The Company recorded a credit loss of </span><span style="background:#ffffff;">$11.6</span><span style="background:#ffffff;"> million net of income tax in conjunction with the adoption of Topic 326.

As of December 31, 2021, the Company had gross receivables of $86.2 million in current assets and gross receivables of $230.7 million in other long-term assets. The Company has established credit loss reserves based on publicly available historic default rates issued by a third party for companies with similar credit ratings, factoring in the term of the respective accounts receivable or note receivable.
