The lower effective tax rate for the three months ended March 31, 2016, is primarily due to the effects of the impairment charges recorded in the prior year quarter.  The lower effective tax rate for the nine months ended March 31, 2017, is primarily related to the discrete tax impacts attributable to the Company’s Andacollo transactions and the liquidation of our Chilean subsidiary in the prior year.
