Hosting Arrangements	12. Hosting Arrangements In the fourth quarter of 2018, we began a process and technology transformation project that has, among other things, replaced our existing ERP, supply chain and inventory management systems and expanded 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, 2021 and 2020, we had $12.7 million and $7.7 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 $0.7 million and $0.3 million at December 31, 2021 and 2020, respectively. We recorded $0.3 million of amortization expense to SG&A in our consolidated statements of operations during each of the years ended December 31, 2021 and 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.
