Hosting Arrangements	8. 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 June 30, 2021 and December 31, 2020, we had $9.8 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 condensed consolidated balance sheets. Accumulated amortization was $0.5 million and $0.3 million at June 30, 2021 and December 31, 2020, respectively. We recorded $0.1 million of amortization expense to SG&A in our condensed consolidated statements of operations during each of the three months ended June 30, 2021 and 2020, and $0.2 million and $0.1 million during the six months ended June 30, 2021 and 2020, respectively.
