Income Taxes	Note 11 — Income Taxes Our provision for income tax expense was 25% and 33% of income before income taxes for the third quarters ended September 30, 2013 and 2012, respectively. The rate in the third quarter 2013 was lower than the statutory rate due primarily to certain discrete adjustments recorded during the quarter. The rate in 2012 did not include a benefit for the research credit because Congress had not yet extended the credit for that year at the time. For the nine-month period ended September 30, 2013, our income tax expense was 20% of income before income taxes compared to 38% for the same period of 2012. The rate for the first nine months of 2013 was positively impacted by tax law changes related to recently enacted legislation which lowered the corporate income tax rates in Denmark. In addition, the domestic tax law change related to research and development credits which was effective in the first quarter 2013 also positively affected the current year rate. The 2012 provision was higher than normal due primarily to the non-deductibility of certain expenses incurred in relation to the acquisition of Dansensor. As of September 30, 2013 and December 31, 2012, the liability for gross unrecognized tax benefits was $297,000 and $265,000, respectively. Changes in gross unrecognized tax benefits during the nine-months ended September 30, 2013 primarily consisted of an increase for tax positions taken in the current year. It is expected that the amount of unrecognized tax benefits for positions which the Company has identified will not materially change in the next twelve months.
