt;em style="font: inherit;"&gt; November 4, 2019, &lt;/em&gt;the acquisition of Schrofftech is deemed to have become effective for financial accounting purposes as of &lt;em style="font: inherit;"&gt; November 1, 2019. &lt;/em&gt;Accordingly, subsequent to &lt;em style="font: inherit;"&gt; November 1, 2019, &lt;/em&gt;Schrofftech&#x2019;s financial results have been included in the results of the Custom Cabling Manufacturing and Assembly segment (&#x201c;Custom Cabling segment&#x201d;) as well as in the consolidated statements of operations. Total costs related to the acquisition of Schrofftech were approximately $151,000 and have been expensed as incurred and categorized in selling and general expenses during periods prior to &lt;em style="font: inherit;"&gt; November 1, 2020.&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;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;text-indent:36pt;"&gt;The purchase agreement for the Schrofftech acquisition provides for earn-out payments of up to $2.4 million, which are 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 and will continue to be revalued quarterly using a present value approach and any resulting increase or decrease will be recorded into selling and general expenses. Any changes in the amount of the actual results and forecasted scenarios could impact the fair value. Significant judgment is employed in determining the appropriateness of the assumptions used in calculating the fair value of the earn-out as of the acquisition date. Accordingly, significant variances between actual and forecasted results or changes in the assumptions can materially impact the amount of contingent consideration expense we record in future periods. In determining the fair value of the earn-out liability as of &lt;em style="font: inherit;"&gt; April 30, 2021, &lt;/em&gt;we used the most recent projections while giving consideration to actual results versus such projections subsequent to &lt;em style="font: inherit;"&gt; April 30, 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 estimate 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).&lt;/p&gt;

Diluted earnings per share is computed by dividing net income (loss) 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; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2020, &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.&#160; Therefore, all outstanding stock options are excluded from the computation of diluted loss per share.&#160; Potentially issuable securities that are out-of-the-money totaled 321,338 and 392,838 shares for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; respectively, and 331,338 and 392,838 shares for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; respectively.

   &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;2021&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2020&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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;Non-employee directors receive a compensation package of $50,000 annually, which is paid &lt;em style="font: inherit;"&gt;one&lt;/em&gt;-half in cash and &lt;em style="font: inherit;"&gt;one&lt;/em&gt;-half through the grant of non-qualified awards. For fiscal &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; compensation payable to non-employee directors was prorated from &lt;em style="font: inherit;"&gt; November 1, 2019 &lt;/em&gt;through &lt;em style="font: inherit;"&gt; August 31, 2020. &lt;/em&gt;On &lt;em style="font: inherit;"&gt; November 4, 2019, &lt;/em&gt;we granted each of our &lt;em style="font: inherit;"&gt;five&lt;/em&gt; non-employee directors 3,270 shares of restricted stock. The number of restricted shares granted to each director was determined by prorating $25,000 for the &lt;em style="font: inherit;"&gt;ten&lt;/em&gt; months ending &lt;em style="font: inherit;"&gt; August 31, 2020 &lt;/em&gt;and dividing by the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average closing stock price ($6.36). These restricted shares vested ratably through &lt;em style="font: inherit;"&gt; August 31, 2020. &lt;/em&gt;As compensation for services to be provided until the &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; annual meeting of stockholders in &lt;em style="font: inherit;"&gt; September 2021, &lt;/em&gt;we granted each of our &lt;em style="font: inherit;"&gt;five&lt;/em&gt; non-employee directors 5,757 shares of restricted stock, which number was determined by dividing $25,000 by the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average closing stock price ($4.34). On &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;a new director joined the Board of Directors. We granted the new director 3,334 shares of restricted stock as payment for the year ending with the &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; annual meeting. The number of restricted stock was determined by prorating $25,000 for the 8.5 months of service upon joining the Board of Directors through the &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; annual meeting and dividing by the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average closing stock price ($5.31).&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"&gt;Non-employee directors who are also a chairperson of a committee of the Board receive additional compensation of $15,000 annually. On &lt;em style="font: inherit;"&gt; June 5, 2020, &lt;/em&gt;the Board of Directors revised the committee chair compensation so that all future compensation from &lt;em style="font: inherit;"&gt; July 1, 2020 &lt;/em&gt;through the next annual meeting of the stockholders will be payable in shares of common stock rather than cash. Shares issued as compensation will be valued at the closing common stock price on the last day of each quarter. Accordingly, on &lt;em style="font: inherit;"&gt; July 31, 2020, &lt;/em&gt;each of the &lt;em style="font: inherit;"&gt;four&lt;/em&gt; committee chairpersons was awarded 279 shares at $4.47 per share. We account for these shares as stock-based compensation. On &lt;em style="font: inherit;"&gt; September 15, 2020, &lt;/em&gt;each of the &lt;em style="font: inherit;"&gt;four&lt;/em&gt; committee chairpersons was awarded 3,454 shares of restricted stock as payment for the $15,000 retainer payable to Chairpersons for the year ending with the &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; annual meeting of stockholders. The number of restricted shares granted to each chairperson was determined by dividing $15,000 by the &lt;em style="font: inherit;"&gt;20&lt;/em&gt;-day average closing stock price ($4.34).&lt;/p&gt;

