Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent.

General

The accompanying unaudited condensed consolidated financial statements of Optical Cable Corporation and its subsidiaries (collectively, the “Company” or “OCC^®”) have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to Form 10‑Q and Regulation S‑X. Accordingly, they do not include all of the information and notes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all material adjustments considered necessary for a fair presentation have been included. Operating results for the nine months ended July 31, 2021 are not necessarily indicative of the results for the fiscal year ending October 31, 2021 because the following items, among other things, may impact those results: impacts of the COVID-19 pandemic including (but not limited to) related government and private industry mandates in the areas of the world in which we operate, changes in market conditions, seasonality, changes in technology, competitive conditions, timing of certain projects and purchases by key customers, significant variations in sales resulting from high volatility and timing of large sales orders among a limited number of customers in certain markets, ability of management to execute its business plans, continued ability to maintain and/or secure future debt and/or equity financing to adequately finance ongoing operations; as well as other variables, uncertainties, contingencies and risks set forth as risks in the Company’s Annual Report on Form 10‑K for the fiscal year ended October 31, 2020 (including those set forth in the “Forward-Looking Information” section), or as otherwise set forth in other filings by the Company as variables, contingencies and/or risks possibly affecting future results. The unaudited condensed consolidated financial statements and condensed notes are presented as permitted by Form 10‑Q and do not contain certain information included in the Company’s annual consolidated financial statements and notes. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10‑K for the fiscal year ended October 31, 2020.

Stock Incentive Plans and Other Share‑Based Compensation

As of July 31, 2021, there were approximately 333,000 remaining shares available for grant under the Optical Cable Corporation 2017 Stock Incentive Plan (“2017 Plan”).

Share-based compensation expense for employees, a consultant and non-employee Directors recognized in the condensed consolidated statements of operations for the three months and nine months ended July 31, 2021 was $75,087 and $217,454, respectively, and for the three months and nine months ended July 31, 2020 was $40,605 and $101,638, respectively. Share-based compensation expense is entirely related to expense recognized in connection with the vesting of restricted stock awards or other stock awards. No restricted stock awards have been granted to employees since fiscal year 2018.

Restricted and Other Stock Awards

The Company has granted, and anticipates granting from time to time, restricted stock awards subject to approval by the Compensation Committee of the Board of Directors. Since fiscal year 2004, the Company has exclusively used restricted stock awards for all share-based compensation of employees and consultants, and restricted stock awards or stock awards to non-employee members of the Board of Directors.

During the three months ended July 31, 2021, OCC granted restricted stock awards totaling 30,055 shares to non-employee Directors under the 2017 Plan. The shares are subject to a one-year vesting period and are part of the non-employee Directors’ annual compensation for service on the Board of Directors. The Company recorded expense totaling $9,242 and $81,076, respectively, during the three months and nine months ended July 31, 2021 and recorded expense totaling $35,917 and $95,245, respectively, during the three and nine months ended July 31, 2020 related to the grants to non-employee Directors.

Restricted stock award activity during the nine months ended July 31, 2021 consisted of restricted stock grants totaling 30,055 and restricted shares forfeited totaling 971 shares. OCC restricted stock grants provide the participant with the option to surrender shares to pay for withholding tax obligations resulting from any vesting restricted shares, or to pay cash to the Company or taxing authorities in the amount of the withholding taxes owed on the value of any vesting restricted shares in order to avoid surrendering shares.

As of July 31, 2021, the estimated amount of compensation cost related to unvested equity-based compensation awards in the form of service-based and operational performance-based shares that the Company will recognize over a 1.6 year weighted-average period is approximately $285,000.

Long-term Debt and Notes Payable

The Company has credit facilities consisting of a real estate term loan, as amended and restated (the “Virginia Real Estate Loan”), a supplemental real estate term loan, as amended and restated (the “North Carolina Real Estate Loan”) and a Revolving Credit Master Promissory Note and related agreements (collectively, the “Revolver”).

