(1)

The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2016 compared to the third quarter of 2016 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2016 compared to the third quarter of 2016 of approximately $24,600, a charge of $14,000 recorded in the third quarter of 2016 associated with the anticipated loss on disposal of the Australia Divestment Business, which occurred on October 31, 2016 (as described in Note 6), and a decrease in loss on foreign currency transaction losses recorded in the fourth quarter of 2016 compared to the third quarter of 2016 of approximately $5,600.

(2) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2017 compared to the third quarter of 2017 is primarily attributable to increases in operating expenses, primarily associated with increased Recall Costs and bad debt expenses, as well as a $3,011 intangible impairment charge recorded during the fourth quarter of 2017. This increase in operating expenses was partially offset by a decrease in debt extinguishment expense in the fourth quarter of 2017 compared to the third quarter of 2017 of approximately $18,200, as well as a decrease in the provision for income taxes recorded in the fourth quarter of 2017 compared to the third quarter of 2017 of approximately $5,800. The decrease in the tax provision is primarily attributable to benefits derived from (i) rate changes as a result of the Tax Reform Legislation, (ii) the release of reserves and benefits recorded as a result of closing tax years; and (iii) the change in our estimated annual effective tax rate, which were partially offset by a provision related to the establishment of a valuation allowance on certain of our foreign net operating losses in Brazil.
