​ Significant Judgments Under Topic 606 “Revenue from Contracts with Customers”, we use judgments that could potentially impact both the timing of our satisfaction of performance obligations and our determination of transaction prices used in determining revenue recognized by major product line. Such judgments include considerations in determining our transaction prices and when our performance obligations are satisfied for our standard product sales. For our Engineering Services, performance obligations are recognized over time using the input method and the estimated costs to complete each project are considered significant judgments. Performance Obligations Revenues from our performance obligations are typically satisfied at a point-in-time for Smart Glasses, Waveguides and Display Engines, and our OEM Products, which are recognized when the customer obtains control and ownership, which is generally upon shipment. The Company considers shipping and handling activities performed to be fulfillment activities and not a separate performance obligation. The Company also records revenue for performance obligations relating to our Engineering Services over time by using the input method measuring progress toward satisfying the performance obligations. Satisfaction of our performance obligations related to our Engineering Services is measured by the Company’s costs incurred as a percentage of total expected costs to project completion as the inputs of actual costs incurred by the Company are directly correlated with progress toward completing the contract. As such, the Company believes that our methodologies for recognizing revenue over time for our Engineering Services correlate directly with the transfer of control of the underlying assets to our customers. Our standard product sales include a twelve (12) month assurance-type product warranty. In the case of certain of our OEM products and waveguide sales, some include a standard product warranty of up to eighteen (18) months to allow distribution channels to offer the end customer a full twelve (12) months of coverage. We offer extended warranties to customers, which extend the standard product warranty on product sales for an additional twelve (12) month period. All revenue related to extended product warranty sales is deferred and recognized over the extended warranty period. Our Engineering Services contracts vary from contract to contract but typically include payment terms of Net 30 days from the date of billing, subject to an agreed upon customer acceptance period. As of December 31, 2023 and 2022, there were no outstanding performance obligations remaining for extended warranties. The following table presents a summary of the Company’s net sales by revenue recognition method as a percentage of total net sales: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | % of Total Net Sales |
​ | ​ | 2023 |  | 2022 |  | 2021 | ​
Point-in-Time |  | 89 | % | 89 | % | 97 | %
Over Time – Input Method |  | 11 | % | 11 | % | 3 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Total |  | 100 | % | 100 | % | 100 | %
​ Remaining Performance Obligations As of December 31, 2023, the Company had $2,929,709 of remaining performance obligations under three current waveguide development projects, which represents the remainder of transaction prices totaling $3,637,240 under these development agreements, which commenced in 2023, less revenue recognized under percentage of completion to date. The Company expects to recognize the remaining revenue related to these projects, based upon expected due dates, of 66% in 2024 and 34% in 2025. Revenues earned less amounts invoiced at December 31, 2023, in the amount of $165,771 are reflected as Accrued Revenues in Excess of Billings in the accompanying Consolidated Balance Sheet. As of December 31, 2022, the Company had approximately $187,000 of remaining performance obligations under a current waveguide development project, which represents the remainder of the total transaction price of approximately $896,000 under this development agreement, less revenue recognized under percentage of completion to date. The Company did recognize the remaining revenue related to this project in the first quarter of 2023. Revenues earned less amounts invoiced at December 31, 2022 in the amount of $269,129 are reflected as Accrued Revenues in Excess of Billings in the accompanying Consolidated Balance Sheet.
