The majority of the variance from the statutory tax rate in 2022 is due to the tax benefit associated with the reversal of net deferred tax liabilities related to businesses no longer held for sale and the release of valuation allowances related to the utilization of capital loss carryforwards. These were partially offset by nondeductible goodwill associated with the sale of Inliner and the impact of the relative change in income before income taxes to the provision for income taxes.
