Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies On November 23, 2023, one of our subsidiaries submitted an erroneous bid in the Finnish power market. During the fourth quarter of 2023, the Company recognized related extraordinary losses totaling $48.8 million, which are principally reported within Cost of revenue on the Consolidated Statements of Income and Comprehensive Income. In December 2023, the subsidiary received a request for information from Energiavirasto, the Finnish energy regulatory authority ("EA"), indicating that EA had initiated an investigation in relation to the events surrounding the erroneous bid submission. We have since received requests for additional information following our responses to EA's initial requests. We have responded to such requests and continue to cooperate with the investigation. At this time, we are unable to predict the outcome of this investigation, including whether the investigation will result in any action, proceeding or fine against us. We are also a party to various claims, complaints and proceedings arising in the ordinary course of our business, including, but not limited to, environmental claims, commercial and governmental contract claims, such as property damage, demurrage, personal injury, billing and fuel quality claims, as well as bankruptcy preference claims and tax and administrative claims. From time to time, we are also under review by various domestic and foreign tax authorities regarding indirect tax matters and are involved in various challenges and litigation in a number of countries, including, in particular, South Korea and Brazil, where the amounts in controversy may be material. During 2016 and 2017, the South Korean branch of one of our subsidiaries received assessments totaling approximately $24.9 million (KRW 34.3 billion) from the regional tax authorities of Seoul, South Korea. The assessments primarily consist of fines and penalties for allegedly failing to issue Value Added Tax ("VAT") invoices and report certain transactions during the period 2011-2014. These assessments do not involve failure to pay or collect VAT. We believe we have substantial defenses to these assessments and expect to continue to pursue available administrative and judicial remedies to resolve this matter. We are also involved in several tax disputes with federal, state and municipal tax authorities in Brazil, relating primarily to a VAT tax known as ICMS. These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest. One of our Brazilian subsidiaries is currently contesting an assessment from the Brazilian tax authorities relating to the ICMS rate used for certain transactions (consisting of tax, interest and penalties) that now stands at approximately $5.8 million (BRL 32.5 million). In November 2023, the deadline passed for the Brazilian tax authorities to appeal a previous judgment reducing the interest rate applicable to the assessment. In April 2024, the Sao Paulo Court of Justice published a decision on a motion previously filed in the case, which reduced the penalty by limiting it to the total tax due and eliminated any interest that would have been due on the excess penalty. We intend to pursue available administrative and judicial remedies necessary to resolve this matter. We have established loss provisions for claims and other matters in which losses are probable and can be reasonably estimated. As of June 30, 2024, our reserves for such claims were not material. For those matters where a reserve has not been established and for which we believe a loss is reasonably possible, we believe that such losses will not have a material adverse effect on our Condensed Consolidated Financial Statements. However, any adverse resolution of one or more such claims, complaints or proceedings during a particular period could have a material adverse effect on our Condensed Consolidated Financial Statements or disclosures for that period. Our estimates regarding potential losses and materiality are based on our judgment and assessment of the claims utilizing currently available information. Although we will continue to reassess our reserves and estimates based on future developments, our objective assessment of the legal merits of such claims may not always be predictive of the outcome and actual results may vary from our current estimates. When we deem it appropriate and the amounts are reasonably estimable, we establish reserves for potential adjustments to our provision for the accrual of indirect taxes that may result from examinations or other actions by tax authorities. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities will result in the recognition of benefits in the period we determine the liabilities are no longer necessary. If our estimates of any of our federal, state, and foreign indirect tax liabilities are less than the ultimate assessment, it could result in a further charge to expense. Except with respect to the matters described above, we believe that the final outcome of any pending examinations, agreements, administrative or judicial proceedings will not have a material effect on our results of operations or cash flows.