During the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; stock-based compensation expense totaled $260,000 and $283,000, respectively, and was classified in selling and general expenses.&lt;/p&gt;

The two distributors had accounts receivable balances that accounted for 19% and 14%, respectively, of the total net accounts receivable balance at &lt;em style="font: inherit;"&gt; April 30, 2020. &lt;/em&gt;Although these customers have been on-going major customers of the Company, the written agreements with these customers do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; have any minimum purchase obligations and they could stop buying our products at any time and for any reason. A reduction, delay or cancellation of orders from these customers or the loss of these customers could significantly reduce our future revenues and profits.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"&gt;&lt;b&gt;Note &lt;em style="font: inherit;"&gt;9&lt;/em&gt; &lt;/b&gt;&#x2013;&lt;b&gt; Segment information&lt;/b&gt;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;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;We aggregate operating divisions into &lt;span style="-sec-ix-hidden:c74202969"&gt;two&lt;/span&gt; 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; April 30, 2021, &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 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;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: &amp;quot;Times New Roman&amp;quot;; 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, ROU 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;"&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;All of our operations are conducted in the United States; however, we derive a portion of our revenue from export sales.

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;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 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 provision (benefit) 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: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;"&gt;We recorded income tax provisions of $648,000 and $3,000 for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; respectively. The effective tax rate was&#160;24.2% for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; compared to&#160;(1.4%) for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2020.&lt;/em&gt; For the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2020,&lt;/em&gt; we recorded income tax provisions (benefits) of $454,000 and ($11,000), respectively. The effective tax rate was&#160;21.8% for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2021,&lt;/em&gt; compared to&#160;6.7% for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2020.&lt;/em&gt; The effective tax rates for the &lt;em class="GFJY4-DIN-com-rdg-thunderdome-client-resources-CssResource-html-element-highlighted" style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2021 &lt;/em&gt;are excluding the PPP Loan forgiveness classified in Other Income. The change in effective tax rate for the &lt;em class="GFJY4-DIN-com-rdg-thunderdome-client-resources-CssResource-html-element-highlighted" style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April&#160;&lt;/em&gt;&lt;em style="font: inherit;"&gt;30,&lt;/em&gt; &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; compared to the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; April 30, 2020 &lt;/em&gt;was primarily driven by the disproportionate impact of various permanent book-tax differences with respect to our forecasted book income or loss in each period.&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 had $127,000 and $107,000 of unrecognized tax benefits, inclusive of interest and penalties, as of &lt;em style="font: inherit;"&gt; April 30, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt; October 31, 2020, &lt;/em&gt;respectively. The unrecognized tax benefits, if recognized, would result in a net tax benefit of $33,000 as of &lt;em style="font: inherit;"&gt; April 30, 2021.&lt;/em&gt;&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;In &lt;em style="font: inherit;"&gt; November 2019, &lt;/em&gt;we entered into an agreement for a revolving line of credit (&#x201c;LOC&#x201d;) in the amount of $5.0 million. Amounts outstanding under the LOC shall bear interest at a rate of 2.0% plus LIBOR Daily Floating Rate (&#x201c;base interest rate&#x201d;), with interest payable on the &lt;em style="font: inherit;"&gt;first&lt;/em&gt; day of each month. Borrowings under the LOC are secured by a security interest in certain assets of the Company. The LOC contains certain loan covenants. Failure to maintain the loan covenants &lt;em style="font: inherit;"&gt; may &lt;/em&gt;constitute an event of default, resulting in all outstanding amounts of principal and interest becoming immediately due and payable. All outstanding principal and interest is due and payable on &lt;em style="font: inherit;"&gt; December 1, 2021. &lt;/em&gt;On &lt;em style="font: inherit;"&gt; December 30, 2020, &lt;/em&gt;we closed the LOC with no amounts outstanding.&lt;/p&gt;

