Income Taxes	3. Income Taxes The effective tax rate for both the quarter and six months ended June 30, 2014 and 2013 reflected the discrete tax effect of litigation charges, primarily related to product liability claims, which were substantially incurred in a low tax jurisdiction. The effective tax rate for the current six month period also reflected a tax benefit of $10.9 million as a result of the completion of U.S. Internal Revenue Service (“IRS”) examinations for the tax years 2008 through 2010. The effective tax rate for the six months ended June 30, 2013 reflected the discrete tax effect of a write-down of an insurance receivable, which was also incurred in a low tax jurisdiction. See Note 6 of the notes to condensed consolidated financial statements. In addition, the tax provision for the six months ended June 30, 2013 was reduced by approximately $3.7 million to recognize the 2012 benefit of the American Taxpayer Relief Act of 2012, which was signed into law on January 2, 2013 and retroactively reinstated the research tax credit. At June 30, 2014, the total amount of liability for unrecognized tax benefits related to federal, state and foreign taxes was $31.5 million (of which $26.0 million would impact the effective tax rate, if recognized) plus $3.2 million of accrued interest. At December 31, 2013, the liability for unrecognized tax benefits was $58.0 million plus $6.6 million of accrued interest. Depending upon the result of open tax examinations and/or the expiration of applicable statutes of limitation, the company believes it is reasonably possible that the total amount of unrecognized tax benefits may decrease by up to $3.7 million within the next 12 months.
