Accounting Changes and Error Corrections [Abstract]

New Accounting Standards

New Accounting Standards

Accounting standards implemented during fiscal year 2022

On October 1, 2021, the company adopted Accounting Standards Update ("ASU") 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Subtopic 815-40). As a result of adopting this ASU, entities are no longer required to separately present in equity an embedded conversion feature in such debt and instead should account for a convertible debt instrument wholly as debt. ASU 2020-06 also amended the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments.

The company elected to adopt the ASU using the modified retrospective method. The cumulative effect of the changes following implementation on October 1, 2021 was as follows:

	Balance at September 30, 2021		Adjustments Upon Adoption of ASU 2020-06		Balance at October 1, 2021
Liabilities
Long-Term debt	$	1,008	$	23	$	1,031
Equity
Additional paid-in capital	$	798	$	(40)	$	758
Retained earnings	$	935	$	17	$	952

The prior period consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for that period. Interest expense recognized in future periods will be reduced as a result of the derecognition of the unamortized debt discount on the 3.25 Percent Convertible Notes (see Note 13), which will no longer be amortized to interest expense. The reduction in interest expense will have a favorable impact on both basic and diluted earnings per share.

Inventories

InventoriesInventories are stated at the lower of cost (using FIFO or average methods) or market (determined on the basis of estimated realizable values)

Environmental

Environmental

 Federal, state and local requirements relating to the discharge of substances into the environment, the disposal of hazardous wastes and other activities affecting the environment have, and will continue to have, an impact on the operations of the company. The process of estimating environmental liabilities is complex and dependent upon evolving physical and scientific data at the sites, uncertainties as to remedies and technologies to be used and the outcome of discussions with regulatory agencies. The company records liabilities for environmental issues in the accounting period in which they are considered to be probable and the cost can be reasonably estimated. At environmental sites in which more than one potentially responsible party has been identified, the company records a liability for its allocable share of costs related to its involvement with the site, as well as an allocable share of costs related to insolvent parties or unidentified shares. At environmental sites in which Meritor is the only potentially responsible party, the company records a liability for the total probable and estimable costs of remediation before consideration of recovery from insurers or other third parties.
