Fair Value Measurements

The carrying amounts reported in the condensed consolidated balance sheets as of January 31, 2024 and October 31, 2023 for cash, trade accounts receivable, income taxes refundable – current, other receivables, current installments of long-term debt, accounts payable and accrued expenses, accrued compensation and payroll taxes, and income taxes payable approximate fair value because of the short maturity of these instruments. The carrying value of the Company’s note payable, revolver – noncurrent, and long-term debt, excluding current installments, approximates fair value because the interest rates vary with the market. Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Earnings Per Share [Text Block]

(9)

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:

	Three months ended
	January 31,
	2024			2023
Net income (loss) (numerator)	$	(1,425,274	)	$	809,984
Shares (denominator)		7,751,116			7,893,194
Basic and diluted net income (loss) per share	$	(0.18	)	$	0.10

Weighted average unvested shares for the three months ended January 31, 2024 totaling 142,565, while issued and outstanding, were not included in the computation of basic and diluted net loss per share for the three months ended January 31, 2024 (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 that period).

Stock Incentive Plans and Other Share‑Based Compensation

As of January 31, 2024, there were approximately 396,000 remaining shares available for grant under the Optical Cable Corporation 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 ended January 31, 2024 and 2023 was $159,151 and $135,041, respectively. Share-based compensation expense is entirely related to expense recognized in connection with the vesting of restricted stock awards or other stock awards.

Stock Compensation

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.

Restricted stock award activity during the three months ended January 31, 2024 consisted of restricted shares withheld for taxes in connection with the vesting of restricted shares totaling 40,324 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. The Company accrued $107,661 as of January 31, 2024 related to the surrender of shares by participants to pay for withholding taxes on shares that vested on January 31, 2024.

As of January 31, 2024, 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 1.2 year weighted-average period is approximately $356,000.

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 $89,325 as of January 31, 2024 and $110,336 as of October 31, 2023.

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 $291,823 as of January 31, 2024 and $252,264 as of October 31, 2023.

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.

Disaggregation of Revenue

The following table presents net sales attributable to the United States and all other countries in total for the three months ended January 31, 2024 and 2023:

	Three months ended
	January 31,
	2024		2023
United States	$	11,969,555	$	14,578,085
Outside the United States		2,885,210		3,705,590
Total net sales	$	14,854,765	$	18,283,675

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

In November 2023, the FASB issued Accounting Standards Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 requires enhanced disclosures about significant segment expenses and enhanced disclosures in interim periods. The guidance in ASU 2023-07 will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023 and interim reporting periods in fiscal years beginning after December 31, 2024, with early adoption permitted. The Company is currently evaluating the impact ASU 2023-09 will have on its financial statement disclosures.

In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”).

ASU 2023-09 is effective for public companies starting in annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact ASU 2023-09 will have on its 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.

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 January 31, 2024 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 ended January 31, 2024 and 2023, 15.5% and 14.8%, respectively, of consolidated net sales were attributable to one national distributor customer.

The Company has a single reportable segment for purposes of segment reporting.

Leases

The Company has an operating lease agreement for approximately 34,000 square feet of office, manufacturing and warehouse space in Plano, Texas (near Dallas). The lease term expires on November 30, 2024.

The Company has an operating lease agreement for approximately 36,000 square feet of warehouse space in Roanoke, Virginia. During the first quarter of fiscal year 2023, the lease term was extended for an additional three years. The new expiration date is April 30, 2026.

The Company also leases certain office equipment under operating leases with initial 60 month terms. The lease terms expire in February and April of 2025.

OCC leases printers that are used in the Roanoke, Virginia manufacturing facility. The lease term expires on August 22, 2026. The right-of-use asset is being amortized on a straight line basis over seven years. When the lease term ends, the remaining net book value of the right-of-use asset will be classified as property and equipment.

The Company’s lease contracts may include options to extend or terminate the leases. 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 $502,998 and $596,578 were included in other assets at January 31, 2024 and October 31, 2023, respectively.

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”) and a Revolving Credit Master Promissory Note and related Loan and Security Agreement (collectively, the “Revolver”).

The Virginia Real Estate Loan is with Northeast Bank and is payable in monthly installments of principal and interest. Principal is calculated using the unpaid balance of the loan and a two hundred forty (240) month amortization schedule. Interest is computed on the aggregate principal balance outstanding at a rate equal to the Prime Rate, adjusted monthly on the fifth day of each calendar month in accordance with changes to the Prime Rate, provided, however, that the interest rate is never less than 8.5% per annum on the basis of a 360-day year times the actual number of days elapsed. The maturity date is May 5, 2026.

The Loan remains generally secured by a first lien deed of trust on the land and buildings at the Company’s headquarters and manufacturing facilities located in Roanoke, Virginia. All other terms of the Virginia Real Estate Loan remain unaltered and remain in full force and effect.

The Company had an outstanding balance on its Virginia Real Estate Loan of $2.7 million, as of January 31, 2024 and October 31, 2023.

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) $1,150,000.

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 January 31, 2024, the Revolver accrued interest at the prime lending rate plus 1.5% (resulting in a 10.0% rate at January 31, 2024). The termination date of the Revolver is July 24, 2025 and 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 January 31, 2024, the Company had $7.5 million of outstanding borrowings on its Revolver and $2.3 million in available credit. As of October 31, 2023, the Company had $8.3 million of outstanding borrowings on its Revolver and $2.6 million in available credit.

Other Information At the end of December 2022, an office building and its contents at the Company’s Asheville facilities sustained water damage resulting from a burst pipe in the sprinkler system, likely due to extreme low temperatures in the area during the days leading up to the event. This office building is separate from the Company’s manufacturing building which houses its manufacturing operations and certain offices at the same location. There was no significant impact to the Company’s operations. The Company has insurance coverage for the office building, its contents and certain business expenses to cover the losses incurred. During the first quarter of fiscal year 2024, the Company included $235,000 of insurance proceeds in other income (expense), net as a gain on insurance proceeds for damage to property and equipment on the Company’s condensed consolidated statement of operations. To the extent the Company incurs expenses in future periods to restore, repair or replace damaged assets, it may recognize offsetting losses in those future periods. At this time, the Company does not expect any future restoration and repair costs to exceed any insurance proceeds.
