INCOME TAXES
INCOME TAXES	11. INCOME TAXES Our unrecognized tax benefits as of March 31, 2020 and December 31, 2019 were $4.9 million. The net amount of unrecognized tax benefits that, if recognized, would result in an impact to the effective tax rate is $4.7 million as of March 31, 2020 and December 31, 2019. We do not expect any material change in our unrecognized tax benefits during the remainder of 2020. Our practice is to recognize interest and penalties related to income tax matters in interest expense and selling, general and administrative expenses, respectively. As of March 31, 2020, we did not have a material liability for interest or penalties and had no material interest or penalty expense. The periods subject to examination for our federal return are years 2016 through 2018. The periods subject to examination for our state returns are years 2015 through 2018. In addition, prior tax years may be subject to examination by federal or state taxing authorities if the Company’s net operating loss carryovers from those prior years are utilized in the future. We are currently under examination by state taxing authorities. We do not expect any settlement or payment that may result from the examination to have a material effect on our results or cash flows. Our effective tax rate was 24.4% and 30.4% for the quarters ended March 31, 2020 and 2019, respectively. The effective tax rate differed from the federal and state statutory rates primarily due to various permanent income tax differences and differences in allocable income for the Company’s state tax filings. As of March 31, 2020, the CARES Act did not have a material impact on the Company's income tax positions. We will continue to evaluate the impact of enacted and future legislation.
