Credit Risk	12 Months Ended
Dec. 31, 2021
Risks and Uncertainties [Abstract]
Credit Risk	4. Credit Risk We are potentially subject to concentrations of credit risk in our accounts receivable. Credit risk with respect to receivables is limited due to the number of companies comprising our customer base. However, we did identify a potentially uncollectable account at December 31, 2019 and maintained a reserve for this receivable balance of $123. At December 31, 2020, the account was deemed uncollectable and offset against the reserve. At December 31, 2021, we did have two customers that accounted for 33% of total receivables. We deemed these accounts fully collectable. We did not have any potentially uncollectable accounts at December 31, 2021 and therefore, did not record a reserve for uncollectable accounts at December 31, 2021. We do not require collateral or other securities to support its accounts receivable.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
