Quarterly Financial Information - Unaudited Quarterly Financial Information – Unaudited
In the opinion of management, the following unaudited quarterly data for the fiscal years ended October 3, 2021 and September 27, 2020 reflect all adjustments necessary for a fair statement of the results of operations.
In the fourth quarter of fiscal 2021 we recognized a non-recurring net tax benefit of $21.6 million primarily consisting of valuation allowances in the United Kingdom that were released due to sufficient positive evidence being obtained.
In the second quarter of fiscal 2020, we incurred incremental costs totaling $8.2 million to address the COVID-19 pandemic. In the fourth quarter of fiscal 2020, we recorded adjustments to our contingent earn-out liabilities and reported related net gains in operating income of $13.5 million. Additionally, we recorded a $15.8 million goodwill impairment charge related to the ASP reporting unit, which is in our CIG segment. We sold non-core equipment related to the disposal of our Canadian turn-key pipeline activities throughout fiscal 2020 which resulted in gains of $0.8 million, $2.2 million, $4.5 million, and $1.0 million in the first, second, third, and fourth quarters of fiscal 2020, respectively.
