The Product Development and Tooling Costs of $2,416,910 have been expensed or capitalized, a portion of which will be amortized over future production of a specified number of units when the project is completed and commercially released. The Company expects amortization to commence in the first quarter of 2026.

The Company has warranty obligations in connection with the sale of certain of its products. The warranty period for its products is generally twelve (12) months, unless the customer purchases an extended warranty for an additional twelve (12) months. The costs incurred to provide for these warranty obligations are estimated and recorded as an accrued liability at the time of sale. The Company estimates its future warranty costs based upon product-based historical performance rates and related costs to repair.

The changes in the Company’s accrued warranty obligations for the years ended December 31, 2025, 2024, and 2023 were as follows:
