Income Taxes

Income Tax Expense

Our effective income tax rate was an expense of 29% and 34% for the three and six months ended June 30, 2022, respectively, as compared to a benefit of under 1% and 20% for the three and six months ended June 30, 2021, respectively. Our income tax rate for the three and six months ended June 30, 2022 was primarily impacted by changes in our valuation allowance against our net deferred tax assets, non-deductible executive compensation, the foreign derived intangible income deduction, the research and development tax credit, changes in our uncertain tax position liabilities, and tax shortfalls on stock compensation. Our income tax rate for the three and six months ended June 30, 2021 was primarily impacted by non-deductible executive compensation, changes in our valuation allowance against our net deferred tax assets, changes in our uncertain tax position liabilities, the research and development tax credit, and excess tax benefits on stock compensation.

Deferred Income Taxes

We generate deferred tax assets primarily as a result of finance leases, net operating losses, amortization of research and development expenses, excess interest carryforward, stock compensation, and accrued compensation. Our deferred tax liabilities are primarily made up of intangible assets acquired in previous years, finance leases, and unrealized gains and losses.

We maintained a net deferred tax liability of $22.7 million and $26.4 million as of June 30, 2022 and December 31, 2021, respectively. Our valuation allowance against our deferred tax assets was $16.2 million and $13.3 million as of June 30, 2022 and December 31, 2021, respectively, primarily related to net operating loss carryforwards and disallowed excess interest carryforwards.
