Income Taxes	Income Taxes The Company's combined effective income tax rates were 16.7% and 23.1% for the three-month periods ended June 30, 2020 and 2019, respectively. The Company's combined effective tax rates were (12.4)% and 22.3% for the six-month periods ended June 30, 2020 and 2019, respectively. The Company's effective tax rate for June 30, 2020 includes the effect of state income taxes, a benefit for federal and state research and development credits, a net benefit for international provisions of US tax reform that became effective in 2018, and various discrete items with the largest being a benefit for the NOL carryback noted below. The Company's recorded liability for uncertain tax positions as of June 30, 2020 has increased by approximately $0.6 million, as compared to December 31, 2019 due to exposure related to federal and state credits, plus additional taxes and interest on existing reserves. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted and signed into law. Certain provisions of the CARES Act impact the 2020 income tax provision computations of the Company and are reflected in the period ended June 30, 2020. The CARES Act contains modifications to Net Operating Loss (“NOL”) carryback provisions, which will allow the Company to carryback its 2018 NOL recorded at a 21% statutory tax rate to prior tax years. This carryback to tax years with a higher statutory rate (35)% results in a net discrete tax benefit of $9.5 million for the year-to-date period.
