Guarantees and Product Warranties [Abstract]  
Warranties
8. Warranties

We provide warranties on parts and labor related to our products. Our warranty terms range from two to five years. Warranty reserves are established for costs that are estimated to be incurred after the sale, delivery and installation of the products under warranty. The warranty reserves are determined based on known product failures, historical experience and other available evidence, and are included in accrued liabilities in our unaudited condensed consolidated balance sheets. Our warranty reserve balance was $4.9 million and $2.4 million, respectively, as of March 31, 2018 and December 31, 2017. Changes between March 31, 2018 and December 31, 2017 relate to the accounting impact of the transition of one of our agreements to the airline-directed model. See Note 1, “Basis of Presentation” for additional information.
