The two yields above are different measurements and are not interchangeable. The forward yield annualises the last regular payment; the trailing 12-month yield counts the cash actually paid over the last 365 days. Neither is an interest rate, a bond's yield to maturity or an index effective yield, and none of those may be compared with these as like for like. See how we compute these numbers.

Our stored payment history for IRM begins in 2010. The run of increases above ends inside that history rather than at its edge, so the figure is measured within what we hold and is not a floor. A streak is counted on the split-adjusted payment, so a share split does not read as a cut.

A yield is just a payment divided by a price, so it moves every day even when the payment does not. The forward number is an estimate of the next twelve months; the trailing number is what was actually paid over the last twelve. Ex-date is the cut-off: own the shares before it and the next payment is yours, buy on or after it and the seller keeps it.

How to read this table: one row is one payment, newest at the top, and the amount is what a single share received on that one date. It is not an annual figure — the yearly ones are in the tiles above and in the totals further down. A row marked Special is a one-off the issuer chose to make rather than part of the regular schedule, which is why it is left out of the year-on-year comparison and out of those yearly totals. Whether the amount repeats for several rows or moves every time is a fact about the structure rather than a sign of health: a company usually resets its dividend once a year, while a fund's distribution can change with every payment.

The cadence column is the tag our provider attached to that individual payment (fmp), not the security's established schedule. The two can disagree, which is why the cadence shown in the tiles above is only accepted after three consecutive payments were tagged the same way.

A blank comparison means there was no comparable payment within sixty days of the same point a year earlier — a new payer, a changed cadence, or a gap in the record. Special and one-off payments are labelled and are excluded from the comparison.

Each bar, and each row underneath it, is one calendar year of regular payments added together for a single share. Read left to right and you are reading whether the payment has grown, held or been cut — a record of what was paid, never a forecast of what will be. One thing to watch for: a year here is decided by the date the payment went ex, so when that date slips across a year end one year holds an extra payment and its neighbour is one short while the payment itself never moved. Any year where that has happened is drawn as a dashed bar and marked with an asterisk, and it is the usual reason these totals differ from the annual figure the issuer itself publishes.

These are not the best-paying securities of this kind, and no ranking is meant by the order. They are the ones whose trailing 12-month yield sits nearest to this one, in the same structure and usually the same sector, so that this security can be seen in company rather than on its own. Every figure here is backward-looking cash that has already been paid. A row that sits well away from the rest is a question to take to that security's own page, not an answer.

Every row in this table is on the same basis — cash actually paid per share over the last 365 days, divided by that security's last price — so the column can be read down. Forward estimates are deliberately not used here, because they exist for some securities and not others and a mixed column would invite a comparison that does not hold. A dash means no payment was recorded in the last 365 days, or no price is on file. Open a security to see both of its yields.
