The Company’s performance obligations are satisfied at a point in time. With the reclassification of our Superform business as discontinued operations, none of the Company's revenue is satisfied over time. As a result, the Company's contract receivables, contract assets and contract liabilities are included within current assets and liabilities held-for-sale.
