8. Commitments and Contingencies
Tax Matters
We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to assessment and audit by the taxing authorities, it is possible that an assessment or audit could result in additional taxes due. We accrue for additional taxes when we determine that it is probable that we will have incurred a liability and we can reasonably estimate the amount of the liability. On June 16, 2022, Cause Number CV20-09-372, styled Solaris Oilfield Site Services v. Brown County Appraisal District, was presented to the 35th District Court of Brown County, Texas. The 35th District Court of Brown County ruled in favor of Brown County Appraisal District regarding the disqualification of our equipment for certain property tax exemptions. While we intend to vigorously appeal this ruling, we have recognized $3.1 in accrued liabilities as of March 31, 2023. No additional contingencies were recognized during the three months period ended March 31, 2023. If this litigation is ultimately resolved against us, in whole or in part, it is possible that the resolution of this matter could be material to our consolidated results of operations or cash flows.
