Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company records provisions when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Claims and litigation are reviewed quarterly and provisions are taken or adjusted to reflect the status of a particular matter. The Company believes the estimated liability in its Condensed Consolidated Financial Statements for claims or litigation is adequate and appropriate for the probable and estimable outcomes. Liabilities recorded were not material to the Company’s financial position, results of operations or liquidity. The Company believes it is remote that the settlement of any of the currently identified claims or litigation will be materially in excess of what is accrued. Warranty Reserves The Company estimates warranty expense on certain products at the time of sale using quantitative measures based on historical warranty claim experience and evaluation of specific customer warranty issues. There were no individually or collectively material specific warranty matters accrued for, or significant settlements made, during the three months ended October 31, 2021 and 2020. The Company’s accrued warranty reserves were $5.9 million and $6.1 million as of October 31, 2021 and July 31, 2021, respectively.
