The Company had $25.6 million and $16.1 million of unbilled revenues accrued as of June 30, 2019 and December 31, 2018, respectively, and such amounts are included within the trade accounts receivable balances above. Unbilled revenues are generally billed in the subsequent quarter to their revenue recognition.

In the fourth quarter of 2018, the Company recorded a reserve of $0.7 million for a renewable energy industry customer, based in part on the available information about the financial difficulties of the customer. This customer filed for a voluntary insolvency proceeding on April 9, 2019 at which time payments under the previously agreed upon payment plan ceased. As a result, during the first quarter of 2019, the Company recorded an additional charge of $5.7 million to fully reserve for the amount of the exposure related to this customer. During the second quarter, the Company reversed $1.0 million of this reserve based on additional information obtained during the quarter.

During the first six months of 2019, the Company sold to an unaffiliated third party, without recourse, its remaining outstanding receivables in an unrelated bankruptcy proceeding, which the Company had initially recorded as a charge during the second quarter of 2017. During the first quarter of 2019, the Company recorded a recovery of $0.2 million and during the six months ending June 30, 2019, the Company recorded a recovery $1.9 million, related to a bad debt provision related to this customer.
