Note 5. Revenue

Revenue Recognition

Net sales include products and shipping and handling charges. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The Company recognizes revenue by transferring the promised products to the customer, with substantially all revenue recognized at the point in time the customer obtains control of the products. The Company recognizes revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. The majority of the Company’s contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.

Disaggregation of Revenue

The Company allocates sales from external customers to geographic areas based on the location to which the product is transported. Sales outside the United States are principally to countries in the Caribbean, Canada, Central and South America.

Revenues related to the following geographic areas were as follows for the three and nine months ended:

Broadband Service Providers are made up of Community Broadband, which includes local and regional telecom companies, utilities, municipalities and alternative carriers, multiple system operators (“MSO’s, or Cable TV”), which are also referred to as Tier 2 and Tier 3 customers; National Carriers, which includes large national and global wireline and wireless providers also referred to as Tier 1’s; and International customers.

Accounts Receivable

Credit is extended based on the evaluation of a customer’s financial condition, and collateral is generally not required. Accounts that are outstanding longer than the contractual payment terms are considered past due. The Company writes off accounts receivable when they become uncollectible; payments subsequently received on such receivables are credited to the allowance for doubtful accounts. As of June 30, 2021 and September 30, 2020, the balance in the allowance for doubtful accounts was $79,473 and $289,085, respectively. The allowance for doubtful accounts decreased by the amount recovered during the three months ended March 31, 2021 on an account previously reserved.
