INCOME TAXES	NOTE 13. INCOME TAXES Our effective tax rate for the three months ended June 30, 2019 was 29.2%, up from 24.4% for the three months ended June 30, 2018. Our effective tax rate for the six months ended June 30, 2019 was 28.6%, up from 25.7% for the six months ended June 30, 2018. The increase for the three and six months ended June 30, 2019, compared to the three and six months ended June 30, 2018, was primarily due to increased non-deductible expenses and higher effective state tax rates, partially offset by federal research and development credits. The change in the effective tax rate for the three and six months ended June 30, 2019 also reflects the impact of discrete events including the recognition of excess tax benefits related to employee stock compensation. Gross unrecognized tax benefits, included in Other long-term liabilities in the consolidated balance sheets, were $616,000 and $555,000 as of June 30, 2019 and December 31, 2018, respectively. The gross unrecognized tax benefits, if recognized by the Company, will result in a reduction of approximately $544,000 to the provision for income taxes thereby favorably impacting the Company’s effective tax rate. We do not anticipate our total unrecognized tax benefits to increase or decrease materially within the next twelve months. We recognize interest assessed by taxing authorities or interest associated with uncertain tax positions as a component of interest expense.
