The Company did not record any sales for the nine months ended November 30, 2020 or 2019 related to performance obligations satisfied in prior periods. The increases or decreases in accounts receivable, contract assets, and contract liabilities during the nine months ended November 30, 2020 and 2019 were due primarily to normal timing differences between the Company’s performance and customer payments, divestitures, and, to a lesser extent, customer inspection delays and effects of COVID-19 on the Company's customers.

The Company expects to recognize sales, related to the $11.5 million balance of contract liabilities as of November 30, 2020 of approximately $2.2 million, $7.0 million and $2.3 million in fiscal 2021, 2022 and 2023, respectively.