Effective July 15, 2021, Northeast Bank purchased both the Virginia Real Estate Loan and the North Carolina Real Estate Loan from Pinnacle Bank (“Pinnacle”), with all terms of the real estate loans remaining the same. The real estate loans have a fixed interest rate of 3.95% and are secured by a first lien deed of trust on the Company’s real property.

Long-term debt as of July 31, 2021 and October 31, 2020 consists of the following:

	July 31,		October 31,
	2021		2020
Virginia Real Estate Loan ($6.5 million original principal) payable in monthly installments of $31,812, including interest (at 3.95%), with final payment of $3,318,029 due May 1, 2024	$	3,954,778	$	4,119,850

Total long-term debt		4,932,252		5,165,566
Less current installments		321,583		312,109
Long-term debt, excluding current installments	$	4,610,669	$	4,853,457

In fiscal year 2020, the Company obtained an unsecured Paycheck Protection Program loan (“PPP Loan”) implemented by the United States Small Business Administration (“SBA”) through Pinnacle in the amount of $4,981,400. The loan was made through the SBA as part of the PPP under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The interest rate was fixed at 1.00% per year, and the Company accrued interest of $60,323 on the PPP Loan. Under the CARES Act and The Paycheck Protection Program Flexibility Act of 2020, all or a portion of the loan (principal and interest) would be forgiven if certain requirements were met. The Company met these requirements and applied for forgiveness of the entire balance of the loan (including accrued interest), submitting an application to Pinnacle on February 22, 2021. On July 1, 2021, the SBA forgave the entire balance of the PPP Loan (including accrued interest). As a result, the Company recognized a gain on the extinguishment of debt totaling $5,041,723 (principal amount of $4,981,400 plus accrued interest totaling $60,323) in the third quarter of fiscal year 2021.

The Revolver with North Mill Capital LLC (now doing business as SLR Business Credit, “SLR”) provides the Company with one or more advances in an amount up to: (a) 85% of the aggregate outstanding amount of eligible accounts (the “eligible accounts loan value”); plus (b) the lowest of (i) an amount up to 35% of the aggregate value of eligible inventory, (ii) $5,000,000, and (iii) an amount not to exceed 100% of the then outstanding eligible accounts loan value; minus (c) $1,500,000.

The maximum aggregate principal amount subject to the Revolver is $18,000,000. Interest accrues on the daily balance at the per annum rate of 1.5% above the Prime Rate in effect from time to time, but not less than 4.75% (the “Applicable Rate”). In the event of a default, interest may become 6.0% above the Applicable Rate. As of July 31, 2021, the Revolver accrued interest at the prime lending rate plus 1.5% (resulting in a 4.75% rate at July 31, 2021). The initial term of the Revolver is three years, with a termination date of July 24, 2023. After the initial term and unless otherwise terminated, the loan may be extended in one year periods subject to the agreement of SLR.

The Revolver is secured by all of the following assets: properties, rights and interests in property of the Company whether now owned or existing, or hereafter acquired or arising, and wherever located; all accounts, equipment, commercial tort claims, general intangibles, chattel paper, inventory, negotiable collateral, investment property, financial assets, letter-of-credit rights, supporting obligations, deposit accounts, money or assets of the Company, which hereafter come into the possession, custody, or control of SLR; all proceeds and products, whether tangible or intangible, of any of the foregoing, including proceeds of insurance covering any or all of the foregoing; any and all tangible or intangible property resulting from the sale, lease, license or other disposition of any of the foregoing, or any portion thereof or interest therein, and all proceeds thereof; and any other assets of the Company which may be subject to a lien in favor of SLR as security for the obligations under the Loan Agreement.

As of July 31, 2021 the Company had $5.6 million of outstanding borrowings on its Revolver and $2.2 million in available credit. As of October 31, 2020, the Company had $5.0 million of outstanding borrowings on its Revolver and $1.6 million in available credit.

