Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring Charges In 2024, we recorded restructuring charges of $97 million ($73 million, net of tax or $0.64 per diluted share) related to actions in conjunction with an enterprise-wide comprehensive program to optimize cost structure and expand margins. The charges included $92 million for severance benefits and $5 million for strategic advisory services related to the targeted severance actions. During 2025, we reversed $5 million of accruals primarily due to attrition without payment of severance. We expect the total cash expenditures associated with these restructuring actions to be $92 million. We paid $7 million and $17 million during the three and six months ended March 31, 2026, respectively. We paid $12 million and $26 million during the three and six months ended March 31, 2025, respectively. Accruals remaining under these restructuring actions were $10 million and $27 million at March 31, 2026, and September 30, 2025, respectively.
