The Company had $21.0 million and $11.9 million of unbilled revenue accrued as of September 30, 2021 and December 31, 2020, respectively. These amounts are included in the trade accounts receivable balances above. Unbilled revenue is generally billed in the subsequent quarter to their revenue recognition. The Company considers unbilled receivables as short-term in nature as they are normally converted to trade receivables within 90 days, thus future changes in economic conditions will not have a significant effect on the credit loss estimate.

The Company was contracted to perform inspections of welds on various pipeline projects in Texas for a customer. As of December 31, 2019, approximately $1.4 million of past due receivables were outstanding from this customer. The Company received notice from the customer in December 2019, alleging that the work performed was not in compliance with the contract. The Company recorded a full reserve for this receivable during 2019 and the status of this situation has not changed since 2019. See Note 14-Commitments and Contingencies for additional details.