The Company also leases certain equipment under operating leases with initial 60 month terms.

The Company’s lease contracts may include options to extend or terminate the lease. The Company exercises judgment to determine the term of those leases when such options are present and include such options in the calculation of the lease term when it is reasonably certain that it will exercise those options.

The Company includes contract lease components in its determination of lease payments, while non-lease components of the contracts, such as taxes, insurance, and common area maintenance, are expensed as incurred. At commencement, right-of-use assets and lease liabilities are measured at the present value of future lease payments over the lease term. The Company uses its incremental borrowing rate based on information available at the time of lease commencement to measure the present value of future payments.

Operating lease expense is recognized on a straight-line basis over the lease term. Short term leases with an initial term of 12 months or less are expensed as incurred. The Company’s short term leases have month-to-month terms.

Operating lease right-of-use assets of $1,117,247 and $1,265,194 were included in other assets at July 31, 2021 and October 31, 2020, respectively.

Net Income (Loss) Per Share

Basic net income (loss) per share excludes dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the net income (loss) of the Company.

The following is a reconciliation of the numerators and denominators of the net income (loss) per share computations for the periods presented:

Weighted average unvested shares for the three months and nine months ended July 31, 2020 totaling 173,115 and 125,877, while issued and outstanding, were not included in the computation of basic and diluted net loss per share for the three months and nine months ended July 31, 2020 (because to include such shares would have been antidilutive, or in other words, to do so would have reduced the net loss per share for those periods).

Segment Information and Business and Credit Concentrations

The Company provides credit, in the normal course of business, to various commercial enterprises, governmental entities and not‑for‑profit organizations. Concentration of credit risk with respect to trade receivables is normally limited due to the Company’s large number of customers. The Company also manages exposure to credit risk through credit approvals, credit limits and monitoring procedures. Management believes that credit risks as of July 31, 2021 have been adequately provided for in the condensed consolidated financial statements. The Company includes all entities under common ownership for the purpose of calculating business concentrations.

For the three months and nine months ended July 31, 2021, 20.9% and 20.0% of consolidated net sales were attributable to one national distributor customer. For the three months and nine months ended July 31, 2020, 16.1% and 13.7% of consolidated net sales was attributable to one national distributor customer.

Revenue from Contract with Customer [Text Block]

(11)

Revenue Recognition

Revenues consist of product sales that are recognized at a specific point in time under the core principle of recognizing revenue when control transfers to the customer. The Company considers customer purchase orders, governed by master sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. For each contract, the promise to transfer the control of the products, each of which is individually distinct, is considered to be the identified performance obligation. The Company evaluates each customer’s credit risk when determining whether to accept a contract.

In determining transaction prices, the Company evaluates whether fixed order prices are subject to adjustment to determine the net consideration to which the Company expects to be entitled. Contracts do not include financing components, as payment terms are generally due 30 to 90 days after shipment. Taxes assessed by governmental authorities and collected from the customer including, but not limited to, sales and use taxes and value-added taxes, are not included in the transaction price and are not included in net sales.

The Company recognizes revenue at the point in time when products are shipped or delivered from its manufacturing facility to its customer, in accordance with the agreed upon shipping terms. Since the Company typically invoices the customer at the same time that performance obligations are satisfied, no contract assets are recognized. The Company’s contract liability represents advance consideration received from customers prior to transfer of the product. This liability was $108,552 as of July 31, 2021 and $63,283 as of October 31, 2020.

Sales to certain customers are made pursuant to agreements that provide price adjustments and limited return rights with respect to the Company’s products. The Company maintains a reserve for estimated future price adjustment claims, rebates and returns as a refund liability. The Company’s refund liability was $131,702 as of July 31, 2021 and $119,989 as of October 31, 2020.

The Company offers standard product warranty coverage which provides assurance that its products will conform to contractually agreed-upon specifications for a limited period from the date of shipment. Separately-priced warranty coverage is not offered. The warranty claim is generally limited to a credit equal to the purchase price or a promise to repair or replace the product for a specified period of time at no additional charge.