The funds from the PPP Loans were used to retain employees, maintain payroll and benefits, and make lease and utility payments. Without the PPP Loans, we would have made material reductions in our workforce (particularly at Cables Unlimited). As of &lt;em style="font: inherit;"&gt; April 30, 2021, &lt;/em&gt;the full amount of the PPP Loans has been forgiven and considered paid in full (including applicable interest).&lt;/p&gt;

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">In <em style="font: inherit;"> March 2020, </em>the World Health Organization (the &#8220;WHO&#8221;) declared coronavirus (&#8220;COVID-<em style="font: inherit;">19&#8221;</em>) a pandemic emergency. The COVID-<em style="font: inherit;">19</em> 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-<em style="font: inherit;">19</em> 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.</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;">The outbreak impacted our performance for the <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> April 30, 2021. </em>During the periods covered by this report, the operations of our <em style="font: inherit;">three</em> subsidiaries in the Northeast were affected as many of our employees stayed at home and as local customers shut down or otherwise delayed, deferred or cancelled orders for our products. Because of the impact that COVID-<em style="font: inherit;">19</em> had on our operations, in <em style="font: inherit;"> May 2020 </em>we applied for and received loans under the Paycheck Protection Program (&#8220;PPP&#8221;) of the CARES Act totaling approximately $2.8 million (&#8220;PPP Loans&#8221;). See Note <em style="font: inherit;">13</em> on discussions of the PPP Loans.</p>

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.&#160; For the <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> April 30, 2021, </em>we qualified and filed to claim the ERC and have recorded this as an other receivable.&#160;</p>

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.

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: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">In <em style="font: inherit;"> June 2016, </em>the Financial Accounting Standards Board (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) <em style="font: inherit;">2016</em>-<em style="font: inherit;">13,</em> Financial Instruments&#8212;Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. 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. We are currently evaluating the impact the adoption of this new standard will have on our consolidated financial statements.</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">In <em style="font: inherit;"> February 2016, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> Leases. This ASU requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the current GAAP. Under ASU <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients. We adopted the standard as of <em style="font: inherit;"> November 1, 2019, </em>the beginning of our fiscal <em style="font: inherit;">2020,</em> applying the modified retrospective method.&#160; We elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, allows us to carryforward the historical lease classification.&#160; We elected the policy which allows us to combine the nonlease components with their related lease components rather than separating, and the policy election to keep leases with an initial term of <em style="font: inherit;">12</em> months or less off of the balance sheet.&#160; Operating leases are included in our consolidated balance sheet as operating lease right of use (&#8220;ROU&#8221;) assets, other current liabilities, and operating lease liabilities. Finance leases are included in finance ROU assets, other current liabilities, and finance lease liabilities on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the duration of the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do <em style="font: inherit;">not</em> provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms <em style="font: inherit;"> may </em>include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is recognized on the consolidated statements of operations. The adoption of the standard resulted in a material recognition of additional ROU assets and lease liabilities of approximately $2.3 million and $2.4 million, respectively, as of <em style="font: inherit;"> November 1, 2019, </em>but did <em style="font: inherit;">not</em> materially affect our consolidated net loss.</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;">In <em style="font: inherit;"> January 2017, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2017</em>-<em style="font: inherit;">04,</em> Intangibles&#8212;Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step <em style="font: inherit;">2</em> 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 <em style="font: inherit;"> November 1, 2020, </em>the beginning of our fiscal <em style="font: inherit;">2021,</em> applying this prospectively. The adoption of the standard did <em style="font: inherit;">not</em> result in an impairment charge as of <em style="font: inherit;"> April 30, 2021.</em></p><p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;"><em style="font: inherit;"/></p>

At the closing, in consideration for the Schrofftech business, we paid the sellers $4 million in cash, and, if certain financial targets are met by Schrofftech over a <span style="-sec-ix-hidden:c74202699">two</span>-year period, agreed to pay additional cash earn-out payments of up to $2.4 million.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The acquisition was accounted for as an acquisition of a business in accordance with the acquisition method of accounting.

