As of March 31, 2020, the ASC business continued to be classified as held and used because all criteria for held-for-sale accounting and reporting as provided in Accounting Standards Codification 360, Property, Plant and Equipment, had not been met. Specifically, the planned sale of ASC is subject to certain contingencies including regulatory approval and other transaction terms and conditions yet to be resolved. On April 22, 2020, subsequent to the quarter ended March 31, 2020, regulatory approval for the sale was granted by the applicable governmental authorities. Subject to the resolution of any further transaction contingencies, the sale is expected to close in the second quarter of 2020.
