_______________________________________________________________________________

(1) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2014 compared to the third quarter of 2014 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2014 compared to the third quarter of 2014 of approximately $54,000. The decrease in the income tax provision was offset by a decrease in operating income of approximately $13,600, a debt extinguishment charge recorded in the fourth quarter of 2014 of approximately $16,500 and an increase in interest expense of $9,800. The decrease in operating income is attributable to a $8,300 increase in selling, general and administrative expenses, primarily due to higher professional fees and charitable contributions, as well as a $4,700 decrease in revenue, primarily due to unfavorable changes in foreign exchange rates, in the fourth quarter compared to the third quarter.

(2) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2015 compared to the third quarter of 2015 is primarily attributable to a debt extinguishment charge recorded in the fourth quarter of 2015 of approximately $25,100, an increase in the provision for income taxes recorded in the fourth quarter of 2015 compared to the third quarter of 2015 of approximately $6,800, as well as a decrease in operating income of approximately $3,600, primarily associated with a $1,800 write-off of certain property in our Western European Business segment. The debt extinguishment charge, the increase in the provision for income taxes and the decrease in operating income during the fourth quarter of 2015 was offset by a decrease in loss on foreign currency transaction losses recorded in the fourth quarter of 2015 compared to the third quarter of 2015 of approximately $18,100.
