Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES The company accrues non income-tax liabilities for contingencies when management believes that a loss is probable and the amounts can be reasonably estimated, while contingent gains are recognized only when realized. In the event any losses are sustained in excess of accruals, they will be charged against income at that time. Attorney fees are recorded as incurred. Commitments represent obligations, such as those for future purchases of goods or services, that are not yet recorded on the company’s balance sheet as liabilities. The company records liabilities for commitments when incurred (i.e., when the goods or services are received). Contingent Liabilities Linde is subject to various lawsuits and government investigations that arise from time to time in the ordinary course of business. These actions are based upon alleged environmental, tax, antitrust and personal injury claims, among others. Linde has strong defenses in these cases and intends to defend itself vigorously. It is possible that the company may incur losses in connection with some of these actions in excess of accrued liabilities. Management does not anticipate that in the aggregate such losses would have a material adverse effect on the company’s consolidated financial position or liquidity; however, it is possible that the final outcomes could have a significant impact on the company’s reported results of operations in any given period. Significant matters are: •During 2009, the Brazilian government published Law 11941/2009 instituting a new voluntary amnesty program (“Refis Program”) which allowed Brazilian companies to settle certain federal tax disputes at reduced amounts. During 2009, the company decided that it was economically beneficial to settle many of its outstanding federal tax disputes and such disputes were enrolled in the Refis Program, subject to final calculation and review by the Brazilian federal government. The company recorded estimated liabilities based on the terms of the Refis Program. Since 2009, Linde has been unable to reach final agreement on the calculations and initiated litigation against the government in an attempt to resolve certain items. Open issues relate to the following matters: (i) application of cash deposits and net operating loss carryforwards to satisfy obligations and (ii) the amount of tax reductions available under the Refis Program. It is difficult to estimate the timing of resolution of legal matters in Brazil. •At December 31, 2023, the most significant non-income tax claims in Brazil, after enrollment in the Refis Program, relate to state VAT tax matters. The total estimated exposure relating to such claims, including interest and penalties, as appropriate, is approximately $115 million. Linde has not recorded any liabilities related to such claims based on management judgment and opinions of outside counsel. During the first quarter of 2023, the Brazilian Supreme Court issued a decision confirming the constitutionality of a specific federal income tax, with retroactive effect. As a result of this decision, the company recorded a reserve based on its best estimate of potential settlement (see Note 3). This decision has not yet been finalized and is subject to ongoing motions for clarification. Because litigation in Brazil historically takes many years to resolve, it is very difficult to estimate the timing of resolution of these matters; however, it is possible that certain of these matters may be resolved within the near term. The company is vigorously defending against the proceedings. •On September 1, 2010, CADE (Brazilian Administrative Council for Economic Defense) announced alleged anticompetitive activity on the part of five industrial gas companies in Brazil and imposed fines. CADE imposed a civil fine of R$1.7 billion Brazilian reais ($350 million) on White Martins, the Brazil-based subsidiary of Linde Inc., and R$0.2 billion Brazilian reais ($41 million) on Linde Gases Ltda., the former Brazil-based subsidiary of Linde AG, which was divested to MG Industries GmbH on March 1, 2019 and with respect to which Linde provided a contractual indemnity. The fine against White Martins and Linde Gases Ltda. was overturned by the Ninth and Seventh Federal Courts of Brasilia, respectively. CADE appealed these decisions, and the Federal Court of Appeals rejected CADE's appeals and confirmed the decision of the Ninth and Seventh Federal Courts of Brasilia. CADE had filed appeals for both subsidiaries with the Superior Court of Justice which were denied. CADE filed subsequent appeals to a panel of the Supreme Court of Justice and final and binding decisions were issued by the Supreme Court of Justice annulling the fine imposed against Linde Gases Ltda and White Martins in September 2023 and January 2024, respectively. •On and after April 23, 2019 former shareholders of Linde AG filed appraisal proceedings at the District Court (Landgericht) Munich I (Germany), seeking an increase of the cash consideration paid in connection with the previously completed cash merger squeeze-out of all of Linde AG’s minority shareholders for €189.46 per share. Any such increase would apply to all 