We classify reserves for tax uncertainties within accrued expenses and deferred credits and other in our Consolidated Condensed Balance Sheets, separate from any related income tax payable or deferred income taxes. Reserve amounts relate to any potential income tax liabilities resulting from uncertain tax positions as well as potential interest or penalties associated with those liabilities.

The effective tax rate for the quarter ended June 30, 2013 and 2012 was 35.6% and 39.6%, respectively. The effective rate benefit in the second quarter of 2013 was lower than 2012 primarily due to lower tax benefits from foreign operations.

The effective tax rate for the six months ended June 30, 2013 and 2012 was 51.3% and 37.0%, respectively. The effective rate benefit was higher for the first six months of 2013 primarily due to (i) a discrete tax benefit from a capital loss resulting from a tax election made for U.S. federal income tax purposes during the first quarter of 2013 which was retroactive to December 2012, (ii) retroactive U.S. tax law changes which were enacted in January 2013 and (iii) a favorable tax ruling in Israel received in February 2013.
We file income tax returns, including returns for our subsidiaries, with federal, state, and foreign jurisdictions. We are under regular and recurring audit by the Internal Revenue Service on open tax positions, and it is possible that the amount of the liability for unrecognized tax benefits could change during the next twelve months.
