The Company’s effective tax rate (benefit) was (15.4%) and 23.7% for the six months ended June 30, 2020 and 2019, respectively. The following items caused the effective tax rate for the three and six months ended June 30, 2020 to be significantly different from the Company’s historical annual effective tax rate: ​
| ● | The Company recorded impairment of nondeductible goodwill related to the Municipal reporting unit. This decreased the rate by 8.4% and 7.5% for the three and six months ended June 30, 2020, respectively.
| ● | After an evaluation of recent profitability, future projections of profitability, and future deferred tax liabilities, the Company concluded that an additional valuation allowance of approximately $1,477 is necessary for certain state deferred tax assets. This decreased the rate by 0.3% and 0.2% for the three and six months ended June 30, 2020, respectively.
​ Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The largest item affecting deferred taxes is the difference between book and tax amortization of goodwill and other intangibles amortization.
