Note 7 - Commitments and Contingencies
General. We are periodically involved in litigation proceedings. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, then we accrue the estimated amount. The results of litigation proceedings cannot be predicted with certainty. We could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid and/or accrued. Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures for which we can estimate would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures.
Any loss estimates are inherently subjective, based on currently available information, and are subject to management’s judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal proceedings, actual results may differ materially from any amounts that have been accrued. At December 31, 2021, we had no amounts accrued for outstanding legal matters.
Purchase Commitments. We have entered into certain purchase commitments primarily related to our growth capital projects. At December 31, 2021, our purchase commitments totaled approximately $18.7 million, and are expected to occur over the next twelve months.
