NEW YORK (S&P Global Ratings) March 12, 2017--S&P Global Ratings today assigned its 'BB' issue-level rating and '2' recovery rating to Iron Mountain Inc.'s proposed $500 million senior secured term loan B due 2026. The '2' recovery rating indicates our expectation for substantial recovery (70%-90%; rounded estimate: 75%) of principal in the event of a payment default. The company's subsidiary, Iron Mountain Australia Group Pty. Ltd., is also issuing an incremental 100 million Australian dollars (A$) term loan to its existing A$250 million term loan due in 2022. The 'BB' issue-level rating and '2' recovery rating on the Australian dollars term loan are unchanged. Iron Mountain will use the net proceeds from both the U.S. and the Australian dollar term
