Hosting Arrangements	12. Hosting Arrangements In the fourth quarter of 2018 we began a process and technology transformation project that will, among other things, upgrade or replace our existing ERP, supply chain and inventory management systems and expand the remote monitoring capabilities of our compression fleet. Included in this project are hosting arrangements that are service contracts related to the cloud migration of our ERP system and cloud services for our new mobile workforce, telematics and inventory management tools. As of December 31, 2020 and 2019, we had $7.7 million and $5.5 million, respectively, of capitalized implementation costs related to our hosting arrangements that are service contracts included in other assets in our consolidated balance sheets. Accumulated amortization was $0.3 million at December 31, 2020. We recorded $0.3 million of amortization expense to SG&A in our consolidated statements of operations during the year ended December 31, 2020. During the year ended December 31, 2020, we impaired $1.6 million of capitalized implementation costs related to the hosting arrangements of the mobile workforce component of our project due to the termination of the agreement, which was included in long-lived and other asset impairment in our consolidated statements of operations.