Schrofftech serves the high growth wireless, telecom and cable markets. The Schrofftech business allows us to diversify the types of services provided for our customers in these markets. All manufacturing operations are performed at Schrofftech&#8217;s facilities in Rhode Island.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>

Total costs related to the acquisition of Schrofftech were approximately $151,000 and have been expensed as incurred and categorized in selling and general expenses during periods prior to <em style="font: inherit;"> November 1, 2020.</em></p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">The purchase agreement for the Schrofftech acquisition provides for earn-out payments of up to $2.4 million, which are earned through <em style="font: inherit;"> October 31, 2021. </em>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 and will continue to be revalued quarterly using a present value approach and any resulting increase or decrease will be recorded into selling and general expenses. Any changes in the amount of the actual results and forecasted scenarios could impact the fair value. Significant judgment is employed in determining the appropriateness of the assumptions used in calculating the fair value of the earn-out as of the acquisition date. Accordingly, significant variances between actual and forecasted results or changes in the assumptions can materially impact the amount of contingent consideration expense we record in future periods. In determining the fair value of the earn-out liability as of <em style="font: inherit;"> April 30, 2021, </em>we used the most recent projections while giving consideration to actual results versus such projections subsequent to <em style="font: inherit;"> April 30, 2021.</em></p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) 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> and <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> April 30, 2020, </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.&#160; Therefore, all outstanding stock options are excluded from the computation of diluted loss per share.&#160; Potentially issuable securities that are out-of-the-money totaled 321,338 and 392,838 shares for the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> April 30, 2021 </em>and <em style="font: inherit;">2020,</em> respectively, and 331,338 and 392,838 shares for the <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> April 30, 2021 </em>and <em style="font: inherit;">2020,</em> respectively. These shares 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;">2021</em> and <em style="font: inherit;">2020</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>

For fiscal <em style="font: inherit;">2020,</em> compensation payable to non-employee directors was prorated from <em style="font: inherit;"> November 1, 2019 </em>through <em style="font: inherit;"> August 31, 2020. </em>On <em style="font: inherit;"> November 4, 2019, </em>we granted each of our <em style="font: inherit;">five</em> non-employee directors 3,270 shares of restricted stock. The number of restricted shares granted to each director was determined by prorating $25,000 for the <em style="font: inherit;">ten</em> months ending <em style="font: inherit;"> August 31, 2020 </em>and dividing by the <em style="font: inherit;">20</em>-day average closing stock price ($6.36). These restricted shares vested ratably through <em style="font: inherit;"> August 31, 2020. </em>As compensation for services to be provided until the <em style="font: inherit;">2021</em> annual meeting of stockholders in <em style="font: inherit;"> September 2021, </em>we granted each of our <em style="font: inherit;">five</em> non-employee directors 5,757 shares of restricted stock, which number was determined by dividing $25,000 by the <em style="font: inherit;">20</em>-day average closing stock price ($4.34). On <em style="font: inherit;"> December 31, 2020, </em>a new director joined the Board of Directors. We granted the new director 3,334 shares of restricted stock as payment for the year ending with the <em style="font: inherit;">2021</em> annual meeting. The number of restricted stock was determined by prorating $25,000 for the 8.5 months of service upon joining the Board of Directors through the <em style="font: inherit;">2021</em> annual meeting and dividing by the <em style="font: inherit;">20</em>-day average closing stock price ($5.31).</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">Non-employee directors who are also a chairperson of a committee of the Board receive additional compensation of $15,000 annually. On <em style="font: inherit;"> June 5, 2020, </em>the Board of Directors revised the committee chair compensation so that all future compensation from <em style="font: inherit;"> July 1, 2020 </em>through the next annual meeting of the stockholders will be payable in shares of common stock rather than cash. Shares issued as compensation will be valued at the closing common stock price on the last day of each quarter. Accordingly, on <em style="font: inherit;"> July 31, 2020, </em>each of the <em style="font: inherit;">four</em> committee chairpersons was awarded 279 shares at $4.47 per share. We account for these shares as stock-based compensation. On <em style="font: inherit;"> September 15, 2020, </em>each of the <em style="font: inherit;">four</em> committee chairpersons was awarded 3,454 shares of restricted stock as payment for the $15,000 retainer payable to Chairpersons for the year ending with the <em style="font: inherit;">2021</em> annual meeting of stockholders. The number of restricted shares granted to each chairperson was determined by dividing $15,000 by the <em style="font: inherit;">20</em>-day average closing stock price ($4.34).</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">We aggregate operating divisions into <span style="-sec-ix-hidden:c74202969">two</span> 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;"> April 30, 2021, </em>we had <em style="font: inherit;">two</em> segments &#8211; RF Connector and Cable Assembly (&#8220;RF Connector segment&#8221;) and 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;">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: &quot;Times New Roman&quot;; 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, ROU 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;">&#160;</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> and <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> April 30, 2021 </em>and <em style="font: inherit;">2020</em> (in thousands):</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;text-indent:36pt;">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 provision (benefit) 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.</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;">We recorded income tax provisions of $648,000 and $3,000 for the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> April&#160;</em><em style="font: inherit;">30,</em> <em style="font: inherit;">2021</em> and <em style="font: inherit;">2020,</em> respectively.