14,763,113 Linde AG shares that were outstanding on April 8, 2019, when the cash merger squeeze-out was completed. The period for plaintiffs to file claims expired on July 9, 2019. In November 2023, the court issued a decision rejecting the plaintiffs’ claims in their entirety and determining that the cash merger squeeze-out consideration was appropriate. The plaintiffs are entitled to appeal this decision. The company believes the consideration paid was fair and that the claims are not supported by sufficient evidence, and no reserve has been established. We cannot estimate the timing of resolution. •On December 30, 2022, the Russian Arbitration Court of the St. Petersburg and Leningrad Region ("St. Petersburg Court") issued an injunction preventing (i) the sale of any shares in Linde’s subsidiaries and joint ventures in Russia, and (ii) the disposal of any of the assets in those entities exceeding 5% of the relevant company’s overall asset value. The injunction was requested by RusChemAlliance (RCA) as a preliminary measure to secure payment of a possible eventual award under an arbitration proceeding RCA intended to file against Linde Engineering for alleged breach of contract under the agreement to build a gas processing plant in Ust Luga, Russia entered into between a consortium of Linde Engineering, Renaissance Heavy Industries LLC, and RCA on July 7, 2021. Performance of the agreement was lawfully suspended by Linde Engineering on May 27, 2022 in compliance with applicable sanctions and in accordance with a decision by the sanctions authority in Germany. On March 1, 2023, RCA filed a claim in St. Petersburg against Linde GmbH for recovery of advance payments under the agreement ("Russian Claim"), and subsequently (i) added Linde and other Linde subsidiaries as defendants, and (ii) is seeking payment of alleged damages from Linde (pursuant to corporate guarantees) and guarantor banks. On March 4, 2023, in accordance with the dispute resolution provisions of the agreement, Linde GmbH filed a notice of arbitration with the Hong Kong International Arbitration Centre ("HKIAC") against RCA to claim that (i) RCA has no entitlement to payment, (ii) RCA’s Russian claim is in breach of the arbitration agreement which requires HKIAC arbitration, and (iii) RCA must compensate Linde for the losses and damages caused by the injunction. Additionally, Linde GmbH filed for and on March 17, 2023 obtained an anti-suit injunction from a Hong Kong court against RCA directing RCA to seek a stay of the Russian Claim and ordering it to resolve any disputes in accordance with HKIAC arbitration. On September 27, 2023, the anti-suit injunction was confirmed by the same Hong Kong court. On January 4, 2024, the Hong Kong court issued a final judgment in Linde’s favor (i) granting a permanent anti-suit injunction against RCA, (ii) granting a permanent, global anti-enforcement injunction against RCA, and (iii) ordering that the injunction issued by the St. Petersburg Court be lifted. As of December 31, 2023, Linde has a contingent liability of $1.1 billion recorded in Other long-term liabilities, which represents advance payments previously recorded in contract liabilities as of December 31, 2022 related to terminated engineering projects with RCA. As a result of the contract terminations, Linde no longer has future performance obligations for these projects. Linde deconsolidated its Russian gas and engineering business entities as of June 30, 2022, and the remaining investment value of its Russia subsidiaries is immaterial. Despite the January 4, 2024 decision of the Hong Kong court, the injunction affecting Linde’s shares and assets has not been lifted, the proceeding in St. Petersburg has not been stayed and RCA is continuing to pursue its claim in Russia. On February 20, 2024, the St. Petersburg Court issued its decision and granted the Russian Claim in RCA’s favor. Linde has 30 days to appeal this decision and expects to do so prior to the expiration of that deadline. If Linde appeals, RCA cannot enforce the decision (including foreclosing on the shares of the Russian entities) until after the appeal is decided. Linde does not expect an adverse impact on earnings from this decision given the contingent liability recorded as of December 31, 2023 and the immaterial remaining investment value of its deconsolidated Russia subsidiaries. It is difficult to estimate the timing of resolution of this matter. The company intends to vigorously defend its interests in both the Russian Claim and arbitration proceedings. Commitments At December 31, 2023, Linde had undrawn outstanding letters of credit, bank guarantees and surety bonds valued at approximately $3,344 million from financial institutions. These relate primarily to customer contract performance guarantees (including plant construction in connection with certain on-site contracts), self-insurance claims and other commercial and governmental requirements, including non-U.S. litigation matters. Other commitments related to leases, tax liabilities for uncertain tax positions, long-term debt, other post retirement and pension obligations are summarized elsewhere in the financial statements (see Notes 4, 5, 11, and 16).
