[1] The increase in Net income, and basic and diluted earnings per share for the three and six months ended June 30, 2023 is primarily related to the release of a significant portion of the Company's valuation allowance for deferred tax assets that had been recorded as a result of the 2020 goodwill and intangible asset impairment.
