However, the Company generally has certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, the Company may take title to the underlying assets in lieu of cash in settlement of receivables. As of December 31, 2020 and 2019, none of the Company’s customers individually exceeded 10.0% of accounts receivable.