The Company accounts for shipping and handling activities related to contracts with customers as a cost to fulfill its promise to transfer control of the related product. Shipping and handling costs are included in selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations.

The Company incurs sales commissions to acquire customer contracts that are directly attributable to the contracts. The commissions are expensed as selling expenses during the period that the related products are transferred to customers.

Employee Retention Tax Credit

The Employee Retention Tax Credit (“ERTC”), created in the March 2020 CARES Act and then subsequently amended by the Consolidated Appropriation Act (“CAA”) of 2021 and the American Rescue Plan Act (“ARPA”) of 2021, is a refundable payroll credit for qualifying businesses keeping employees on their payroll during the COVID-19 pandemic. Under CAA and ARPA amendments, employers can claim a refundable tax credit against the employer share of social security tax equal to 70% of the qualified wages (including certain health care expenses) paid to employees after December 31, 2020 through December 31, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021 so the maximum ERTC available is $7,000 per employee per calendar quarter.

OCC is an eligible small employer under the gross receipts decline test when comparing the first calendar quarter of 2021 to the same quarter in calendar year 2019, which qualified the Company to claim ERTC in both the first and second calendar quarters of 2021 under the amended ERTC program. The Company qualified for a refundable payroll tax credit totaling $3,375,815 during its second fiscal quarter and $964,550 during its third fiscal quarter of 2021 for a total of $4,340,365. The $964,550 is included in other income on the Company’s condensed consolidated statement of operations for the three months ended July 31, 2021, and the $4,340,365 is included in other income on the Company’s condensed consolidated statement of operations for the nine months ended July 31, 2021. The Company was able to use $710,303 of the ERTC during the third quarter of fiscal year 2021 to offset payroll taxes in the months of May and June 2021. The remaining $3,630,062 of the ERTC is included in other receivables on the Company’s condensed consolidated balance sheet as of July 31, 2021.

Commitments and Contingencies Disclosure [Text Block]

Contingencies

From time to time, the Company is involved in various claims, legal actions and regulatory reviews arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s financial position, results of operations or liquidity.

The COVID-19 pandemic has had a significant impact on businesses and individuals in the United States and globally. Actions taken by governments and private industry to limit the spread of the disease (including its variant strains) have resulted in an unprecedented disruption of normal activities as businesses have been forced to shut down or operate on a limited basis. The Company is obligated and continues to operate during the COVID-19 pandemic because the Company’s workforce is classified a “Defense Industrial Base Essential Critical Infrastructure Workforce” under guidelines from the U.S. Department of Defense and an “Essential Critical Infrastructure Workforce” under guidelines by the U.S. Department of Homeland Security, Cybersecurity and Infrastructure Security Agency (CISA).

In response to the continued uncertainty of the impact of COVID-19, the Company continues to maintain certain protocols at each of its facilities including: limiting business travel and face-to-face meetings, having a portion of its non-manufacturing employees work remotely, and implementing strict social distancing, symptom self-assessments and mask protocols within its facilities.

The extent to which the COVID-19 pandemic will affect the Company in the future will depend on ongoing developments, which are highly uncertain and cannot be reasonably predicted, including, but not limited to, the duration and severity of the outbreak, the timing and extent of the easing of restrictions on businesses and individuals, the timing of recovery in certain of the Company’s markets, the potential for a resurgence of the virus (including its variant strains), as well as a variety of other unknowable factors. The longer the various impacts of COVID-19 persist, the greater the potential negative financial effects on the Company.

ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The adoption of ASU 2019-12 is not expected to have a material impact on the Company’s results of operations, financial position or liquidity or its related financial statement disclosures.

There are no other new accounting standards issued, but not yet adopted by the Company, which are expected to materially impact the Company’s financial position, operating results or financial statement disclosures.