   <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;">We had $127,000 and $107,000 of unrecognized tax benefits, inclusive of interest and penalties, as of <em style="font: inherit;"> April 30, 2021 </em>and <em style="font: inherit;"> October 31, 2020, </em>respectively.

Because of the impact that COVID-<em style="font: inherit;">19</em> had on our operations, in <em style="font: inherit;"> May 2020 </em>we applied for and received loans under the Paycheck Protection Program (&#8220;PPP&#8221;) of the CARES Act totaling approximately $2.8 million (&#8220;PPP Loans&#8221;). See Note <em style="font: inherit;">13</em> on discussions of the PPP Loans.</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">In <em style="font: inherit;"> June 2016, </em>the Financial Accounting Standards Board (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) <em style="font: inherit;">2016</em>-<em style="font: inherit;">13,</em> Financial Instruments&#8212;Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. 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. We are currently evaluating the impact the adoption of this new standard will have on our consolidated financial statements.</p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 36pt;">In <em style="font: inherit;"> February 2016, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> Leases. This ASU requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the current GAAP. Under ASU <em style="font: inherit;">2016</em>-<em style="font: inherit;">02,</em> lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients. We adopted the standard as of <em style="font: inherit;"> November 1, 2019, </em>the beginning of our fiscal <em style="font: inherit;">2020,</em> applying the modified retrospective method.&#160; We elected the package of practical expedients permitted under the transition guidance with the new standard, which among other things, allows us to carryforward the historical lease classification.&#160; We elected the policy which allows us to combine the nonlease components with their related lease components rather than separating, and the policy election to keep leases with an initial term of <em style="font: inherit;">12</em> months or less off of the balance sheet.&#160; Operating leases are included in our consolidated balance sheet as operating lease right of use (&#8220;ROU&#8221;) assets, other current liabilities, and operating lease liabilities. Finance leases are included in finance ROU assets, other current liabilities, and finance lease liabilities on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the duration of the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do <em style="font: inherit;">not</em> provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms <em style="font: inherit;"> may </em>include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term and is recognized on the consolidated statements of operations. The adoption of the standard resulted in a material recognition of additional ROU assets and lease liabilities of approximately $2.3 million and $2.4 million, respectively, as of <em style="font: inherit;"> November 1, 2019, </em>but did <em style="font: inherit;">not</em> materially affect our consolidated net loss.</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;">In <em style="font: inherit;"> January 2017, </em>the FASB issued ASU <em style="font: inherit;">No.</em> <em style="font: inherit;">2017</em>-<em style="font: inherit;">04,</em> Intangibles&#8212;Goodwill and Other, which simplifies the subsequent measurement of goodwill by eliminating Step <em style="font: inherit;">2</em> 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 <em style="font: inherit;"> November 1, 2020, </em>the beginning of our fiscal <em style="font: inherit;">2021,</em> applying this prospectively. The adoption of the standard did <em style="font: inherit;">not</em> result in an impairment charge as of <em style="font: inherit;"> April 30, 2021.</em></p><span></span>
