Contract Assets and Liabilities

A contract asset is a right to consideration in exchange for goods that the Company has transferred to a customer when that right is conditional on something other than the passage of time. A contract liability exists when the Company receives consideration in advance of performance obligations being satisfied. The Company has no contract assets or liabilities on its condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. For the three and nine months ended September 30, 2021 and 2020, revenue recognized from performance obligations related to prior periods was not material.
