Note Receivable [Abstract]  
Note Receivable Note Receivable
In connection with the closure of our Canadian facility on May 18, 2009, we sold land and a building in September 2010 and assumed a note receivable from the borrower secured by the property. The C$1.1 million, 15 year note has an interest rate of 4.0% and is payable to us monthly, and has a C$0.6 million balloon payment due in October 2025. Interest payments are recognized in interest income. The current and long-term portions of this note receivable are included in other prepaid expenses and other and other long-term assets, respectively, on our balance sheet.

We evaluate the note for impairment on a quarterly basis. We determine the note receivable to be impaired if we are uncertain of its collectability based on the contractual terms. At December 31, 2021 and 2020, there was no impairment.
