Commitments and Contingencies Tax Matters From time to time, we are under review by various domestic and foreign tax authorities with regard to indirect tax matters and are involved in various challenges and litigation in a number of countries, including, in particular, Brazil and South Korea, where the amounts under controversy may be material. We believe that these assessments are without merit and are currently appealing the actions. During the quarter ended December 31, 2016, the Korean branch of one of our subsidiaries received assessments of approximately $9.7 million (KRW 11.3 billion) and during the quarter ended June 30, 2017, an assessment for an additional $17.3 million (KRW 20.1 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 that these assessments are without merit and are currently appealing the actions. We are also involved in a number of 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 appealing an assessment of approximately $8.7 million (BRL 49.1 million) from the Brazilian tax authorities relating to the ICMS rate used for certain transactions. The assessment primarily consists of interest and penalties. We believe that the assessment is without merit and are pursuing our remedies in the judicial court system. 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. Other Matters 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. We have established loss provisions for these ordinary course claims as well as other matters in which losses are probable and can be reasonably estimated. As of September 30, 2020, we had recorded certain reserves that were not material. For those matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which exposure to loss in excess of the amount accrued is reasonably possible, we believe that such losses will not have a material adverse effect on our 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 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.
