Computed as the sum of the director compensation table rows above; inputs and formula shown in the register.

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.

Of the companies Iron Mountain Inc. names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.

Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including Iron Mountain Inc..

Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

Each peer's compensation is from its most recently filed proxy; fiscal years differ by company. Each peer's figures come from its own filings; the subject company is highlighted. Peers whose chief executive compensation is outside our coverage universe are stated as such, never left blank.

Read from each company's Compensation Discussion and Analysis: annual incentive payout as a percentage of target, the disclosed long-term vehicle mix, whether performance-share measures include a total shareholder return component, and the retained compensation consultant. “Not disclosed” appears only where the company's filing does not state the item.

Answers are drawn only from the figures disclosed in this brief and cited to their location in the source filing. Where a figure required for an answer is not disclosed, that is stated rather than estimated.

Each figure's location is given both for the eye (section · page · table · row · column) and for a script (table/row/column index and exact character span in the filed document). Any figure can be independently confirmed against the source.
