Standard product warranty description | The Company generally provides warranties for its products. The standard warranty period is typically 12 months to 24 months for the Photonics and Precision Motion segments and 12 months to 36 months for the Vision segment. The standard warranty period for product sales is accounted for under the provisions of ASC 450, “Contingencies,” as the Company has the ability to ascertain the likelihood of the liability and can reasonably estimate the amount of the liability. |
