Contract Assets and Contract Liabilities

    Contract assets relate to unbilled amounts arising from goods that have already been transferred to the customer where the right to payment is not conditional on the passage of time. This results in recognition of an asset, as the amount of revenue recognized at a certain point in time exceeds the amount billed to the customer. Contract assets are recorded in receivables within our Condensed Consolidated Balance Sheets and were not material as of May 31, 2021, or August 31, 2020.

    Contract liabilities relate to advance payments from customers for goods and services that we have yet to provide. Contract liabilities of $318.8 million and $139.1 million as of May 31, 2021, and August 31, 2020, respectively, are recorded within other current liabilities on our Condensed Consolidated Balance Sheets. For the three months ended May 31, 2021 and 2020, we recognized revenues of $34.2 million and $50.5 million related to contract liabilities, respectively. For the nine months ended May 31, 2021 and 2020, we recognized revenues of $126.2 million and $182.0 million related to contract liabilities, respectively. These amounts were included in the other current liabilities balance at the beginning of the respective periods.
