Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Ordinary Business Litigation Delphi Technologies is from time to time subject to various legal actions and claims incidental to its business, including those arising out of alleged defects, alleged breaches of contracts, product warranties, intellectual property matters, and employment-related matters. It is the opinion of Delphi Technologies that the outcome of such matters will not have a material adverse impact on the consolidated financial position, results of operations, or cash flows of Delphi Technologies. With respect to warranty matters, although Delphi Technologies cannot ensure that the future costs of warranty claims by customers will not be material, Delphi Technologies believes its established reserves are adequate to cover potential warranty settlements. Brazil Matters Delphi Technologies conducts business operations in Brazil that are subject to the Brazilian federal labor, social security, environmental, tax and customs laws, as well as a variety of state and local laws. While Delphi Technologies believes it complies with such laws, they are complex, subject to varying interpretations, and the Company is often engaged in litigation regarding the application of these laws to particular circumstances. As of June 30, 2018, the majority of claims asserted against Delphi Technologies in Brazil relate to such litigation. The remaining claims in Brazil relate to commercial and labor litigation with private parties. As of June 30, 2018, claims totaling approximately $16 million (using June 30, 2018 foreign currency rates) have been asserted against Delphi Technologies in Brazil. As of June 30, 2018, the Company maintains accruals for these asserted claims of $4 million (using June 30, 2018 foreign currency rates). The amounts accrued represent claims that are deemed probable of loss and are reasonably estimable based on the Company’s analyses and assessment of the asserted claims and prior experience with similar matters. While the Company believes its accruals are adequate, the final amounts required to resolve these matters could differ materially from the Company’s recorded estimates and Delphi Technologies’ results of operations could be materially affected. The Company estimates the reasonably possible loss in excess of the amounts accrued related to these claims to be zero to $12 million. Environmental Matters Delphi Technologies is subject to the requirements of U.S. federal, state, local and non-U.S. environmental and safety and health laws and regulations. As of June 30, 2018 and December 31, 2017, the undiscounted reserve for environmental investigation and remediation was approximately $4 million (of which $1 million was recorded in accrued liabilities and $3 million was recorded in other long-term liabilities) and $4 million (of which $1 million was recorded in accrued liabilities and $3 million was recorded in other long-term liabilities), respectively. Delphi Technologies cannot assure that environmental requirements will not change or become more stringent over time or that its eventual environmental remediation costs and liabilities will not exceed the amount of its current reserves. In the event that such liabilities were to significantly exceed the amounts recorded, Delphi Technologies’ results of operations could be materially affected. At June 30, 2018, the difference between the recorded liabilities and the reasonably possible range of potential loss was not material.
