For the 2016 second quarter, our unrecognized tax benefits balance of $32 million increased by $8 million from year-end 2015, consisting of $4 million for tax positions taken during the current period and a $4 million reserve due to a recent examination of a tax position taken in a foreign jurisdiction. The unrecognized tax benefits balance included $22 million of tax positions that, if recognized, would impact our effective tax rate.

As a result, our 2014 tax year audit is substantially complete. Our 2015 and 2016 tax year audits are currently ongoing.
